What it does

Claude Simplify Wrapper is an agent skill from besimple-oss/broccoli. Run Claude's built-in /simplify skill on BASESHA..HEAD, validate checks, and commit.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts and reference files (for example `references/prompts/simplify-validator-system.md` and `scripts/run_simplify_loop.py`).

It sits in Development. It works with Git. The repository describes itself as: Broccoli turns Linear tickets into shipped PRs — powered by Claude and Codex, running on your own Google Cloud or Blaxel containers. The licence is MIT.

When your agent uses it

  • Development work in your project

Example prompts

  • “/claude-simplify-wrapper”

Requirements

  • Python 3

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. Simplify subprocess — Invokes claude with the /simplify prompt. The built-in skill handles its own three parallel agents and applies fixes…
  2. Validate+commit subprocess — A second claude subprocess that runs the repo's standard build/lint/test commands, fixes only breakages…

What it can do on your machine

Read from SKILL.md and the folder at commit 6cad3b9. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • git
    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Claude Simplify Wrapper loads about 1.1k tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 27 tokens; SKILL.md has 455 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~27
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description
Run Claude's built-in /simplify skill on BASE_SHA..HEAD, validate checks, and commit.

Simplify Loop

Input: a git base SHA/ref to simplify against (for example: <sha> or HEAD~1).

Preconditions

  • Confirm you are in the intended repo: git rev-parse --show-toplevel
  • Ensure you have a base commit SHA (prefer the commit from before the change set).
  • Start from a clean working tree (required):
    • git status --porcelain should be empty.
  • Ensure git can create commits (stop if missing):
    • If commits fail due to missing identity, configure user.name and user.email.
  • Only claude CLI is required (no codex dependency).

Scope / intent

  • This is a simplification pass, not a general code review.
  • Invokes Claude's built-in /simplify skill which runs three parallel agents internally:
    • Code reuse (find and eliminate duplication)
    • Code quality (simplify convoluted logic)
    • Code efficiency (remove unnecessary work)
  • Changes are validated (build/lint/test) and committed automatically.

Architecture

Two-phase per iteration:

  1. Simplify subprocess — Invokes claude with the /simplify prompt. The built-in skill handles its own three parallel agents and applies fixes directly to the working tree.
  2. Validate+commit subprocess — A second claude subprocess that runs the repo's standard build/lint/test commands, fixes only breakages introduced by the simplify phase, stages and commits all changes, and emits LOOP_STATUS: {...} so the wrapper can decide whether to continue.

The loop stops when:

  • The simplify phase produces no working-tree changes (nothing to simplify)
  • The validate phase fails to make checks green
  • Max iterations reached

Expected runtime

Typically runs 5–20 minutes per iteration. Allow at least 30 minutes for a single iteration.

Do not interrupt/restart the subagent if it looks stuck. The loop script owns stuck/timeout handling and will exit on its own when it completes or when --timeout is reached.

Options:

  • --max-iterations N (default: 1)
  • --model <model> (default: claude-sonnet-4-6)
  • --effort <effort> (default: high)
  • --progress-log <path> and --heartbeat-seconds N
  • --artifacts-dir <path> (optional; stores subprocess outputs)
  • --timeout N (per-subprocess timeout in seconds; default: 3600)
  • --review-only (run simplify phase only; do not validate or commit)
  • --scope <pathspec> (repeatable; restricts git diff to those paths)

Claude automation knobs (env vars; defaults shown):

  • PROMPT_TEMPLATES_CLAUDE_OUTPUT_FORMAT=stream-json (text|json|stream-json)
  • PROMPT_TEMPLATES_CLAUDE_MIN_VERSION=2.1.33 (fail fast if installed Claude Code is older)
  • PROMPT_TEMPLATES_CLAUDE_STREAM_LOG_MAX_BYTES=10485760 (per invocation; set 0 for unlimited)
  • PROMPT_TEMPLATES_CLAUDE_INACTIVITY_TIMEOUT_SECONDS=180 (set 0 to disable)
  • PROMPT_TEMPLATES_CLAUDE_INACTIVITY_MIN_RUNTIME_SECONDS=30
  • PROMPT_TEMPLATES_CLAUDE_PROMPT_BUDGET_BYTES=0 (disabled by default; set >0 to enforce)

Behavior:

  • Each iteration runs in two fresh Claude subprocesses (claude-only, no codex required).
  • Phase 1 invokes the bundled /simplify skill which applies fixes directly.
  • Phase 2 validates changes, fixes any breakages, and commits.
  • Claude subprocesses run in a native PTY (when available) and have an inactivity timeout; on classifiable Claude automation failures the script retries once.
  • The script enforces commit hygiene per iteration: if the validator leaves working-tree changes, it auto-commits them before the next iteration.

Troubleshooting:

  • --progress-log may include full tool outputs (diffs, file contents). Treat it as sensitive; stream-json logs are truncated by default via PROMPT_TEMPLATES_CLAUDE_STREAM_LOG_MAX_BYTES.
