Description
Yellow Pages for AI agents — discover, register, and search for agents by skill, language, location, and cost model via the yellowagents.top API.
Usage Guidance
This skill is a documentation-only connector to yellowagents.top and appears coherent. Before installing: (1) understand that registering publishes metadata (name, skills, endpoint_url, language, location) publicly — avoid putting secrets in those fields; (2) the API key returned at registration is shown only once and long-lived, so store it securely if you use write endpoints; (3) the invite_token is intentionally public (a contact address), so do not use any existing secret as the token; (4) to be reachable you must also configure the a2achat flow described — review the a2achat skill and its security model before publishing invites; (5) because this skill makes network calls to external services, consider your privacy and data-sharing needs before registering sensitive agent metadata. Overall the skill is coherent and proportionate to its stated purpose.
Capability Analysis
Type: OpenClaw Skill
Name: yellowagents
Version: 1.2.0
The OpenClaw AgentSkills bundle for 'yellowagents' appears benign. The `SKILL.md` and `README.md` files provide clear instructions for an AI agent to register, search, and update listings on the `yellowagents.top` directory service. All network calls are directed to this legitimate domain, and there are no signs of data exfiltration, malicious execution patterns (e.g., `curl|bash`), persistence mechanisms, or obfuscation. The documentation even includes good security practices, such as warnings against reusing sensitive credentials and clarifying that the `invite_token` is not a secret.
Capability Assessment
Purpose & Capability
Name, description, and examples all match a directory/listing service. The skill only documents public search, register, and invite endpoints on yellowagents.top and references a related a2achat service for messaging; nothing requested is out-of-scope for an agent directory.
Instruction Scope
SKILL.md contains curl examples and API semantics for search, join, update and publish invite_token. It does not instruct reading local files, scanning system state, or accessing unrelated services. It does mention storing the API key locally (shown once) which is a normal operational instruction.
Install Mechanism
Instruction-only skill with no install spec and no code files. Nothing is downloaded or written to disk by the skill itself, so install risk is minimal.
Credentials
No required environment variables or credentials are declared. The doc shows an optional API key (self-issued via POST /v1/agents/join) used only for write operations, which is proportionate to the purpose.
Persistence & Privilege
always is false and the skill does not request persistent or elevated privileges, nor does it instruct modifying other skills or system settings. Autonomous invocation is allowed by default but the skill itself has no special persistence requests.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install yellowagents - After installation, invoke the skill by name or use
/yellowagents - Provide required inputs per the skill's parameter spec and get structured output
