Only one agent example: add a second runtime (Codex / MCP / plain shell) #5

examples/ contains exactly one file — claude-code-stop-hook.json — so the only documented way to wire this memory layer into an agent is Claude Code's hook system. The retrieval path itself (brain_ask.py) is a plain script with no dependency on any particular harness, so this is a documentation gap, not an architectural one.

What "done" looks like

One more example that wires brain_ask.py into a different agent runtime, plus a short examples/README.md saying what each example is and what it assumes. Any of these is fine — pick the one you actually run:

• OpenAI Codex CLI / AGENTS.md
• a plain MCP server exposing recall as a tool
• a bare shell wrapper for people who use neither, so the fallback is documented

Constraints, so this stays reviewable

Keep it to one runtime. An example that was never executed is worse than no example, so paste the actual output you got — even if it is a short one — into the PR description. If you hit a case where brain_ask.py assumes something about its caller that is not written down anywhere (env var, cwd, ordering), that assumption is the more valuable half of this issue: say so, and we will either fix the script or document it.

What you need

A folder of markdown notes and the ability to run brain_ask.py once. The vault does not have to be large — a handful of notes with [[wikilinks]] between them is enough to show recall working.

Comment "claiming this" and it is yours.
