dhpk-feature-verify

dhpk-feature-verify is a skill for Claude Code from hmj1026/dhpk. It costs 100 tokens per session (1,509 once invoked), scanned A, original, MIT.

A read-only procedure for checking whether a deployed feature behaves as expected through its API or other observable runtime evidence. A post-deploy smoke test is a quick check after release that the main behavior still works.

In plain words
What is it for?
Use it for deployed feature verification, API response checks, smoke tests, and production diagnosis when an approved observation path exists.
Why use it?
It helps confirm production behavior and diagnose issues without changing application data, configuration, or deployment state.

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

dhpk-feature-verify scanned grade A with 1 finding 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Feature Verify — Runtime-First API Verification

Verify deployed behavior with read-only runtime evidence:

Primary-model analysis → optional independent reviewer → integrated verdict

Use this for post-deploy checks, smoke tests, and production diagnosis. For local tests use the repository verification route; for changes use flow-guide in feature mode; for code review use change-verdict.

When NOT to Use

  • The requested action changes application data, configuration, or deployment state.
  • The task is to implement or modify a feature; use flow-guide in feature mode.
  • The task is a code, security, or test review rather than runtime behavior verification.
  • There is no read-only endpoint, observation path, or approved test environment that can produce evidence for the requested claim.

Required References

Read these at the indicated phase:

Bash is permitted only for read-only curl and observation queries reviewed against the safety rules. Missing endpoint allowlist means P3 is skipped.

P0 — Scope and Safety

  1. Select --env, defaulting to test, and load its configuration.
  2. Run scripts/health-probe.sh <health-url> (3 attempts, 2-second timeout).
  3. Compare local HEAD with the deployed version and warn on mismatch.
  4. Confirm every planned operation is read-only.
  5. Determine L4/L3/L2-API/L2-OBS/L1 using the playbook matrix.

API unreachable with logs gives L2-OBS; without logs gives L1. At L1 skip P3/P4. --level L2 remains an alias for L2-API.

P1 — Diff-Lite Scope

Follow blackbox-testing.md § P1. Map git diff main...HEAD --name-only to affected endpoints, dependency chains, active triggers, and passive targets. This phase scopes behavior; it does not judge code quality. If no diff exists, build scope from the user's feature description.

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.

dhpk-feature-verify is a skill published in the GitHub repository hmj1026/dhpk (2 stars, last pushed today), licensed MIT. It adds 100 tokens to every session and 1,509 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
