execute

A method for carrying out coding tasks from initial scope through implementation, verification, and commits.

In plain words
What is it for?
Planning and implementing features, fixes, or other software changes while tracking tasks and using separate worktrees.
Why use it?
It gives the agent a repeatable way to break work into manageable changes and confirm the result.

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

execute 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 2d ago.

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

Execute

Implementation methodology. Loads alongside the domain skill (e.g., "noodle") — this teaches process, the domain skill teaches the codebase. Operate fully autonomously. Never ask the user. Don't stop until the work is fully complete.

Track all work with Tasks (TaskCreate, TaskUpdate, TaskList). One task per decomposed change; mark in_progress when starting, completed when done.

1. Scope

Establish what needs doing:

  • Plan phase: Read the assigned phase from brain/plans/. Read the overview for scope boundaries. Invoke Skill(backlog) for project-specific context. Load domain skills listed in "Applicable skills."
  • Backlog item: Read the todo from brain/todos.md. If a linked plan exists, read it. Otherwise, scope from the description.
  • Ad-hoc request: The user prompt is the scope. Identify affected files and packages before starting.

Output: a clear, bounded description of what changes and what doesn't.

2. Decompose

Break scope into discrete changes. Each change:

  • One function/type + its tests, OR one bug fix
  • Independently compilable
  • One conventional commit

Single-change scopes skip decomposition.

3. Implement

Worktree First — Non-Negotiable

Never edit files on main. Multiple sessions run concurrently; editing main causes merge conflicts and lost work.

If CWD is already inside .worktrees/, use it. Otherwise: noodle worktree create <descriptive-name>

Use absolute paths or noodle worktree exec <name> <cmd>. Never cd into a worktree — if it gets removed while the shell is inside, the session dies permanently.

Commit inside the worktree. When done: noodle worktree merge <name>

Skip only when the user is interactively driving a single-agent session and explicitly chooses main.

Delegation

  • Self-execute: Single change, or tightly coupled changes (shared types, sequential dependencies).
  • Sub-agents: 2+ independent changes touching different files. Front-load context: scope, relevant code, domain skill name.
  • Team execution: 2+ parallelizable phases in a plan. See references/team-execution.md.
  • Codex: Mechanical work not requiring judgment (renames, boilerplate, repetitive edits). Never for architectural decisions.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

execute is a skill published in the GitHub repository poteto/noodle (263 stars, last pushed 5mo ago), licensed MIT. It adds 41 tokens to every session and 899 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
