scan

scan is a skill for Claude Code from DevInder1/supply-chain-scanner-public. It costs 79 tokens per session (456 once invoked), scanned A, original, MIT.

A workflow for checking project dependencies such as npm and Python packages for known security flaws.

In plain words
What is it for?
It audits manifests and lockfiles, summarises severity, highlights vulnerabilities listed as actively exploited, and points to remediation reports.
Why use it?
It provides current vulnerability information and ranks findings by the likelihood that attackers could exploit them.

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

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 5d 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.

What it actually says

Project scan

When the user asks to scan a project for vulnerabilities, audit package.json / requirements.txt, or check dependency security:

  1. Call the tridentchain MCP tool scan_project with:
    • project_path = workspace root (absolute path)
    • output_dir = .tridentchain-out
    • run_profile = "full" (live advisory fetch — default)
    • max_findings = 50
  2. Lead with EPSS-prioritised findings. Pull the top-5 by EPSS score from raw_summary.affected_components, ranked by epss_score. These are the actual fix-first list.
  3. Then summarise severity totals (critical / high / medium / low).
  4. If any finding is in the CISA KEV catalog (source: "kev"), tag it clearly — these are actively exploited in the wild.
  5. Point the user at output_paths.epss_remediation_html for the prioritised remediation queue (with copy-paste fix commands).

When to use scan vs siblings

Situation Use
User wants project deps only, live data scan (this)
User is in a hurry / offline quick-scan
User says "system", "IDE", "extensions", "machine", "everything" scan-full
User upgraded packages and wants to verify validate-fixes
User wants to drill into ONE package why
User wants a fix recipe fix-plan

CLI fallback

tridentchain-security --scan project --project-path . --output-dir .tridentchain-out
Changes

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.
