Claude Prompt Drift Check

Detect drift in the Claude system prompt that agent-container sends to Anthropic. Captures two axes — the bare `claude_code` preset (Anthropic baseline) and agent-container's fully custom wire request — at the SDK version pinned in `agent-container/package-lock.json`, then stores versioned snapshots in `<skill>/snapshots/` (gitignored). Because SuperAgent REPLACES the preset with its own system prompt, preset drift never reaches our sessions automatically — every pure-claude change must be triaged for porting into system-prompt.md. Use when bumping `@anthropic-ai/claude-agent-sdk`, debugging unexpected model behavior after an SDK upgrade, previewing what a PR changes in the on-wire prompt, or auditing what Anthropic silently changed in the Claude Code preset.

What does this entry provide?

Claude Prompt Drift Check is an agent skill entry in ChatHome Skills, sourced from GitHub Skill Search and scored 58/100. # Claude Prompt Drift Check Capture + diff of the `/v1/messages` request body that `claude-agent-sdk` emits, at two layers: | Axis | What it captures | | ------. As an agent skill, it packages a reusable instruction set that AI coding agents such as Codex and Claude Code can load to perform this task without hand-written glue code. ChatHome Skills discovered this entry through its daily ingest of official registries and GitHub discovery queries, and re-verifies repository facts, freshness signals, and install metadata on every run. The quality score weighs official-registry presence, a working install command, license clarity, GitHub star trajectory, and repository freshness — the full formula is on the Sources page. The install command above is ready to copy. Review the last-pushed date and repository status before adding Claude Prompt Drift Check to a production agent workflow; the snapshot facts below are point-in-time values from the most recent ingest.

How is this score calculated?

Weighted across six dimensions, scored 0-100.
Provenance (25): listed in an official or curated registry.
Installability (25): a runnable install command beats a declared transport, which beats a source checkout.
Maintenance (20): recency of the last push; archived entries score zero here.
Adoption (20): repository stars on a log curve.

Security signals

Scan coverage: Install metadata and the indexed document body.

Automated signals from install metadata and a bounded skill body — not a full code security audit and not a recursive source or dependency review.
