The Review Comment Handler is a **standalone module** that runs alongside the CI monitor — it is architecturally independent and has no dependencies on other modules (auto-fix, retest, etc.). + +This module reads reviewer comments on PRs, determines which need attention, and invokes Claude Code CLI (agentic mode) to either make code changes or post explanations. + +### Prior Art: `openshift-eng/ai-helpers` address-review-pr + +Adapted from the production-tested [`address-review-pr`](https://github.com/openshift-eng/ai-helpers/tree/main/plugins/openshift-developer/skills/address-review-pr) skill: + +- **Two-pass comment fetching** — metadata first, full body only for kept items +- **5-level categorization** — ACTION_INSTRUCTION > BLOCKING > CHANGE_REQUEST > QUESTION > SUGGESTION +- **`check_replied.py`** — stdlib-only Python script (~350 lines) using `gh` CLI subprocess for duplicate reply detection via GraphQL + REST.

Code change requests get a commit + push + reply. Questions get an explanation reply. + +**Developer experience:** +1. Developer opens PR -> Prow CI runs (including `oape-ci-monitor`) +2. Reviewers leave comments -> next `oape-ci-monitor` run picks them up +3. Bot pushes fix commits for actionable feedback + replies to each thread +4. Bot posts explanations for questions +5. Developer returns to see mechanical feedback already handled + +--- + +## Architecture Decisions + +### Decision 1: Separate Prow step (not inside `dispatch.sh`) + +**Problem:** `dispatch.sh` exits early when `OVERALL_STATUS == "passed"` (line 67-69) or `TRIGGER_COUNT == 0` (line 72-75). Review comments exist independently of CI status — a PR can have all-green CI but pending review comments. + +**Decision:** Add `review-handler.sh` as a separate command in `prow-ci-operator-config.yaml`, after `dispatch.sh`: + +```yaml +/app/scripts/ci-monitor/monitor.sh +/app/scripts/ci-monitor/dispatch.sh +/app/scripts/pr-agent/review-handler.sh --pr-url "$PR_URL" +``` + +This guarantees the review handler runs regardless of CI status. The `entrypoint.sh` integration is a secondary path for on-demand/periodic runs. + +**Rejected alternative:** Restructuring `dispatch.sh` to not exit early — couples review handling to CI failure processing unnecessarily. + +### Decision 2: Claude in `--print` mode with tool use + +The review handler invokes `claude -p` (print mode) with `--permission-mode bypassPermissions` and `--allowedTools`. In print mode, Claude still has full tool access — it autonomously: +- Reads files, makes edits +- Runs `go build ./...` and `go vet ./...` +- Commits via `git commit` +- Posts replies via `gh api` + +Print mode is preferred for CI because it processes the prompt, executes tools, and exits deterministically — no interactive session. Tool restrictions via `--allowedTools` prevent destructive operations (push is excluded — all commits are batched and pushed by the outer script). A `timeout 300` wrapper caps each invocation at 5 minutes. + +### Decision 3: Claude CLI prerequisite — graceful degradation + +The handler checks for `claude --version` at startup and exits 0 with a warning if unavailable. This means it can be deployed before Claude CLI is installed in the container image. + +### Decision 4: One Claude invocation per thread + +Each review thread gets its own `claude` invocation with `timeout 300`. Per-thread is simpler, more auditable, and prevents one complex thread from consuming the entire budget. + +### Decision 5: `check_replied.py` as sole dedup mechanism + +Use `check_replied.py` as the **only** duplicate prevention mechanism. It's API-based, works across runs, and requires no state persistence. + +**Rejected alternative:** Dual dedup with `addressed[]` state arrays — creates state loading gaps between code paths (Prow step vs `entrypoint.sh`), batched-vs-per-thread update bugs, and dual-mechanism confusion. + +### Decision 6: Let Claude categorize (no bash keyword matching) + +Pass the raw comment to Claude with the SKILL.md guidance. Claude categorizes using the 5-level system described in the skill. Bash only determines: "has this thread been replied to?" (via `check_replied.py`) and "is this a bot comment?" (via `is_skip_user()`). + +**Rejected alternative:** 5-level categorization in bash via keyword regex (~50-100 lines) — Claude does this better, and the full comment text is passed to Claude anyway. + +### Decision 7: Thread building in Python (not bash) + +The thread grouping logic (parse 3 API response formats, group by `in_reply_to_id`, group by file proximity within 10 lines, filter bots/orphans/oversized) is ~200 lines of JSON manipulation. This is fragile in bash+jq. A `build_threads.py` script handles thread construction using the same stdlib-only, `subprocess`-based pattern as `check_replied.py`. + +### Decision 8: Self-contained clone + +Always do a fresh blobless clone. Use `git pull --ff-only` (not `--rebase`) to stay consistent with safety rules that forbid rebase. + +--- + +## Prerequisites + +1. **`safety.sh` stable** — the review handler sources it for `audit_log()`, `check_commit_limit()`, `gh_retry()`, etc. +2. **GitHub App token** — required for pushing commits.

Follow these guidelines to produce +high-quality, reviewer-satisfying responses. + +## Interpreting Reviewer Intent — 5-Level Categorization + +Categorize each review comment by priority. Process in this order: + +1. **ACTION_INSTRUCTION** (highest priority): Repo-level operations — verify, + run tests, update branch. Execute the requested operation ONLY if it is + within your allowed tools. For rebase, squash, or force-push requests, + reply explaining that these operations require human intervention. + +2. **BLOCKING**: Critical changes — security issues, bugs, breaking changes, + correctness problems. Must be addressed before merge. + +3. **CHANGE_REQUEST**: Code improvements or refactoring — rename variables, + extract functions, restructure logic, update error messages. Make the + requested change. + +4. **QUESTION**: Requests for clarification — "why did you...?", "what + happens when...?", "is this intentional?". Reply with explanation only. + Do NOT change code for questions. + +5. **SUGGESTION** (lowest priority): Optional improvements — nit, "consider", + "maybe", "you could", "it might be better". Treat as a code change request + unless ambiguous. If ambiguous, reply asking for clarification. + +**Approval with minor note** — ("LGTM but...", "looks good, one thing..."): +Address the noted item as a CHANGE_REQUEST. + +## Making Code Changes + +1. **Read before writing**: Always read the full function/method containing the + target line before making changes. Use at least 30 lines of surrounding context. + +2. **Minimal changes**: Only modify what the review comment asks for. Do not + refactor adjacent code, rename unrelated variables, or "improve" things the + reviewer didn't mention. + +3. **Preserve style**: Match the existing code's conventions: + - Import grouping and ordering (stdlib, external, internal) + - Error handling patterns (wrap with `fmt.Errorf("context: %w", err)`) + - Naming conventions (check other files in the same package) + - Comment style and density + +4. **Verify compilation**: After every change, run: + - `go build ./...` — must pass + - `go vet ./...` — must pass + If either fails, revert your change and report the compilation error in your + reply instead of pushing broken code. + +5. **Pre-push verification**: Detect and run the appropriate verification: + - `Makefile` with `verify` target -> `make verify` + - `Makefile` with `lint` target -> `make lint` + - `go.mod` exists -> `go build ./...` and `go vet ./...` + Maximum 3 retry attempts. Do NOT push code that fails verification. + +6. **One commit per thread**: Each review thread gets at most one commit. Use + message format: `fix: — oape-pr-agent` + **New commits only** — never amend existing commits (no force-push in CI). + +7. **Stage and commit**: + - `git add ` (never `git add .` or `git add -A`) + - `git commit -m "fix: — oape-pr-agent"` + - Do NOT push — all commits are pushed in a single batch after all threads. + +## Replying to Comments + +1. **Template**: + `Done. [1-line what changed]. [Optional 1-line why]` + +2. **For code changes**: After pushing, reply to the review thread. + Example: `Done. Renamed GetFoo to fetchFoo in pkg/controller/reconciler.go. + Matches the package's existing naming convention.` + +3. **For questions**: Provide a concise, factual answer based on the actual code. + Reference specific lines or functions. Do not speculate about intent if the + code is ambiguous — describe what the code does and let the reviewer decide. + +4. **For uncertainty**: If you cannot confidently make the requested change + (ambiguous request, complex refactor, unclear scope), reply explaining what + you understand and what you're unsure about. Do not guess. + +5. **For invalid requests**: If the requested change is incorrect, would + introduce a bug, or is based on a misunderstanding of the code, decline it. + Reply with a technical explanation of 3-5 sentences including file:line + references explaining why the suggestion should not be applied. Do not + implement changes you believe are wrong — a clear explanation is more + valuable than a broken fix. + +6. **Reply format**: + - For inline comments: `gh api repos/{owner}/{repo}/pulls/{pr}/comments/{id}/replies -f "body="` + - For top-level comments: `gh pr comment {pr} --repo {owner}/{repo} -b ""` + - Never respond via both methods for the same thread + +7. **Reply signature**: All replies MUST end with: + ``` + --- + *AI-assisted response via Claude Code* + ``` + This signature is used by `check_replied.py` for duplicate detection. + +8. **Tone**: Professional, concise, helpful. No emojis, no filler ("Great + catch!", "Sure thing!"). State what was done or what the answer is. + +## Duplicate Prevention + +Before posting ANY reply, verify you haven't already responded using `check_replied.py`: + +```bash +python3 check_replied.py --type +``` + +Where `` is one of: `issue_comment`, `review_thread`, or `review_comment`. + +- **Exit code 0**: Safe to reply (no existing bot reply found) +- **Exit code 1**: Skip — already replied +- **Exit code 2**: Error — proceed with caution (default to safe-to-reply) + +## Comment Grouping + +Group inline comments by file and proximity (within 10 lines of each other). +When multiple comments relate to the same concern: +- Make the code change once +- Post a reply to EACH comment individually referencing the same commit + +## OpenShift Operator Conventions + +When making changes to OpenShift operator code, follow these conventions: + +1. **Error handling**: Use `fmt.Errorf("context: %w", err)` for wrapped errors. + Lowercase error messages, no trailing punctuation. + +2. **Status conditions**: Use `meta.SetStatusCondition()` or the operator's + existing condition helpers. Include `Type`, `Status`, `Reason`, and `Message`. + +3. **RBAC markers**: If a code change requires new API access, add the + appropriate `// +kubebuilder:rbac` marker above the Reconcile function. + +4. **Generated code**: If your change modifies `_types.go` files, remind the + reviewer that `make generate && make manifests` may need to be run (but do + not run it yourself unless the review specifically asks for it). + +5. **Testing**: If the reviewer asks you to add or modify a test, place it in + the same package's `_test.go` file. Use table-driven tests if the package + already uses them. diff --git a/plugins/oape/skills/address-review-comments/build_threads.py b/plugins/oape/skills/address-review-comments/build_threads.py new
