Discover the API Surface + +Find the public interface of what was implemented — but do NOT read the implementation body or the implementer's tests: + +```bash +# Find new or modified files (excluding test files) +git diff --name-only ..HEAD | grep -v '_test\.' | grep -v '.test\.' +``` + +For each file, read only the **type definitions, function signatures, and exported symbols** — enough to know how to call the code, not how it works internally. + +```bash +# For Go: extract type and function signatures +grep -n '^func \|^type \|^var \|^const ' +``` + +**Hard rule**: Do NOT read files matching `*_test.go`, `*.test.ts`, `*.test.js`, `*.spec.*`, or any file in a `testdata/` directory. These are the implementer's tests — seeing them would compromise your independence. + +### 3. Write Acceptance Tests + +For each expected behavior identified in step 1, write a test that exercises the implementation. These tests encode YOUR interpretation of the spec, not the implementer's. + +**Test strategy**: Choose the approach that best fits the project: +- **Binary/CLI tools**: Invoke the built binary as a subprocess with crafted inputs. This is preferred when a binary exists — it tests the real artifact without compiling into the project's test harness. +- **Libraries/APIs**: Write test files that import the public API and call it directly. You're in a worktree, so adding test files and dependencies is safe. +- **Either way**: Your tests verify behavior from the outside. Prefer the public API surface over reaching into internals. + +**Test design principles**: +- Each test maps to one expected behavior from the spec +- Use descriptive names that reference the spec: `TestCreateUser_ReturnsErrorWhenEmailEmpty` not `TestFunc1` +- Include the edge cases mentioned in the spec +- Include 1-2 edge cases NOT mentioned in the spec but implied by the domain (e.g., if the spec says "handles empty input," also test nil/null) + +### 4. Run Acceptance Tests + +```bash +# Run ONLY your acceptance tests, not the full suite +# Go example: +go test -run 'Acceptance' ./path/to/package/... +# Or run the specific file: +go test ./path/to/package/ -run 'TestXxx' +``` + +### 5. Analyze Results + +For each acceptance test: + +- **PASS**: The implementation satisfies this spec requirement from your independent perspective. Note it. +- **FAIL — Spec-Intent Gap**: Your interpretation of the spec differs from what was built. This is a finding. Describe what the spec says, what your test expected, and what actually happened. +- **FAIL — Missing Behavior**: The spec requires something that doesn't appear to be implemented at all. This is a critical finding. +- **FAIL — Edge Case**: An edge case the spec implies but doesn't explicitly state. Flag but mark as lower severity. +- **ERROR — Cannot Test**: The public API doesn't expose enough surface to test this behavior. This itself is a finding — if a spec requirement isn't testable through the public API, the interface may be incomplete. + +### 6. Report + +Report your findings to the dispatching agent. Do NOT commit or clean up — the worktree is discarded automatically. + +## Report Format + +``` +## Evaluation: PASS | CONCERNS | FAIL | BLOCKED + +### Implementation Health (pre-check) +- Project builds: PASS | FAIL +- Existing tests pass: PASS | FAIL +- Binary/API available: PASS | FAIL + +### Evaluator Setup (self-check) +- Acceptance test compilation: PASS | FAIL () +- Evaluator dependencies resolved: PASS | FAIL + +### Spec Coverage ( behaviors) +- [PASS] +- [PASS] +- [FAIL] — +- ... + +### Findings + +#### Spec-Intent Gaps (implementation differs from spec) +- **Behavior**: +- **Expected**: +- **Actual**: +- **Severity**: Critical | Important + +#### Missing Behaviors (spec requires, not implemented) +- **Behavior**: +- **Evidence**: +- **Severity**: Critical + +#### Edge Case Failures (implied by domain, not explicit in spec) +- **Case**: +- **Expected**: +- **Actual**: +- **Severity**: Important | Minor + +#### Untestable Requirements (spec requires, API doesn't expose) +- **Requirement**: +- **Issue**: +- **Severity**: Important + +### Summary +<2-3 sentence assessment: does the implementation faithfully satisfy the spec?> +``` + +**Verdicts**: +- `PASS` — all spec behaviors pass and no critical gaps found +- `CONCERNS` — edge cases fail or minor gaps exist but core behaviors work +- `FAIL` — spec-intent gaps or missing behaviors found +- `BLOCKED` — infrastructure failure prevented evaluation (tests didn't compile, binary missing, dependencies unresolvable). This is an evaluator problem, NOT an implementation problem — the orchestrator should not re-dispatch the implementer for BLOCKED results + +**Two health checks, two different meanings:** + +- **Implementation Health** failures are real findings. By the time the evaluator runs, the implementer's gate should have verified a clean build and passing tests. If the project doesn't build or existing tests fail, the implementer shipped broken work — report `FAIL` with the build/test failure as a Critical finding, not `BLOCKED`. +- **Evaluator Setup** failures are the evaluator's own problem. If your acceptance tests don't compile or your added dependencies don't resolve, that's not the implementer's fault — report `BLOCKED`. The orchestrator should not re-dispatch the implementer for `BLOCKED` results. + +## Discipline + +- **You are skeptical by default.** Your job is to find problems, not to validate. A "PASS" from you should mean something. +- **Spec is your source of truth.** If the implementation does something reasonable but different from the spec, that's a finding — the orchestrator decides whether to accept the deviation. +- **Independence is non-negotiable.** The moment you read the implementer's tests, you lose your value. Your tests must come from the spec alone. +- **Be concrete.** "Might not handle edge cases" is worthless. "TestCreateUser with empty email returns 200 instead of 400 per spec requirement 3" is actionable. +- **Separate your failures from theirs.** If the project doesn't build, that's the implementer's fault — report FAIL. If your own acceptance tests don't compile, that's YOUR problem — report BLOCKED.

Approaches with more cross-cutting concerns, more files touched, or tighter coupling between components will likely need `opus`-tier dispatches and more review cycles. Approaches that decompose cleanly into single-file, mechanical tasks will run on `haiku`/`sonnet` and iterate faster. This is a soft consideration, not a deciding factor — but the user should see it. + +### 4. Present Design Section by Section + +- Break the design into logical sections (data model, API, UI, etc.) +- Present each section and get user approval before moving to the next +- Iterate on sections as needed based on feedback + +**Design for isolation and clarity:** Break the system into smaller units that each have one clear purpose, communicate through well-defined interfaces, and can be understood and tested independently. For each unit, you should be able to answer three questions: what does it do, how do you use it, and what does it depend on. Smaller, well-bounded units are also easier for subagents to work with — they reason better about code they can hold in context at once, and their edits are more reliable when files are focused. If a file in the design is projected to grow large, that's often a signal that it's doing too much — consider splitting the responsibility at design time. + +**In existing codebases:** Follow existing patterns. Where existing code has problems that affect the work (e.g., a file that's grown too large, unclear boundaries, tangled responsibilities), include targeted improvements as part of the design — the way a good developer improves code they're working in. Don't propose unrelated refactoring. Stay focused on what serves the current goal. + +### 5. Identify Shared Contracts (Parallel Readiness) + +If the design will produce multiple implementation tasks that could run in parallel, explicitly identify the **shared contracts** — types, interfaces, config keys, constants, and function signatures that multiple tasks will reference. + +Contracts fall into two tiers: + +- **Shared contracts** (referenced by 2+ tasks): produce **exact, copy-pasteable code blocks** including the type definition AND a contract test assertion. The T0 foundation task will write these verbatim. +- **Task-internal types** (used within a single task): use typed pseudocode (e.g., `FeedbackRequest { memory_id: i64, rating: i8 }`) — the subagent adapts to language idioms during implementation. + +Present shared contracts to the user as a "foundation layer" with exact code: + +```go +// internal/types/config.go + +// SessionConfig holds session-related settings. +type SessionConfig struct { + Timeout time.Duration `json:"timeout"` + MaxIdle int `json:"max_idle"` + Secure bool `json:"secure"` +} +``` + +```go +// internal/storage/storage.go + +// GetSession retrieves a session by ID. +// Returns nil and no error if the session does not exist. +GetSession(ctx context.Context, id string) (*Session, error) +``` + +Contract test assertions verify that the shared types satisfy compile-time expectations. Place these **inline in each relevant test file** with a clear separator: + +```go +// internal/types/config_test.go + +// --- Contract assertions --- + +// Verify SessionConfig fields exist with expected types. +var _ time.Duration = SessionConfig{}.Timeout +var _ int = SessionConfig{}.MaxIdle +var _ bool = SessionConfig{}.Secure +``` + +```go +// internal/storage/sqlite/sqlite_test.go + +// --- Contract assertions --- + +// Verify SQLiteStore satisfies the Storage interface. +var _ storage.Storage = (*SQLiteStore)(nil) +``` + +These exact definitions and contract tests become the **T0 foundation task** during planning — implemented sequentially before any parallel work begins. The T0 task writes the shared type files and embeds contract test assertions inline in each relevant test file, so that parallel agents can import these types immediately and any drift is caught at compile time. + +**Skip this step** if the design maps to a single task or purely sequential work. + +### 5.5. Grill the Design (Optional Stress-Test) + +Before publishing the design for review, save the draft to disk and offer a stress-test pass. Both this step and step 6 need the design as a file on disk, so first: + +- **Write the design document** to `docs/plans/` using `YYYY-MM-DD-<topic>.md` naming. Do this whether or not the user opts into grilling — step 6 picks it up either way. + +Then run a relentless-interrogation pass that probes the drafted design for unresolved *internal* decisions before publishing. This is a distinct job from step 7's review loop: that one processes external reviewer feedback you receive back; this one finds gaps the design didn't fully resolve, which become expensive to fix once implementation starts — and prevents publishing a version that's already known to be incomplete. + +**When to recommend it.** This is opt-in. Mark "grill" as recommended when the design appears Medium/Large per the Scale Detection table (multiple work items, multiple layers crossed, or migrations/breaking changes). For Small-scale single-task work, default the recommendation to "skip" — the overhead isn't worth it. + +**Always recommend grilling when step 2 was foreclosed.** If the user shut down clarifying questions up front, this is the recovery loop — override the scale-based default and mark *"Yes, grill me"* as recommended regardless of how small the design looks. + +**Use the AskUserQuestion tool:** + +``` +Question: "Stress-test the design before publishing?" +Options: + - "Yes, grill me" — interrogate decisions one at a time until we converge + - "No, proceed" — skip to step 6 register for review +``` + +If "Yes", run the loop: + +**Loop rules:** + +- Walk the design's decision tree **depth-first, ordered by dependency**. Resolve decisions that constrain later answers first (e.g., "what storage layer?" before "how do we serialize sessions?"). When a resolution opens new branches, recurse into them before backtracking. +- **One question per turn** via `AskUserQuestion`. Mark the recommended option. When the choice is genuinely contested, offer 2-3 options; when one option is objectively dominant, a single recommendation is fine — but never rubber-stamp open questions just because you have an opinion. +- **Codebase-first rule.** Before each question, name the symbol, file, or pattern that would answer it. If you can name one, search first (Grep / Read / symbol search) and only ask when the codebase doesn't — or can't — answer. This is the single biggest difference from step 2's clarifying questions, where you don't yet have a draft to ground against. +- **Capture resolutions in-place.** Each resolved decision is an edit to `docs/plans/<file>.md` — update the relevant section, don't maintain a separate Q&A log. The design doc is the artifact. + +**Stop when ANY of:** + +- The user says "done", "enough", or "stop" +- Two consecutive rounds surface no new unresolved branches (the tree is exhausted) +- The loop has run ~10 rounds (hard cap — if you still have open branches at this point, surface them as a "remaining open questions" note in the design doc instead of asking another) + +Then proceed to step 6. + +### 6.

Stop escalating at opus — if opus also returns `BLOCKED`, escalate to the human with the subagent's blocker summary. + +## Dispatch Modes + +### Sequential (default) + +Tasks are dispatched one at a time through the orchestration loop below. Use this for: +- Most workflows — it's the safe default +- Tasks with any file overlap +- Tasks with dependency ordering (`blocks`/`blockedBy`) +- When you're unsure whether tasks are independent + +### Parallel + +Multiple tasks dispatched simultaneously using `isolation: "worktree"`. Use this **only** when ALL of these are true: +- 3+ independent tasks remain +- No shared files between any tasks in the batch +- No `blocks`/`blockedBy` dependencies between tasks in the batch +- Each task's scope is clearly defined with no ambiguity + +**When NOT to use parallel**: overlapping files, task dependencies, uncertainty about scope, fewer than 3 tasks. Default to sequential — the cost of serial execution is time; the cost of a bad parallel merge is data loss. + +## Orchestration Loop + +By default, use sequential dispatch. For independent tasks, see [Parallel Dispatch Protocol](#parallel-dispatch-protocol) below. + +**Task tracking**: At the start of implementation, create a task list using `TaskCreate` with one entry per arc issue to implement. This provides a visible progress tracker in the CLI. Update each task as you work: +- `in_progress` when dispatching the subagent +- `completed` when the task is closed in arc + +```bash +# Get the list of tasks to implement +arc list --parent=<epic-id> --status=open --json +``` + +Create a `TaskCreate` entry for each, then work through this loop: + +### 1. Find Next Task + +```bash +arc ready +# or for a specific epic: +arc list --parent=<epic-id> --status=open +``` + +### 2. Claim Task + +```bash +arc update <task-id> --take +``` + +### 3. Dispatch Agent + +Record the current HEAD before dispatching — needed for review if escalated: + +```bash +PRE_TASK_SHA=$(git rev-parse HEAD) +``` + +Check whether the task has a `docs-only` label: + +```bash +arc show <task-id> --json | jq -e '.labels[] | select(. == "docs-only")' > /dev/null 2>&1 +``` + +**If `docs-only`** (exit code 0) — spawn an `doc-writer` subagent: + +Use the template at `./doc-writer-prompt.md`. Fill placeholder `{TASK_ID}`. For docs-only work, the agent default (`haiku`) is correct — omit `model:` unless the docs task is unusually complex. + +**Otherwise** — spawn an `builder` subagent: + +Use the template at `./builder-prompt.md`. Fill placeholders (`{TASK_ID}`, `{PRE_TASK_SHA}`, `{DESIGN_EXCERPT}`) and apply Model Selection guidance (see `## Model Selection` above) for the dispatch `model:`. + +### 4. Evaluate Result + +When the subagent reports back, check its **Status** (one of `DONE | DONE_WITH_CONCERNS | BLOCKED | NEEDS_CONTEXT`) and **Gate Results**. Follow the `## Handle Implementer Status` table below for the status-specific action. In all cases, run the project test command fresh yourself — do NOT trust the subagent's report alone. + +**On `DONE`:** +- Run the project tests. If they pass → proceed to step 5 (Spec Compliance Review). +- If tests fail despite a `DONE` report, treat as `BLOCKED`: re-dispatch with the failure output. + +**On `DONE_WITH_CONCERNS`:** +- Read the concerns carefully. +- If the concerns touch correctness or scope (e.g., "I think this edge case isn't handled", "I modified a file outside the spec") — address before review by re-dispatching with specific guidance, or tightening the review prompt. +- If the concerns are observations (e.g., "this file is getting large") — note them as arc comments on the task and proceed to step 5. + +**On `BLOCKED` or `NEEDS_CONTEXT`:** +- Do NOT proceed to review. Do NOT close the task. +- For `NEEDS_CONTEXT`: gather the requested information, re-dispatch with it. +- For `BLOCKED`: assess the blocker per the Handle Implementer Status table. Escalate one model tier (haiku → sonnet → opus) per the Model Selection escalation rule, or invoke the `debug` skill if the blocker is a persistent test failure, or split the task if too large, or escalate to the human. +- After 3 re-dispatches on the same task without clean `DONE`, invoke the `debug` skill. + +**If the subagent did not include a Status field** (malformed report): +- Treat as `BLOCKED`. Re-dispatch with an explicit reminder to use the four-status Report Format. + +When re-dispatching, include the previous report's concerns / blockers so the implementer knows exactly what to fix: + +``` +Continue implementing this task. A previous attempt reported <status> with these concerns: + +<paste concerns> + +Address each concern and re-report. +``` + +### 5. Spec Compliance Review + +After confirming tests pass, dispatch the `spec-reviewer` to independently verify the implementation matches the spec: + +```bash +BASE_SHA=$PRE_TASK_SHA +``` + +Dispatch `spec-reviewer`: + +Use the template at `./spec-reviewer-prompt.md`. Fill placeholders (`{TASK_ID}`, `{BASE_SHA}`, `{HEAD_SHA}`). Spec review is a focused comparison task — the agent default is appropriate; omit `model:` unless the spec is unusually large or ambiguous. + +Handle results: +- `COMPLIANT` → proceed to Step 6 +- `ISSUES (Missing)` → re-dispatch `builder` with specific gaps listed by the spec reviewer. Re-run spec compliance review after. +- `ISSUES (Extra)` → re-dispatch `builder` to remove the extras listed by the spec reviewer. Re-run spec compliance review after. +- `ISSUES (Misunderstood)` → re-dispatch `builder` with clarification from the spec reviewer's findings. Re-run spec compliance review after. +- Circuit breaker: 3 spec-review/fix cycles without resolution → escalate to user. + +> **Docs-only tasks**: Skip this step. The spec-reviewer is designed around code verification (file lists, function signatures, test coverage) and doesn't apply to documentation. For docs-only tasks, the orchestrator verifies formatting/completeness directly: check that all files in `## Files` were created/modified, links resolve, heading hierarchy is correct, code blocks have language tags. + +### 6. Code Quality Review + +Only dispatched after spec compliance passes. Use the `review` skill or dispatch `code-reviewer` directly: + +```bash +HEAD_SHA=$(git rev-parse HEAD) +``` + +Use the template at `../review/reviewer-prompt.md`. Fill placeholders (`{TASK_ID}`, `{BASE_SHA}` = PRE_TASK_SHA recorded earlier, `{HEAD_SHA}` = current HEAD, `{DESIGN_EXCERPT}` from parent epic or "none", `{EVALUATOR_STATUS}` = "active" if evaluator was dispatched, else "not dispatched"). Follow Model Selection above for the dispatch `model:` — sonnet default is appropriate for most reviews. + +**On `{EVALUATOR_STATUS}`:** Decide whether to dispatch the evaluator (step 6.5) BEFORE filling this placeholder. If you plan to run step 6.5 in parallel with step 6, set `{EVALUATOR_STATUS}="active"`. Otherwise set `"not dispatched"`. Step 6.5 has the decision criteria for when to dispatch the evaluator. + +Handle findings: + +| Finding | Action | +|---------|--------| +| **Critical/Important** | Re-dispatch `builder` with fixes. Re-review after. | +| **Minor** | Note in arc comment. Proceed. | +| **Deviation (fix)** | Re-dispatch `builder` to match the design. | +| **Deviation (accept)** | Log as arc comment: "Accepted deviation: \<description\>. Rationale: \<why\>." Proceed. | + +Circuit breaker: 3 review/fix cycles on the same finding → escalate to user. + +> **Docs-only tasks**: Skip code quality review. For substantial documentation changes (developer-facing API docs, architecture docs), optionally dispatch `code-reviewer` for a quality check. + +### 6.5. High-Risk Evaluation (Optional) + +The evaluator is **not dispatched by default**. Dispatch only when: +- Task has a `high-risk` label +- The orchestrator judges the task warrants independent verification (e.g., complex spec with multiple valid interpretations, security-sensitive code, tasks that modify shared contracts) + +When dispatched, use `isolation: "worktree"` and the existing `evaluator` agent. The evaluator can run **in parallel with Step 6** (code quality review) since they examine orthogonal concerns: + +```bash +PARENT=$(arc show <task-id> --json | jq -r '.parent_id // empty') +``` + +Use the template at `./evaluator-prompt.md`. Fill placeholder `{TASK_ID}`. Because evaluation is adversarial verification on high-risk tasks, escalate one tier from the agent default (typically to `opus`) — set `model: "opus"` on the dispatch unless the task is narrow. + +When dispatching alongside the evaluator, update the code quality reviewer's `## Evaluator Status` to `active`. + +Triage evaluator findings: + +| Evaluator verdict | Orchestrator action | +|---|---| +| `PASS` | No action — evaluator confirms the spec intent is satisfied. | +| `CONCERNS` | Read the concerns. Re-dispatch `builder` if the concerns describe substantive behavior gaps. Otherwise note as arc comments and proceed. | +| `FAIL — Spec-Intent Gap` | Re-dispatch `builder` with the evaluator's quoted spec text and the failing behavior description. | +| `FAIL — Missing Behavior` | Re-dispatch `builder` — the spec requires behavior that wasn't built. | +| `FAIL — Edge Case` | Lower-severity. Re-dispatch if the spec clearly implies the edge case; otherwise record as a known limitation. | +| `ERROR — Cannot Test` | The public API is insufficient. Re-dispatch with a request to expose the needed surface. | +| `BLOCKED` | Evaluator itself is blocked. Escalate per the Model Selection rules or involve the human. | + +### 7. Close Task + +```bash +arc close <task-id> -r "Implemented: <summary>" +``` + +### 8. Integration Checkpoint + +After closing 2-3 related tasks, or before switching to a new epic phase, run the full integration test suite: + +```bash +make test-integration +``` + +This catches cross-task regressions that individual implementer gate checks won't — each implementer only validates its own task's scope. Do not wait until all tasks are complete to discover integration failures. + +If integration tests fail: +- Identify which task's changes caused the failure +- Re-dispatch `builder` with the failing test details and the relevant task context +- If the failure spans multiple tasks, invoke the `debug` skill + +### 9. Repeat + +Go to step 1 for the next task. Continue until all tasks in the epic are closed. + +## Handle Implementer Status + +Every `builder` and `doc-writer` dispatch returns one of four terminal statuses. Handle each explicitly: + +| Status | Orchestrator action | +|---|---| +| `DONE` | Proceed to spec review, then code review. | +| `DONE_WITH_CONCERNS` | Read the concerns. If they're about correctness or scope, address before review (re-dispatch or tighten review prompt). If they're observations (file getting large, naming doubt), note them as arc comments on the task and proceed to review — close only after a later dispatch yields a clean `DONE`. | +| `BLOCKED` | Assess the blocker: (1) context problem → provide missing context, re-dispatch same tier; (2) reasoning limit → re-dispatch one tier up per the Model Selection escalation rule; (3) task too large → split and re-plan; (4) plan is wrong → escalate to human. Never retry the same dispatch unchanged. | +| `NEEDS_CONTEXT` | Gather the specific missing information. Re-dispatch with it in the prompt. | + +**Never close a task** whose last report was `BLOCKED`, `NEEDS_CONTEXT`, or `DONE_WITH_CONCERNS` unresolved. Re-dispatch until you have a clean `DONE` — then close. + +## Parallel Dispatch Protocol + +When you have identified a batch of truly independent tasks (see [Dispatch Modes](#dispatch-modes)), switch from the sequential loop to this protocol: + +### P1. Commit Checkpoint + +Before switching to parallel, ensure all sequential work is committed and pushed: + +```bash +git status # Must be clean — no unstaged or uncommitted changes +git log -3 # Verify recent sequential commits are present +git push # Establish a recovery point on the remote +``` + +**Hard gate**: Do NOT proceed if `git status` shows uncommitted changes. + +### P2. Record HEAD Anchor + +```bash +PARALLEL_BASE=$(git rev-parse HEAD) +echo "Parallel base: $PARALLEL_BASE" +``` + +This is the baseline all worktrees will branch from. Record it — you'll need it for verification after merge. + +### P3. Verify Independence + +For each task in the planned parallel batch: + +```bash +arc show <task-id> +``` + +Confirm: +- No `blocks`/`blockedBy` relationships between tasks in this batch +- No overlapping file paths in task descriptions +- Each task has a clearly scoped, non-ambiguous specification + +If any task fails these checks, remove it from the parallel batch and handle it sequentially after. + +### P4. Dispatch in Single Turn + +All parallel Agent tool calls with `isolation: "worktree"` **must happen in the same orchestrator message**.

Merge-Back Verification + +After all parallel agents report back, verify the merge did not lose work: + +```bash +# 1. Check HEAD against the recorded anchor +git log --oneline $PARALLEL_BASE..HEAD # Should show ONLY the parallel agents' commits + +# 2.

If the fallback returns no result, ask the user which review surface the plan was registered on. + +## Granularity Rule + +Each task step is **ONE action, 2-5 minutes**. Assume the implementer has **zero codebase context** and fresh context without codebase familiarity. If a step says "add validation" without showing the code, it's too vague. + +## No Placeholders + +Every step in a task description must contain the actual content an implementer needs. These are **plan failures** — never write them: + +- `"Add appropriate error handling"` / `"add validation"` / `"handle edge cases"` — show the actual code +- `"Write tests for the above"` without test code — include the test code +- `"Similar to Task N"` — repeat the content; the implementer has zero context of other tasks +- Steps that describe what to do without showing how — code blocks required for code steps +- References to types, functions, or methods not defined in any task or already on HEAD +- `"TBD"`, `"TODO"`, `"implement later"`, `"fill in details"` + +Code blocks represent the **intent, structure, and behavior** — not a character-for-character mandate. The implementer follows the code block's signatures, logic, and patterns but adapts naming, error handling, and scaffolding to match project conventions (consistent with the implementer's Gate Check 4: Idiomatic Code Quality). Task-internal Design Contracts remain pseudocode that the implementer adapts to language idioms. The anti-placeholder rule prevents *missing* guidance, not idiomatic adaptation. + +## Workflow + +Add tasks for each step below using `TaskCreate`. If continuing from the brainstorm skill, the brainstorm tasks will already be visible — add the planning tasks alongside them so the user sees the full brainstorm→plan progression. Mark each as `in_progress` when starting and `completed` when done. + +### 1. Read the Design + +You're handed a plan-file path (typically `docs/plans/<file>.md`) by the brainstorm skill. Read line 1 to learn which review surface the plan lives on, then call the matching show command: + +```bash +MARKER=$(head -1 docs/plans/<file>.md) +KIND=$(echo "$MARKER" | grep -oE 'kind=[a-z-]+' | cut -d= -f2) +ID=$(echo "$MARKER" | grep -oE 'id=\S+' | sed 's/id=//' | tr -d '>' | xargs) + +case "$KIND" in + legacy) arc plan show "$ID" ;; + share-local|share-remote) arc share show "$ID" ;; + *) echo "No review marker; reading file directly"; cat docs/plans/<file>.md ;; +esac +``` + +The full content is what you'll break down in the next steps. If the file has no marker (an older design doc), reading the file directly is fine — but warn the user the review-state CLI calls (approve, pull) won't work without a registered review surface, and offer to register it via brainstorm step 6. + +### 2. Identify Shared Contracts (Foundation Task) + +Check the design for **shared contracts** — types, interfaces, config keys, constants, or function signatures referenced by multiple tasks. If the brainstorm design includes a shared contracts section, use it as input. + +If shared contracts exist and parallel execution is likely: + +1. Create a **T0: Foundation** task that establishes all shared contracts +2. Mark all parallelizable tasks as **blocked by T0** +3. T0 runs sequentially before any parallel batch begins + +This ensures parallel agents inherit shared definitions from HEAD rather than inventing them independently. + +**T0 task descriptions must be literal, not prose.** The description should contain: +- **Exact type/interface code** to write to specific files (sourced from the brainstorm design's shared contracts) +- **Inline contract test assertions** to write in each relevant test file, so downstream tasks can verify they are using the correct types +- Steps that say "write this exact code to this exact file" — not vague instructions like "define the memory type" + +Example T0 task description: + +```markdown +## Summary +Establish shared types and contract tests for the memory feature. + +## Files +- Create: `internal/types/memory.go` +- Create: `internal/memory/memory_test.go` + +## Scope Boundary +Do NOT create or modify any files outside the Files section above. + +## Steps +1. Create `internal/types/memory.go` with this exact content: + ```go + package types + + import "time" + + type Memory struct { + ID int64 `json:"id" db:"id"` + Content string `json:"content" db:"content"` + CreatedAt time.Time `json:"created_at" db:"created_at"` + } + ``` +2. Create contract assertions in `internal/memory/memory_test.go`: + ```go + package memory + + import ( + "testing" + "time" + + "yourmodule/internal/types" + ) + + // --- Contract assertions --- + // These verify the design spec. Do NOT modify + // without updating the approved plan. + + func TestMemoryContract(t *testing.T) { + m := types.Memory{} + var _ int64 = m.ID + var _ string = m.Content + var _ time.Time = m.CreatedAt + } + + // --- Behavior tests (added by implementer) --- + ``` +3. Run `go build ./internal/types/...` — confirm it compiles +4. Run `go test ./internal/memory/...` — confirm contract tests pass +5. Commit: `feat(types): add foundation types and contract tests` + +## Test Command +go test ./internal/memory/... + +## Expected Outcome +Shared types compile and contract assertions pass. Parallel tasks can now import these types from HEAD. +``` + +**Skip this step** if the work is purely sequential or no shared contracts were identified. + +### 3. Identify Tasks + +Break the design into self-contained implementation units. Each task should: +- Have a clear, testable outcome +- Be implementable without knowledge of other tasks +- Include exact file paths for all files to create or modify +- Follow a logical dependency order +- **Not overlap in file ownership with other parallelizable tasks** + +When identifying tasks, assign **file ownership** — each file should be owned by exactly one task. If two tasks need to modify the same file, either merge them into one task, serialize them with a dependency, or extract the shared file into the foundation task. + +### 4. Create Epic and Tasks via issue-manager + +**Model tier:** `issue-manager` defaults to `haiku` — the right tier for CLI formatting and bulk issue creation. For this dispatch, omit `model:`. See the Model Selection table in `../build/SKILL.md` for the full guidance. + +**Never run `arc create` directly** — always delegate to the `issue-manager` agent. This keeps bulk CLI output in a disposable subagent context. + +Read the full plan content first using the kind-aware case from step 1 (`arc plan show "$ID"` for legacy, `arc share show "$ID"` for share-local / share-remote). Then build a task manifest that includes: +1. **The epic** — its description will be populated by the agent from the plan file (see below) +2. **All child tasks** with self-contained descriptions + +**Critical**: Do NOT paste or summarize the plan content into the agent prompt. Instead, pass the plan file path and let the agent read it directly. This prevents content loss from summarization. + +You typically already have the plan file path from the brainstorm hand-off. If you only have the ID and need to find the file path, the lookup depends on `kind`: + +```bash +# share-local / share-remote: keyring includes the plan_file mapping +arc share list --json | jq -r '.[] | select(.id=="<id>") | .plan_file' + +# legacy: arc plan show prints "File: <path>" in its metadata header +arc plan show <id> | grep -oE '^File: \S+' | awk '{print $2}' +``` + +The share keyring entries have `{id, kind, url, key_b64url, plan_file, created_at}` — edit tokens are intentionally redacted. Then dispatch the manifest: + +``` +Use the Agent tool with subagent_type="arc:issue-manager": + +Create the following epic and tasks. +After creation, set dependencies and labels as listed. +Return a summary table mapping task names to arc IDs. + +## Epic + +### <epic title> +Type: epic +Plan file: <absolute path to the plan markdown file> + +IMPORTANT: Read the plan file at the path above using the Read tool. Use the COMPLETE +file contents as the epic description. Do NOT summarize, truncate, or paraphrase — +copy the full file content verbatim as the description. + +## Tasks + +### T1: <title> +Type: task +Parent: <epic-id from above> +Description: +<full multi-line self-contained description> + +### T2: <title> +Type: task +Parent: <epic-id from above> +Description: +<full multi-line self-contained description> + +## Dependencies +- T2 blocked by T1 +- T4 blocked by T3 + +## Labels +- T3: docs-only + +## Required Output +| Task | Arc ID | Title | +|------|--------|-------| +| Epic | ... | ... | +| T1 | ... | ... | +``` + +**IMPORTANT**: The epic description MUST contain the complete approved design. The agent reads the plan file directly to avoid any summarization or content loss. The plan file is ephemeral; the epic description is the permanent record. + +For each task, check whether **all** files in its `## Files` section are documentation (`.md`, `.txt`, `README`, `CHANGELOG`, or anything under `docs/`). If so, include it in the `## Labels` section with `docs-only`. Doc-only tasks skip TDD — the `implement` skill routes them to `doc-writer` instead of `builder`. + +### 5. Validate Returned Results + +Before proceeding, verify the agent's output: + +1. **Count check**: The number of returned IDs must match the number of tasks in your manifest +2. **Spot-check**: Run `arc show <id>` on one returned task to confirm it exists and has the correct parent +3. **If mismatch**: Re-dispatch the agent for missing tasks only, or create them manually + +### 6. Append Task Breakdown to Epic Description + +The epic was created in step 4 with the full design content. Now append the task breakdown table (with actual arc IDs from step 5) to the epic's description: + +```bash +arc update <epic-id> --stdin <<'EOF' +<existing epic description — the full design content from step 4> + +--- + +## Implementation Tasks + +<task breakdown table with arc IDs, titles, statuses, and dependency info> +EOF +``` + +**IMPORTANT**: Preserve the full design content already in the description — do not replace it with a summary. The epic description is the permanent record of the design. Only append the task breakdown table at the end. + +### 6.5. Self-Review + +After writing all tasks, review the plan against the design before proceeding: + +1. **Spec coverage:** Skim each section/requirement in the design. Can you point to a task that implements it? If a gap exists, add the task. +2. **Placeholder scan:** Search all task descriptions for red flags from the No Placeholders list. Fix them. +3. **Type consistency:** Do the types, method signatures, and property names used in later tasks match what was defined in earlier tasks? A function called `clearLayers()` in T1 but `clearFullLayers()` in T3 is a bug. +4. **Step completeness:** Every code step has a code block. Every command step has the exact command and expected output. No exceptions. + +Fix issues inline. No need to re-review — just fix and move on. + +### 7. Choose Execution Path + +**Use the AskUserQuestion tool** to let the user choose: + +``` +Question: "Epic and tasks created. How should we proceed with implementation?" +Options: + - "Start implementing now" (invoke /arc:build in this session — subagents handle TDD per task) + - "Implement in a new session" (provides the exact prompt to use) + - "Done for now" (tasks are tracked in arc — implement manually or later) +``` + +After the user chooses: + +**Start implementing now**: Invoke the `implement` skill immediately with the epic ID. + +**Implement in a new session**: Output the exact command for the user to copy-paste: +``` +Run this in a new Claude Code session: + + /arc:build <epic-id> + +``` +Replace `<epic-id>` with the actual epic ID. + +**Done for now**: Confirm the epic and tasks are saved in arc. The user can run `/arc:build <epic-id>` whenever they're ready. + +## Task Description Format + +Each task's `--description` must be **self-contained** (~3-5k tokens). The task description IS the implementation context — the implementer loads `arc show <task-id>` and nothing else. + +Include in every task description: + +``` +## Files +- Create: `path/to/new_file.go` +- Modify: `path/to/existing_file.go` +- Test: `path/to/file_test.go` + +## Scope Boundary +Do NOT create or modify any files outside the Files section above. +If you need a type, interface, or constant that doesn't exist, do NOT create it — +the foundation task or a prior task is responsible for shared definitions. + +## Design Contracts + +### Shared (use verbatim — defined in T0: Foundation) +```go +type Memory struct { + ID int64 `json:"id" db:"id"` + Content string `json:"content" db:"content"` + CreatedAt time.Time `json:"created_at" db:"created_at"` +} +``` + +### Task-internal +- `FeedbackRequest { memory_id: i64, rating: i8, comment: String? }` +- `MemoryStore.InsertMemory(content string) → (int64, error)` + +## Steps +1. Write failing test for <specific behavior> in `path/to/file_test.go` +2. Run `go test ./path/to/...` — confirm it fails with <expected error> +3. Implement <specific function> in `path/to/new_file.go`: + ```go + func specificFunction(arg Type) (Result, error) { + // exact implementation code — not prose descriptions + } + ``` +4. Run `go test ./path/to/...` — confirm it passes +5. Commit: `feat(module): add <feature>` + +## Test Command +go test ./path/to/... + +## Expected Outcome +<what should work when this task is done> +``` + +**Hard rule:** Every code step requires a code block. Every command step requires the exact command and expected output. Steps without these are plan failures — see the No Placeholders section above. + +### Design Contracts guidance + +Include a `## Design Contracts` section in every non-T0 task description, placed after `## Scope Boundary` and before `## Steps`. This section has two subsections: + +- **Shared (use verbatim)**: Exact type definitions copied from the T0 foundation task. The subagent MUST use these types exactly as written — same field names, same tags, same package. These are the canonical contracts established by T0 and committed to HEAD. +- **Task-internal**: Pseudocode descriptions of types and signatures that are private to this task. The subagent adapts these to language idioms (naming conventions, error handling patterns, etc.) as appropriate. + +If a type the subagent needs is not listed in Design Contracts and is not already on HEAD from T0, the subagent must NOT create it. This rule complements the Scope Boundary section — Scope Boundary restricts file ownership, Design Contracts restricts type ownership. + +For `docs-only` tasks, omit `## Test Command` and use `## Verification` instead: + +``` +## Verification +- All internal links resolve to existing files +- Heading hierarchy has no skipped levels +- Code blocks have language tags +``` + +## Rules + +- Never reference external docs or the full plan in task descriptions — everything needed is in the description +- Design documents live in `docs/plans/` and are registered via one of `arc plan create` (legacy), `arc share create` (encrypted local default), or `arc share create … --remote` (encrypted remote).
