Greptile Summary

This PR restructures the agent guidance and skill definitions for the repository by creating a shared AGENTS.md as the single source of truth for all coding agents and converting CLAUDE.md into a thin Claude-specific adapter. Skills previously stored only in .claude/skills/ are moved to a shared skills/ directory with symlinks from both .claude/skills/ and .codex/skills/, making them available to both Claude and Codex without duplication.

• AGENTS.md introduced: All repo guidance (coding standards, PR workflow, git commands, architecture docs) moved from CLAUDE.md to AGENTS.md, with agent-specific language generalized.
• Skills relocated and de-duplicated: Six shared skills moved under skills/ with the legacy review-code skill removed; the reviewloop skill gains a Codex compatibility note and push-authorization clarification.
• clear-caches safety improvement: Default database path changed from the production ~/Library/Application Support/exo/ to the dev .dev-data/data/exo.db.

Confidence Score: 5/5

Safe to merge — all changes are documentation and tooling configuration with no production code touched.

The PR is a pure reorganization of agent guidance and skill definitions. No application logic, database schemas, IPC handlers, or React components were modified. The symlink targets resolve correctly from both .claude/skills/ and .codex/skills/. The one safety-relevant change — defaulting clear-caches to .dev-data/ instead of the production path — is a strict improvement.

No files require special attention.

Important Files Changed

Filename	Overview
AGENTS.md	New shared agent guidance file; content mirrors old CLAUDE.md with multi-agent language improvements and correct ### Python heading hierarchy.
CLAUDE.md	Stripped to a thin adapter that delegates to AGENTS.md and adds four Claude Code-specific notes (skills path, MCP config, permissions, run_in_background).
skills/reviewloop/SKILL.md	Added Codex compatibility note for allowed-tools and push-authorization clarification; otherwise unchanged from prior .claude/ version.
skills/clear-caches/SKILL.md	Default DB path changed from production directory to .dev-data/data/exo.db with an explicit warning not to touch the production path.
skills/electron-devtools-testing/SKILL.md	Claude Code-specific MCP tool names replaced with generic action descriptions and both Claude/Codex MCP install commands added.
skills/github-cli/SKILL.md	Section renamed from Claude Code on Web to Hosted Agent Environments and auth token description softened to accommodate Codex environments.

Reviewloop complete on 174820e.

Fixed all Greptile feedback:

• AGENTS.md: changed the Python heading from H1 to ###.
• skills/reviewloop/SKILL.md: documented Codex handling for Claude-only allowed-tools metadata.
• skills/reviewloop/SKILL.md: clarified that explicit reviewloop invocation authorizes loop pushes; ambiguous invocation still asks once.
• skills/gh-local/SKILL.md: replaced stale tail -50 polling guidance with native long-running session output guidance.

No review issues intentionally left open. Full npm run pre-pr passed for 174820e; Greptile is 5/5 with no files requiring special attention.
