truthmark-realize

truthmark-realize is a skill for Claude Code, Codex from merlinhu1/truthmark. It costs 60 tokens per session (247 once invoked), scanned A, original, MIT.

A coding workflow for turning Truthmark truth documents into working code. Truthmark documents are repository files that describe the intended behavior or rules of a project.

In plain words
What is it for?
Use it when explicitly implementing Truthmark documentation in the project’s functional code.
Why use it?
It gives developers a defined process for implementing documented behavior while keeping those source documents unchanged.

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

truthmark-realize 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 6d 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

Truthmark Realize

Use this skill only when the user explicitly asks to realize truth docs into code.

Quick procedure:

  • Follow repository instruction files that exist in this checkout; do not assume any optional policy path exists.
  • Read the source truth docs, inspect .truthmark/config.yml and configured route files (docs/truthmark/routes/areas.md; docs/truthmark/routes/areas/) only when they exist, then inspect tests and relevant functional code directly.
  • Truth docs lead; code follows.
  • may write functional code only; must not edit truth docs or truth routing while realizing those docs.

Progressive disclosure:

  • support/procedure.md — read before edits or detailed auditing; contains core review questions
  • support/report-template.md — read before the final report
Files

What ships with it

3 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.
