trace-first-starter: Skill for Claude Code

.agents/skills/tfw-review/SKILL.md

tfw-review is a skill for Claude Code, Codex from saubakirov/trace-first-starter. It costs 46 tokens per session (275 once invoked), scanned A, original, MIT.

A repository command that reviews a completed Trace-First Workflow, a documented process that connects requirements and implementation to supporting evidence.

In plain words
What is it for?
It is for reviewing workflow artifacts, checking implementation evidence, and producing an approve-or-reject review result without changing the implementation.
Why use it?
It checks whether the workflow's claims match the actual code, files, and test results instead of accepting declarations without verification.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is saubakirov/trace-first-starter's own configuration. It tells Claude Code and Codex how to work on trace-first-starter itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything trace-first-starter configures →

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

tfw-review 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.

What it actually says

/tfw-review

This repository skill implements the /tfw-review command.

Contract

  • Treat literal /tfw-review input as a command. Also accept tfw-review and matching natural-language requests.
  • Confirm the repository contains .tfw/.
  • Enforce the Reviewer role lock: permit review stage files and REVIEW; forbid ONB, RF, HL, TS, RES, code, and implementation changes.
  • Read .tfw/workflows/review.md completely and follow its stage-specific Read Contract. Root instructions are already active; do not independently preload AGENTS.md or any full common library. Preserve separate Verify PV and Judge Purpose reads.
  • Open .tfw/templates/review/* and .tfw/templates/REVIEW.md only at their stage gates; verify declarations against actual files/evidence and stop after the verdict and direct Coordinator return.

After APPROVE, return to the existing Coordinator for the canonical closing route. Remain the independent Reviewer for affected final claims; never perform capture or declare DONE.

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.
