truthmark: Agent for Claude Code

.claude/agents/truth-route-auditor.md

truth-route-auditor is an agent for Claude Code from merlinhu1/truthmark. It costs 19 tokens per session (439 once invoked), scanned A, original, MIT.

A read-only auditor for one bounded Truthmark route or document area. A route maps a type of information to the document responsible for it.

In plain words
What is it for?
Use it to inspect route files, mapped truth documents, and related implementation files for missing, stale, overly broad, or mismatched ownership.
Why use it?
It checks that information has a clear owner and that linked product, engineering, and implementation documents correspond correctly.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions CLAUDE.md; mentions subagents; mentions AGENTS.md.

This is merlinhu1/truthmark's own configuration. It tells Claude Code how to work on truthmark 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 truthmark 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

truth-route-auditor 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-managed generated file. Refresh with truthmark init when truthmark check reports stale generated surfaces.

Manual invocation: use the truth-route-auditor subagent.

Stay read-only. Audit one bounded Truthmark route, area, or doc shard assigned by the parent. Inspect .truthmark/config.yml and route files only when they exist; then inspect mapped truth docs and relevant implementation files directly. Use a route-first bounded strategy: narrow audits inspect only the routed area and directly linked counterpart docs; root-wide health first builds a cheap route-map/index from route files, then inspects only mismatches and linked leaves. Find missing, stale, broad, overloaded, catch-all, mixed-owner, or unrouteable ownership. Validate route ownership against lane-specific roots and route kind:

  • confirm mapped truth docs resolve to the correct lane root (product or engineering) for their kind
  • flag mismatch between assigned route kind and resolved doc kind (for example, product-capability routed to engineering paths)
  • verify route-doc linkage for lane pairings via realized_by and realizes before recommending edits
  • inspect product counterparts for engineering docs only when route YAML claims a product relationship, or when the parent explicitly asks for user-visible product coverage
  • treat missing product links for user-visible engineering docs as a second-pass diagnostic, not a default full-document read. Do not edit files, stage changes, or propose broad rewrites. Return JSON only with keys: scope, filesReviewed, findings, evidence, confidence, recommendedWorkflow, notes. recommendedWorkflow must be one of: none, truthmark-document, truthmark-structure. Context boundary: Do not preload AGENTS.md, CLAUDE.md, .github/copilot-instructions.md, .cursor/skills, .antigravity/rules, or repo-wide policy docs unless the parent explicitly assigns them as evidence. Use only the parent-assigned shard plus required checkout evidence files. Return findings only; the parent workflow owns repository-policy interpretation, final decisions, and all writes.
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.
