BF symbiont

Zero-trust AI agent governance for OpenClaw. Adds ORGA runtime, Cedar policy enforcement, SchemaPin tool verification, ClawHavoc skill scanning, and cryptographic audit trails. Use when you need agent governance, security policies, Cedar authorization, MCP tool verification, audit logging, or when scaffolding governed agent projects, scanning skills for malicious patterns, or writing Symbiont DSL definitions.

What is at stake

Medium-severity findings: the skill is probably honest, but read what alarmed the scanner.

Dangerous commands medium severity

Below is the worst case for this category. The finding here is medium: the guard saw a sign, not a proof.

If you install

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.

For the author

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

  1. The text references files that are not there: add them or drop the references.
For the model run — optional
  • 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.

  • 0Tools and files. 4 referenced file(s) missing: references/cedar-patterns.md, references/dsl-guide.md, scripts/audit-log.sh
  • 0Result and completion. Does not say what the result is

  • 70Failures and branches. 7 branches
  • 100Steps. 51 steps
  • 100Consistency. Name and required fields are in place
  • 100Execution cost. Instruction body is 2590 tokens
  • 100Running it twice. Mutating operations check current state
  • 100Progress reporting. Reports progress
  • medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
  • low 11 top-level sections: this looks like several domains in one skill
  • low The response is described with custom markup (4 tags): a typed call is more reliable

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.

Quality signals

  • +5Description has no quoted example phrases that should trigger the skill
  • +4Description does not say when NOT to use the skill (false activations)
  • +3Output format is not stated: the model decides each time
  • +1No license
  • +2Single-language instructions
  • +3Description length 412: enough signal without eating the budget
  • +4Structure: 23 headings
  • +3Step-by-step instructions: 51 items
  • +4Has examples (9 code blocks)

Quality base 70; lint remarks subtract, signals add up to 100. Result: 72.

External checks

ClawHub: clean
This skill is a disclosed security-governance helper that scans skills, adds local policy checks, and writes local audit files; its main caveat is reliance on an external Symbiont runtime not included in the reviewed files.
