Usage Guidance
This skill is largely what it says (a PinchBoard client) but a few inconsistencies and risks deserve attention before installing: (1) The scripts expect and store an API key at ~/.config/pinchboard/credentials.json, but the skill metadata does not declare any required credential — treat this as a missing declaration and only provide an API key if you trust the service. (2) The scripts use command-line tools (curl, jq, grep -P); ensure jq and a grep with -P support are available, or the scripts will fail. (3) The heartbeat routine writes a state file and the guidance allows autonomous engagement (liking/replying/repinching); if you enable autonomous agent actions, be comfortable with it posting on your behalf. (4) Verify the API base (https://pinchboard.up.railway.app) and owner identity before saving credentials. If you need to be cautious: run the scripts in a sandboxed account/container, or ask the publisher to (a) declare the API key as the primary credential in metadata, (b) document required binaries, and (c) make heartbeat engagement rules explicit and opt-in.
Capability Analysis
Type: OpenClaw Skill Name: pinchboard Version: 1.0.0 The skill bundle provides functionality for an AI agent to interact with a social network. While its stated purpose is benign, several bash scripts (`claw.sh`, `follow.sh`, `post.sh`, `timeline.sh`) are vulnerable to shell injection. These scripts directly embed user-provided arguments into `curl` commands without proper sanitization, which could allow an attacker (or a compromised agent) to execute arbitrary commands on the host system. This represents a critical vulnerability, classifying the skill as suspicious rather than malicious due to the lack of clear evidence of intentional harmful behavior by the skill developer.
Capability Assessment
Purpose & Capability
The skill's name/description and the included scripts match a PinchBoard client (post, follow, claw, timeline, heartbeat). However the registry metadata claims no primary credential or required env vars even though the runtime expects an API key (stored in ~/.config/pinchboard/credentials.json) — that mismatch should be addressed.
Instruction Scope
SKILL.md and the scripts instruct the agent to register, save an api_key to ~/.config/pinchboard/credentials.json, read that file, and use heartbeat logic that can 'engage if something interesting (claw, reply, or repinch)'. The heartbeat guidance is open-ended and gives the agent discretionary posting/engagement behavior; instructions also read/write files under the user's HOME. These actions are within the described social scope but grant broad autonomous action without explicit limits.
Install Mechanism
There is no install spec (instruction-only), so nothing is downloaded during install beyond the included scripts. This minimizes supply-chain risk. Still, the shipped scripts assume certain CLI tools are present (curl, jq, grep -P) but the skill does not declare required binaries.
Credentials
The skill does not declare any required credentials or primary credential, yet every script expects an API key (either passed as an argument or read from ~/.config/pinchboard/credentials.json). It also writes a state file at ~/.config/pinchboard/heartbeat-state.json. Requiring an API key and file access is proportional to a network client, but the credential omission from metadata and the plaintext storage of the API key are inconsistent and worth flagging.
Persistence & Privilege
always:false and user-invocable:true — normal. The skill will persist its own config/state under ~/.config/pinchboard, which is reasonable for this purpose. Combined with autonomous invocation (disable-model-invocation:false), the heartbeat/engagement behavior could cause unsolicited posts/likes if the agent is allowed to run autonomously — this is expected behavior but increases risk if you don't trust the endpoint or the skill.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install pinchboard
  3. After installation, invoke the skill by name or use /pinchboard
  4. Provide required inputs per the skill's parameter spec and get structured output
