quick-fix

quick-fix is a cursor rule for Cursor from danielvm-git/bigpowers. It costs 50 tokens per session (1,163 once invoked), scanned A, original, MIT.

A fast path for very small fixes that change only data, such as a missing key, typo, or configuration value, without changing program logic.

In plain words
What is it for?
Use it for a one-file change of no more than five lines, then pass the result to the release procedure after its guard checks succeed.
Why use it?
It avoids unnecessary process for low-risk changes while stopping and switching to a fuller bug-fixing process if the change becomes more complex.

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

quick-fix scanned grade A with 1 finding 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.

Quick Fix

HARD GATE — ALL entry criteria must pass before invoking quick-fix. If any guardrail triggers during execution, abort immediately and fall back to investigate-bug. Do NOT use quick-fix for logic changes, multi-file edits, or diffs > 5 lines.

Fast-track for trivial data-only fixes that do not require the full bug-fix chain.

When a bug fix is purely data — an add-missing-key, a typo correction, a config value update — the standard 6-skill chain (investigate-bug → diagnose-root → develop-tdd → kickoff-branch → verify-work → release-branch) is wasteful overhead. Quick-fix collapses it to 2 skills: quick-fix then release-branch.

Discovered gate failures (e51s04)

A Preflight, golden suite, or baseline red failure discovered during unrelated work is valid quick-fix entry when the root cause is a data-only gap (missing key, typo, stale config) — no user-reported bug required. If guardrails abort (logic change, >1 file, >5 lines), fall back to fix-bug instead of narrating and continuing.

Entry Criteria (ALL must be true)

Before invoking quick-fix, evaluate every item in this checklist:

  1. Purely data change — adding a missing key, fixing a typo, updating a config value, correcting a constant
  2. No logic change — no function signature, condition, loop, or control flow is modified
  3. No refactor risk — the change does not reorganize or rename existing structures
  4. No API surface change — no exported symbol, interface, or contract changes
  5. Verifiable with a single assertion — one test, one curl, one grep can prove it works
  6. Affects ≤ 1 file
  7. Affects ≤ 5 lines changed

Guardrails (HARD ABORT — all must pass)

If ANY guardrail triggers, abort immediately and suggest investigate-bug instead:

Guardrail Check
>1 file The fix touches more than one file
>5 lines The diff exceeds 5 lines
Logic change Any function signature, condition, or loop is modified
Complex verify The verify command is more than one pipeline
Test breakage Running npm test or equivalent breaks any existing test

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.

quick-fix is a cursor rule published in the GitHub repository danielvm-git/bigpowers (267 stars, last pushed 27d ago), licensed MIT. It adds 50 tokens to every session and 1,163 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
