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 | $0.00044 | $0.00903 |
| Opus 5 | $0.00022 | $0.00451 |
| Sonnet 5 | $0.00009 | $0.00181 |
| Haiku 4.5 | $0.00004 | $0.00090 |
Grade A, and why
obsidian-mcp 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 7d 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 — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Constraints
- NO write without fresh read first
- NO completion claims without readback verification
- EVERY changed line must trace to user request
- This skill owns vault operations ONLY; workflow decisions belong to companion skills
Host Constraints (version-locked — re-verify on upgrade)
These are based on [email protected]. They may be stale.
To re-verify: call the forbidden API with a trivial test payload. If it returns -32602, constraint holds. If it succeeds, update this table and remove the ban.
| Operation | Status | Alternative |
|---|---|---|
obsidian_patch_note |
Forbidden (last verified: 2026-05-10) | obsidian_replace_in_note |
obsidian_append_to_note |
Forbidden (last verified: 2026-05-10) | obsidian_replace_in_note or obsidian_write_note overwrite:false for new files |
obsidian_write_note overwrite:true |
Forbidden by default | Surgical replace for existing files |
obsidian_delete_note |
Requires user confirmation | List path + risk first |
If you suspect a constraint is stale, test it. A successful call means the ban should be lifted.
Tool Selection
| Goal | Tool |
|---|---|
| Browse structure | obsidian_list_notes (depth 2-4) |
| Search | obsidian_search_notes |
| Read before edit | obsidian_get_note format:"document-map" then content/full |
| Create note | obsidian_write_note overwrite:false → readback |
| Edit existing | obsidian_replace_in_note → readback |
| Frontmatter | obsidian_manage_frontmatter |
| Tags | obsidian_manage_tags |
When selecting tools, read references/examples.md for operation patterns.
Workflow
- Locate: identify targets, read before writing
- Plan: minimum change only; report unrelated issues, don't fix them
- Write: use appropriate tool from table above
- Verify: readback every write; compare actual vs expected
When formatting completion reports, read references/templates.md.
Error Recovery
What ships with it
5 files 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-mcp is a skill published in the GitHub repository r007b34r/opencode-obsidian-knowledge-workflow (11 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 44 tokens to every session and 903 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 2026-08-31.

project
Create or maintain an Architecture Studio project — initialize its record bundle, remember sourced facts, capture or supersede decisions, inspect project status, or migrate a 1.x PROJECT.md. Use when the user says “set up the project,” “remember this,” “we decided,” asks about project context, or runs /as:project.
llm-wiki
Build and maintain an LLM-curated personal knowledge base — the "LLM Wiki" pattern from Andrej Karpathy's April 2026 gist. Use this skill whenever the user wants to ingest a source (paper, article, transcript, PDF, notes) into a persistent compounding knowledge base, ask a question against accumulated notes, lint or…
orient
Use when user invokes /orient with a topic keyword, entity type, project name, time qualifier, or combination. Also triggers on "what do we know about X", "remind me about X", "where did we leave off on X". Provides targeted context loading — searches the MCP Memory Server graph, knowledge files, journal entries, and…
memory
Use when user invokes /memory with a subcommand (search, trace, add, episode, status). Also triggers on "search my memory for X", "add to memory", "what do I know about X" (when membrain is available), "memory status", "memory trace". Searches and manages the membrain knowledge graph via MCP tools or HTTP API.
capture
Use when user invokes /capture to capture information from the current conversation into a staging file for later reflection and knowledge graph processing. Accepts no arguments (auto-extract), specific facts as text, or filter keywords like "decisions" or "technical". Do NOT use when the user wants to write directly…
cc-wiki
Distill the user's /.claude history into a Quartz knowledge base. Runs preprocess.py, dispatches parallel project-digest agents, then parallel cross-cutting synthesis agents (people / companies / projects / concepts / workflows / tools / playbooks), writes the spine, installs Quartz, and starts the dev server. Single…
