+# AMP Agent — Continue Reminder
+
+> **PLACEHOLDER** — This reference has not been populated yet because the AMP agent was not active in the originating session.
+
+## Known Differences from Claude
+
+| Aspect | Expected Behavior |
+|--------|-------------------|
+| Rate-limit screen | Unknown; AMP may handle throttling server-side |
+| UI paradigm | Unknown; could be TUI, web UI, or API-driven |
+| Resume command | Unknown |
+| Session model | AMP might use long-running processes or ephemeral workers |
+
+## TODO
+
+1. Clarify what "AMP" refers to in this context:
+   - **Amplify** (AWS)?
+   - **AIX MP** (IBM)?
+   - A proprietary/multi-agent coding harness?
+   - Something else?
+
+2. Determine AMP's runtime environment:
+   - Does it run in a tmux pane?
+   - Is it daemonized?
+   - Does it expose a CLI that can be scripted?
+
+3. If AMP has a resumable terminal session, capture the pane state and record:
+   - Pause / limit indicator text
+   - Keystrokes or commands required to resume
+
+4. Update this file with a concrete example mirroring the Claude reference structure.

+# Claude Code CLI — Continue Reminder
+
+Concrete example: Claude Code CLI running in a tmux pane hits a **session rate limit** and presents a `/rate-limit-options` menu.
+
+## Scenario
+
+- tmux session: `ior`
+- Window: `0`
+- Pane: `0.0` (Claude Code blocked)
+- Message: *"You've hit your session limit · resets 1:10pm (Europe/Sofia)"*
+- Menu option 1: **"Stop and wait for limit to reset"**
+- Resume command after reset: **`continue`**
+
+## What the Blocked Pane Looks Like
+
+```
+  ❯ 1. Stop and wait for limit to reset
+    2. Upgrade your plan
+    3. Upgrade to Team plan
+
+  Enter to confirm · Esc to cancel
+```
+
+## Steps Taken
+
+1. **Capture the pane** to confirm state:
+   ```bash
+   tmux capture-pane -t ior:0.0 -p
+   ```
+
+2. **Create the resume script** at `~/.local/bin/ior-tmux-resume.sh`:
+   ```bash
+   #!/bin/bash
+   set -euo pipefail
+
+   TMUX_SOCKET="/tmp/tmux-$(id -u)/default"
+   TARGET="ior:0.0"
+
+   tmux -S "$TMUX_SOCKET" has-session -t "$TARGET" || {
+       echo "Target pane $TARGET not found"; exit 1;
+   }
+
+   # Select option 1: "Stop and wait for limit to reset"
+   tmux -S "$TMUX_SOCKET" send-keys -t "$TARGET" Enter
+
+   # Wait 5 minutes past the advertised reset time
+   sleep 300
+
+   # Resume the Claude session
+   tmux -S "$TMUX_SOCKET" send-keys -t "$TARGET" "continue" Enter
+   ```
+
+3. **Create the systemd user service** at `~/.config/systemd/user/ior-resume.service`:
+   ```ini
+   [Unit]
+   Description=Resume Claude in ior tmux pane after rate-limit reset
+
+   [Service]
+   Type=oneshot
+   ExecStart=/home/paul/.local/bin/ior-tmux-resume.sh
+   Environment="PATH=/usr/local/bin:/usr/bin:/bin"
+   ```
+
+4. **Create the systemd user timer** at `~/.config/systemd/user/ior-resume.timer`:
+   ```ini
+   [Unit]
+   Description=One-off timer for ior tmux resume at 13:10 today
+
+   [Timer]
+   OnCalendar=2026-06-11 13:10:00
+   AccuracySec=1s
+   Persistent=false
+
+   [Install]
+   WantedBy=timers.target
+   ```
+
+5. **Make executable and enable**:
+   ```bash
+   chmod +x ~/.local/bin/ior-tmux-resume.sh
+   systemctl --user daemon-reload
+   systemctl --user enable --now ior-resume.timer
+   systemctl --user status ior-resume.timer
+   ```
+
+## Verification
+
+Check timer state:
+```bash
+systemctl --user status ior-resume.timer
+```
+
+Expected output:
+```
+  Trigger: Thu 2026-06-11 13:10:00 EEST; 4h 3min left
+  Triggers: ● ior-resume.service
+```
+
+## Key Details
+
+| Item | Value |
+|------|-------|
+| Rate-limit reset time | Shown in the Claude banner (tz-aware) |
+| TMUX socket | `/tmp/tmux-$(id -u)/default` |
+| First keystroke | `Enter` confirms menu option 1 |
+| Buffer sleep | `300` seconds (5 min) past reset time |
+| Resume command | `continue` |
+| Command suffix | `Enter` |
+
+## Caveats
+
+- The `continue` command is specific to Claude Code CLI; other agents use different resume verbs.
+- If Claude changes its rate-limit UI (e.g., adds a countdown instead of a menu), update the first `send-keys` accordingly.
+- `tmux send-keys` injects literal keystrokes; if the pane has scrolled or lost focus, the keys may land in the wrong place. Consider pinning the pane or using `tmux select-pane` first.

+# Codex CLI — Continue Reminder
+
+> **PLACEHOLDER** — This reference has not been populated yet because Codex CLI was not active in the originating session.
+
+## Known Differences from Claude
+
+| Aspect | Expected Behavior |
+|--------|-------------------|
+| Rate-limit screen | May differ; verify by capturing the tmux pane |
+| Menu confirmation | May require `Enter` or a different key |
+| Resume command | Likely **not** `continue`; inspect the prompt text |
+| Session ID | Typically tied to a `codex` tmux session name |
+
+## TODO
+
+1. Capture a Codex rate-limit screen in a tmux pane and record:
+   - Exact prompt text
+   - Available options / key bindings
+   - Reset time format and timezone
+   - Correct resume command (e.g., `resume`, `go`, `y`, etc.)
+
+2. Update this file with a concrete example mirroring the Claude reference structure:
+   - Scenario
+   - Steps Taken
+   - Verification commands
+   - Key Details table
+
+3. Update `../SKILL.md` if Codex requires a fundamentally different approach (unlikely, but possible).

+# OpenCode Agent — Continue Reminder
+
+> **PLACEHOLDER** — This reference has not been populated yet because the OpenCode agent was not active in the originating session.
+
+## Known Differences from Claude
+
+| Aspect | Expected Behavior |
+|--------|-------------------|
+| Rate-limit screen | Unknown; OpenCode may throttle differently |
+| UI paradigm | May be chat-based rather than menu-based |
+| Resume command | Unknown; likely not `continue` |
+| Integration | May run outside tmux (e.g., VS Code extension or standalone binary) |
+
+## TODO
+
+1. Identify how OpenCode signals a pause / rate limit:
+   - Does it print a message in the terminal?
+   - Does it spawn an interactive prompt?
+   - Is there a headless mode that behaves differently?
+
+2. If OpenCode runs in tmux, capture the pane state and record:
+   - Pause / limit indicator text
+   - Required keystrokes to acknowledge
+   - Resume command or hotkey
+
+3. If OpenCode runs outside tmux (e.g., via LSP or IDE), determine whether:
+   - `tmux send-keys` is still viable (IDE integrated terminal)
+   - An alternative IPC mechanism is needed (API, file watcher, signal)
+
+4. Update this file with a concrete example mirroring the Claude reference structure.
