What is obsidian-git-sync-mcp CLAUDE.md?

Repository instructions for the Obsidian Git Sync MCP project, covering its commands, change process, testing, deployment, and known details. It is guidance for Claude Code working in that repository, not a general-purpose integration.

Following the repository’s test command, preparing changes through its OpenSpec process, understanding container builds, and avoiding documented project mistakes.

It gives an agent the project-specific rules needed to make changes safely and run the correct tests and workflow.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00523	$0.00523
Opus 5.5	$0.00209	$0.00209
Sonnet 5.5	$0.00105	$0.00105
Haiku 4.5	$0.00052	$0.00052

Security

Grade A, and why

obsidian-git-sync-mcp CLAUDE.md 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.

What it actually says

CLAUDE.md

Operational notes for this repo. Project thesis, tech stack, and deployment live in openspec/config.yaml (context block) and README.md — don't duplicate them here.

Commands

Test: uv run --extra dev python -m pytest (bare pytest / uv run pytest fail — needs the dev extra + python -m)
The two images build via .github/workflows/build-containers.yml on push to main/v* tags → ghcr.io/jjsmackay/obsidian-mcp and …/obsidian-sync.

Change workflow

Spec-driven via OpenSpec: propose changes with /opsx:propose, not ad-hoc edits.
Full cycle: /opsx:propose → commit → /opsx:apply → /opsx:archive → commit. /opsx:propose STOPS at "ready for apply" (generates artifacts, doesn't apply/archive) — continue explicitly.
Branch → PR → squash-merge. Never commit directly to main. One branch per change, named <slug>. On it, two commits: docs(openspec): propose <slug>, then the impl commit (feat(...)/docs(...)) that folds in opsx:archive (spec sync + move to openspec/changes/archive/).
The squash commit is what lands on main: title it like the impl commit (conventional-commit form), body summarising the why. Open the PR with gh pr create; merge with gh pr merge --squash.
openspec archive stamps the archive dir with the host clock (often a day off) — rename the dir to the real date to match siblings.
Validator quirk: only a requirement's first line is checked for SHALL/MUST; no backticks in requirement headers.
.claude/ is gitignored; regenerate slash commands with openspec init --tools claude.

Gotchas

VAULT_GIT_ENABLED=true makes the mcp container fail-closed at startup if the vault isn't a git working tree or the remote is missing (config.py:validate_gitsync).
obsidian-web-mcp is consumed as base image + Python dependency; contribute changes upstream, don't fork.

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.
