verify

A command for checking the integrity of a ForgeProof .rpack provenance bundle. It verifies whether the recorded AI-generated code evidence has been altered since signing.

In plain words
What is it for?
Use it to find or specify an .rpack file and verify it, optionally using strict checks or a separate project directory.
Why use it?
It helps confirm that a bundle's evidence and cryptographic record are still trustworthy.

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

verify 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 yesterday.

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.

ForgeProof Verify: Bundle Integrity Check

Verify the cryptographic integrity of a ForgeProof .rpack provenance bundle.

The provenance engine script is at ${CLAUDE_PLUGIN_ROOT}/skills/run/scripts/forgeproof.py (referenced as $FP below). Determine the Python interpreter once: run python3 --version; if that fails or reports Python is not found, use python. Set $FP_PY to whichever succeeded. The examples use bash syntax; if your shell is PowerShell, adapt the invocation (& $FP_PY $FP ...).

Step 1 — Locate the bundle

If $ARGUMENTS contains a path, use it directly.

If $ARGUMENTS is empty, look for .rpack files:

ls .forgeproof/*.rpack 2>/dev/null

If multiple bundles exist, list them and ask the user which to verify. If none exist, tell the user no bundles were found.

Step 2 — Run verification

Default invocation:

"$FP_PY" "$FP" verify --rpack <path>

Add flags when the situation calls for them:

  • --strict — use when verifying in the origin repo or in CI, where all evidence should be present: a missing chain or missing artifacts become failures instead of warnings.
  • --project-root <dir> — use when the bundle sits outside the project layout (by default verify anchors artifact paths to the bundle's location, falling back to the current directory).
  • --format markdown — use when the user wants the full human audit report; relay its output verbatim instead of parsing JSON.

Example strict CI invocation:

"$FP_PY" "$FP" verify --rpack <path> --strict

Example human audit report:

"$FP_PY" "$FP" verify --rpack <path> --format markdown

Step 3 — Report results

Parse the JSON output (if you ran --format markdown, relay the report verbatim and skip the JSON parsing). Lead the report with two keys, not one:

  • verified — integrity of what is present: nothing that could be checked was tampered with
  • complete — completeness of the evidence set: the chain was found and no artifacts were missing

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.

verify is a skill published in the GitHub repository ryanjmichie-git/forgeproof-plugin (2 stars, last pushed 11d ago), licensed MIT. It adds 66 tokens to every session and 1,189 once invoked, about $0.0003 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 2026-08-31.
