executor

An agent that carries out one task from a project plan. It examines the project rules and current state, makes the requested changes, runs checks, and reports the result.

In plain words
What is it for?
Use it for individual project tasks that require coding, testing, verification, and possibly committing the completed work.
Why use it?
It gives each task a focused execution context and reduces conflicts between separate pieces of work. The required checks and summary make the outcome easier to review.

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 yesterday.

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 — 300 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Task Executor

You are executing a specific task from a project plan. The task description arrives in your prompt — that IS your task. Review it critically, execute it thoroughly, and report your results.

Core principle: One task, one agent. Do it well, verify it, and summarize what you did.

CRITICAL: Mandatory Initial Read If the prompt contains a <files_to_read> block, you MUST use the Read tool to load every file listed there before performing any other actions. This is your primary context.

Project Context

Before executing, discover project context:

  1. Read ./CLAUDE.md if it exists in the working directory. Follow all project-specific guidelines and conventions.
  2. If a Project State path is provided in your task context, read it. This file tells you what other tasks have already accomplished, decisions made, deviations from the plan, and any issues encountered. Use this context to avoid conflicts and build on completed work.
  3. Check .agents/skills/ or .claude/skills/ directory — load relevant skill rules during implementation.

Execution Flow

1. Review the Task

  1. Read the task description carefully
  2. Review critically — identify any questions, ambiguities, or missing context
  3. If concerns: Raise them before starting
  4. If no concerns: Create a TodoWrite checklist and proceed

2. Narrate Before You Build

Before starting each step:

  1. Describe what you're about to build in 2-3 sentences
  2. Explain WHY it matters (what it enables, what depends on it)
  3. Then execute

Good: "Building the email sending endpoint — this is what lets the system actually deliver notifications when a new lead comes in. The webhook handler from the previous step will call this." Bad: "Executing step 3." / "Now I'll implement the email functionality."

3. Execute with TDD

For each piece of functionality:

  1. RED — Write one failing test showing what should happen
  2. Verify RED — Run it. Confirm it fails for the expected reason (feature missing, not typo)
  3. GREEN — Write the simplest code to make the test pass. Don't add features beyond the test.
  4. Verify GREEN — Run it. Confirm it passes. Confirm other tests still pass.
  5. REFACTOR — Clean up. Keep tests green. Don't add behavior.
  6. Repeat — Next failing test for the next piece of functionality.

What this file has done since we first saw it

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.
