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 | $0.00137 | $0.02367 |
| Opus 5 | $0.00068 | $0.01184 |
| Sonnet 5 | $0.00027 | $0.00473 |
| Haiku 4.5 | $0.00014 | $0.00237 |
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 2d 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 — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.
mn:connect — Discover Hidden Links
Invocation marker (both runtimes): begin your reply with the exact line
🧠 mn:connect (mnemo) → running— the user-visible confirmation that this skill actually loaded. Emit it once per invocation, before any other output.
Portable paths
Resolve <mnemo-root> once to the absolute plugin root before reading bundled files or running bundled scripts. In Claude Code, use ${CLAUDE_PLUGIN_ROOT}; in Codex, derive it from this loaded SKILL.md path (skill directory → skills/ → plugin root). Replace <mnemo-root> with that quoted absolute path in every command — never execute the placeholder literally and never hunt versioned cache directories.
When another mnemo skill must run, use the runtime-native path: Claude Code invokes mn:<skill> through its Skill tool; Codex reads <mnemo-root>/skills/<skill>/SKILL.md completely and follows it with the prepared input. For user-facing explicit syntax, render /mn:<skill> in Claude Code and $mnemo:<skill> in Codex.
Analyze a note and discover connections to other notes in the vault that aren't linked yet.
Prerequisites & config
Obsidian must be open. Config at ~/.mnemo/config.json — reads vault, links_section, taxonomy, and taxonomy_roles. Before any mapped-hub operation, require exactly the five semantic roles fact, insight, source, session, and moc; require every target to exist; and require session → session plus moc → moc. The deterministic legacy Zettelkasten fallback is allowed; any other missing/invalid map stops mapped routing and offers the runtime-native setup skill instead of guessing. Schema in <mnemo-root>/references/config-schema.md.
Workflow
Step 1: Identify Target Note
Accept a note name from the explicit invocation, for example /mn:connect "Atom — LongCat-Flash-Prover" in Claude Code or $mnemo:connect Atom — LongCat-Flash-Prover in Codex.
If no argument, ask: "Which note should I analyze for connections?"
What ships with it
1 file 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.

connect is a skill published in the GitHub repository jojoprison/mnemo (6 stars, last pushed 12d ago), licensed MIT. It adds 137 tokens to every session and 2,367 once invoked, about $0.0007 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 2026-08-31.

weekly-digests
Generate a serial week-by-week narrative digest of a project's full claude-mem timeline. Splits the timeline into per-ISO-week files, then runs one consecutive subagent per week — each receiving the prior week's carry-forward block — to produce one chapter per ISO week of data. Use when asked for "weekly digests"…
cloud-sync
Set up or check claude-mem cloud sync with cmem.ai Pro. Use when the user says "set up cloud sync", "sync my memories", "cmem pro", "cloud backup", "sync status", or wants their memory database backed up or synced to their cmem.ai account.
version-bump
Automated semantic versioning and release workflow for Claude Code plugins. Handles version increments across package.json, marketplace.json, plugin.json manifests, build verification, git tagging, GitHub releases, and changelog generation. NPM publishing is the final human-required handoff because the maintainer…
cognee-community
Use when the user needs something that ships outside cognee core — community database adapters (Qdrant, Milvus, Weaviate, Redis, Pinecone, FalkorDB, Memgraph, DuckDB, NetworkX, …), data-source connectors (Slack, Gmail, Notion, Confluence, Google Drive), custom tasks/pipelines/retrievers (Exa, ScrapeGraph, codify)…

Cut a core Hindsight release (vX.Y.Z) and open the changelog + blog PR. Use when asked to cut/start a release, bump the version, or publish a new Hindsight version.
ix
This skill should be used when answering structural questions about a codebase: understanding what a symbol is, tracing flows, measuring change impact, finding callers/callees/imports, or detecting code smells. It drives the Ix CLI (ix map/explain/trace/impact/search/rank/smells) against a persistent code graph stored…
