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 | $0.00245 | $0.00245 |
| Opus 5 | $0.00122 | $0.00122 |
| Sonnet 5 | $0.00049 | $0.00049 |
| Haiku 4.5 | $0.00024 | $0.00024 |
Grade A, and why
trellis AGENTS.md 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 yesterday.
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
Trellis Agent Guidelines
Instructions for AI agents (Claude Code, etc.) working in this repository.
Before Every Commit
Run the automated test suite:
.venv/bin/pytest tests/ -x -q
For UI-touching changes (templates, routes, frontend JS), also run the browser test:
/test-trellis
Navigate to the running Trellis instance (default: http://localhost:8000), work through the checklist in the skill, and confirm all pages load correctly before committing.
After Changing Pipeline Logic
Re-run the E2E pipeline tests explicitly:
.venv/bin/pytest tests/test_e2e_pipeline.py tests/test_e2e_web_pipeline.py -v
Release Checklist
Before bumping version and pushing a release:
- All tests pass
/test-trellisbrowser test passestrellis serve --list-log-formatsworks/healthz,/readyz,/metricsendpoints respond correctly- Version bumped in

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.

trellis AGENTS.md is an instructions file published in the GitHub repository terraboops/trellis (2 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 245 tokens to every session, about $0.0012 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 2026-08-31.
