What it does
Analyze Release Security Diff is an agent skill from cyberful/cyberful. Deterministically compare bounded offline release manifests to identify artifact, digest, provenance, signer, permission, dependency, and deployment-input changes that alter the reviewed security boundary.
Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files, including scripts, reference files and assets (for example `agents/openai.yaml`, `assets/release-manifest.schema.json` and `assets/release-security-diff-evidence.schema.json`).
It sits in Security. The repository describes itself as: Cyberful is an open-source AI Red Team for discovering, exploiting, verifying, and remediating vulnerabilities. The licence is AGPL-3.0.
When your agent uses it
- Security work in your project
Example prompts
- “/analyze-release-security-diff”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit ec598a6. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 2 files in scripts/ (Python), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Analyze Release Security Diff loads about 477 tokens when it runs, and up to ~708 if it reads all its reference files. Until then it costs about 59 tokens; SKILL.md has 116 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Analyze Release Security Diff
Compare immutable artifact identities and their trust evidence, not version labels alone. Keep source revision, build invocation, provenance, signer, dependency lock, deployment permissions, and destination binding distinct.
Stage scripts/analyze_release_security_diff.py, its manifest, and the example. The analyzer is offline, reads two confined regular JSON manifests, starts no child process, and writes deterministic bounded delta evidence under the output schema.
Read release-diff-method.md before classifying a changed artifact. A changed digest is evidence of different bytes, not evidence of compromise.
Interpret the delta
Separate additions, removals, content changes, provenance changes, signer changes, permission changes, and dependency changes. Escalate reachable trust breaks to audit-build-release-pipelines or audit-software-supply-chain; preserve unresolved collection gaps instead of filling them by inference.
