Fits the existing + `executeCommand()` pattern perfectly. + - ❌ Cons: ~20ms subprocess overhead per invocation. Must read file from disk (already true + — tools operate on the workspace directory). + +2. **Tree-sitter Java bindings** — Embed Tree-sitter grammars via JNI/JNA. + - ✅ Pros: In-process, no subprocess overhead. Can parse in-memory strings. + - ❌ Cons: Per-language grammar JARs/native libs (2-5MB each × 10+ languages). JNI stability + across architectures. Must implement extraction logic per language. Massive dependency bloat + compared to a ~2MB ctags binary. + +**Decision** +We choose **Universal Ctags** because it fits the existing `executeCommand()` tool execution +pattern, has zero Java dependency footprint, and supports all languages with a single tool. + +**Consequences** +- Docker image grows by ~2 MB. +- Tools are limited to files-on-disk (workspace directory), which is already the model for all + context tools. +- Ctags JSON format is stable but should be guarded with error handling for unknown languages. + +--- + +## Review Checklist (before implementation) + +- [ ] No manual getters/setters — Lombok used everywhere +- [ ] No raw `@Autowired` field injection — constructor injection only +- [ ] DTOs at API boundary — `formatCtagsDependencies()` returns a JSON `String`; `formatCtagsSignatures()` returns a Markdown `String`.

This is +intentional: operators who maintain custom configurations should control +exactly which tools their bots can invoke. + +For each custom tool configuration you maintain: + +1. Open **System settings → Tool configurations**. +2. Click the configuration name to open its editor. +3.

Total image size increase is negligible. + +--- + +## 4. Database migration + +Flyway migration **`V29`** adds two rows to the default tool +configuration's selection table. It is idempotent — running the +migration multiple times (e.g., after a `flyway repair`) is safe. + +```sql +INSERT INTO bot_tool_selections (configuration_id, tool_name, tool_kind) +SELECT c.id, v.tool_name, v.tool_kind +FROM bot_tool_configurations c +CROSS JOIN (VALUES + ('ctags-signatures', 'CONTEXT'), + ('ctags-deps', 'CONTEXT') +) AS v(tool_name, tool_kind) +WHERE c.default_entry = TRUE + AND NOT EXISTS ( + SELECT 1 FROM bot_tool_selections s + WHERE s.configuration_id = c.id AND s.tool_name = v.tool_name + ); +``` + +**No other tables, columns, or constraints are modified.** The migration +only inserts rows; it never deletes or alters existing data. + +**Rollback.** If you roll back the application binary after V29 has +executed, the two new rows will remain in `bot_tool_selections`. The +1.13.x application's `ToolCatalog` does not register these tool names, +so they will appear as `ToolKind.UNKNOWN` and be rejected by the +whitelist enforcement in `AgentToolRouter`. No runtime errors occur, +but the rows are harmless dead data. You can delete them manually if +desired: + +```sql +DELETE FROM bot_tool_selections WHERE tool_name IN ('ctags-signatures', 'ctags-deps'); +``` + +--- + +## 5. Environment variable and config changes + +**No new application properties are required.** The new tools use the +existing `agent.validation.tool-timeout-seconds` timeout when invoking +ctags. No new `application.properties` or `application.yml` keys are +introduced. + +--- + +## 6. Behaviour notes + +- **Tools are opt-in per bot.** A bot only has access to the new tools + if its assigned tool configuration includes them. Bots using the + default configuration get them automatically; bots with custom + configurations need manual activation. +- **ctags must be on PATH.** The runtime image includes `universal-ctags` + at `/usr/bin/ctags`. If ctags is missing, the tools return a non-zero + exit code error to the AI agent (same pattern as `git-log` and + `git-blame` when `git` is unavailable). +- **Silent tools.** Like all CONTEXT tools, `ctags-signatures` and + `ctags-deps` never appear in public PR/issue comments. Their output is + visible only to the AI agent. +- **No UI changes.** The tools appear in the System Settings → Tool + Configurations editor under the CONTEXT section, alongside the existing + `rg`, `find`, `cat`, `tree`, etc. No new UI pages or forms are added. + +--- + +## 7.

Mitigation: the agent loop budget is already capped by `maxToolRounds` (default 12, user-configurable), and the user explicitly asked for the agentic approach. +- **No conversation memory across clarifications:** Unlike `CodeReviewService` which persists a `ReviewSession` across turns, the agentic clarification is stateless — each `@bot clarify` starts fresh. Mitigation: this is consistent with how `@bot rerun-tests` works (each invocation is independent). If multi-turn memory is needed later, it can be added as a separate feature. diff --git a/docker-compose.yml b/docker-compose.yml index c3bfbb0e..adddad99 100644 --- a/docker-compose.yml +++ b/docker-compose.yml @@ -12,7 +12,7 @@ services: DATABASE_PASSWORD: ${DATABASE_PASSWORD:-giteabot} # Encryption key for API keys stored in database (optional, but recommended for production) APP_ENCRYPTION_KEY: ${APP_ENCRYPTION_KEY:-} - APP_PUBLIC_URL: ${APP_PUBLIC_URL:-http://localhost:8080} + APP_PUBLIC_URL: ${APP_PUBLIC_URL:-http://167.235.231.84:8080} # Optional agent prompt context limits; reduce these for small local LLM context windows AGENT_CONTEXT_MAX_TREE_FILES: ${AGENT_CONTEXT_MAX_TREE_FILES:-500} AGENT_CONTEXT_MAX_ISSUE_COMMENTS: ${AGENT_CONTEXT_MAX_ISSUE_COMMENTS:-50} diff --git a/src/main/java/org/remus/giteabot/admin/BotWebhookService.java b/src/main/java/org/remus/giteabot/admin/BotWebhookService.java index 86218599..b1cd867d 100644 --- a/src/main/java/org/remus/giteabot/admin/BotWebhookService.java +++ b/src/main/java/org/remus/giteabot/admin/BotWebhookService.java @@ -18,6 +18,7 @@ import org.remus.giteabot.prworkflow.e2e.E2ETestWorkflow; import org.remus.giteabot.prworkflow.e2e.E2eTestPrCloseHandler; import org.remus.giteabot.prworkflow.e2e.E2eTestSlashCommandHandler; +import org.remus.giteabot.prworkflow.agentreview.AgentReviewSlashCommandHandler; import org.remus.giteabot.prworkflow.review.ReviewWorkflow; import org.remus.giteabot.prworkflow.unittest.UnitTestSlashCommandHandler; import org.remus.giteabot.prworkflow.unittest.UnitTestWorkflow; @@ -54,6 +55,7 @@ public class BotWebhookService { private final E2eTestPrCloseHandler e2eTestPrCloseHandler; private final E2eTestSlashCommandHandler e2eTestSlashCommandHandler; private final UnitTestSlashCommandHandler unitTestSlashCommandHandler; + private final AgentReviewSlashCommandHandler agentReviewSlashCommandHandler; private final WorkflowSelectionService workflowSelectionService; private final AgentServiceFactory agentServiceFactory; @@ -73,6 +75,7 @@ public BotWebhookService(AiClientFactory aiClientFactory, E2eTestPrCloseHandler e2eTestPrCloseHandler, E2eTestSlashCommandHandler e2eTestSlashCommandHandler, UnitTestSlashCommandHandler unitTestSlashCommandHandler, + AgentReviewSlashCommandHandler agentReviewSlashCommandHandler, WorkflowSelectionService workflowSelectionService) { this.giteaClientFactory = giteaClientFactory; this.agentSessionService = agentSessionService; @@ -81,6 +84,7 @@ public BotWebhookService(AiClientFactory aiClientFactory, this.e2eTestPrCloseHandler = e2eTestPrCloseHandler; this.e2eTestSlashCommandHandler = e2eTestSlashCommandHandler; this.unitTestSlashCommandHandler = unitTestSlashCommandHandler; + this.agentReviewSlashCommandHandler = agentReviewSlashCommandHandler; this.workflowSelectionService = workflowSelectionService; this.agentServiceFactory = new AgentServiceFactory(aiClientFactory, giteaClientFactory, promptService, agentConfig, agentSessionService, toolExecutionService, toolCatalog, @@ -147,6 +151,9 @@ public void handleBotCommand(Bot bot, WebhookPayload payload) { if (unitTestSlashCommandHandler.tryHandle(bot, payload)) { return; } + if (agentReviewSlashCommandHandler.tryHandle(bot, payload)) { + return; + } if (isWorkflowEnabled(bot, ReviewWorkflow.KEY)) { // Route through the PrWorkflow orchestrator for uniform lifecycle management. var hints = Map.of(ReviewWorkflow.HINT_REVIEW_ACTION, ReviewWorkflow.ACTION_BOT_COMMAND); @@ -210,6 +217,9 @@ public void handlePrComment(Bot bot, WebhookPayload payload) { if (unitTestSlashCommandHandler.tryHandle(bot, payload)) { return; } + if (agentReviewSlashCommandHandler.tryHandle(bot, payload)) { + return; + } if (isWorkflowEnabled(bot, ReviewWorkflow.KEY)) { // Route through the PrWorkflow orchestrator for uniform lifecycle management. var hints = Map.of(ReviewWorkflow.HINT_REVIEW_ACTION, ReviewWorkflow.ACTION_BOT_COMMAND); diff --git a/src/main/java/org/remus/giteabot/agent/tools/ToolCatalog.java b/src/main/java/org/remus/giteabot/agent/tools/ToolCatalog.java index 57ee7a61..a0063089 100644 --- a/src/main/java/org/remus/giteabot/agent/tools/ToolCatalog.java +++ b/src/main/java/org/remus/giteabot/agent/tools/ToolCatalog.java @@ -97,7 +97,9 @@ private record Entry(String name, ToolKind kind, Set roles, "Find files by glob pattern.

When a bot has only `"agentic-review"` enabled, the mention falls through to "unrecognized command." - -In `handleInlineComment` and `handleReviewSubmitted`, the early-return guards also only check `ReviewWorkflow.KEY`. - -### Root Cause 2 — No slash-command handler exists for the agentic review workflow - -The E2E test workflow and unit-test workflow each have their own `SlashCommandHandler` beans (`E2eTestSlashCommandHandler`, `UnitTestSlashCommandHandler`) that are injected into `BotWebhookService` and given first crack at any @mention in `handlePrComment`/`handleBotCommand`. These handlers: - -- Match a regex pattern (e.g. `@bot rerun-tests`, `@bot regenerate-tests `) -- Check that their workflow is enabled on the bot's configuration -- Add an 👀 eyes reaction for acknowledgment -- Hydrate PR details if missing from the webhook payload -- Dispatch the workflow via `PrWorkflowOrchestrator.run(bot, payload, workflowKey, hints)` - -The agentic review workflow has **no such handler**. And even if it did, `AgentReviewWorkflow.run()` does not check for hint-driven modes — it always runs the full review. - -### Root Cause 3 — `AgentReviewWorkflow` has no conversational mode - -Unlike `ReviewWorkflow` which uses a hint-based switch (`ACTION_REVIEW`, `ACTION_BOT_COMMAND`, `ACTION_INLINE_COMMAND`, `ACTION_REVIEW_SUBMITTED`, `ACTION_PR_CLOSED`), `AgentReviewWorkflow.run()` has a single code path: clone workspace, run agent loop, post review comment. There's no "answer a clarification question" variant. - ---- - -## Design Decision - -**Follow the established SlashCommandHandler pattern** — create an `AgentReviewSlashCommandHandler` that catches `@bot clarify ` (and any freeform `@bot ` as a fallback when no other handler matches), then re-triggers `AgentReviewWorkflow` in a new "conversational answer" mode driven by a hint. - -**Rationale:** -- The `E2eTestSlashCommandHandler` / `UnitTestSlashCommandHandler` pattern is proven, consistent, and well-tested. -- The user explicitly wants consistency with how other agentic workflows handle interactions. -- It avoids coupling the agentic review to the simple `CodeReviewService` (which was the previous plan's approach, rejected by the user). -- Each workflow owns its own interaction surface — the handler is co-located in the same package. - -**The slash command pattern:** -``` -User writes: @bot clarify Why did you flag the null check in AuthFilter? -Handler matches: "^@\S+\s+clarify\b\s*(.*)$" -Handler checks: is agentic-review enabled on this bot? -Handler: adds 👀 reaction -Handler: dispatches orchestrator.run(bot, payload, "agentic-review", hints={"agentic-review.clarification": "Why did you flag..."}) -Workflow: sees hint → runs conversational agent loop → posts answer as PR comment -``` - -**Fallback behavior:** When the bot has only `agentic-review` enabled and the user writes `@bot ` that doesn't match `clarify` (or any other handler), we still need to respond. The simplest path: the `AgentReviewSlashCommandHandler` acts as a catch-all for any `@bot` message that no other handler consumed, interpreting it as a clarification request. - -**Alternative considered and rejected:** Route conversational interactions through the simple `ReviewWorkflow`. Rejected because the user explicitly wants consistency with the agentic handler pattern, not delegation to the non-agentic path. - ---- - -## Implementation Plan - -### Goal -Add a `@bot clarify ` slash command to the agentic review workflow, following the exact pattern established by `E2eTestSlashCommandHandler` and `UnitTestSlashCommandHandler`, so users can have follow-up conversations after an agentic review. - -### Components to create / modify - -- [ ] **New: `AgentReviewSlashCommandHandler`** — detects `@bot clarify `, dispatches to `AgentReviewWorkflow` with a hint -- [ ] **Modify: `PrWorkflowContext`** — add `HINT_AGENTIC_REVIEW_CLARIFICATION` constant -- [ ] **Modify: `AgentReviewWorkflow`** — check for the clarification hint, run conversational mode when present -- [ ] **Modify: `AgentReviewService`** — add `answerClarification(WebhookPayload, String userQuestion)` method that runs a conversational agent loop -- [ ] **Modify: `BotWebhookService`** — inject `AgentReviewSlashCommandHandler`, give it a `tryHandle()` slot in both `handlePrComment()` and `handleBotCommand()` - -### Sequence - -#### Step 1: Add hint constant to `PrWorkflowContext` - -``` -File: src/main/java/org/remus/giteabot/prworkflow/PrWorkflowContext.java -``` - -Add: -```java -/** Threaded by AgentReviewSlashCommandHandler for the @bot clarify command. */ -public static final String HINT_AGENTIC_REVIEW_CLARIFICATION = "agentic-review.clarification"; -``` - -This follows the naming convention of `HINT_E2E_FEEDBACK` and `HINT_RERUN_ONLY`. - -#### Step 2: Add `answerClarification()` to `AgentReviewService` - -``` -File: src/main/java/org/remus/giteabot/prworkflow/agentreview/AgentReviewService.java -``` - -New method: -```java -/** - * Answers a clarification question about a previously-reviewed PR by running - * a conversational agent loop. - * - * @param payload the webhook payload (for PR identity) - * @param userQuestion the user's follow-up question - * @return true when a non-empty answer was produced and posted - */ -public boolean answerClarification(WebhookPayload payload, String userQuestion) { - // Same workspace clone as reviewPullRequest - // Build user message: "The user asks a follow-up question about the PR you reviewed earlier:\n\n{question}\n\nPR context:\nTitle: {title}\nDiff:\n{diff}\n\nUse your read-only tools to inspect the code and answer the question." - // Run the agent loop (same ReviewAgentStrategy — it already works for read-only exploration) - // Post the answer as a regular PR comment (not a review comment): "## 🤖 Follow-up\n\n{answer}" - // Clean up workspace -} -``` - -Key differences from `reviewPullRequest`: -- System prompt mentions this is a follow-up clarification, not a full review -- User message frames the question specifically -- Output is posted via `postPullRequestComment` (not `postReviewComment`) so it appears as a regular thread comment -- No `formatReview` wrapper — uses a lighter `## 🤖 Follow-up` header - -#### Step 3: Add conversational mode to `AgentReviewWorkflow.run()` - -``` -File: src/main/java/org/remus/giteabot/prworkflow/agentreview/AgentReviewWorkflow.java -``` - -In `run()`, before the current logic, check for the clarification hint: - -```java -@Override -public WorkflowResult run(PrWorkflowContext context) { - Bot bot = context.bot(); - WebhookPayload payload = context.payload(); - - // Check for conversational clarification first - String clarification = context.hint(PrWorkflowContext.HINT_AGENTIC_REVIEW_CLARIFICATION); - if (clarification != null && !clarification.isBlank()) { - return doClarification(context, clarification); - } - - // ... existing review logic unchanged ... -} - -private WorkflowResult doClarification(PrWorkflowContext context, String userQuestion) { - Bot bot = context.bot(); - // Resolve params (only maxToolRounds is needed) - // ... - context.requireActive("before running agentic clarification"); - boolean answered = serviceFactory.create(bot) - .answerClarification(context.payload(), userQuestion); - context.appendStep("agentic-clarification", - answered ?

A fallback catch-all is included for any `@bot ` when no other handler consumed it, but only when agentic-review is enabled — this prevents a bot configured for E2E tests from accidentally routing `@bot rerun-tests` to the agentic review. -- The clarification response is posted as a regular PR comment (via `postPullRequestComment`), not a review comment — it's a conversational reply, not a formal review. -- `AgentReviewService.answerClarification()` reuses the existing `ReviewAgentStrategy` and agent loop infrastructure. No new strategy class needed. - -### Verification - -1. **Unit tests** (`AgentReviewSlashCommandHandlerTest`) cover pattern matching, dispatch, and guard conditions. -2. **Manual integration test:** - - Configure a bot with only the "Agentic PR Review" workflow - - Open a PR → agentic review is posted - - Comment `@bot clarify Why did you flag the null check in AuthFilter?` - - Expected: 👀 reaction appears immediately - - Expected: bot clones workspace, inspects code, posts a conversational answer as a PR comment -3. **Manual integration test (fallback):** - - Same bot, comment `@bot what about the error handling in line 42?` - - Expected: bot still responds (fallback catch-all matches) - -### Risks - -- **Token cost:** Each clarification fires a full agent loop (clone + LLM + tool calls). For a conversational answer this is heavyweight compared to the simple `CodeReviewService` chat. Mitigation: the agent loop budget is already capped by `maxToolRounds` (default 12, user-configurable), and the user explicitly asked for the agentic approach. -- **No conversation memory across clarifications:** Unlike `CodeReviewService` which persists a `ReviewSession` across turns, the agentic clarification is stateless — each `@bot clarify` starts fresh. Mitigation: this is consistent with how `@bot rerun-tests` works (each invocation is independent). If multi-turn memory is needed later, it can be added as a separate feature. diff --git a/src/test/java/org/remus/giteabot/admin/BotWebhookServiceTest.java b/src/test/java/org/remus/giteabot/admin/BotWebhookServiceTest.java index 76582b76..70fb65e0 100644 --- a/src/test/java/org/remus/giteabot/admin/BotWebhookServiceTest.java +++ b/src/test/java/org/remus/giteabot/admin/BotWebhookServiceTest.java @@ -28,9 +28,16 @@ import org.springframework.dao.DataIntegrityViolationException;
