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 | $0.00032 | $0.00201 |
| Opus 5 | $0.00016 | $0.00101 |
| Sonnet 5 | $0.00006 | $0.00040 |
| Haiku 4.5 | $0.00003 | $0.00020 |
Grade A, and why
engram-plugin-thin 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
When to Use
Use this skill when:
- Editing plugin hooks/scripts/adapters
- Adding passive/active memory capture integrations
- Wiring agent-specific setup behavior
Boundary Rules
- Keep adapters thin: parse input, call API/tool, return.
- Put complex logic in Go core (
store/server/mcp). - Avoid extra runtime dependencies in plugin scripts.
- Reuse a shared contract across all supported agents.
Compatibility Checklist
- Claude Code flow still works
- OpenCode flow still works
- Gemini/Codex config paths remain valid
- Docs reflect real integration behavior
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-plugin-thin is a skill published in the GitHub repository Gentleman-Programming/engram (6,232 stars, last pushed 2d ago), licensed MIT. It adds 32 tokens to every session and 201 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.
