If the PR adds a warning or non-fatal log line, run the command in BOTH + `--json` mode AND human mode. The two surfaces in `commands/.py` are + easy to forget separately. + +If you cannot reproduce because of missing credentials, network issues, or +absent test data, SAY SO IN THE VERIFICATION LOG.

You do + NOT run `git checkout`, `git switch`, `git reset`, `git rebase`, `git + merge`, `git push`. The only filesystem write you make is the temp + markdown file in `/tmp/`. +3. **Stay in the diff.** Do NOT propose unrelated cleanup ("while I'm + here, this older comment is unclear..."). Stick to what this PR + changed. +4. **CI is not your job.** Do NOT review for lint/format issues unless + you have evidence CI didn't actually run. `make check` passing is + sufficient signal that ruff was happy. +5. **Verify, don't assume.** Every claim in your "Verification log" + corresponds to a real command you ran. If you say `make check` passed, + you ran it. If you can't run something (missing creds, no network), + say so explicitly in the verification log. +6. **Cite `file:line` for every finding.** "The helper function" is not + a finding; "`storage_service.py:172`" is. +7. **≤ 15 findings total.** If you have more, you're nitpicking.

The subagent runs the full playbook from `CONTRIBUTING.md` +(3-layer architecture, Plugin synchronization map, silent-drift hunt, +test coverage, behavior verification) in a fresh context window and +posts ONE comment review on the PR. + +## Behavior + +1. **Resolve the target PR** from `$ARGUMENTS`: + - **Empty `$ARGUMENTS`**: detect the open PR for the current git branch. + Run: + ```bash + gh pr view --json number,url,baseRefName,headRefName,title,state 2>&1 + ``` + If the command errors with "no pull requests found for branch X" or any + other failure, abort with: *"No open PR found for the current branch. + Either: (a) push your branch and open a PR via `gh pr create`, or (b) + call `/kbagent:review <PR_NUMBER>` explicitly."* + + - **`$ARGUMENTS` is a number** (e.g. `227`) or a URL (e.g. + `https://github.com/.../pull/227`): extract the PR number and verify + it exists: + ```bash + gh pr view <N> --json number,url,baseRefName,headRefName,title,state + ``` + If `state != "OPEN"`, abort with: *"PR #<N> is not open (state=<state>)."* + + - **`$ARGUMENTS` has trailing free text** after the number / URL: treat + the trailing text as a `<focus>` hint to forward to the subagent + (e.g. `/kbagent:review 227 storage layer regression risk`). + +2. **Sanity-check the working tree**: + ```bash + git rev-parse --abbrev-ref HEAD + ``` + If the current branch is not the PR's `headRefName`, warn (don't abort): + *"You're on branch X but the PR is for branch Y. The subagent reads + source at HEAD via the working tree -- if these aren't the same commit, + the review may target stale code. Run `gh pr checkout <N>` first if you + want a strict review."* + If the user has uncommitted changes (`git status --porcelain` non-empty), + warn similarly. The user can override by re-invoking after stashing. + +3. **Spawn the `kbagent-pr-reviewer` subagent** via the `Task` tool: + - `subagent_type`: `kbagent-pr-reviewer` + - `description`: `Review PR #<N>` (6-8 word task summary) + - `prompt`: build a TASK message containing the resolved fields: + ``` + Review the kbagent PR below. Follow your system prompt's playbook + end-to-end. Post the report via gh pr review --comment --body-file. + + <pr_url>https://github.com/.../pull/<N></pr_url> + <pr_number><N></pr_number> + <branch><headRefName></branch> + <base_branch><baseRefName></base_branch> + <focus>{{trailing args, or empty}}</focus> + ``` + +4. **Relay the subagent's brief summary to the user**. The subagent posts the + full report to GitHub itself; do NOT duplicate the post. If the + subagent's summary indicates the post failed (auth, rate limit, etc.), + surface its full report so the user can paste manually. + +## Examples + +``` +/kbagent:review # auto-detect PR for current branch +/kbagent:review 227 # explicit PR number +/kbagent:review https://github.com/padak/keboola_agent_cli/pull/227 +/kbagent:review 227 focus on the new cache semantics # forwarded as <focus> +``` + +## Why this lives as `slash command + subagent` (not just inline) + +- The slash command runs in the user's main conversation context. It can + see the current branch, current uncommitted state, and the user's task + history. It cannot pollute the main agent's context with the 1500+ token + review playbook. +- The subagent runs in a fresh window with the full playbook loaded at + full weight. The non-negotiable rules (read-only, comment-only, ≤15 + findings, file:line citations, verify-don't-assume) survive long + sessions because they're loaded once on a clean slate -- which is + exactly the discipline gap that makes review-by-main-context unreliable. + +See `plugins/kbagent/agents/kbagent-pr-reviewer.md` for the full subagent +system prompt. + +## Hard guardrails (the slash command is allow-listed; the subagent is too) + +- The subagent has only `Bash, Read, Grep, Glob`. No `Write`, no `Edit`, + no working-tree mutation. +- The subagent's prompt forbids `gh pr review --approve`, `--request-changes`, + `gh pr merge`, `gh pr close`, `gh pr ready`, `git push`. The only + GitHub-side mutation is `gh pr review --comment --body-file`. +- The verdict in the comment body is advice. The human author makes the + final approve / request-changes decision via GitHub UI or `gh pr review` + themselves.
