don-cheli-sdd: Skill for Claude Code

.agent/skills/doncheli-spec-score/SKILL.md

doncheli-spec-score is a skill for Claude Code from doncheli/don-cheli-sdd. It costs 49 tokens per session (560 once invoked), scanned A, original, Apache-2.0.

A specification-quality checker for written software requirements. It scores completeness, clarity, testability, consistency, and scope, then assigns a grade.

In plain words
What is it for?
It reviews a specification file or the current specification, gives line-specific improvement suggestions, and can save a score card.
Why use it?
It helps reveal missing cases, vague wording, contradictions, and requirements that cannot be checked clearly before implementation begins.

Skill for Claude Code

Written for Claude Code: shipped in a Claude Code plugin.

This is doncheli/don-cheli-sdd's own configuration. It tells Claude Code how to work on don-cheli-sdd itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything don-cheli-sdd configures →

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

doncheli-spec-score 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 13d 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

Don Cheli: Spec Score

Instructions

  1. Accept a spec file path or read the current spec from .dc/specs/
  2. Evaluate the spec across 5 dimensions (0–10 each):
    • Completeness: all scenarios covered, no missing edge cases
    • Clarity: unambiguous language, no "should", "may", "probably"
    • Testability: each scenario has a verifiable, binary outcome
    • Consistency: no contradictions between scenarios or with existing specs
    • Scope control: no out-of-scope behavior mixed in, single responsibility
  3. For each dimension below 7, provide 2–3 specific improvement suggestions with line references
  4. Compute a weighted total score (Completeness 30%, Clarity 25%, Testability 25%, Consistency 10%, Scope 10%)
  5. Assign a grade: A (90-100), B (75-89), C (60-74), D (below 60)
  6. Grade D specs must be improved before implementation — flag as a hard blocker
  7. Optionally save the score card to .dc/spec-scores/<spec-name>-<date>.md

### Scores
| Dimension     | Score | Weight | Weighted |
|--------------|-------|--------|---------|
| Completeness  |   8   |  30%   |   2.4   |
| Clarity       |   6   |  25%   |   1.5   |
| Testability   |   9   |  25%   |   2.25  |

| Scope Control |   8   |  10%   |   0.8   |
| **Total**     |       |        | **7.65**|

### Grade: B

### Improvement Suggestions

**Clarity (score: 6)**
- Line 14: "the system should respond quickly" — define SLA (e.g., "within 200ms")
- Line 28: "valid payment method" — list accepted types explicitly

### Verdict
Spec is implementation-ready with minor clarity fixes recommended.
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.
