security-scan

security-scan is a command for Claude Code, OpenCode from affaan-m/ECC. It costs 16 tokens per session (641 once invoked), scanned A, original, MIT.

A command that scans an agent project or selected path for security issues involving permissions, hooks, MCP servers, and secrets. It produces findings in formats such as text, JSON, Markdown, or HTML.

In plain words
What is it for?
Use it to scan a project or .claude directory, filter findings by severity, generate CI or review reports, and apply only fixes marked safe.
Why use it?
It helps uncover risky configuration and runtime surfaces, then separates scanner results from suggested follow-up work.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

security-scan scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Security Scan Command

Run AgentShield against the current project or a target path, then turn the findings into a prioritized remediation plan.

Usage

/security-scan [path] [--format text|json|markdown|html] [--min-severity low|medium|high|critical] [--fix]

  • path (optional): defaults to the current project. Use a .claude/ path, a repo root, or a checked-in template directory.
  • --format: output format. Use json for CI, markdown for handoffs, and html for standalone review reports.
  • --min-severity: filters lower-priority findings.
  • --fix: applies only AgentShield fixes explicitly marked as safe and auto-fixable.

Deterministic Engine

Prefer the packaged scanner:

npx ecc-agentshield scan --path "${TARGET_PATH:-.}" --format text

For local AgentShield development, run from the AgentShield checkout:

npm run scan -- --path "${TARGET_PATH:-.}" --format text

Do not invent findings. Use AgentShield output as the source of truth and separate scanner facts from follow-up judgment.

Review Checklist

  1. Identify active runtime findings first:
    • hardcoded secrets
    • broad permissions
    • executable hooks
    • MCP servers with shell, filesystem, remote transport, or unpinned npx
    • agent prompts that handle untrusted content without defenses
  2. Separate lower-confidence inventory:
    • docs examples
    • template examples
    • plugin manifests
    • project-local optional settings
  3. For each critical or high finding, return:
    • file path
    • severity
    • runtime confidence
    • why it matters
    • exact remediation
    • whether it is safe to auto-fix
  4. If --fix is requested, state the planned edits before applying fixes.
  5. Re-run the scan after fixes and report the before/after score.

Output Contract

Return:

  1. Security grade and score.
  2. Counts by severity and runtime confidence.
  3. Critical/high findings with exact paths.
  4. Lower-confidence findings grouped separately.
  5. A remediation order.
  6. Commands run and whether the scan was local, CI, or npx-backed.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
