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 | $0.00034 | $0.00300 |
| Opus 5 | $0.00017 | $0.00150 |
| Sonnet 5 | $0.00007 | $0.00060 |
| Haiku 4.5 | $0.00003 | $0.00030 |
Grade A, and why
engram-project-structure 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 2d 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
When to Use
Use this skill when:
- Creating a new package, file, or directory
- Deciding where code belongs
- Adding tests, templates, assets, or docs
Placement Rules
- Put behavior near its domain, not near the caller that happens to use it.
- Keep templates in
internal/cloud/dashboard/*.templand generated files checked in. - Keep dashboard styling in
internal/cloud/dashboard/static/styles.cssunless a new static asset is clearly needed. - Put HTTP handlers in server packages, not in store packages.
- Put persistence queries in store/cloudstore, not in handlers.
File Creation Rules
- New route -> handler + tests in dashboard/server package
- New DB behavior -> store/cloudstore code + focused tests
- New UI partial/page -> templ component + generated
_templ.go - New contributor guidance -> update docs/catalog in same change
Anti-Patterns
- Do not mix SQL, HTML, and transport logic in one file.
- Do not create utility packages for one-off helpers.
- Do not add package layers unless they remove real coupling.
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.

engram-project-structure is a skill published in the GitHub repository Gentleman-Programming/engram (6,266 stars, last pushed today), licensed MIT. It adds 34 tokens to every session and 300 once invoked, about $0.0002 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.
