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 | $0.00108 | $0.00913 |
| Opus 5 | $0.00054 | $0.00456 |
| Sonnet 5 | $0.00022 | $0.00183 |
| Haiku 4.5 | $0.00011 | $0.00091 |
Grade A, and why
save 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 6d 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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
save: File Conversations Into the Wiki
Good answers and insights shouldn't disappear into chat history. This skill takes what was just discussed and files it as a permanent wiki page.
The wiki compounds. Save often.
Note Type Decision
Determine the best type from the conversation content:
| Type | Folder | Use when |
|---|---|---|
| synthesis | wiki/questions/ | Multi-step analysis, comparison, or answer to a specific question |
| concept | wiki/concepts/ | Explaining or defining an idea, pattern, or framework |
| source | wiki/sources/ | Summary of external material discussed in the session |
| decision | wiki/meta/ | Architectural, project, or strategic decision that was made |
| session | wiki/meta/ | Full session summary: captures everything discussed |
If the user specifies a type, use that. If not, pick the best fit based on the content. When in doubt, use synthesis.
Save Workflow
- Scan the current conversation. Identify the most valuable content to preserve.
- Ask (if not already named): "What should I call this note?" Keep the name short and descriptive.
- Determine note type using the table above.
- Extract all relevant content from the conversation. Rewrite it in declarative present tense (not "the user asked" but the actual content itself).
- Create the note in the correct folder with full frontmatter.
- Collect links: identify any wiki pages mentioned in the conversation. Add them to
relatedin frontmatter. - Update
wiki/index.md. Add the new entry at the top of the relevant section. - Append to
wiki/log.md. New entry at the TOP:## [YYYY-MM-DD] save | Note Title - Type: [note type] - Location: wiki/[folder]/Note Title.md - From: conversation on [brief topic description] - Update
wiki/hot.mdto reflect the new addition. - Confirm: "Saved as [[Note Title]] in wiki/[folder]/."

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.

save is a skill published in the GitHub repository zhaixin244-wq/fnw (29 stars, last pushed 3mo ago), licensed MIT. It adds 108 tokens to every session and 913 once invoked, about $0.0005 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 2026-09-03.
