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 | $0.00128 | $0.05078 |
| Opus 5 | $0.00064 | $0.02539 |
| Sonnet 5 | $0.00026 | $0.01016 |
| Haiku 4.5 | $0.00013 | $0.00508 |
Grade A, and why
ax-agent-memory-skills 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 5d 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
97% identical to ax-agent-memory-skills — 2 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.

AxAgent Memory And Skills Rules (@ax-llm/ax)
Use this skill when an agent needs a persistent context map, task-relevant memory retrieval, or skill guides loaded into the executor prompt on demand. For ordinary agent setup use ax-agent. For RLM runtime policy use ax-agent-rlm. For callbacks and telemetry use ax-agent-observability.
Use These Defaults
- Use a static
skillsCatalog/memoriesCatalogwhen the skill guides or memories fit in a plain array — Ax then backsdiscover({ skills })/recall(...)with a built-in deterministic local search and no host search code is needed. - Use
onSkillsSearch/onMemoriesSearchwhen retrieval needs a real backend (vector DB, BM25 service, KV). A host callback always takes precedence over the catalog's built-in search. - Use
contextMapwhen repeated runs inspect the same long external context and should accumulate a small orientation cache automatically. recall(...)is available to distiller and executor stages whenonMemoriesSearchor a non-emptymemoriesCatalogis set.discover({ skills })is available to the executor whenonSkillsSearchor a non-emptyskillsCatalogis set.- With
skillsCatalog, the executor prompt also gains a static### Available Skillsindex (id + name + description), so skill discovery is targeted instead of blind. - Both
recall(...)anddiscover({ skills })returnvoid. The loaded content appears on the next turn. - Use
onLoadedMemories/onLoadedSkillsto observe what got loaded. - Use
onUsedMemories/onUsedSkillsto track what the actor says it actually relied on. - Child agents do not inherit memory or skills search callbacks; wire them explicitly on every agent that needs the capability.
Context Map
Use contextMap when repeated runs ask different questions over the same long context, document set, or repository. The map is prompt-resident orientation knowledge: structure, concepts, constants, parsing schema, reusable aggregate results, and concrete error patterns. It is not a task-specific answer cache.
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.

ax-agent-memory-skills is a skill published in the GitHub repository dosco/aithy (107 stars, last pushed 8d ago), licensed Apache-2.0. It adds 128 tokens to every session and 5,078 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. It is 97% identical to ax-agent-memory-skills, differing in 2 lines, and is treated as a copy.
Other skills, from other repositories
onboarding
Set up your Personal OS in 15 minutes through a conversational interview. Creates SOUL.md, USER.md, IDENTITY.md, AGENTS.md, and MEMORY.md — the foundation files your agent reads every session.
recall
Load context from past sessions. Three modes: temporal (what did I work on yesterday/last week), topic (semantic search across sessions and notes), and graph (visual map of session-file relationships). Every recall ends with One Thing — the single highest-leverage next action.
mem0-vercel-ai-sdk
Mem0 provider for Vercel AI SDK (@mem0/vercel-ai-provider). TRIGGER when: user mentions "vercel ai sdk", "@mem0/vercel-ai-provider", "createMem0", "retrieveMemories", "addMemories", "getMemories", "searchMemories", "mem0 vercel", "AI SDK provider", "AI SDK memory", or is using generateText/streamText with mem0. Also…
mem0-tour
Browses all stored memories grouped by category with full content display. Use when reviewing all project memories, exploring stored knowledge, onboarding to a project, or getting an overview of captured decisions, conventions, and learnings.
pause
Pause Mem0 memory capture on this machine. Use when the user wants to stop memories being recorded, for example for private work or experiments.
mine
Mine a project or conversation into your MemPalace — extract and store memories for later retrieval.
