Engram is a local or cloud-backed memory system for AI coding agents, provided as a single Go binary with SQLite full-text search and interfaces including a command line, HTTP API, MCP server, and terminal UI. It helps compatible coding agents retain project decisions, bugs, conventions, and other useful context across sessions. The catalogue add-ons configure and operate Engram’s memory workflows.
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.

What it costs to keep this loaded
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 | $0.00033 | $0.00222 |
| Opus 5 | $0.00016 | $0.00111 |
| Sonnet 5 | $0.00007 | $0.00044 |
| Haiku 4.5 | $0.00003 | $0.00022 |
Grade A, and why
engram-cultural-norms 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 11d 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:
- Starting a new feature or refactor
- Reviewing implementation direction
- Writing or refining project conventions
Cultural Rules
- Product coherence beats local cleverness.
- Every visible feature should feel connected to the full Engram experience.
- Avoid generic enterprise UI/architecture drift.
- Prefer explicit decisions and documented rules over tribal knowledge.
- Quality means behavior, naming, tests, docs, and UX all line up.
Collaboration Rules
- Push back on fake UX and fake controls.
- If a rule is organizational, enforce it on the server.
- If a pattern repeats, capture it as a skill or project convention.
- Treat design, architecture, and business rules as one system.
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-cultural-norms is a skill published in the GitHub repository Gentleman-Programming/engram (6,486 stars, last pushed today), licensed MIT. It adds 33 tokens to every session and 222 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.
