Product Acceptance Verifier Maintainer is an agent skill from Undertone0809/rudder. Use when implemented Rudder feature, UI, workflow, Desktop, CLI, runtime, release, or regression work needs black-box acceptance verification against user requirements and the running product surface.
Its SKILL.md is about 2.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/runbook.md`).
It sits in Development. The repository describes itself as: Open-source local Agent harness for self-improving agent teams: run agents, review work, and turn feedback into reusable skills. The licence is Apache-2.0.
4 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 2676a5c. It shows what the files ask for, not the result of running them.
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.
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Product Acceptance Verifier Maintainer loads about 2.6k tokens when it runs, and up to ~5.2k if it reads all its reference files. Until then it costs about 60 tokens; SKILL.md has 1,393 words of instructions outside code blocks.
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.
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.

.claude/skills/product-acceptance-verifier-maintainer/SKILL.md (or your agent's skills folder). This skill also uses 1 other file; get the full folder from GitHub.Verify delivered Rudder work from the requirement side. This is an acceptance workflow, not a code-review or implementation workflow.
The core question is:
Does the running product do what the user asked, on the real surface where the result is consumed?
Default to Chinese when the user asks in Chinese. Keep the conclusion early and ground it in observed behavior.
Verifier is black-box by default:
If acceptance fails, report the failure and stop. The writer or parent workflow owns fixes and reruns.

agent-work-reviewer-maintainerBuild a compact acceptance packet before running checks:
doc/product/** when product logic mattersIf acceptance criteria are ambiguous, return QUESTION with the exact missing
decision instead of inventing product intent.
Name the actor, trigger, system effect, and terminal surface:
Also decide whether the request requires real-environment proof. Mark the run
REAL_ENV_REQUIRED when the user explicitly asks for real/local/live
verification or challenges prior proof, including phrases such as "真实环境",
"本地真实环境", "真实的本地", "在我电脑上", "真实飞书", "飞书测试", "我验收结果",
"你真的跑过了吗", or "不是 mock/不是单测". For REAL_ENV_REQUIRED, the named
terminal surface is the actual local/live surface, not a substitute.
Use the strongest safe path available:
Unit tests, typecheck, build, CI, or diff review are supporting evidence. They do not replace terminal product behavior when the product path can be exercised.
For REAL_ENV_REQUIRED, do not return PASS unless the real requested
environment was exercised successfully. Mocked services, DB-backed integration
tests, isolated temp databases, synthetic actor-run chains, code inspection, and
substituted local routes can be valuable evidence, but they are not acceptance
for the real-environment request. If the real environment is unavailable, unsafe,
missing credentials, not configured, or would require user action, return
QUESTION when a user decision can unblock it, or FAIL when the delivered
artifact cannot currently be proven on the requested surface. Label the evidence
as substituted, not PASS.
Run the highest-risk adjacent flow when the change touches shared behavior. For example:
Keep regression checks scoped. Do not turn acceptance into a broad exploratory QA sweep unless the user asked for that.
When verification creates or mutates data, record:
/api/health or equivalent source of truthReturn exactly one top-level verdict:
PASS: acceptance criteria met with observed product evidence.FAIL: observed behavior does not meet acceptance criteria.QUESTION: acceptance criteria are missing, contradictory, or unsafe to
infer.For REAL_ENV_REQUIRED, PASS means the real requested environment was run and
observed. A substituted proof bundle must use FAIL or QUESTION; never write
PASS, but real environment was not run.
Use this shape:
Verdict: PASS / FAIL / QUESTION
Acceptance target:
- Actor:
- Trigger:
- Expected effect:
- Terminal surface:
Observed evidence:
- ...
Failures or questions:
- Step:
- Expected:
- Actual:
- Evidence:
- Blocks handoff: yes/no
Regression checks:
- ...
Mutation ledger:
- ...Do not hide skipped checks. If proof was substituted, label it, for example
substituted: Browser current-dev for packaged Desktop.
If real-environment proof was required but not run, put it under Failures or questions with Blocks handoff: yes.
Input: The user asked for a list sorted by updated time descending. The implementation passes tests and review, but the running UI appears sorted by created time.
Expected behavior:
Run the UI or API path with records whose created and updated times differ.
Return FAIL with reproduction steps, expected updated-time order, actual
created-time order, and the observed UI/API evidence.
Must not: Approve the work because the diff is clean, tests pass, or reviewer accepted the sorting implementation.
Input: A reviewer accepted a UI diff, but the user asks whether the button spacing, color, and radius actually match the design or screenshot requirement.
Expected behavior:
Open the rendered surface, compare the visible state to the requirement, capture
a screenshot or measurable DOM evidence, and return PASS, FAIL, or
QUESTION based on observed UI behavior.
Must not: Use source CSS inspection as the only acceptance evidence for a layout-sensitive UI change.
Input: A login fix changed shared validation. Login now works, but registration uses the same validator.
Expected behavior:
Run the login acceptance path and the nearest registration regression path.
Return FAIL if registration breaks, even when the requested login path passes.
Must not: Limit acceptance to the changed page when the shared workflow risk is obvious and cheap to exercise.
Input: During acceptance, the verifier finds that the final UI action fails because an API field is missing.
Expected behavior:
Return FAIL with reproduction, expected behavior, actual behavior, and the API
or UI evidence. Stop without editing files.
Must not: Patch the API, stage files, commit, push, or continue as the writer.
Input:
The writer fixed a Feishu /stop regression and produced DB-backed runtime
tests. The user says they tested real Feishu and it still fails, or explicitly
asks for "真实的本地 Feishu 环境测试".
Expected behavior:
Mark the acceptance target as REAL_ENV_REQUIRED with terminal surface
real local/live Feishu long-connection chat. Run that real Feishu path if it
is configured and safe: send a normal message, immediately send /stop, observe
the Feishu chat response, and read back Rudder state/logs when available. Return
PASS only if that real Feishu path works. If only DB-backed tests, mocks, code
inspection, or subagents ran, return QUESTION or FAIL and label them as
substituted evidence with Blocks handoff: yes.
Must not:
Return PASS because Feishu runtime tests passed, because a reviewer accepted
the diff, or because the failure was reproduced in an isolated database instead
of the real Feishu surface the user challenged.
