Problem: Long OMP sessions produce cognitive loops — “optimizing the wrong problem”, attachment to results (Gita), fear vs clarity, or drifting from long-term goals. Full retros (clock-aligned or break-time) cost too much context; need lightweight 30-second reorientation nudges injected as steer messages.

Solution: @ankitg12/agent-suggester Pi extension. Loads via omp plugin link (not marketplace). Registers ExtensionAPI factory that subscribes to session_start, tool_call, before_agent_start, agent_end, session_shutdown. Schedules setTimeout(fire, intervalMs) on every session start (session-relative by default).

Install (ghq + link):

ghq get https://github.com/ankitg12/agent-suggester-omp
omp plugin link $(ghq list ankitg12/agent-suggester-omp)

Manifest in package.json:

"pi": { "extensions": ["./agent-suggester.ts"] }

Config (~/.omp/agent/agent-suggester.json):

{
  "intervalMs": 900000,
  "clockAlign": false,
  "picker": "random",
  "skipIfIdle": true,
  "wrapWith": "🔄 **Suggestion** — a 30-second pause invited\n\n{item}\n\n*If this shifts something, say so and we'll adjust. Otherwise continue — no analysis needed.*",
  "items": [
    "Are you solving the right problem, or optimizing the wrong one?",
    ...
    "This too shall pass."
  ]
}

loadConfig validates non-empty string[] items, falls back to defaults, logs to agent-suggester.log.
If absent or invalid → early return, extension idle.

Scheduling & injection:

session_start → toolCallCount=0, rotationIndex=0, scheduleNext() (delay = intervalMs or nextBoundary if clockAlign).
fire(): skip if paused or (skipIfIdle && toolCallCount===0); pick item, resolveItem (strip YAML frontmatter if ~/path), pi.sendUserMessage(message, {deliverAs:"steer"}), scheduleNext().
Sleep detector: setInterval watching Date.now() delta > 2× poll → reschedule.
before_agent_start (if nudgeJustFired): save ctx.ui.getEditorText(); agent_end: restore via setEditorText.
Commands: /suggester-pause, /resume, /now (immediate random/rotate pick + steer, no timer).

Evidence (2026-06-21 session):

01:05:35 nudge received with item[0] + exact wrapWith.
suggester.log: “session_start — armed timer” (no idle path). Why it works: steer injection bypasses normal turn; draft save prevents editor loss; skipIfIdle avoids noise on idle segments; random vs rotate picker; 9+ curated items (Stoic, Gita, first-principles).
