Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00021 | $0.00318 |
| Opus 5 | $0.00010 | $0.00159 |
| Sonnet 5 | $0.00004 | $0.00064 |
| Haiku 4.5 | $0.00002 | $0.00032 |
Grade A, and why
Build Trestle Workspace 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.
What it actually says
/oscal-document-workbench:build-trestle-workspace
Start a Compliance Trestle workspace for OSCAL authoring and validation.
How to run
bash plugins/document-transform/oscal-document-workbench/scripts/bootstrap-trestle-workspace.sh <workspace> [--profile <name>] [--oscal-version <version>] [--overwrite]
Arguments
<workspace>: import workspace that will containtrestle-workspace/andreports/--profile <name>: optional baseline or profile label such asfedramp-moderate--oscal-version <version>: optional OSCAL version note. Defaults to the installed Trestle OSCAL version when available.--overwrite: replace an existing generatedtrestle-workspace/
Outputs
trestle-workspace/reports/import-summary.mdreports/unmapped-items.md
Exit codes
0: success2: bad arguments or unsafe overwrite attempt3:trestle initfailed
Safety notes
- Keep source files unchanged.
- Maintain source traceability for every mapped OSCAL field.
- Mark uncertain mappings as
needs_review. - Do not treat structural validation as an audit opinion.
- Do not commit sensitive customer evidence or real SSPs.
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.
