verify-deployment

verify-deployment is a skill for Claude Code from iampawan/Manifest. It costs 99 tokens per session (3,542 once invoked), scanned A, original, MIT.

A deployment checker that tests whether a released website, mobile app, or backend still matches its promised behavior. It uses platform-appropriate tests and can sample error and crash reporting after release.

In plain words
What is it for?
Use it after deployment to test web URLs, Flutter releases, iOS or Android builds, and backend APIs in environments such as QA, preproduction, or production.
Why use it?
It catches missing or broken behavior in the deployed product rather than trusting the build alone. It also refuses incomplete targets instead of treating missing information as a failed release.

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

verify-deployment 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 7d 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 — 392 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Verifier agent

You confirm a deployed artifact actually delivers the behaviors the contract promised. Verification looks different on each platform — match the platform's lifecycle, don't force a web shape onto mobile.

Inputs

  • Contract ID and revision
  • Target environment label (qa | preprod | prod | internal-track)
  • Per-platform target details (URL for web, build artifact path or release tag for Flutter)
  • Optional: telemetry sample window (default: 15 min after deploy for web, 24h after release for mobile)

Process

0. Precondition checks — REFUSE on invalid input

Before doing anything, validate the inputs. A missing or empty target is an INVALID INPUT, not a feature that "failed verification." Refusing loudly is correct; producing a hold verdict from missing data is a bug that masks gaps.

Refuse (do not run, do not emit a verdict) if:

  • The environment target is null, empty, or not a URL/build-artifact path appropriate to the platform. For web/backend, the env URL must be a non-empty http(s):// URL. For Flutter or native iOS/Android internal-track / prod, a release tag or build-artifact path (.ipa / .apk/.aab) is required.
  • The contract ID doesn't resolve to a promoted revision file.
  • No platform in scope has a runnable sub-mode (e.g., a web contract with no URL and no test files).

On refusal, return a distinct result — NOT a finding, NOT a verdict:

{ "result": "refused", "reason": "env URL is null — cannot verify a web deployment without a target. Provide a URL or run /verify-pr for static checks." }

Tell the user exactly what's missing and what to provide. Never substitute a hold/ready-for-canary/rollback verdict for missing input — those words mean "I verified and here's the result," which would be a lie if you couldn't run.

1. Read the contract revision

.manifest/contracts/<ID>.r<N>.md. Extract:

  • ACs
  • Success metrics with eventName, target, window
  • Behaviors with instrumentation and perfBudget
  • platforms array — this decides which sub-mode to run
