What it does

Dev Verify is an agent skill from hashgraph-online/awesome-codex-plugins. Verify implemented changes before claiming they are complete, fixed, passing, or ready for delivery. Match checks to requested behavior and risk, inspect current evidence, and report limits. Use for completion checks, not general factual answers or a replacement for code review.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `examples.md` and `references/dev-baseline.md`).

It sits in Development. The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is Apache-2.0.

When your agent uses it

  • Completion checks
  • Not general factual answers
  • A replacement for code review

Example prompts

  • “/dev-verify”

What it can do on your machine

Read from SKILL.md and the folder at commit 16b4156. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Dev Verify loads about 1.1k tokens when it runs, and up to ~2k if it reads all its reference files. Until then it costs about 73 tokens; SKILL.md has 538 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~73
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Verify implemented changes before claiming they are complete, fixed, passing, or ready for delivery. Match checks to requested behavior and risk, inspect current evidence, and report limits. Use for completion checks, not general factual answers or a replacement for code review.

Dev Verify

Make completion claims no broader than the evidence. This workflow verifies behavior and artifacts; it does not authorize commits, publishing, merge, or cleanup.

Load baseline

Read references/dev-baseline.md before execution. Resolve paths relative to this skill directory.

Choose evidence

Identify what the user expects to be true and the smallest sufficient proof. Use project commands and conventions; inspect their actual scope before relying on their names.

ClaimRelevant proof
Behavior implementedTests or direct checks of observable acceptance criteria
Bug fixedOriginal reproduction or faithful regression passes
Regression detects the defectObserved failure on original behavior, or isolated mutation proof
Refactor preserves behaviorRelevant characterization tests pass before and after
Build/lint succeedsCorresponding command completes successfully
UI worksRelevant rendered states and interactions, with viewport/device scope stated
Skill/document updatedStructure/link checks plus review of changed instructions/content

Use focused checks for local changes. Broaden for shared contracts, state transitions, persistence, integrations, security, or project-required gates. Do not add tests that merely mirror reversible low-impact edits. A parser or keyword check validates structure, not instruction quality or system behavior.

Run and inspect

  • Use fresh evidence from the final relevant file state. Evidence already produced and inspected during the task remains usable if the tested inputs, dependencies, and environment have not materially changed; do not rerun solely because a new message or handoff occurred.
  • Record exact commands, exit status, and meaningful output. Inspect failures, skipped tests, and warnings that affect the claim. A command being started is not evidence of completion.
  • Keep verification read-only with respect to source and the Git index. Run tools that generate artifacts in an isolated output location where needed. Do not fix code in an independent verification lane unless explicitly reassigned.
  • A worker's summary is not enough: inspect its output and relevant artifacts, or independently reproduce the critical check. Scale repeated verification to remaining uncertainty.
  • When a check fails, distinguish a regression from a pre-existing/environmental failure using evidence. Continue authorized corrective work in the appropriate lane, then rerun affected checks. Do not quietly waive a required failure.

Unavailable hardware, credentials, production access, or test tooling limits the claim. Complete all feasible checks and report missing proof without presenting a local substitute as equivalent.

SDD alignment and completion

Use the current request and relevant existing SDD artifacts as acceptance criteria. If present, .claude/artifacts/{designs,plans,fixes}/ may contain the source contract; select by actual task/file relevance, not the number of artifacts. Later user corrections override stale artifacts.

For substantial work, map requirements to evidence and list missing coverage. Small changes need only a short verification statement. Report what changed, which checks passed or failed, and material residual limits; do not force a fixed checklist into every response.

Verification does not substitute for independent code review. A READY review is not proof that tests ran, and passing tests do not prove every review concern resolved. Use dev-code-review when available and required, or perform the equivalent independent review.

Multi-Agent Profile

Recommended agent_type: worker

When delegation is permitted, give the verifier the current task contract, change scope, and raw artifacts. The verifier evaluates evidence independently and reports claims checked, commands/results, and limitations without changing source or staging files. Follow docs/multi-agent-policy.md if this repository is available; these rules also apply to standalone installations.
