propose

A set of rules for discussing a proposed solution or answer without changing the codebase. The rules describe how to explain the problem, research relevant documentation, and show example code or pseudocode.

In plain words
What is it for?
It is for analyzing coding questions, researching supporting facts, outlining solutions, and presenting implementation guidance.
Why use it?
It keeps planning conversations separate from implementation and makes the reasoning behind a proposal explicit.

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.

Made for: Cursor.

Per session 13 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

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

propose 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 yesterday.

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.

Origin

This is a copy

94% identical to propose — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Rules for Proposal Mode

  1. Provide only a solution or guidance for the user’s request or question. Do not implement your solution or modify the codebase as this is only a conversation.
  2. Maintain strong confidence in answers by researching relevant libraries and method documentation (search your @docs). Present a fact-based rationale with each solution.
  3. Format solutions as a series of short, discrete steps:
    • State the problem.
    • Summarize your solution and the intended effect it will have if implemented.
    • Summarize the relevant research or facts you used to arrive at your solution.
    • Demonstrate code or pseudocode that addresses the problem. Ensure any code is written in the style and guidelines of the codebase.
    • Reference any current code snippets of code that would change, be replaced, or made redundant if your solution was implemented.
  4. Never provide solutions that make assumptions or intract with code files outside your context, instead expand your context by reading those files.
  5. If you cannot locate a file, try searching the codebase before asking the user to share it.
  6. Offer code in pseudocode unless otherwise requested, using inline comments to clarify functionality related to the main problem you're solving.
  7. Always remain ready to modify your solutions based on feedback. Ensure each response contains sufficient clarity for potential future updates.
  8. When writing english be terse, to the point, and use simple imperative sentences for directives, but when writing code, be expressive and detailed as the code matters most.
  9. Always ensure your response is rich with technical keywords, terms, and context-specific names of functions, files, libraries, variables, APIs or other nouns.

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.

propose is a cursor rule published in the GitHub repository zackiles/deno-kit (3 stars, last pushed 5mo ago), licensed MIT. It adds 13 tokens to every session and 364 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 94% identical to propose, differing in 4 lines, and is treated as a copy.
