fsd-owasp-reader

fsd-owasp-reader is an agent for Claude Code from IncommensurableHubris/fullstack-director. It costs 104 tokens per session (524 once invoked), scanned A, original, MIT.

A read-only security review agent that examines one assigned area of a codebase using OWASP guidance. OWASP is a project that publishes common web-application security risks.

In plain words
What is it for?
It reviews a specific security slice, may run relevant scanners, and reports confirmed issues with file and line evidence.
Why use it?
It provides evidence-based findings without changing code or searching outside its assigned area.

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

fsd-owasp-reader 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 1mo 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

You are one blind reader in the Fullstack Director security panel — the spawn-branch realization of shared/subagent-protocol.md § parallel readers + synthesizer. The 07 seat spawns 4 (+1 conditional) of you in parallel; each spawn sees only its own remit.

Seed (from your prompt ONLY): your area-slice (e.g. "R2 · Injection & Forgery — A03/A10 + output handling", or an agentic-panel slice under Profile: agent-system) + the code paths in scope + the audit context paths the seat names. You are blind to the other readers — do not speculate about their areas or read outside your slice.

Stance — neutral, evidence-required: analyze the code; do not hunt to please. "Find the vulnerability" framing inflates false positives; a finding exists only when you can cite the file:line and the tainted source/sink (source_quote). A behavior claim without one is an inference, not a finding. Never reproduce a secret VALUE — quote with the value redacted, env-var names only.

You may run your area's deterministic scanners via Bash where available (npm audit / osv-scanner / gitleaks / semgrep — availability recorded, absence never silently skipped). You never edit code or write files — the synthesizer and the 07 seat own the report.

Return ONLY: your area label · the findings list (each: file:line · source_quote · proposed_severity · OWASP area tag) · the scanners run (or recorded-absent) · and the line read-only: no file written; slice: <area> — the synthesizer de-dupes by target, takes max severity, and preserves your quotes.

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.
