executing-plans

A procedure for carrying out an existing written software implementation plan. It reviews the plan, performs its tasks in order, records progress, and runs the checks specified by the plan.

In plain words
What is it for?
Use it when a plan already exists and needs to be implemented in a separate session or without subagent dispatch. It tracks each task through completion and verifies the finished work.
Why use it?
It keeps multi-step implementation work organized and resumable if the session is interrupted. It also surfaces concerns about the plan before changes begin.

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

executing-plans 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.

Origin

This is a copy

80% identical to executing-plans — 15 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Executing Plans

Overview

Load plan, review critically, execute all tasks, report when complete.

Announce at start: "I'm using the executing-plans skill to implement this plan."

Routing: Use this skill when subagent dispatch is unavailable OR the user wants a separate execution session; otherwise use subagent-driven-development.

The Process

Step 1: Load and Review Plan

  1. Ensure an isolated workspace: use using-git-worktrees to create one or verify the existing one
  2. Read plan file
  3. Review critically - identify any questions or concerns about the plan
  4. If concerns: Raise them with the user before starting
  5. If no concerns: Create todos for the plan items and proceed

Step 2: Execute Tasks

For each task:

  1. Mark as in_progress
  2. Follow each step exactly (plan has bite-sized steps)
  3. Run verifications as specified
  4. Mark as completed

Track completed tasks in a ledger file (reuse subagent-driven-development's convention: <workspace>/progress.md, first line naming the plan file, one Task <N>: complete line per finished task) so a compacted session can resume where it stopped.

Step 3: Complete Development

After all tasks complete and verified:

  • Before claiming the work is done, apply verification-before-completion: run the verification commands and confirm their output first
  • Announce: "I'm using the finishing-a-development-branch skill to complete this work."
  • REQUIRED SUB-SKILL: Use finishing-a-development-branch
  • Follow that skill to verify tests, present options, execute choice

When to Stop and Ask for Help

STOP executing immediately when:

  • Hit a blocker (missing dependency, test fails, instruction unclear)
  • Plan has critical gaps preventing starting
  • You don't understand an instruction
  • Verification fails repeatedly

Ask for clarification rather than guessing.

When to Revisit Earlier Steps

Return to Review (Step 1) when:

  • The user updates the plan based on your feedback
  • Fundamental approach needs rethinking

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.
