sdd-validate

sdd-validate is a skill for Claude Code from 3062-in-zamud/knowledgine. It costs 42 tokens per session (492 once invoked), scanned A, original, MIT.

A validation workflow that checks whether an implementation meets the acceptance criteria in its specification. Acceptance criteria are the conditions a feature must satisfy; the workflow links them to tests and reports pass or fail.

In plain words
What is it for?
Use it after implementation or during partial work to inspect the requirements and design, map criteria to tests, run the test suite, and produce a validation report.
Why use it?
It exposes missing tests and gaps between the written design and the code before a pull request is created.

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

sdd-validate 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 11d 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

sdd-validate

Purpose

Verify that the implementation actually satisfies what was specified. Catches gaps between requirements and implementation before the review phase.

When to Use

  • After completing all tasks in tasks.md
  • Before creating a PR
  • During implementation to check partial progress

Arguments

  • $ARGUMENTS: Spec ID (e.g., KNOW-001) or path to spec directory

Step-by-Step Instructions

1. Load Acceptance Criteria

Read specs/KNOW-{NNN}-*/requirements.md and extract all acceptance criteria (AC-1, AC-2, ...).

2. Map Criteria to Tests

For each acceptance criterion:

  1. Search the test files for tests that exercise this criterion
  2. Look for test descriptions that mention the criterion or its key behavior
  3. If no test found, flag as UNCOVERED

3. Run Tests

pnpm test:run

4. Check Design Compliance

Compare implementation against design.md:

  • Do exported interfaces match what was designed?
  • Does the data flow match the described steps?
  • Were key design decisions followed?

5. Generate Report

## Validation Report: KNOW-{NNN}

### Acceptance Criteria Coverage

| Criterion | Test File | Status                  |
| --------- | --------- | ----------------------- |
| AC-1: ... | tests/... | PASS / FAIL / UNCOVERED |
| AC-2: ... | tests/... | PASS / FAIL / UNCOVERED |

### Design Compliance

- [ ] Interfaces match design.md
- [ ] Data flow matches design.md
- [ ] Design decisions followed

### Build Status

pnpm verify: PASS / FAIL

### Coverage

pnpm test:coverage: XX% (target: 80%)

### Summary

X/Y acceptance criteria covered and passing.
Z criteria need attention.

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.
