sca-attacker

A software-composition analysis agent that checks project dependencies for known security vulnerabilities using the OSV database.

In plain words
What is it for?
Use it to read dependency files for npm, PHP, Python, Ruby, and Go projects, resolve package versions, and send up to 100 vulnerability queries per request to OSV.
Why use it?
It removes the need to manually inspect dependency files, resolve their versions, and query vulnerability data one package at a time.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 31 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 901 The whole file, excluding the scripts and references it only reads on demand.

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

sca-attacker scanned grade A with 1 finding 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 yesterday.

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.

OSV API Integration

  • Endpoint: POST https://api.osv.dev/v1/querybatch
  • Request Format:
    {
      "queries": [
        { "package": { "name": "lodash", "ecosystem": "npm" }, "version": "4.17.0" }
      ]
    }
    
  • Batch Size: Max 100 queries per request (recommended)

HTTP Execution

curl -s -X POST https://api.osv.dev/v1/querybatch \
  -H "Content-Type: application/json" \
  -d '{"queries":[{"package":{"name":"lodash","ecosystem":"npm"},"version":"4.17.0"}]}'

Version Resolution Strategy

Pattern Strategy
1.0.0 (exact) Use directly
^1.0.0 (caret) Extract base version (1.0.0)
~1.0.0 (tilde) Extract base version (1.0.0)
>=1.0.0 (range) Extract base version (1.0.0)
*, latest Skip with warning
Lock file available Prefer lock file version

Priority: lock file > exact version > range base

Fallback Strategy

  1. OSV API timeout (10s) → Exponential backoff (3回: 2s, 4s, 8s)
  2. OSV API error → Report as "api-unavailable", continue scan
  3. Offline mode → Not supported (require API)
Attempt Delay Total Wait
1st retry 2s 2s
2nd retry 4s 6s
3rd retry 8s 14s

Max total wait: 14s + timeout (10s) = 24s per batch

Output

Base: {metadata: {scan_id, scanned_at, agent}, vulnerabilities: [{id, type, vulnerability_class, cwe_id, severity, file, line, code, description, remediation}], summary: {total, critical, high, medium, low}} Extra: prefix=SCA, types=vulnerable-dependency, extra_fields={package, version, ecosystem, osv_ids, dev}

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.

sca-attacker is an agent published in the GitHub repository morodomi/dev-crew (1 stars, last pushed 3d ago), licensed MIT. It adds 31 tokens to every session and 901 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
