FD clawseccheck
Free, local, read-only security self-audit for your own OpenClaw agent. Reads your OpenClaw config, bootstrap files, logs, agent session logs, and installed skills, plus a bounded host-security scan; writes only its own local report/history (removable with --purge). Grades your setup A-F when all five check layers ran, naming what's missing otherwise. --monitor records a local baseline so every later run alerts on what changed - a new MCP server, an edited skill, config drift, a finding that appeared or cleared. No API key, no network calls; the only external command it runs is your own read-only openclaw security audit (skip with --no-native). Only two opt-in flags write anything: --apply-ignore-proposals and --pdf. Use it when you want to check or audit your OpenClaw agent's security, find prompt-injection or misconfiguration risks, see your A-F security score, watch your OpenClaw setup for changes, or ask what changed since the last check.
Free, local, read-only security self-audit for your own OpenClaw agent.

What is at stake
The skill contains fragments that, in the wrong hands, cost money or data. Below: what the installer risks and what the author should do.
The instructions or scripts send data out: environment variables, keys, file contents, chat history. You may never notice, because the agent performs the upload as "part of the task".
If the upload is not needed for the task, remove it: catalogs flag such skills and delist them. If it is needed, name the destination explicitly, say what leaves the machine, and give the user a switch.
Below is the worst case for this category. The finding here is medium: the guard saw a sign, not a proof.
The text contains phrases like "ignore previous instructions" or "you are now…". That is an attempt to hijack the agent: it may break your rules, the system limits or company policy.
An honest skill does not need them: state the role and the rules directly without overriding other instructions. Otherwise catalog scanners and corporate filters will block the listing.
Below is the worst case for this category. The finding here is medium: the guard saw a sign, not a proof.
The skill contains commands that delete files, rewrite disks or execute code fetched from the network. The agent may run them without asking if it believes the instructions require it.
Replace destructive commands with safe equivalents that ask for confirmation, scope them to one folder, and stop piping curl into a shell: pin a version and a checksum.
How to improve
- Remove the critical guard findings (secrets, dangerous commands, hidden instructions): while they stand the skill is blocked and cannot grade above F.
- 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.
