work

work is a skill for Claude Code, Codex from wrannaman/agentic-engineering. It costs 13 tokens per session (767 once invoked), scanned A, original, MIT.

An implementation workflow that follows a written plan one step at a time and checks the result as it goes.

In plain words
What is it for?
Use it to carry out planned feature work or bug fixes, review the plan, set up Git work, and run the plan’s validation checks.
Why use it?
It reduces missed steps and catches problems during development instead of only at the end.

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

work 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 2mo 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.

Work Skill

Execute an implementation plan step by step with verification.

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

Better with subagents: If the platform supports subagents, the subagent route produces higher quality output. See Step 4.

Input

/work <harness-dir(.claude|.codex)>/plans/2025-01-07-feature-name.md

Step 1: Load & Review Plan

  1. Read the plan file
  2. Review critically — identify questions or concerns before starting
  3. If concerns: raise with user before proceeding
  4. If no concerns: create TodoWrite task list from steps
  5. Extract and note:
    • All implementation steps (full text — needed for subagent route)
    • Validation Methodology section (primary validation command)
    • PR Stack section (branch names and step boundaries)

Step 2: Worktree Setup

  1. Check existing worktrees: git gtr list
  2. Derive branch name from plan filename (2026-03-06-add-auth.md → feat/add-auth)
  3. If matching worktree exists → AskUserQuestion: Use existing? Create new? Work in current dir?
  4. If no matching worktree → AskUserQuestion: Create worktree? Work in current dir?
    • Create → invoke /worktree create <branch>
    • Use existing → cd into it, copy <harness-dir(.claude|.codex)>/plans/ if missing

CRITICAL: Always use cwd for file operations — never paths from config.toml. This breaks in worktrees where cwd differs from toolkit_directory.

Step 3: Initialize Stack

Parse the PR Stack table from the plan, then detect the active stack workflow:

  1. list_kb_documents for partition git-stacks
  2. read_kb_document_by_path for /index.md
  3. Run dedicated-client checks from /index.md; classify native-git if no dedicated client found
  4. Load matching client doc before running any stack command:
    • charcoal → /charcoal.md, git-town → /git-town.md, native-git → /native-git.md
  5. Check current branch: git branch --show-current
  6. If on main/trunk, create or switch to the first PR branch using the detected workflow

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.
