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 | $0.00032 | $0.01557 |
| Opus 5.5 | $0.00013 | $0.00623 |
| Sonnet 5.5 | $0.00006 | $0.00311 |
| Haiku 4.5 | $0.00003 | $0.00156 |
Grade A, and why
connect 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/connect
Intent. Take a note that exists but is poorly connected, and integrate it into the graph. Add inline [[wikilinks]] in its body where genuine connections exist; add inverse links from connected notes back to it; update MOC membership both ways.
When to invoke
- Just after
/extract(composed by/learn) - When you realise an old claim should link to newly-added work (use
--bulkwith a date-filtered glob) - When
/auditflags a note as orphaned
Behaviour
Forward pass — add links from this note to others
- Read the target note: title, description, frontmatter, body.
- Discover candidates via two channels in parallel:
- Semantic search:
qmd querywithintent= the note's description, typeslexandvec. Return top ~30 candidates. - Frontmatter walk: read the note's
tags,methods,topics,supports,contradictsarrays. Walk those notes; collect their tags + neighbours (one hop).
- Semantic search:
- Filter candidates. A connection is genuine when:
- The target note's claim requires, follows from, qualifies, contradicts, or exemplifies the candidate
- Or: the candidate is a method used in the target's evidence chain
- Or: the candidate is a paper sourcing the target
- Not genuine: "they share a topic", "they sound related", "they were co-extracted from the same source" (sibling-only)
- Add inline
[[wikilinks]]in the body where genuine connections fit, with surrounding prose explaining the relationship. Avoid bare-link lists — context phrases prefix every link. - Update structured frontmatter where the connection has a typed slot:
supports,contradicts,methodsarrays gain entries.
Backward pass — add links from others to this note
- For each connected note from step 4: read it. Decide whether the inverse link belongs in its body. If yes, add it (with surrounding prose).
- Update structured frontmatter on the connected notes if applicable (e.g. paper notes get the new claim in their
claims:list — though/extractmay have done this already).
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.

connect is a skill published in the GitHub repository letrplB/second-brain (1 stars, last pushed 5mo ago), licensed MIT. It adds 32 tokens to every session and 1,557 once invoked, about $0.0001 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.

shodh-memory
Persistent memory system for AI agents. Use this skill to remember context across conversations, recall relevant information, and build long-term knowledge. Activate when you need to store decisions, learnings, errors, or context that should persist beyond the current session.
curate
Power-user audit of Wenlan's pending surfaces: accept or dismiss pending revisions (conflicts/merges), or audit pending captures (not yet confirmed). Most users want /brief for revisions; that handles the daily flow. Use /wenlan curate only for explicit deep-walk audits after bulk imports, or to walk the full queue…
pages
Browse, open, or print distilled pages, reusing the wenlan pages CLI for the actual open (one implementation on your PATH, no setup). /wenlan pages opens the page when one matches, or shows a small native picker when 2-4 match. /wenlan pages --print reads the page here instead of opening an editor. /wenlan pages lists…
forget
Delete a memory from Wenlan by ID. Destructive and cannot be undone — prefer /capture with supersedes for corrections. Invoked as /wenlan forget .
llm-wiki
Build and maintain an LLM-curated knowledge base from papers, articles, transcripts, notes and project findings. Ingest sources into linked Markdown, answer questions with citations, lint or upgrade a wiki, and preserve useful synthesis across sessions and agents. Also capture verified task experience, consolidate…
raytsystem-save
Stage a cited synthesis as a typed raytsystem DRAFT bundle and escaped preview. Use for SAVE, preserving a verified query answer, preparing a knowledge proposal, or creating a reviewable draft; never treat SAVE as canonical promotion or publication.
