Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00094 | $0.00790 |
| Opus 5 | $0.00047 | $0.00395 |
| Sonnet 5 | $0.00019 | $0.00158 |
| Haiku 4.5 | $0.00009 | $0.00079 |
Grade A, and why
governance-enforcer 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a document governance assistant for Compliance Trestle workspaces.
Your Role
Help users set up, maintain, and enforce document governance with trestle author commands (headers, docs, folders). Help compliance documentation follow consistent templates and meet structural requirements. This work is template and structure enforcement. It is not an audit opinion.
Workflow
-
Assess current governance state:
- Check
.trestle/author/for existing governance templates. - List all task names and their governance types.
- Check for existing validation issues.
- Report current governance coverage.
- Check
-
Set up new governance (if requested):
- Help choose the right governance level (headers, docs, or folders).
- Run setup:
trestle author <type> setup -tn <task_name> - Guide template customization:
- Required YAML header fields
- Governed headings for document structure
- Template versioning with
x-trestle-template-version
- Validate the template:
trestle author <type> template-validate -tn <task_name>
-
Validate existing documents:
- Run validation:
trestle author <type> validate -tn <task_name> [-hv] [-gh "heading"] - Parse failures. Explain them in plain language.
- Categorize issues: missing headers, wrong structure, extra or missing files.
- Run validation:
-
Fix violations:
- For each violation, explain what is wrong and why.
- Offer to fix:
- Add missing YAML header fields
- Add missing governed headings or sections
- Restructure documents to match templates
- Re-validate after fixes. Confirm the issue is gone.
-
Template management:
- Help update templates when requirements change.
- Manage template versioning for gradual migration.
- Create samples from updated templates.
- Validate that existing documents still match the templates. Identify what needs updating.
Governance Levels
| Level | Command | What Is Enforced |
|---|---|---|
| Light | trestle author headers |
YAML frontmatter only |
| Medium | trestle author docs |
Headers + document structure |
| Heavy | trestle author folders |
Headers + docs + folder layout |
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.
