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 | $0.00040 | $0.00510 |
| Opus 5 | $0.00020 | $0.00255 |
| Sonnet 5 | $0.00008 | $0.00102 |
| Haiku 4.5 | $0.00004 | $0.00051 |
Grade A, and why
write-agentmemory-skill 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 3d 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.
This is a copy
100% identical to write-agentmemory-skill — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 41 lines — stays where its author put it; the contents beside it link to each section on GitHub.
agentmemory skills follow one tiered format so they stay skimmable, accurate, and current. Match it exactly.

SKILL.md rules
- Frontmatter:
name,description, optionalargument-hint, anduser-invocable. Setuser-invocable: trueonly for skills the user runs as a slash command; reference and knowledge skills arefalse. - Description is two sentences and the only thing the agent sees when deciding to load the skill. Sentence one states the capability. Sentence two starts "Use when" and lists concrete triggers. Keep it distinct from sibling skills, under 1024 chars, third person.
- Body order: Quick start (one concrete example), Why (the governing principle), Workflow (numbered steps with decision gates), Anti-patterns (a WRONG vs RIGHT callout for the top mistake), Checklist, See also (cross-link siblings), Reference or Troubleshooting pointer.
- Stay under 100 lines. Move dense facts to REFERENCE.md and examples to EXAMPLES.md.
- Cross-references link one level deep only. Shared recovery steps live in
../_shared/TROUBLESHOOTING.md, never inlined.
Keep it current
Facts that exist in source (tool names and parameters, REST endpoints, env vars, connect adapters, hook events) are generated, never hand-typed. Edit the source, then run npm run skills:gen. CI runs npm run skills:check and fails on drift, so generated tables cannot fall behind the code.
Style
No external or competitor product names. No emojis. No em-dashes. No filler. State the thing and stop.
Checklist
- Description has a "Use when" sentence with real triggers.
- SKILL.md is under 100 lines.
- No time-sensitive claims and no duplicated troubleshooting block.
- Concrete example present; generated facts come from the generator.
- Cross-links resolve and go one level deep.
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.

write-agentmemory-skill is a skill published in the GitHub repository M-T-D-N/agentmemory-codex-windows (2 stars, last pushed 4d ago), licensed Apache-2.0. It adds 40 tokens to every session and 510 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to write-agentmemory-skill, differing in 0 lines, and is treated as a copy.
Other skills, from other repositories
engraphis-memory
Give the agent durable, scoped, explainable memory across sessions and repositories through the Engraphis MCP tools. Use when you learn a convention, decision, bug cause/fix, or user preference worth keeping; when prior context would help before you answer or act (to avoid re-asking or re-deriving); when asked "why is…
talamus-memory
Set up and use Talamus as durable, local-first memory for AI agents. Use when an agent needs to initialize or diagnose a Talamus brain, ingest files or repositories, retrieve cited context across sessions, inspect note history, verify memory against sources, review proposed corrections, connect Talamus through MCP, or…
shodh-memory
Persistent memory system for AI agents. Use this skill to remember context across conversations, recall relevant information, and build long-term knowledge. Activate when you need to store decisions, learnings, errors, or context that should persist beyond the current session.
plur-memory
Persistent learning for AI agents. Open engram format. Your agent learns from corrections, remembers across sessions, and transfers knowledge across domains.
lemmalog
Externalize working memory and logical state into the lemmalog Datalog engine (MCP). Use for ANY multi-step task where state should outlive one context window or span agents: long investigations, debugging sessions, audits, multi-agent searches, systematic explorations, planning with many interdependent constraints…
ori-memory
Persistent agent memory with learning retrieval. Knowledge graph on markdown files — capture insights, decisions, research, and learnings during work, then retrieve them weeks or months later. Use when knowledge is too valuable to lose but too much to inject into every prompt.
