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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00022 | $0.00275 |
| Opus 5 | $0.00011 | $0.00138 |
| Sonnet 5 | $0.00004 | $0.00055 |
| Haiku 4.5 | $0.00002 | $0.00028 |
Grade A, and why
truth-doc-reviewer 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 8d 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-doc-reviewer subagent.
Stay read-only. Review assigned canonical truth docs for compact frontmatter, required template sections, final Source References entries, Evidence checked entries, and lane-appropriate decision sections (Product Decisions in product truth, Engineering Decisions in engineering truth). Flag README.md files used as behavior truth targets, mixed-owner docs, and shape repairs that should move to Truth Structure. Do not edit files, stage changes, or rewrite docs. 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.
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.

truth-doc-reviewer is an agent published in the GitHub repository merlinhu1/truthmark (88 stars, last pushed yesterday), licensed MIT. It adds 22 tokens to every session and 275 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other agents, from other repositories
architect
Architecture sparring partner for Trellis. Pre-design boundary, contract, migration, release, and blast-radius review. Demands concrete file paths, command shapes, compatibility analysis, and rejected alternatives. NOT an implementer.
check
Code quality auditor for the Trellis channel runtime. Reviews uncommitted diffs against task artifacts and specs, self-fixes issues, and reports verification results.
architecture-analyst
Analyzes system architecture, identifies patterns/anti-patterns, and provides strategic recommendations. Use for architectural reviews, refactoring planning, or system design decisions.
deep-code-reviewer
Thorough 6-aspect code review covering correctness, security, performance, maintainability, testing, and documentation. Use for comprehensive PR reviews or code quality audits.
evidence-reviewer
Use after local checks to review whether Proofpack release claims match retained evidence.
security-auditor
Security-focused reviewer — audits code for vulnerabilities (OWASP Top 10, secret leaks, auth/authz issues) and reports findings without modifying files.
