obsidian is a skill for Claude Code, Codex from dodo-reach/hermes-link-curator. It costs 13 tokens per session (2,875 once invoked), scanned A, original, MIT.

A filing workflow for a local Obsidian vault, which is a folder of linked notes. It saves URLs as organized entries rather than summarizing them in chat.

In plain words
What is it for?
Use it when you send a URL or ask to save or archive something in the vault.
Why use it?
It keeps saved links in one consistent place and format, making the vault easier to maintain.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

obsidian scanned grade A with 1 finding 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 12d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/rebuild_index.py, scripts/save_entry.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 237 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Behavior — do not summarize, archive

When the user sends a URL or asks to save/archive something: archive it immediately, do not summarize. Your job is that of a librarian: receive → process → file. Not a chatbot to give impressions.

Do NOT respond with a summary of the content unless the user explicitly asks for one. Archive first, then say only "Salvato." (or the error, if any).

Entry format

### [Title]
- **URL**: https://...
- **Type**: `github` | `x-post` | `article` | `tool` | `video` | `paper` | `other`
- **Tags**: #tag1 #tag2 #tag3
- **Added**: YYYY-MM-DD
- **Summary**: What is this? Why does it matter? What do you do with it?

---

[next entry]

--- between every entry. No --- = merged entry in dashboard. Parse splits on \n---\n.

Save workflow

Use save_entry.py — atomic read+patch, never overwrites INDEX.md.

python3 <profile-dir>/skills/note-taking/obsidian/scripts/save_entry.py \
  --url "https://..." \
  --title "Entry Title" \
  --type "article" \
  --tags "ai dev-tools" \
  --added "2026-06-04" \
  --summary "What it is and why it matters."

The script:

  1. Reads INDEX.md in memory (never overwrites without reading)
  2. Finds the first --- separator
  3. Inserts the new entry AFTER the first --- separator (each entry gets its own chunk)
  4. Also appends to the daily note vault/YYYY-MM-DD.md
  5. Runs validate.py automatically

⚠️ Prepend bug (fixed): Old versions of save_entry.py inserted new entries BETWEEN the header and the first ---. When two entries from the same day were saved consecutively, they ended up in the same chunk. The dashboard parser uses re.findall(r'\*\*URL\*\*', chunk)[0] — only the first URL per chunk was read. Symptoms: entry appears in INDEX.md but not in dashboard (or dashboard shows fewer entries than vault count). Fix was to change lines[:sep_idx]lines[:sep_idx+1] so insertion happens AFTER the separator, not before. Run rebuild_index.py to fix retroactively affected vaults.

Files

What ships with it

2 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.

Changes

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.
