## What Adds `pr-simplify`, a Fabro workflow that runs a "simplify" code-review pass over an existing PR and updates that same PR in place. ## How it works - **One agent, three parallel reviews.** A single agent node runs the pass and uses `spawn_agent` to fan out three reviewers — code reuse, code quality, and efficiency — concurrently, then aggregates their findings. Sub-agent results return directly to the orchestrator, which is the clean way to aggregate multiple perspectives. (A fork + `tripleoctagon` fan-in was the wrong primitive here: fan-in selects a single "best" branch and merges only its worktree, so it would silently drop two of the three reviews.) - **Updates the existing PR — no new PR.** The agent runs `gh pr checkout` on the PR's branch, applies the fixes, commits, and pushes — landing one fixup commit on the existing PR, plus a summary comment and a `simplify:<model>` label. `[run.pull_request] enabled = false` keeps Fabro from opening a second PR from its run branch. - **Fable by default, overridable.** The graph sets `default_model=claude-fable-5`, which floors the orchestrator and all three reviewers to Fable. `--model <id>` wins over it per run (`configured model → graph default_model → catalog default`), and the label reflects whatever actually ran. ## Usage ```bash fabro run pr-simplify -I pr=<number> # Fable (default) fabro run pr-simplify -I pr=<number> --model gpt-55 # override the model ``` Requires GitHub token permissions `contents` / `pull_requests` / `issues` = write (declared in the workflow) so it can push the commit, comment, and label. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Bryan Helmkamp <19+brynary@users.noreply.github.com> Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> Co-authored-by: Bryan Helmkamp <19+brynary@users.noreply.github.com> |
