~aod-spec

~aod-spec is a skill for Claude Code from davidmatousek/agentic-oriented-development-kit. It costs 71 tokens per session (1,617 once invoked), scanned A, a copy of ~aod-spec, MIT.

A checker for feature specification files named spec.md. It looks for required sections, unresolved questions, testable acceptance criteria, and clear boundaries.

In plain words
What is it for?
Use it to review whether a specification is complete enough to build and test, including its user scenarios, requirements, success measures, and scope.
Why use it?
It catches missing or unclear requirements before architecture and implementation begin.

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

~aod-spec 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 1mo 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.

Spec Validator Skill

Purpose

Automatically validates specification files (spec.md) for completeness, quality, and readiness for architecture and implementation phases. Implements FR-004 from the feature specification.

How It Works

Step 1: Locate Specification

  • Search for specs/*/spec.md files in the repository
  • If specific feature directory provided, validate that spec.md
  • Report if spec.md not found

Step 2: Validate Mandatory Sections

Check for required sections per specification template:

  • User Scenarios & Testing (mandatory)

    • User stories with acceptance scenarios
    • Independent test criteria
    • Edge cases identified
  • Requirements (mandatory)

    • Functional requirements
    • Key entities
  • Success Criteria (mandatory)

    • Measurable outcomes
  • Scope (mandatory)

    • In scope
    • Out of scope
  • Assumptions (optional but recommended)

  • Dependencies (optional but recommended)

  • References (optional)

Step 3: Check for Clarification Markers

  • Grep for [NEEDS CLARIFICATION] markers
  • Report all instances with line numbers
  • Specification not ready if any markers remain

Step 4: Validate Testable Criteria

  • Check that each user story has clear acceptance scenarios
  • Verify success criteria are measurable (contain numbers/percentages)
  • Ensure requirements have validation criteria

Step 5: Check Scope Boundaries

  • Verify "In Scope" section exists and is populated
  • Verify "Out of Scope" section exists (clear boundaries)
  • Check that scope is clearly bounded (not open-ended)

Step 6: Generate Validation Report

Report format:

Specification Validation Report

File: specs/{feature-id}/spec.md

Mandatory Sections:
- [✓/✗] User Scenarios & Testing
- [✓/✗] Requirements (Functional Requirements)
- [✓/✗] Success Criteria
- [✓/✗] Scope (In/Out)

Quality Checks:
- [✓/✗] No [NEEDS CLARIFICATION] markers
- [✓/✗] All requirements testable
- [✓/✗] Scope clearly bounded
- [✓/✗] Success criteria measurable

Status: READY / NOT READY

Issues Found:
1. [Issue description with line number]
2. [Issue description with line number]

Recommendations:
- [Specific action to resolve each issue]

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.
