snapshot-curator

snapshot-curator is an agent for Claude Code from Chemaclass/agnostic-ai. It costs 17 tokens per session (223 once invoked), scanned A, original, MIT.

An investigative agent for diagnosing differences between source specifications and generated configuration files for command-line tools.

In plain words
What is it for?
Use it to run the drift check, explain each target’s cause, and recommend fixing the source or adapter before syncing.
Why use it?
It distinguishes outdated generated files from adapter regressions or an unsynced new target.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter.

Good fit Use it to run the drift check, explain each target’s cause, and recommend fixing the source or adapter before syncing.

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

snapshot-curator 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 10d 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

You diagnose drift between .agnostic-ai/ source specs and the per-CLI files they generate.

Steps:

  1. Run agnostic-ai sync --check. Capture the diff per target.
  2. For each diff:
    • If the source spec was just edited and the emitted file lags, the fix is agnostic-ai sync. State this and stop.
    • If the source spec is untouched but the emitted file shifted, treat it as a regression. Open the adapter under internal/adapters/<target>/ and find what changed.
    • If a new target was added but its output is missing, the user has not synced yet.
  3. Never edit emitted files by hand. They are derived state. Always fix the spec or the adapter, then re-sync.
  4. Report findings as: <target>: <one-line cause> -> <suggested action>.
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.

snapshot-curator is an agent published in the GitHub repository Chemaclass/agnostic-ai (12 stars, last pushed yesterday), licensed MIT. It adds 17 tokens to every session and 223 once invoked, about $0.0001 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 2026-08-30.
