ai-memory is a shared long-term memory system for coding agents that preserves project knowledge, unfinished work, failed approaches, and open questions across tools and machines. It is used by individual developers and teams to hand work between different coding agents and continue projects without repeating the context.
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.

SkillSpector: 3 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00061 | $0.00978 |
| Opus 5.5 | $0.00024 | $0.00391 |
| Sonnet 5.5 | $0.00012 | $0.00196 |
| Haiku 4.5 | $0.00006 | $0.00098 |
Grade A, and why
ai-memory-routing-install 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.
How it starts
The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ai-memory routing install
Use this skill when the user wants ai-memory's agent-facing routing instructions or managed Agent Skills installed, refreshed, repaired, or removed.
Tools in this cluster
memory_install_self_routingreturns the canonical markered instruction block, marker strings, filename hints, notes, and managed skill payloads for agents that cannot let the MCP server write the host filesystem directly. Passcompact: truewhen managed Agent Skills are installed or when refreshing a file that already uses the compact snippet.
Managed instruction marker
The always-loaded instruction block is owned by ai-memory only between these markers.
- Start marker:
<!-- ai-memory:start --> - End marker:
<!-- ai-memory:end -->
Refresh must replace the first complete marker-bounded block whose start and end delimiters appear alone on their own lines, preserving unrelated content before and after it. Ignore inline mentions of marker strings inside prose or code; they are not delimiters. If no complete line-delimited block exists, append the canonical block with one blank line of separation. Never edit unrelated instructions while refreshing ai-memory routing.
Managed skill marker
Every ai-memory-managed SKILL.md file contains this ownership marker.
<!-- ai-memory-managed: routing-skill -->
Installers and uninstallers should overwrite or remove same-name skill files only when that marker is present, unless the user supplied an explicit force option. If a same-name skill lacks the marker, skip it with an actionable message so user-authored skills are preserved.
Global Grok installs also write $GROK_HOME/rules/ai-memory-handoff.md (default ~/.grok/rules/ai-memory-handoff.md) with the ownership marker <!-- ai-memory-managed: grok-handoff-rule -->. Overwrite or uninstall that file only when the marker is present, unless the user supplied --force. Project-scope Grok skill installs leave that user rule alone.
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.

ai-memory-routing-install is a skill published in the GitHub repository akitaonrails/ai-memory (13,818 stars, last pushed today), licensed MIT. It adds 61 tokens to every session and 978 once invoked, about $0.0002 per session on Opus 5.5. 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.
