morgankreyandfactory-droid[bot] 63ea24259a docs: Add rules hygiene guidance for AI agents (#49143)
## Summary
- Adds a "Rules Hygiene" section to `.rules` after the existing Build
Guidelines section
- Establishes clear guidelines for when/how AI agents should propose
`.rules` changes
- Adds a "Crash Investigation" section with reference to
`script/crash-to-prompt` and other crash tooling

## What's in the Rules Hygiene section

**After any agentic session:** Agents should include a "Suggested .rules
additions" heading in their PR description if they discover non-obvious
patterns. Reviewers decide what gets merged.

**High bar for new rules:** Editing existing rules is always welcome.
New rules must be (1) non-obvious, (2) repeatedly encountered, and (3)
specific enough to act on. Single-crate rules go in that crate's
`.rules`.

**No drive-by additions:** Rules emerge from validated patterns through
a 3-step workflow: agent notes pattern → team validates → dedicated
commit.

## Context
Part of the Background Agent Pipeline initiative (BIZOPS-801). As we
scale automated crash investigation, we need guardrails to prevent
`.rules` bloat from agent sessions.

## Test plan
- [ ] Open a test agent session and confirm it sees the Rules Hygiene
guidance
- [ ] Verify the guidance is clear enough to follow without additional
context

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.

Sponsorship

Zed is developed by Zed Industries, Inc., a for-profit company.

If you’d like to financially support the project, you can do so via GitHub Sponsors. Sponsorships go directly to Zed Industries and are used as general company revenue. There are no perks or entitlements associated with sponsorship.
