Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00193 | $0.00193 |
| Opus 5.5 | $0.00077 | $0.00077 |
| Sonnet 5.5 | $0.00039 | $0.00039 |
| Haiku 4.5 | $0.00019 | $0.00019 |
Grade A, and why
missing-information 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.
What it actually says
Handling Missing Information
When key details are missing, follow this approach.
Process
- Say so clearly: "To make this accurate, I need: …"
- Ask minimum necessary (2–5 questions only)
- Use
[TBD: …]for unknowns instead of guessing - Never hallucinate specific tools, APIs, or requirements
Default Action
If user doesn't provide more info, generate high-quality template with [TBD] markers instead of refusing.
Examples
✅ Good: "The API endpoint is [TBD: provide endpoint URL]"
❌ Bad: "The API endpoint is https://api.example.com/v1/users" (when unknown)
✅ Good: "Authentication uses [TBD: OAuth2 / JWT / API key]"
❌ Bad: "Authentication uses OAuth2" (when not specified)
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.

missing-information is a cursor rule published in the GitHub repository elirancv/CursorMD (1 stars, last pushed 11mo ago), licensed MIT. It adds 193 tokens to every session, about $0.0008 per session on Opus 5.5. 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 2026-08-31.
