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 | $0.00042 | $0.01549 |
| Opus 5 | $0.00021 | $0.00775 |
| Sonnet 5 | $0.00008 | $0.00310 |
| Haiku 4.5 | $0.00004 | $0.00155 |
Grade A, and why
mem-search 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 8d 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 — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Memory Search
Search past work across all sessions. Simple workflow: search -> filter -> fetch.
When to Use
Use when users ask about PREVIOUS sessions (not current conversation):
- "Did we already fix this?"
- "How did we solve X last time?"
- "What happened last week?"
3-Layer Workflow (ALWAYS Follow)
NEVER fetch full details without filtering first. 10x token savings.
Step 1: Search - Get Index with IDs
Use the search MCP tool:
search(query="authentication", limit=20, project="my-project")
Returns: Table with IDs, timestamps, types, titles (~50-100 tokens/result)
| ID | Time | T | Title | Read |
|----|------|---|-------|------|
| #11131 | 3:48 PM | 🟣 | Added JWT authentication | ~75 |
| #10942 | 2:15 PM | 🔴 | Fixed auth token expiration | ~50 |
Parameters:
query(string) - Search termlimit(number) - Max results, default 20, max 100project(string) - Project name filtertype(string, optional) - "observations", "sessions", or "prompts"obs_type(string, optional) - Comma-separated: bugfix, feature, decision, discovery, changedateStart(string, optional) - YYYY-MM-DD or epoch msdateEnd(string, optional) - YYYY-MM-DD or epoch msoffset(number, optional) - Skip N resultsorderBy(string, optional) - "date_desc" (default), "date_asc", "relevance"
Step 2: Timeline - Get Context Around Interesting Results
Use the timeline MCP tool:
timeline(anchor=11131, depth_before=3, depth_after=3, project="my-project")
Or find anchor automatically from query:
timeline(query="authentication", depth_before=3, depth_after=3, project="my-project")
Returns: depth_before + 1 + depth_after items in chronological order with observations, sessions, and prompts interleaved around the anchor.
Parameters:
anchor(number, optional) - Observation ID to center aroundquery(string, optional) - Find anchor automatically if anchor not provideddepth_before(number, optional) - Items before anchor, default 5, max 20depth_after(number, optional) - Items after anchor, default 5, max 20project(string) - Project name filter
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.

mem-search is a skill published in the GitHub repository zhaixin244-wq/fnw (29 stars, last pushed 3mo ago), licensed MIT. It adds 42 tokens to every session and 1,549 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 2026-09-03.
