grill-with-docs is a cursor rule for Cursor from danielvm-git/bigpowers. It costs 43 tokens per session (589 once invoked), scanned A, original, MIT.

A documentation-based version of an assumption review that checks a plan against official library or API documentation. Each challenge must be supported by a real documentation URL.

In plain words
What is it for?
Use it to inspect a plan, verify its external dependencies, compare the plan with official docs, and update or resolve contradictions.
Why use it?

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

grill-with-docs 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.

Grill With Docs

Use this vs grill-me: grill-with-docs is the doc-grounded variant of grill-me. Use it when the plan relies on external libraries or APIs and every challenge must be grounded in and cite a real documentation URL. Use grill-me for context-only assumption surfacing without fetching docs.

HARD GATE — Every challenge must cite a real documentation URL. No hallucinated APIs.

Process

  1. Read the plan or design under test (specs/release-plan.yaml + epic shards, INTERFACE-OPTIONS.md, etc.).
  2. List assumptions that depend on external libraries or APIs.
  3. For each assumption: fetch or quote official docs; challenge with "docs say X, plan says Y."
  4. Resolve or update the plan inline; unresolved items block plan-work.

Docs mode rules

  • Cite URL + quoted snippet (method name, parameter, version).
  • If docs contradict the plan, plan loses until updated.
  • Prefer official docs over blog posts.

Facts vs. Decisions Boundary

Distinguish between facts and decisions:

  • Facts — things discoverable by reading docs, checking APIs, or exploring the codebase. Do not ask the user to confirm facts; find them yourself.
  • Decisions — choices that require user input (trade-offs, preferences, priorities). Always present options and ask the user to choose.

Never "grill yourself" — if the answer is in the docs, go fetch it. Only ask questions where the user's judgment is needed.

Confirmation Gate

HARD GATE — Do NOT enact the plan or generate specifications until the user explicitly confirms shared understanding. Wait for explicit approval (e.g., "looks good", "confirmed", "proceed") before transitioning to any implementation, spec-writing, or task-slicing step.

Grill With Docs — Question templates

  • "Docs at [URL] show signature foo(bar?: Baz). Your plan calls foo(bar, baz) — which is correct?"
  • "The changelog at [URL] deprecates X in v3. Your plan still uses X — migrate or pin version?"
  • "Error handling in [URL] throws NetworkError. Your plan catches Error only — is that sufficient?"

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.
