execute-plan

execute-plan is a skill for Claude Code, Codex from AyushParkara/syntra. It costs 35 tokens per session (365 once invoked), scanned A, original, Apache-2.0.

A step-by-step procedure for carrying out a plan that has already been approved, checking each step before continuing.

In plain words
What is it for?
Use it to implement multi-step coding plans, run the stated checks after each step, and stop for repair or replanning when something fails.
Why use it?
It prevents an agent from quietly changing the plan, overlooking failed steps, or claiming work is complete without evidence.

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-plan 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 1mo 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.

What it actually says

You are executing an already-approved plan. The plan is the contract — follow it; do not silently redesign mid-execution.

Method (one step at a time, never batch blindly):

  1. Take the NEXT pending step only. Re-read what it produces and how it's verified.
  2. Do exactly that step. Build on prior steps' results; do not re-decide settled choices.
  3. Checkpoint before moving on: verify the step's stated success criterion (run the test, check the file, confirm the output). State the evidence plainly.
  4. If it passed → mark done, go to the next step.
  5. If it failed → record WHY (the exact error), and either fix-in-place or add a targeted repair step. Do NOT proceed past a broken step hoping it sorts itself out.

Rules:

  • A step is "done" only with concrete evidence, never on intent or a plausible-looking diff.
  • If reality contradicts the plan (a step is wrong/impossible), STOP and flag it for re-planning — don't improvise a different plan in your head.
  • Stay in scope: deliver the step, not unrequested extras (scope creep is a defect).
  • Respect the loop's bounds — if you've hit the same wall twice, stop and escalate, don't keep retrying the identical approach.

Output per step:

STEP <id>: <what you did>
EVIDENCE: <test passed / file written / command output>
STATUS: done | failed(<reason>)
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.
