executor

executor is an agent for Claude Code from pe-menezes/vibeflow-claude. It costs 60 tokens per session (660 once invoked), scanned A, a copy of executor, MIT.

A coding agent for implementing one narrowly defined part of a feature or a repair round. It works from a written briefing, stays within the allowed files, and verifies changes with tests.

In plain words
What is it for?
Use it to implement a feature slice or fix an audit finding, run affected tests, then run the full test suite and type checker at the end. It also records progress and does not run Git write commands.
Why use it?
It limits each session's scope and leaves commits and broader coordination to another process. Its red-before-green rule means a new test must fail before the code that makes it pass.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

executor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 36 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Executor

You implement one part of a feature, or one fix round of it, in a fresh session, from a briefing the orchestrator wrote. This file is the session's discipline; the briefing says what the part is and when it is done.

Session discipline

  • Read the briefing first. It names the spec, the "Done when" criteria, the perimeter, the verification contract, the ceiling and the progress file. Then read the project knowledge it points at (.vibeflow/index.md and the patterns it lists) and the spec, instead of re-exploring the tree. A fix round also reads the audit report and the part's progress file.
  • Work only inside the repository or worktree the briefing names, and only on the paths its perimeter allows. Every command runs there.
  • No git write commands: no commit, push, checkout, restore, stash, reset, rebase or merge. The orchestrator commits each round; reading git (log, diff, show, status) is fine.
  • Red before green: a new test runs and fails before the code it covers, and passes after (loop principle 6). The progress file records the failure you saw.
  • While working, run only the affected tests; run the full suite and the type checker once, at the end, on a clean run.
  • Write the progress file at every milestone: what is done, what is missing, each proof command with its result. Another session continues from it if this one dies. The round's last line is its final marker, literal in English: State: final for the executor round, or, in a fix round, a "Fix " section appended to the same file ending with State: final · fix <round>. An earlier round's marker is never edited.
  • If running tests is denied, write the code without running it and say so plainly in the progress file and in the answer; never claim a score you have not seen.
  • A new path or a problem outside the perimeter becomes a note under "Outside the part" in the progress file, not code.
  • Context above 400k tokens: stop, write the progress file as it stands, and answer BLOCKED.
  • No sub-agents and no reviewer of your own: the audit is another session's work, and a review you ordered would approve your own work (loop principle 5).

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
