prompt-buttons

Purpose

• Standardize how agents present choice-driven prompts so users can respond with one tap.
• Prefer true Telegram inline buttons when channel supports them; otherwise render a compact numbered list as fallback.
• Enforce short labels and one-line option descriptions so menus remain scannable on mobile.

Design rules (enforced by the skill)

• Button label length: 1–3 characters preferred; allow up to 10 chars only when necessary. Examples: Yes, No, 1, 2, A.
• Option descriptions: one sentence / one short clause. Keep each option on a single line.
• Message header: single-line title (question or short instruction).
• Always include buttons metadata in the outgoing message payload. Do not rely on free-text only.
• For menus >6 items, prefer paginated menus (ask user to choose a page) or hierarchical choices (1–3 then deeper options).
• Log the user’s last button-style preference in memory (scope: agent:main) to persist UX.

Capabilities

• Build Yes/No prompts with canonical callback payloads.
• Build numbered menus (1–9) with mapped callback actions.
• Render channel-appropriate fallback text when inline buttons are unavailable.
• Validate button payloads before sending (short labels, callback_data present).
• Optionally include metadata in callback_data (compact JSON base64) for routing back to the calling skill.

API / Integration

• Other skills call prompt-buttons by sending a message via the message tool with action=send and a buttons array in the recommended format.

Recommended payload (Telegram inline buttons): { "action": "send", "channel": "telegram", "message": "Title: Pick an option\n1 — Show top 10 entries\n2 — Triage noisy entries", "buttons": [[ {"text":"1","callback_data":"{"a":"show_top10"}"}, {"text":"2","callback_data":"{"a":"triage"}"} ]] }

Notes on callback_data

• Keep callback_data compact (<=64 bytes recommended for safety across channels).
• When you need to send structured data, encode a short action key and state id (e.g., {\"a\":\"triage\",\"id\":42}), optionally base64-encode if required by the channel provider.
• The skill listening for button presses should expect callback_data and map the short action key back to handler functions.

Fallback rendering (channels without inline button support)

• Produce a numbered list in the message body identical to the button order.
• Example fallback body: "Pick an option:\n1 — Show top 10 entries\n2 — Triage noisy entries\nReply with the number to choose."

Implementation details (for skill authors)

• Use message(action=send, channel=..., message=..., buttons=...) to show the ask.
• Register a callback handler for the channel’s button callbacks (Telegram: listen for callback_query). The handler should:
  1. Parse callback_data.
  2. Acknowledge the callback (Telegram answerCallbackQuery) to remove the loading spinner.
  3. Dispatch to the appropriate internal handler (map action keys to functions).
• When dispatching long-running work from a button press, acknowledge immediately and spawn a background subagent for the task — return a brief confirmation message to the user.

Security & privacy

• Never include raw secrets or tokens in callback_data. Use short opaque identifiers that map to server-side state.
• When storing user preferences (e.g., prefers buttons vs typed replies), store only non-sensitive flags in memory with scope agent:main.

Examples

• Yes/No (implementation): message: "Run self-improving now?\nYes — Run and execute now.\nNo — Not now." buttons: [[{"text":"Y","callback_data":"{"a":"self_imp_yes"}"},{"text":"N","callback_data":"{"a":"self_imp_no"}"}]]

• Multi-step menu (page 1 of 2): message: "Pick what to do next (page 1):\n1 — Show top 10 entries\n2 — Triage entries\n3 — Propose promotions\n4 — Next page" buttons: [[{"text":"1","callback_data":"{"a":"show_top10"}"},{"text":"2","callback_data":"{"a":"triage"}"},{"text":"3","callback_data":"{"a":"promote"}"},{"text":"4","callback_data":"{"a":"page2"}"}]]

Developer notes

• Keep the skill code minimal: message builders + validation + callback dispatch map.
• Include unit tests that validate: button label length, callback_data structure, fallback body matches buttons order.
• Provide an example handler in index.js that demonstrates mapping compact action keys to functions and acknowledging Telegram callback queries.

Installation / discovery

• Place the skill under /data/workspace/skills/prompt-buttons/ and ensure a discovery copy in /data/workspace/skills/skills/prompt-buttons/ so OpenClaw discovers it.
• The skill entry in /data/.openclaw/openclaw.json should be enabled: skills.entries.prompt-buttons.enabled = true.

Compatibility

• Channels with native inline button support: Telegram (full), some webchat adapters (if configured).
• Channels without button support: gracefully fall back to numbered list; the calling skill must accept numeric replies.

Versioning & changelog

• v1.0.2 — Detailed SKILL.md, explicit Telegram inline button guidance, validation rules, and dev notes.
