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 5.1 | $0.00058 | $0.01334 |
| Opus 5.5 | $0.00023 | $0.00534 |
| Sonnet 5.5 | $0.00012 | $0.00267 |
| Haiku 4.5 | $0.00006 | $0.00133 |
Grade A, and why
memento 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 1mo 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 — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.
memento - Code Assistant Memory Sync
When To Use
- The user switches between Claude Code, Codex CLI, Gemini CLI, Antigravity, Cursor, or Windsurf.
- The user wants to move memory, rules, skills, or
AGENTS.md-style instructions from one assistant to another. - The user wants to manage global memory such as
~/.claude/CLAUDE.md,~/.codex/AGENTS.md, or~/.gemini/GEMINI.md. - The user wants to inspect, clean up, consolidate, or prepare memory before syncing.

What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

memento is a skill published in the GitHub repository dandacompany/memento (8 stars, last pushed 5mo ago), licensed MIT. It adds 58 tokens to every session and 1,334 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 2026-08-31.
