Add Mnemon, Persistent Memory

Installs mnemon in the agent container image. On each container start, mnemon setup registers Claude Code hooks that surface relevant memory before the agent responds and store new insights after each turn. Memory is written to the per-agent-group .claude/ mount and survives container restarts.

Provider Compatibility

mnemon hooks fire only under --target claude-code. Use this skill on agent groups that run the default Claude provider. The provider is the materialized provider key in each group's container.json (absent or claude = default Claude provider). Confirm it before applying:

grep -H '"provider"' groups/*/container.json 2>/dev/null   # no match, or "provider": "claude" = Claude

If a group sets a different provider (e.g. "provider": "opencode"), it spawns its own process and never invokes the claude CLI, so the hooks registered by mnemon setup do not run for that group.

Phase 1: Pre-flight

Check if already applied

grep -q 'MNEMON_VERSION' container/Dockerfile && echo "Already applied" || echo "Not applied"

If already applied, re-run Phase 2 anyway, every step is idempotent and skips work that is already in place, then continue to Phase 3 (Verify).

Check latest mnemon version

curl -fsSL https://api.github.com/repos/mnemon-dev/mnemon/releases/latest | grep '"tag_name"'

Note the version (e.g. v0.1.1), use it as MNEMON_VERSION in the next step.

Phase 2: Apply Changes

1. Dockerfile, install mnemon binary

Insert the mnemon block immediately above the # ---- Bun runtime section of container/Dockerfile (skip if grep -q 'MNEMON_VERSION' container/Dockerfile already matches):
