Install with your agent
Agent handoff
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
New install
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete.
Upgrade existing
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run.

skillsign
Cryptographic signing and verification for agent skill folders using ed25519 keys. Protects your skills from tampering and lets you verify who wrote them.
Install
pip3 install cryptography That's the only dependency. The tool is a single Python file.
Generate a signing identity
python3 skillsign.py keygen python3 skillsign.py keygen --name myagent Creates an ed25519 keypair in ~/.skillsign/keys/. Share the .pub file. Keep the .pem file secret.
Sign a skill folder
python3 skillsign.py sign ./my-skill/ python3 skillsign.py sign ./my-skill/ --key ~/.skillsign/keys/myagent.pem Hashes every file (SHA-256), builds a manifest, signs it with your private key. Creates .skillsig/ inside the folder.
Verify a skill folder
python3 skillsign.py verify ./my-skill/ Detects modified, added, or removed files. Verifies the cryptographic signature. Shows whether the signer is trusted.
Inspect signature metadata
python3 skillsign.py inspect ./my-skill/ Shows signer fingerprint, timestamp, file count, and all covered files with their hashes.
Trust an author
python3 skillsign.py trust ./their-key.pub Adds a public key to your local trusted authors list.
List trusted authors
python3 skillsign.py trusted
View provenance chain (isnād)
python3 skillsign.py chain ./my-skill/ Shows the full signing history — every author who signed the folder, in order.
When to Use
After installing a new skill — verify it hasn't been tampered with Before running untrusted code — check who signed it and whether you trust them Periodically — re-verify your skill folders to detect unauthorized modifications When publishing skills — sign your work so others can verify it came from you When auditing your agent's integrity — run verify on all your skill folders
Example Workflow
# First time: create your identity python3 skillsign.py keygen --name parker # Sign your skills python3 skillsign.py sign ~/.openclaw/skills/my-skill/ # Later: check nothing changed python3 skillsign.py verify ~/.openclaw/skills/my-skill/ # ✅ Verified — 14 files intact. # Signer: ca3458e92b73e432 [TRUSTED] # Someone tampers with a file: python3 skillsign.py verify ~/.openclaw/skills/my-skill/ # ❌ TAMPERED — Files changed since signing: # ~ main.py (modified) # Trust another agent's key python3 skillsign.py trust ./other-agent.pub # View full provenance python3 skillsign.py chain ~/.openclaw/skills/my-skill/ # === Isnād: my-skill/ (2 links) === # [1] ca3458e92b73e432 [TRUSTED] # ↓ # [2] f69159d8a25e8e32 [UNTRUSTED]
