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 | $0.00080 | $0.00617 |
| Opus 5 | $0.00040 | $0.00309 |
| Sonnet 5 | $0.00016 | $0.00123 |
| Haiku 4.5 | $0.00008 | $0.00062 |
Grade A, and why
obsidian-knowledge-retrieval 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 11d 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 — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Obsidian Knowledge Retrieval
Answer from the user's live Obsidian knowledge base without changing it.
Routing
- Make this primary for pure search, recall, comparison, and synthesis.
- Let
method-training-coachlead when history is needed to continue an active exercise; use retrieval internally without revealing an old solution prematurely. - Let
obsidian-note-maintenancelead a focused write anddaily-knowledge-ingestlead a heterogeneous batch. - Let
method-evidence-reviewlead explicit evidence, practice-count, transfer, or readiness judgments. - Honor “read only” literally, even when a note appears outdated.
- If intent remains materially ambiguous, stay read-only and ask one concise question.
Tools
search_notes(query, maxResults)— locate relevant notes and snippets.read_note(path)— read a materially relevant Markdown note.list_notes()— browse structure only when necessary.ping()— troubleshoot connectivity only.
Workflow
- Start ordinary topic retrieval with
search_notes. - Inspect paths and snippets.
- Refine with synonyms, project terms, technical terms, or related concepts when needed.
- Read only strong candidates.
- Answer from actual note contents.
- Distinguish explicit note facts, cross-note synthesis, and unsupported inference.
Do not conclude that nothing exists after one failed query. Use list_notes only when the user asks to browse, no useful search term exists, or overall structure is necessary.
Factual fidelity and conflicts
- Preserve differing stages, dates, and conclusions.
- Identify conflicts instead of silently merging them.
- State which record is newer when dates support that conclusion.
- Use live notes rather than model memory.
- Do not infer a method level, practice count, or attribution from retrieved text unless the request is explicitly routed to Evidence Review.
Read-only boundary
Do not create, modify, delete, move, rename, append, preview writes, control training intensity, or claim a write occurred.
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.

obsidian-knowledge-retrieval is a skill published in the GitHub repository li1-user/obsidian-mcp-bridge (0 stars, last pushed 1mo ago), licensed MIT. It adds 80 tokens to every session and 617 once invoked, about $0.0004 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.

mem0-oss-to-platform
Plan and then execute a migration of a project from the mem0 open-source / self-hosted SDK (the local Memory class) to the mem0 Platform / hosted / managed SDK (the MemoryClient class). Use this whenever a developer wants to move, switch, or migrate their mem0 usage off OSS/self-hosted to the hosted API — e.g.…
