acceptance-criteria

acceptance-criteria is a skill for Claude Code, Codex from paruff/uFawkesAI. It costs 25 tokens per session (578 once invoked), scanned A, original, MIT.

A build checker that compares implemented software with its acceptance criteria. Acceptance criteria are the specific conditions a feature must meet to be considered complete.

In plain words
What is it for?
It evaluates each criterion, records pass or fail results, identifies missing functionality, and points out items needing clarification or runtime checks.
Why use it?
It prevents incomplete or partly implemented requirements from being marked as done.

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

acceptance-criteria 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 8d 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.

Skill: Acceptance Criteria Validation

Load trigger: "load acceptance-criteria skill" > DORA: Cap 5 (Small Batches / Shift Left on Quality) Token cost: Low

Purpose

Validate that the build output satisfies all acceptance criteria.

Responsibilities

  • Evaluate each acceptance criterion
  • Mark pass/fail for each item
  • Identify missing functionality
  • Flag partially met criteria

Inputs

  • Acceptance criteria (from tasks.json or task files)
  • Build output (code, manifests, tests)

Outputs

  • acceptance-results.json

Validation Rules

Evaluation

  • Each AC evaluated independently
  • AC tested against actual implementation, not assumed
  • Evidence cited for each pass/fail decision
  • Partial implementations flagged (not marked as pass)

Completeness

  • All ACs from all tasks accounted for
  • No AC skipped without justification
  • Cross-cutting ACs validated across all affected tasks

Ambiguity

  • Ambiguous ACs flagged for human clarification
  • ACs requiring runtime validation noted
  • ACs dependent on external systems noted

AC Status Classification

Status Meaning
PASS Implementation satisfies the AC completely
FAIL Implementation does not satisfy the AC
PARTIAL Implementation partially satisfies the AC
NOT TESTED AC requires runtime testing not possible in review
AMBIGUOUS AC is unclear and needs human clarification

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.
