RFC: Update claude-code-review.yml to use centralized prompt

[evansenter]

Summary

Update the claude-code-review.yml GitHub Action workflows in all repositories to use the centralized review prompt hosted in dotfiles, ensuring consistent code review behavior across all codebases.

Problem / Motivation

The dotfiles repository hosts a sophisticated review prompt at home/.claude/contrib/prompts/claude-review.md with features including:

• Structured severity levels (Critical/Important/Suggestion)
• "Feedback Addressed" comment detection to avoid re-raising resolved issues
• Linked issue checking for PR completeness validation
• Clear verdict rules (REQUEST_CHANGES if any feedback, APPROVE only if perfect)
• Prompt source attribution for traceability

Currently, some repositories still use inline prompts in their workflows, missing these improvements.

Context

• Discovered during: Codebase audit
• Centralized prompt: https://github.com/evansenter/dotfiles/blob/main/home/.claude/contrib/prompts/claude-review.md
• Template workflow: https://github.com/evansenter/dotfiles/blob/main/.github/workflows/claude-code-review.yml

Current Status

Repository	Status
dotfiles	✅ Source of centralized prompt
gemicro	✅ Already uses centralized prompt
rust-genai	❌ Needs update
claude-event-bus	❌ Needs update
claude-session-analytics	❌ Needs update

Proposed Solution

Copy the workflow from dotfiles to each repository that needs updating. The workflow:

1. Fetches the prompt from https://raw.githubusercontent.com/evansenter/dotfiles/main/home/.claude/contrib/prompts/claude-review.md
2. Falls back to a basic inline prompt if fetch fails (with warning comment on PR)
3. Uses the required tools for the prompt to function

Actionable Requirements

#	Requirement	Owner	Blocked By
1	Update rust-genai workflow	Claude	None
2	Update claude-event-bus workflow	Claude	None
3	Update claude-session-analytics workflow	Claude	None
4	Verify workflows trigger correctly on next PR	Human	#1-3

Implementation Checklist

• rust-genai: Replace .github/workflows/claude-code-review.yml
• claude-event-bus: Replace .github/workflows/claude-code-review.yml
• claude-session-analytics: Replace .github/workflows/claude-code-review.yml
• Test by creating a small PR in each repo

Benefits

• Single source of truth: Edit prompt once in dotfiles, all repos pick up changes
• Consistent reviews: Same review criteria across all projects
• Improved feedback loop: Feedback Addressed detection prevents redundant comments
• Traceability: Prompt source link in each review comment

Implementation Complete

Updated all 3 repositories to use the centralized review prompt:

Repository	PR	Status
rust-genai	#247	CI passed (13/13 core tests)
claude-event-bus	#45	CI passed (4/4 core tests)
claude-session-analytics	#33	CI passed (2/2 core tests)

Note: claude-review fails on these PRs because the workflow file is being modified. This is expected behavior documented in the error message: "If you're seeing this on a PR when you first add a code review workflow file to your repository, this is normal and you should ignore this error."

PRs are ready for merge.
