功能描述

Audit GitHub Actions workflow cache usage for poisoning, keying, and secret-path risks.

使用说明 (SKILL.md)

GitHub Actions Cache Hardening Audit

Use this skill to statically audit .github/workflows/*.yml for risky cache patterns that can cause cache poisoning, stale cache churn, or secret leakage.

What this skill checks

actions/cache usage on untrusted triggers (pull_request_target)
Cache keys that do not use hashFiles(...)
Overly broad restore-keys prefixes
Sensitive paths accidentally included in cache paths (.aws, .ssh, .npmrc, .git)
Floating cache action refs (@main, @master)

Inputs

Optional:

WORKFLOW_GLOB (default: .github/workflows/*.y*ml)
TOP_N (default: 20)
OUTPUT_FORMAT (text or json, default: text)
WARN_SCORE (default: 3)
CRITICAL_SCORE (default: 6)
WORKFLOW_FILE_MATCH (regex, optional)
WORKFLOW_FILE_EXCLUDE (regex, optional)
FAIL_ON_CRITICAL (0 or 1, default: 0)

Run

Text report:

WORKFLOW_GLOB='.github/workflows/*.yml' \
bash skills/github-actions-cache-hardening-audit/scripts/cache-hardening-audit.sh

JSON output + fail gate:

WORKFLOW_GLOB='.github/workflows/*.yml' \
OUTPUT_FORMAT=json \
FAIL_ON_CRITICAL=1 \
bash skills/github-actions-cache-hardening-audit/scripts/cache-hardening-audit.sh

Run against bundled fixtures:

WORKFLOW_GLOB='skills/github-actions-cache-hardening-audit/fixtures/*.yml' \
bash skills/github-actions-cache-hardening-audit/scripts/cache-hardening-audit.sh

Output contract

Exit 0 by default (report mode)
Exit 1 when FAIL_ON_CRITICAL=1 and at least one critical workflow is detected
Text mode prints a summary and top flagged workflows
JSON mode emits summary, flagged_workflows, and critical_workflows

安全使用建议

This skill appears to be what it claims: a static linter for GitHub Actions cache usage. Before running it, review the script (already bundled) and run it against a restricted glob (default .github/workflows/*.y*ml) or against included fixtures to confirm output. It reads files matched by the glob—so avoid pointing it at broader globs if you don't want unrelated files scanned. There's no network exfiltration or credential access in the code, and it does not require any installation. If you plan to run it in a CI runner with broad filesystem access, be aware it will read files available to that runner; use WORKFLOW_GLOB to limit scope. If you need higher assurance, run the script locally on a copy of the repository or review the bundled code (scripts/cache-hardening-audit.sh) line-by-line; otherwise this skill is coherent and proportionate to its stated purpose.

功能分析

Type: OpenClaw Skill Name: github-actions-cache-hardening-audit Version: 1.0.0 The skill is a static analysis tool designed to audit GitHub Actions workflows for cache-related security risks, such as cache poisoning on untrusted triggers or the accidental caching of sensitive directories like .ssh or .aws. The logic is implemented in a transparent Python script (embedded in scripts/cache-hardening-audit.sh) that scans local YAML files for risky patterns. No evidence of data exfiltration, malicious execution, or prompt injection was found.

能力评估

✓ Purpose & Capability

Name/description align with the included Bash+Python script which scans .github/workflows YAML files for cache-related anti-patterns. Required binaries (bash, python3) are exactly what the script needs. No unrelated credentials, binaries, or install steps are requested.

✓ Instruction Scope

SKILL.md instructs running the bundled script against workflow files (default .github/workflows/*.y*ml). The script only reads files matched by the provided glob, parses them for specific patterns, and emits text or JSON. It does not call external network endpoints, does not access environment variables beyond those declared, and does not exfiltrate data. Note: because it reads repository files, running it in a context with broader filesystem access could expose any files matched by the glob—this is expected for a static repo scanner.

✓ Install Mechanism

There is no install spec; this is instruction-only with a bundled script. That minimizes risk since nothing is downloaded or written to disk beyond the existing skill files.

✓ Credentials

The skill requires no environment variables or credentials. The optional runtime inputs (WORKFLOW_GLOB, OUTPUT_FORMAT, etc.) are reasonable for a static analysis tool and do not request secrets or unrelated access.

✓ Persistence & Privilege

always:false and no behavior that modifies agent/system configuration. The skill does not attempt to persist credentials or change other skills. Autonomous invocation is allowed by default but is not combined with other concerning behaviors.
