verifying-task-output is a skill for Claude Code from tunahanaliozturk/atelier. It costs 21 tokens per session (218 once invoked), scanned A, original, MIT.

A skill for checking an agent's completed work against the request and then reviewing its code quality. Code-quality review checks how well the result is built after the requested behavior has been checked.

In plain words
What is it for?
Use it after a dispatched task returns to run a specification review, request fixes when needed, and record completed-task metrics.
Why use it?
It catches missing requirements and quality problems before a task is marked complete.

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

verifying-task-output 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 10d 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.

What it actually says

Verifying Task Output

Verify in two stages, in order:

  1. Spec review (spec-reviewer agent): does the output do exactly what the task asked, nothing missing or extra? If not, send the task back to its agent with the gaps.
  2. Code-quality review (code-quality-reviewer agent): only after spec review passes. If it raises issues, send them back.

Mark the task done only when both pass. If an agent cannot resolve a blocker, mark the task blocked and surface it to the user.

When you mark a task done, append a row to the mission's ## Metrics section (creating the section if it is absent) with the task id, the agent that ran it, and your best estimate of the tokens used and the wall-clock duration in minutes. Leave a cell blank if you cannot estimate it. /report reads these rows.

Changes

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.
