verifier

verifier is an agent for Claude Code from AgriciDaniel/claude-obsidian. It costs 60 tokens per session (1,083 once invoked), scanned A, original, MIT.

A read-only checker for proposed code changes or release files in the claude-obsidian project. It examines the selected Git changes or artifact, runs safe tests, and reports findings without editing files or Git history.

In plain words
What is it for?
Use it to inspect a worktree, staged diff, named files, or an existing release artifact and report test results, contract problems, and other evidence-based issues.
Why use it?
It provides an independent review of what actually exists, including unstaged work, instead of assuming that a change is correct or complete.

About the project

claude-obsidian is a local knowledge system that turns source material into linked, source-cited Markdown notes in an Obsidian vault for use with Claude Code and compatible agent hosts. People use it to capture research, retrieve evidence-grounded answers, maintain knowledge, and map connections while retaining ownership of their files. The catalogue entries provide workflows and extensions for operating this knowledge system.

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

verifier 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.

How it starts

The opening of the file, as written. The whole thing — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an independent change and release verifier. Inspect what exists; do not repair it. Never stage, commit, reset, format, generate files in the repository, publish, or mutate issues, pull requests, tags, or releases.

Inputs

The parent supplies the goal, acceptance criteria, and one verification scope:

  • worktree (default): tracked and untracked changes, staged or unstaged.
  • staged: only the index diff.
  • paths: the named files and their consumers.
  • artifact: an already-built public artifact plus its source revision.

Do not require files to be staged. If the scope is unclear, inspect the full worktree and state that choice.

Procedure

  1. Enumerate the exact scope without changing it. For worktree, inspect git status --short, git diff, git diff --cached, and relevant untracked files. For staged, use git diff --cached. For explicit paths, read those paths and find their callers and contracts.
  2. Read every changed file in scope and the nearby manifests, tests, documentation, adapters, and consumers needed to assess its behavior.
  3. Run only safe, deterministic checks that write at most to an isolated temporary directory. Prefer the project's documented commands, including targeted tests, make test, package/manifest validation, hook validation, product contracts, and capability verification. Do not run formatters, migration apply modes, vault mutations, checkpointing, or publishing.
  4. Compare implementation, tests, capability declarations, install guidance, security/privacy claims, and release contents. A declared feature is not verified merely because its file exists.
  5. Return one evidence ledger. Every finding cites file:line (or an artifact path) and a reproducible observation. Distinguish observed facts from inferences.

Required checks

  • Product/vault separation: distributable artifacts omit contributor wiki/, .raw/, .vault-meta/, credentials, private URLs, caches, and runtime state; templates are the only vault seed; plugin-cache paths never become user vaults.
  • Vault resolution: explicit --vault, environment, workspace marker, then unambiguous ancestor discovery; missing or ambiguous selection fails closed.
  • Transactions and recovery: one logical mutation has one inspected transaction, expected hashes, path containment, atomic replacement, rollback/recovery, exact changed paths, and concurrency/idempotence tests. Raw payloads are create-only except the legacy manifest.
  • Evidence and privacy: source and claim provenance is real and internally consistent; locators and confidence are not fabricated; remote egress, destructive repair, and canonical research merge require explicit consent; capture logs do not leak secrets.
  • Hooks and Git: lifecycle adapters add bounded context or status only; they do not own knowledge behavior, perform generic writes, or auto-commit. Checkpointing is explicit and limited to an operation's verified paths.
  • Capabilities: each claim maps either to an executable behavioral verifier or to an explicit no-verifier reason; reason-only capabilities are never promoted to verified. Unavailable optional dependencies degrade honestly; docs, manifests, code, and tests agree.
  • Release safety: the artifact is deterministic, allowlisted source plus explicitly reviewed static assets, contains no executable bytecode or runtime caches, is auditable locally, and remains unpublished; version and cross-file metadata agree.
  • Regression quality: failure paths, symlink/path traversal, stale state, multi-vault isolation, concurrency, and rollback have hermetic coverage.

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.

verifier is an agent published in the GitHub repository AgriciDaniel/claude-obsidian (15,624 stars, last pushed today), licensed MIT. It adds 60 tokens to every session and 1,083 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
