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 | $0.00149 | $0.00657 |
| Opus 5 | $0.00075 | $0.00329 |
| Sonnet 5 | $0.00030 | $0.00131 |
| Haiku 4.5 | $0.00015 | $0.00066 |
Grade A, and why
ask-questions-if-underspecified 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 12d 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
Ask Questions If Underspecified
The "stop and clarify" gate. Many AI Coding failures trace back to "Agent assumed X, X was wrong, 4 hours wasted." This skill catches that early.
Core principle
Only ask decision-shaping questions. If the answer changes nothing about what gets built, don't ask.
Question taxonomy
For each candidate question, classify:
| Type | Ask? | Example |
|---|---|---|
| Decision-shaping | YES | "Should L4 PHI be stored encrypted at rest or only redacted?" |
| Preference | Only if 2 acceptable paths | "Frontend React or Vue?" |
| Trivia | NO | "What color is the button?" (decide and move on) |
| Compliance-touching | ALWAYS | Anything touching tier / model / audit |
Workflow
- List unknowns surfaced from the upstream artifact (PRD / TDD / design).
- Classify each per the taxonomy.
- Keep at most 5 of type decision-shaping or compliance-touching.
- Phrase each question so the answer is bounded (multiple-choice or numeric).
- Format with AskUserQuestion tool when available; otherwise inline.
- Never ask "is this OK" / "should I proceed" — those are not clarifications.
Output
A list of ≤ 5 questions, each with:
- Header (≤ 12 chars chip label)
- Why it matters (one line)
- 2-4 mutually exclusive options (or "numeric input")
- Recommended default
Common failure modes
- Question dump — asking 15 questions exhausts the user. Cap at 5; everything else is your call.
- Open-ended phrasing — "What do you think about X?" produces non-actionable answers. Always bound.
- Asking after committing — questions came too late, work already started. Run this skill earlier in the SOP.
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.

ask-questions-if-underspecified is a skill published in the GitHub repository charliehzm/medharness (86 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 149 tokens to every session and 657 once invoked, about $0.0007 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.
