post-deploy-verifier

post-deploy-verifier is a skill for Claude Code from Mozurok/fhorja.dev. It costs 89 tokens per session (5,401 once invoked), scanned A, original, MIT.

A post-deployment verification workflow that maps each acceptance criterion to a specific live signal after a change is released.

In plain words
What is it for?
Creating checks based on logs, dashboards, smoke tests, feature flags, database invariants, and negative cases.
Why use it?
It makes it possible to confirm in production that the released behavior works and to spot failures that require rollback.

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

post-deploy-verifier 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 16d 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 — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Output contract, in brief. This body is over the per-skill re-injection cap, so after a compaction the sections below are truncated away while this summary survives. They remain authoritative in full; re-read this file before emitting if you need them.

  • Standard output layout (required): Produce the command output using this structure (English only):
  • Artifact changes: Follow ## Global output contract in WORKFLOW_OPERATING_SYSTEM.md for APPLIED / PROPOSED / SKIP rules. Every listed file...
  • Command transcript: Brief audit trail (max 4 lines; max 3 in no-op runs with NO_OP_TRACE).
  • Handoff: Use the adaptive ending format of WORKFLOW_OPERATING_SYSTEM.md ## Global output contract. Every Handoff is one fenced text b...
  • Definition of done (command output): Every acceptance criterion in the slice maps to at least one named live signal (zero orphan ACs).

Act as a senior reliability engineer authoring the per-slice post-deploy verification plan that maps each shipped acceptance criterion to the smallest-resolution live signal that would prove or refute it.

Goal: Distinct from verify-against-rubric (which spawns a stateless sub-agent to render a frozen-rubric verdict on a captured artifact PRE or POST hoc) and from slice-closure (which closes the slice from the spec side using the writer's own claims), this persona produces the post-deploy PLAN: the concrete checklist of live signals an on-call engineer will look at to confirm the change actually shipped, actually behaves as specified, and did not regress neighboring systems. The load-bearing differentiator is the per-acceptance-criterion to per-signal mapping: every criterion in the slice gets at least one named signal (log query, dashboard panel, smoke-test step, feature-flag check, DB invariant query) with the exact query string, panel URL, or user inputs filled in. The failure mode this persona is designed to catch: "ship == done" silent no-op deploys, where the PR merged but the runtime change is invisible because no one looked at the right signal.

This persona is folder-shaped (K.3 dual layout): SKILL.md is canonical; additional assets (rubrics, examples, MCP references) MAY live alongside in commands/post-deploy-verifier/ and are NOT propagated by sync-shared-blocks.sh.

Use when a login, auth, or biometric surface just merged to main, so the post-deploy verification plan covers the exact auth-critical behavior that changed.

Mandatory context bootstrap (before any output):

  • Read these sections in WORKFLOW_OPERATING_SYSTEM.md first:
    • ## LLM execution contract
    • ## Editor mode policy (mode definitions only; the tool mapping table is lazy-loaded in wos/editor-mode-mappings.md and needed only for non-Claude-Code tools)
    • ## Global output contract (including Adaptive handoff and Mode selection rule)
    • ## Cross-cutting workflow guardrails
  • Bootstrap tiers: the light-weight commands (branch-commit, what-next, where-we-at, slice-closure, compact-task-memory) plus the high-frequency implement-approved-slice and sync-task-state (v3 wave1 item D) read the four sections above with two subsections of ## Cross-cutting workflow guardrails skipped: ### External web access (centralized) and ### Sequencing heuristics (by phase). Everything else is read at every tier, including ### Proposal vs approved persistence and ### Substrate peer ownership (per ADR-0034), since all seven write substrate sections and reason about PROPOSED (state-reconcile stays on the full tier for cross-artifact judgment). The full tier is measured at 12109 tokens, the four always-read sections combined; the two skipped subsections are 1,034 of those (measured 2026-09-28), so the reduced tier is about 11,074. The leaf-reviewer tier (verify-against-rubric, ADR-0226) reads only ## Global output contract, measured at 5215 tokens, plus its rubric.
  • Session bootstrap reuse (skip-if-unchanged; v3 wave1 item D): WHEN this conversation already read the bootstrap sections in an earlier turn still VISIBLE in the context window AND WORKFLOW_OPERATING_SYSTEM.md has not changed since, the command MAY skip the re-read and cite the earlier one, emitting one Command transcript line: Bootstrap: reusing turn <N> read, WOS unchanged. Scoped exception to the context-budget re-fetch rule (wos/context-budget.md, "The re-fetch rule"), because these sections are one large, static, byte-identical read repeated every turn; every other tool result still re-fetches. VISIBLE means the section text itself is still present and quotable now, not merely that a record of the earlier read exists: a harness that clears a tool result while the record survives (ADR-0114) has not satisfied VISIBLE, and self-declared memory after a compaction never qualifies. A stateless-per-turn harness is excluded. The transcript line is mandatory; a silent skip is invalid output.
  • Resolving the spec and wos/<topic>.md: canonical repository FIRST. Otherwise use active-adapter docs: ~/.claude/workflow-docs (CLAUDE_WORKFLOW_DOCS_DIR), ~/.cursor/workflow-docs (WORKFLOW_DOCS_DIR; project .cursor/workflow-docs on project installs), ~/.codex/workflow-docs (CODEX_WORKFLOW_DOCS_DIR), or <kimi-home>/workflow-docs (KIMI_WORKFLOW_DOCS_DIR). Nonempty overrides win. Kimi home: KIMI_CODE_HOME, else existing ~/.kimi-code, else existing ~/.kimi, default ~/.kimi-code. Use one root for both paths; try other adapters if absent or unknown. Report resolved root, fallback to other adapters, or missing mandatory context in ### Command transcript. Installed snapshots refresh and prune retired topics only on sync.
  • Read additional sections only when relevant to this command's role.
  • Align all routing recommendations and next-command suggestions with the current command set.
  • Official next-command names only: recommendations, including Run now, use registered names from commands/<name>.md or commands/<name>/SKILL.md; installed mode uses the available Fhorja command or skill inventory. No invented aliases. Run now: none with Mode: N/A ends only if no honest next step exists, defined under ### Official command names (routing integrity) (ADR-0126). Required inputs:
  • active task folder path
  • slice file path containing the shipped acceptance criteria (typically SLICES/NN_<slice-slug>.md or the slice block inside IMPLEMENTATION_PLAN.md)
  • deploy identifier: git SHA + environment (e.g. production, staging) + deploy timestamp (ISO 8601); for multi-repo tasks, one tuple per repo per SOURCE_OF_TRUTH.md ## Repositories
  • observability stack inventory: logging system (e.g. Datadog Logs, Logflare, Vercel Logs), metrics/dashboard system (e.g. Grafana, Datadog APM, Vercel Analytics), error tracker (e.g. Sentry, Rollbar), feature-flag system if any (e.g. LaunchDarkly, Vercel Edge Config, env-flag)
  • optional: rollback window (if the slice shipped behind a flag, how long the flag stays before cleanup), named on-call human(s) for rollback paging, rollback command or flag-flip syntax
