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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00049 | $0.00560 |
| Opus 5 | $0.00024 | $0.00280 |
| Sonnet 5 | $0.00010 | $0.00112 |
| Haiku 4.5 | $0.00005 | $0.00056 |
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
- Accept a spec file path or read the current spec from
.dc/specs/ - 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
- For each dimension below 7, provide 2–3 specific improvement suggestions with line references
- Compute a weighted total score (Completeness 30%, Clarity 25%, Testability 25%, Consistency 10%, Scope 10%)
- Assign a grade: A (90-100), B (75-89), C (60-74), D (below 60)
- Grade D specs must be improved before implementation — flag as a hard blocker
- Optionally save the score card to
.dc/spec-scores/<spec-name>-<date>.md
Output Format
## Spec Score — checkout.feature — 2026-03-28
### Scores
| Dimension | Score | Weight | Weighted |
|--------------|-------|--------|---------|
| Completeness | 8 | 30% | 2.4 |
| Clarity | 6 | 25% | 1.5 |
| Testability | 9 | 25% | 2.25 |
| Consistency | 7 | 10% | 0.7 |
| 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.
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.

doncheli-spec-score is a skill published in the GitHub repository doncheli/don-cheli-sdd (57 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 49 tokens to every session and 560 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
