High-risk patterns in Claude Code Agent Skills (SKILL.md): auto-approved shell, pre-model dynamic-context execution,….

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Trustabl Pre-Coding: Claude Agent Skill safety

<!-- generated: 2026-01-01 | rules: 0000000000000000000000000000000000000000 | schema: 1 | sdks: claude_skill | template: 3 -->

Before writing any SKILL.md, you MUST apply every constraint below. Rules are
ordered by severity. A violation here will fire the corresponding finding
in post-build scan — prevent it now.

## Tool Grant Decision Tree

1. Does this skill need shell commands?
   YES → specify exact prefixes: Bash(git status *) — never bare Bash or Bash(*)
   NO  → omit Bash entirely

2. Does allowed-tools include any of: Bash / Write / Edit / WebFetch / NotebookEdit?
   YES → set disable-model-invocation: true
   NO  → disable-model-invocation may be false (read-only skills are safe to auto-invoke)

## [CSKILL-003] Dynamic-context command performs network egress or reads secrets
**Severity:** critical | **Confidence:** 0.85

**Directive:** Remove the network and credential access from dynamic-context commands entirely.

**Why:** A dynamic-context command in this skill performs network egress (curl / wget / nc / …) or reads credentials/secrets (gh auth, $AWS_*, ~/.aws, ~/.ssh, id_rsa, *_key, …).

How to install

The exact contents, by fingerprint
mdr add trustabl/agent-reliability-analyzer/claude-skill-safety@sha256:db6683fd715cae5f

The line at the top of this page pins the label git:20261006.de6a241, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
