Description
Create cryptographic proofs anchoring your files' exact content and timestamp to the Bitcoin blockchain for immutable, verifiable history.
Usage Guidance
This skill appears to do what it says: it creates and verifies OpenTimestamps proofs for files. Before installing/using it, consider: (1) install the official opentimestamps-client (pip3 install opentimestamps-client) from a trusted environment (verify PyPI/package integrity), because the scripts call the 'ots' CLI; (2) the scripts operate on your local workspace and will create .ots proof files and an .ots-archive directory — add .ots-archive/ to .gitignore if you don't want archives committed; (3) stamping only sends hashes (not file contents) to calendar servers, but those commitments are visible on-chain and multiple files stamped together are linkable as noted in the SKILL.md; (4) network access is required for stamping and verification (calendar servers/Bitcoin), so run these tools where network usage is acceptable. Overall, the package is coherent and proportionate to its purpose.
Capability Analysis
Type: OpenClaw Skill
Name: timestamp
Version: 1.0.0
The OpenClaw Timestamp skill is designed to create and verify cryptographic proofs of file existence using OpenTimestamps and the Bitcoin blockchain. The `SKILL.md` documentation clearly outlines its purpose, emphasizing privacy by stating 'No secrets uploaded. Only hashes leave your machine.' The accompanying shell scripts (`ots-auto-memory.sh`, `ots-stamp.sh`, `ots-verify.sh`) orchestrate the use of the `opentimestamps-client` (installed via `pip3`). These scripts perform file system operations (creating `.ots` proof files, archiving old proofs in `.ots-archive/` directories) and execute external commands (`ots`, `git`, `date`, `find`) strictly within the scope of timestamping and verification. There is no evidence of malicious intent, data exfiltration, persistence mechanisms, or prompt injection attempts against the agent. All actions are transparently aligned with the stated goal of building a verifiable history of files.
Capability Assessment
Purpose & Capability
Name/description (Bitcoin anchoring via OpenTimestamps) matches the provided scripts and SKILL.md. Minor note: the registry metadata lists no required binaries, but the scripts invoke an 'ots' CLI (and SKILL.md tells the user to 'pip3 install opentimestamps-client'), so an ots binary is effectively required.
Instruction Scope
SKILL.md and the scripts operate on local workspace files (MEMORY.md, SOUL.md, memory/*.md). They hash files, archive old .ots proofs, run 'ots stamp' and 'ots verify'. There are no instructions to read unrelated system files, harvest environment secrets, or transmit raw files. Network activity (contacting OpenTimestamps/calendar servers and Bitcoin network via the ots client) is expected and appropriate for the stated purpose.
Install Mechanism
No formal install spec is included (instruction-only). The README directs the user to 'pip3 install opentimestamps-client' which is a typical, low-risk step but does rely on PyPI. This is proportionate to the task; users should verify the pip package source/version before installing.
Credentials
The skill declares no required credentials or config paths. The scripts optionally honor OTS_BIN and WORKSPACE environment variables but do not require secrets or unrelated service keys. No excessive or unrelated environment access is requested.
Persistence & Privilege
The skill is not always-enabled and is user-invocable. It does not modify other skills or system-wide agent configuration. It only creates .ots proof files and local archives in the workspace, which is normal for this functionality.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install timestamp - After installation, invoke the skill by name or use
/timestamp - Provide required inputs per the skill's parameter spec and get structured output
