orc

"Zug zug."

Let the orcs do the work.

A personal Claude Code plugin for the senior-developer day — plan → debug → verify → ship — with curated skills, composite commands, and a senior-dev agent that writes the code while you mind the gates.

What it does

orc is a personal-workflow plugin: 54 curated skills, 19 composite slash commands, 10 specialist subagents, and 4 hook scripts that quietly enforce discipline (no commits to main, no AI-attribution trailers in commits/PRs, dependency pre-flight check, skill catalog injected at every session start). One umbrella command — /orc:flow — drives the full feature lifecycle from "I want to do X" to "PR merged" with orc-implementer writing the code slice-by-slice in between.

It exists for one reason: every time a senior developer sits down to work, they should already know how the next hour goes — write the plan, watch the test fail, fix the cause (not the symptom), verify with evidence, ship the PR. orc encodes that loop.

Mental model

orc maps the senior IC / tech-lead / architect day to a small set of composite commands. Most work fits this loop:

flowchart LR
    plan["/orc:plan"] --> start["/orc:start"] --> impl["implement"] --> qa["/orc:qa"] --> ship["/orc:ship"] --> cleanup["/orc:cleanup"]
    cleanup -.->|"interrupted? /orc:resume"| plan
    cleanup -.->|"need status? /orc:status"| plan

Loading

Outside the loop — reach for these directly when the situation isn't a fresh feature pipeline:

Situation	Command
Debugging a known bug	/orc:debug
Reviewing someone else's PR	/orc:code-review
Responding to your PR's review comments	/orc:address
Authoring a Product Requirements Document	/orc:prd
Authoring a Technical Requirements Document	/orc:trd
Locking in an architectural decision	/orc:adr
Proposing a system design before code	/orc:rfc
Writing an incident postmortem	/orc:postmortem
Bootstrapping a new package/service	/orc:scaffold
Parallel-dispatching N independent tasks	/orc:fan-out
Filing/linking a Jira ticket from the terminal	/orc:jira

Or skip the per-phase invocations and use /orc:flow to drive the whole loop — gates at every phase, autonomous implementation in between via orc-implementer.

Common scenarios — pick one

You have ...	Read
A whole feature/bug to drive end-to-end	examples/00 — End-to-end with /orc:flow
A reproducible bug or failing test	examples/01 — Fixing a bug
Just had a production incident	examples/02 — Writing a postmortem
A new feature to ship	examples/03 — Adding a new feature
A new package/service or doc gap	examples/04 — Writing documentation
A PRD from PM	examples/05 — Handling a PRD
Someone else's open PR	examples/06 — Reviewing someone's PR
Reviewer comments on your PR	examples/07 — Responding to PR feedback
A non-trivial architectural decision	examples/08 — Writing an ADR
A multi-week design needing critique	examples/09 — Writing an RFC
A web change ready to ship	examples/10 — Web QA before shipping
Multiple teammates' PRs to review (or any N independent tasks)	examples/11 — Multi-PR review with /orc:fan-out
A Jira ticket to link to a session and close on PR merge	examples/12 — Linking a Jira ticket and shipping with Resolves <KEY>

Each example follows the same shape — Scenario → Flow → Walk-through → Artifacts → Done when → Variants → Iron rules in play — so you can scan to the relevant section.

Install

Via the marketplace (recommended for friends / clean machines)

orc is published as a single-plugin marketplace at this repo. Inside Claude Code:

/plugin marketplace add HigorAlves/orc
/plugin install orc@orc

The first command registers https://github.com/HigorAlves/orc as a marketplace named orc; the second installs the orc plugin from it. Updates pull with /plugin update orc@orc.

To pin a specific commit/tag, use the longhand source form in ~/.claude/settings.json:

{
  "extraKnownMarketplaces": {
    "orc": {
      "source": {
        "source": "url",
        "url": "https://github.com/HigorAlves/orc.git",
        "ref": "v0.1.0"
      }
    }
  },
  "enabledPlugins": { "orc@orc": true }
}

The plugin uses an HTTPS clone URL explicitly so installation works on machines without GitHub SSH keys configured. If you have git config --global url.git@github.com:.insteadOf https://github.com/ set, that rewrite will hit this URL too — temporarily disable the rewrite, or use the local plugin-dir flow below.

Via local plugin-dir (recommended for development on this repo)

claude --plugin-dir /Users/higoralves/Developer/system/orc

Reload after edits without restarting:

Requirements

orc's SessionStart pre-flight (hooks/scripts/session-start-tool-check.sh) verifies these CLI tools are installed and surfaces a ⚠ Tool check ───── warning if anything's missing.

Tool	Tier	Used by
git	required	every command
jq	required	hook scripts (parse Bash tool input)
gh	recommended	/orc:code-review, /orc:address, /orc:ship, /orc:postmortem
agent-browser	recommended	/orc:qa (web mode — browser-driven QA evidence)
acli	recommended	/orc:jira, /orc:plan|start|debug|flow (Jira ticket linking), /orc:prd|trd (--from-jira <KEY> seeding)

Suppress the check on machines where missing tools are intentional:

export ORC_SKIP_TOOL_CHECK=1

Environment variables

Variable	Effect
ORC_SKIP_TOOL_CHECK=1	Suppress the SessionStart ⚠ Tool check block when a recommended dependency is intentionally missing.
ORC_ALLOW_PROTECTED=1	Allow git commit / git push on main / master / develop. The PreToolUse hook refuses by default; this flag opts in for the rare scaffold/hot-fix case.
ORC_ALLOW_AI_ATTRIBUTION=1	Allow Co-Authored-By: Claude, 🤖 Generated with Claude Code, or other AI-attribution trailers in commit messages and PR bodies. The PreToolUse hook refuses them by default (iron rule #5). Set only with explicit user consent.
ORC_JIRA_PR_KEYWORD	PR-body trailer keyword used by /orc:ship when the active session has a bound jiraTicket. Defaults to Resolves. Set to Closes or Fixes for orgs whose Jira/GitHub integration uses a different keyword.

Day-one command catalog

Command	Purpose
/orc:flow	Recommended entry point. Drives the full lifecycle (plan → start → implement → QA → ship → address → cleanup) with an AskUserQuestion gate at every phase. Resumable from any phase.
/orc:plan	Plan a feature/refactor; writes a TDD-shaped plan to .orc/<branch>/files/
/orc:start	Worktree + plan + first failing test (TDD red light)
/orc:debug	Root-cause investigation, then fix with TDD; never papers over
/orc:qa	Pre-PR quality gate; for web changes, full browser QA with screenshots/video/steps
/orc:code-review	Review someone else's open PR; terse, signal-only output
/orc:address	Answer reviewer comments on YOUR PR; parallel code-fixer + reply-drafter
/orc:ship	Finalize and open the PR
/orc:fan-out	Dispatch independent tasks in parallel sub-sessions
/orc:scaffold	Bootstrap a new package/service with proper README + Diátaxis docs
/orc:resume	Pick up an interrupted multi-phase command from its checkpoint
/orc:status	Show all active .orc/ workspaces
/orc:adr	Author an Architecture Decision Record (docs/adr/NNNN-*.md)
/orc:rfc	Author a system-design RFC pre-implementation (docs/rfcs/NNNN-*.md)
/orc:prd	Author a Product Requirements Document (docs/prds/NNNN-*.md); supports --interview and --from-jira <KEY>
/orc:trd	Author a Technical Requirements Document (docs/trds/NNNN-*.md); supports --from-prd NNNN
/orc:jira	Manage Jira tickets via acli (create/subtask/link/view/search/transition); bind/unbind a ticket key to the current .orc/ session
/orc:postmortem	Author a blameless incident postmortem; files P0 action items as tracker issues
/orc:cleanup	Remove .orc/ state, worktree, and (if merged) branch for completed sessions

Plus the meta skill using-orc (auto-injected at SessionStart, encodes iron rules). Total: 54 skills.

Insight blocks

When orc is writing or modifying code, it surfaces 2–3 short, codebase-specific notes inline using:

`★ Insight ─────────────────────────────────────`
[2–3 short, codebase-specific insights]
`─────────────────────────────────────────────────`

This is baked into skills/using-orc/SKILL.md and injected at every SessionStart, so orc is self-sufficient — no separate explanatory-output-style plugin required.

Iron rules (enforced by hooks + the using-orc skill)

1. No commits to main/master/develop without ORC_ALLOW_PROTECTED=1.
2. No code without a failing test first.
3. No claims without verification (run the command, read the output).
4. No fixes without a found root cause.
5. No AI attribution in code, commits, or PRs.
6. No multi-phase work without .orc/ checkpoints.

Web QA evidence is a hard rule

Any web-surface change going through /orc:qa MUST produce, in .orc/<branch>/files/qa/:

• screenshot-NN-<step>.png per visible step (annotated via agent-browser screenshot --annotate)
• snapshot-final.txt — accessibility tree from agent-browser snapshot
• console.log — captured browser console (errors flagged)
• network.har — network traffic from agent-browser network har start/stop
• steps.md — narrated golden path + edge cases

Bonus (optional): trace.json, react-renders.json, vitals.json, or an OS-recorded video.mov for animated changes. agent-browser does not record video natively.

Without the required artifacts, "QA passed" is not an accepted claim. The orc-qa-validator agent — driven by the vercel-labs/agent-browser CLI via the orc:agent-browser skill — produces them.
