Description
Automatically solves Moltbook math captchas by parsing English text, extracting operations, calculating results, and formatting answers with two decimals.
Usage Guidance
This skill appears to do what it claims (solve Moltbook math captchas and call Moltbook's API), but it reads a credentials file from ~/.config/moltbook/credentials.json and sends a POST to https://www.moltbook.com/api/v1/verify — neither of these are declared in SKILL.md or the skill metadata, and SKILL.md even claims a different dependency (memory/moltbook-state.json). Before installing or enabling this skill, consider: 1) Ask the developer to update SKILL.md and the manifest to explicitly declare the config path and required credential (what field name is expected in the file). 2) Inspect the credentials file and confirm it only contains the minimal API key the skill needs (avoid storing other secrets there). 3) If you don't trust the skill, do not provide your Moltbook API key; run it in an isolated/test account or environment first. 4) If you need stricter control, disable autonomous invocation for the agent or require manual confirmation before verification calls. 5) If you want to proceed, request the developer change the skill to read from the declared memory/moltbook-state.json or to accept the key via an explicitly-declared env/config interface so permission and auditing are clear.
Capability Analysis
Type: OpenClaw Skill
Name: molt-solver
Version: 1.0.0
The skill is suspicious due to its direct access and transmission of sensitive user credentials. The `molt-solver.ts` file reads `api_key` from `~/.config/moltbook/credentials.json` and transmits it to `https://www.moltbook.com/api/v1/verify`. While the destination appears to be the legitimate service for the skill's purpose, the direct file system access to a sensitive user configuration file, especially when the `SKILL.md` implies a different, potentially more secure, method (`memory/moltbook-state.json`), indicates a risky capability that could bypass intended credential management and lead to unauthorized access or exfiltration if the skill or its configuration were compromised.
Capability Assessment
Purpose & Capability
The name and files indicate a solver for Moltbook verification challenges, which aligns with the implementation: solveChallenge parses English-number words and verify() posts an answer to Moltbook's API. That capability is plausible for the stated purpose.
Instruction Scope
SKILL.md claims the skill depends on memory/moltbook-state.json for account context and documents a /molt verify command, but the TypeScript code reads ~/.config/moltbook/credentials.json (CRED_PATH) and performs a network POST to https://www.moltbook.com/api/v1/verify. The SKILL.md does not disclose reading a credentials file or making network calls; those are runtime actions that should be declared and justified.
Install Mechanism
No install spec — the package is instruction/code-only. That is low-risk in the sense that nothing external is downloaded at install time. The included code will run when invoked by the agent.
Credentials
The skill does not declare any required environment variables or config paths, yet the code reads the user's home config file (~/.config/moltbook/credentials.json) and expects an api_key inside. SKILL.md instead references memory/moltbook-state.json — this mismatch means the skill will access sensitive local credentials without declaring or justifying that access.
Persistence & Privilege
always is false and the skill is user-invocable; autonomous invocation is allowed (platform default). While not privileged by manifest flags, the ability to read local credentials and call an external API increases its effective privilege and blast radius if invoked autonomously.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install molt-solver - After installation, invoke the skill by name or use
/molt-solver - Provide required inputs per the skill's parameter spec and get structured output
