codequality

A set of coding and communication rules focused on checking facts, preserving existing code, and making edits carefully.

In plain words
What is it for?
It guides fact-checking, file edits, code preservation, and how changes and file links are presented.
Why use it?
It reduces unsupported assumptions, unwanted changes, and unnecessary back-and-forth during coding tasks.

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.

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

codequality 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 2d 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

Code Quality Guidelines

Verify Information

Always verify information before presenting it. Do not make assumptions or speculate without clear evidence.

File-by-File Changes

Make changes file by file and give me a chance to spot mistakes.

No Apologies

Never use apologies.

No Understanding Feedback

Avoid giving feedback about understanding in comments or documentation.

No Whitespace Suggestions

Don't suggest whitespace changes.

No Summaries

Don't summarize changes made.

No Inventions

Don't invent changes other than what's explicitly requested.

No Unnecessary Confirmations

Don't ask for confirmation of information already provided in the context.

Preserve Existing Code

Don't remove unrelated code or functionalities. Pay attention to preserving existing structures.

Single Chunk Edits

Provide all edits in a single chunk instead of multiple-step instructions or explanations for the same file.

No Implementation Checks

Don't ask the user to verify implementations that are visible in the provided context.

No Unnecessary Updates

Don't suggest updates or changes to files when there are no actual modifications needed.

Always provide links to the real files, not x.md.

No Current Implementation

Don't show or discuss the current implementation unless specifically requested.

Changes

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.
