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 | $0.00038 | $0.00333 |
| Opus 5 | $0.00019 | $0.00167 |
| Sonnet 5 | $0.00008 | $0.00067 |
| Haiku 4.5 | $0.00004 | $0.00033 |
Grade A, and why
preserve 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 10d 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
Preserve
Archive artifact bundles intact under archive/.
When to use
- User says "preserve this", "archive this", "save these artifacts", or "move this to the vault archive"
- Generated handoff bundles, screenshots, logs, proofs, attachments, or other evidence packets
- Anything that should stay bundled rather than become atomic notes
Process
- Summarize what will be preserved and whether copy or move will be used.
- Copy by default. Only move when the user explicitly requests a destructive move.
- Prefer the
memento_preserveMCP tool when available. - Preserve into
archive/<slug>/with the source tree intact. - Write a manifest at
archive/<slug>/.memento/manifest.jsonand a lightweight index note atarchive/<slug>/.memento/index.md. - If a project can be detected, update the relevant project index with a link to the bundle index note.
- Include original source path, title, description, tags, cwd, branch, and session id when known.
- Warn if files look sensitive; do not silently redact the preserved bundle itself.
- After preserving, report the archive path and manifest path.
Rules
- Do not create atomic notes unless the user also asks for a summary note.
- Do not flatten the bundle into a prose summary.
- Never move by default.
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.

preserve is a skill published in the GitHub repository sandsower/memento-vault (12 stars, last pushed 26d ago), licensed MIT. It adds 38 tokens to every session and 333 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.
