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 | $0.00052 | $0.00718 |
| Opus 5 | $0.00026 | $0.00359 |
| Sonnet 5 | $0.00010 | $0.00144 |
| Haiku 4.5 | $0.00005 | $0.00072 |
Grade A, and why
plan-refactor 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 today.
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.
How it starts
The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Plan Refactor
HARD GATE — HARD GATE — Before refactoring, document the current behavior and why it is wrong. Extract one invariant that must be preserved. If you skip this, you will break things you don't expect.
Create a detailed refactor plan through a user interview. Save output to specs/REFACTOR_LATEST.md.
Steps
-
Ask the user for a long, detailed description of the problem they want to solve and any potential ideas for solutions.
-
Explore the repo to verify their assertions and understand the current state of the codebase.
-
Ask whether they have considered other options, and present other options to them.
-
Interview the user about the implementation. Be extremely detailed and thorough.
-
Hammer out the exact scope of the implementation. Work out what you plan to change and what you plan not to change.
-
Look in the codebase to check for test coverage of this area. If there is insufficient test coverage, ask the user what their plans for testing are.
-
Break the implementation into a plan of tiny commits. Remember Martin Fowler's advice: "make each refactoring step as small as possible, so that you can always see the program working."
-
Save the refactor plan to
specs/REFACTOR_LATEST.md. Create thespecs/directory if it doesn't exist.
Problem Statement
The problem that the developer is facing, from the developer's perspective.
Solution
The solution to the problem, from the developer's perspective.
Commits
A LONG, detailed implementation plan. Write the plan in plain English, breaking down the implementation into the tiniest commits possible. Each commit should leave the codebase in a working state.
Each commit entry follows this format:
N. <commit description> → verify: <runnable command>
Decision Document
A list of implementation decisions that were made:
- The modules that will be built/modified
- The interfaces of those modules that will be modified
- Technical clarifications from the developer
- Architectural decisions
- Schema changes, API contracts, specific interactions
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.

plan-refactor is a cursor rule published in the GitHub repository danielvm-git/bigpowers (163 stars, last pushed 2d ago), licensed MIT. It adds 52 tokens to every session and 718 once invoked, about $0.0003 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 2026-09-03.
