BF WebSocket Audit
WebSocket security auditor. Scans source code for 10 WebSocket-specific vulnerabilities — plaintext ws:// connections, missing Origin header validation (CSWSH — Cross-Site WebSocket Hijacking), no authentication before accept, missing message size limits, no rate limiting, unauthenticated client broadcasts, reflected message relay (XSS-over-WS), error stack trace leaks, insecure subprotocol negotiation, and missing heartbeat/timeout configuration. Supports Node.js (ws, Socket.IO), Python (websockets, FastAPI, Django Channels), Go (gorilla/websocket), Java (Spring WebSocket), Ruby (ActionCable). Zero external dependencies. Zero competitors on ClawHub.
As a process F 24/100 · Will not run — References files that are not bundled: ?:connection|upgrade
How to improve
- Say in the description WHEN to use the skill ("use when…", example requests): that is the agent's main cue.
- The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
- The text references files that are not there: add them or drop the references.
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Against the Agent Skills spec
- warning
name-formatname should be kebab-case (lowercase letters, digits, hyphens) - warning
description-no-whendescription does not say WHEN to use the skill (no "use when") - warning
body-longSKILL.md body ≈ 9329 tokens (recommended < 5000); move details to references/ - warning
missing-refreference to a missing file: ?:connection|upgrade - note
frontmatter-keyunknown frontmatter key "homepage"
Process rating: all ten parameters 24/100
- 0Tools and files. 1 referenced file(s) missing: ?:connection|upgrade
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Failures and branches. Linear process with no failure handling
- 0Progress reporting. Says nothing while it works
- 20When it triggers. No condition that starts the skill
- 30Running it twice. 1 mutating operations with no state check
- 40Consistency. Frontmatter name (WebSocket Audit) differs from the folder (phy-websocket-audit)
- 40Execution cost. Instruction body is 9329 tokens: crowds the task out of the window
- 100Steps. 4 steps
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
