Add agent handoff docs and readiness checks

[EShener]

Hi, Local CLI is a local-first coding-agent repo with safety checks, tools, sub-agents, RAG, desktop UI, and a sizeable test suite, so it looks like a good candidate for a small agent handoff file.

I ran a local dry run with agent-ready against the repo. It estimated readiness at 63/100 -> 96/100 with the team preset.

The useful, repo-specific pieces look like:

• add a compact AGENTS.md that points coding agents to README.md, local_cli/agent.py, local_cli/tools/, local_cli/security.py, local_cli/git_ops.py, local_cli/orchestrator.py, local_cli/sub_agent.py, local_cli/rag.py, and the desktop app under desktop/
• document safe verification commands before PRs, especially python -m unittest discover -s tests for the stdlib test suite and desktop checks when desktop/ changes
• call out safety-sensitive areas so agents are careful around shell execution, path validation, git checkpoints/rollback, environment sanitization, and API-key handling
• add small shims for Claude/Cursor/Gemini/Copilot so different coding-agent tools read the same canonical guidance
• optional CI workflow can run the readiness and test checks consistently

One remaining follow-up from the dry run: the Python package has no explicit lint command. If you intentionally keep the core zero-dependency, the agent instructions can say that tests are the primary required check.

Reproduce without writing files:

npx --yes @eshen_fox_mie/agent-ready improve --preset team --dry-run --format issue

The check is local-only and does not require API keys. If this is useful, I can follow up with a small PR focused only on the handoff docs/CI guidance. If not, feel free to close.
