# karr-foundation — Periodic Agent Executor for karr Boards

Single-shot daemon that monitors multiple karr boards and runs an agent command
when work is available. Designed for cron/systemd-timer invocation.

## Quick start

```bash
# Config at ~/.config/karr-foundation/config.yml
dirs:
  - /storage/raid/home/getty/dev/perl/dbio-dev/dbio
  - /storage/raid/home/getty/dev/perl/dbio-dev/dbio-postgresql
scan:
  - /storage/raid/home/getty/dev/perl/dbio-dev   # finds dirs with .karr file

# Per-repo .karr file (in each repo root)
command: claude -p "Use karr-coordinator agent, pick next task"
on_idle: skip
drain: true
max_runtime: 1800
max_attempts: 2

# Run via cron every 5 minutes
*/5 * * * * karr-foundation
```

## Config file

Default: `~/.config/karr-foundation/config.yml`

```yaml
dirs:
  - /path/to/repo1
  - /path/to/repo2

scan:
  - /path/to/parent-dir   # finds direct children with .karr file
```

## Per-repo .karr file

Place in repo root. All keys optional. Agent execution is opt-in: a board runs
an agent only if it has `command` **or** `claude: true`. With no agent on any
board, `karr-foundation` prints a read-only overview instead of running
anything (see "Overview").

```yaml
claude: true              # synthesize the canonical claude command (opt-in)
claude_bin: claude        # binary for claude: true (default: claude)
claude_max_turns: 30      # --max-turns for claude: true (default: 30)
claude_permission_mode: bypassPermissions   # (default: bypassPermissions)
prompt: >-                # agent instruction, exposed to the command as $PROMPT
  Use the karr-coordinator skill: pick the next actionable task and move it.
# command: claude -p "$PROMPT"   # explicit command; wins over claude: true
on_idle: skip             # 'skip' (default) | 'always-run'
drain: true               # loop until drained (default) | false for single run
max_runtime: 1800         # seconds: per-command SIGKILL (0 = no timeout)
max_attempts: 2           # stalls on one task before auto-block (default: 2)
max_iterations: 50        # hard cap on drain iterations / drain budget (default: 50)
cooldown_base: 1          # cooldown minutes at level 0 (default: 1)
cooldown_max: 64          # cooldown ceiling in minutes (default: 64)
error_patterns:           # extra case-insensitive substrings → common-error
