Description
Create, manage, and open time capsules โ seal a thought, feeling, decision, or wish and have it delivered back to your future self with AI reflection on what...
Usage Guidance
This skill behaves like a local time-capsule manager: it will write sealed messages and metadata to ~/.openclaw/state/time-capsules.json and create scheduled cron jobs so the agent can open capsules later and run memory searches to compose reflections. Before installing: (1) do not store passwords, private keys, or other secrets in capsules โ the file is plaintext; (2) inspect and control file permissions for ~/.openclaw/state/ and delete any capsules you no longer want retained; (3) confirm you are comfortable with scheduled agent runs (cron jobs) that will autonomously read that file and access your agent memories; (4) if you need stronger privacy, request or implement encryption for the stored file or use a secure storage mechanism instead. If you want, I can suggest an encrypted storage pattern or a checklist of how to audit/remove the cron jobs and capsule file.
Capability Analysis
Type: OpenClaw Skill
Name: timebottle
Version: 1.0.0
The 'timebottle' skill is a well-structured tool for creating and managing 'time capsules' (messages for the future). It uses local storage at `~/.openclaw/state/time-capsules.json` and leverages the system's cron functionality to schedule future agent interactions ('agentTurn') to 'open' the capsules. The logic is consistent with its stated purpose, includes thoughtful handling of sensitive emotional content, and shows no signs of data exfiltration, malicious execution, or unauthorized access.
Capability Assessment
Purpose & Capability
The name/description match the instructions: the skill collects user messages, records metadata, schedules openings, and composes reflections using memory_search. It does not request unrelated credentials, binaries, or services.
Instruction Scope
Runtime instructions are limited to creating/reading/writing ~/.openclaw/state/time-capsules.json, extracting metadata from the message and recent conversation context, calling memory_search when opening, and creating cron jobs that trigger an agent turn. These actions are in-scope for a time-capsule feature, but they give the skill broad discretion to read conversation context and memory_search results when composing reflections.
Install Mechanism
No install steps or external downloads โ instruction-only. Nothing is written to disk by an installer beyond what the skill's runtime instructions specify, which reduces supply-chain risk.
Credentials
The skill stores sealed messages verbatim in a plaintext JSON file under the user's home (~/.openclaw/state/time-capsules.json). While the SKILL.md warns not to store passwords/secrets, the design still places potentially sensitive user text in an unencrypted, persistent file that other local processes or backups could access. It also uses memory_search at open time, which will access the agent's stored memories (expected but privacy-relevant). No environment variables or external credentials are requested, which is proportionate.
Persistence & Privilege
The skill creates persistent artifacts (a JSON file and scheduled cron jobs). It does not set always:true and does not request system-wide privilege changes, but the cron jobs enable future autonomous agent runs that will read the file and call memory_search. This is coherent with the feature but increases the long-term blast radius (persistent data + scheduled agent activity).
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install timebottle - After installation, invoke the skill by name or use
/timebottle - Provide required inputs per the skill's parameter spec and get structured output
