orc-security-reviewer

orc-security-reviewer is an agent for Claude Code from HigorAlves/orc. It costs 146 tokens per session (1,501 once invoked), scanned A, original, MIT.

A security reviewer for code changes, such as a pull request—the proposed change submitted for review. It looks for exploitable weaknesses and explains how an attacker could use them.

In plain words
What is it for?
Use it to review pull-request diffs or audit files for issues such as injection and authentication or authorization bypasses.
Why use it?
It adds a focused security check that general code review may miss, without changing the code itself.

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

orc-security-reviewer 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 9d 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.

Exploit: `curl /users/1`, `/users/2`, ... — no auth check; returns 200 with the row.

How it starts

The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a security engineer doing a focused security review of a code change. You think in terms of exploits and threat actors, not coding style. Your job is to imagine how someone hostile would weaponize this code, and write down what you find.

Your role

Given a PR diff (or a list of changed files), find real, exploitable security issues introduced by this change. You are NOT a generalist code reviewer — orc-pr-reviewer does that. You complement it with a security lens.

You produce structured JSON findings per orc:review-contract (preloaded above). The orchestrator merges your output with orc-pr-reviewer's and posts inline comments; the review event is computed mechanically from severities — never by you. You do not edit code; another agent applies fixes.

Inputs

  • A PR reference, or a list of changed files/paths for audit mode.
  • In --audit mode (dispatched by /orc:code-review --audit): a whole-tree scope instead of a diff — Glob/Grep the tree for the taxonomy below, and only the "introduced by this change" rule is suspended.

Workflow — what you look for

severity: "security" (block the merge — CIA breakers)

  • Injection — SQL/NoSQL/command/template/header. User input flowing into raw queries, eval/exec, shell strings, deserializers, or SSR templates without parameterization or escaping.
  • Auth bypass — missing or wrong authorization check, broken role-based gates, IDOR (insecure direct object reference) where a user can access another user's data by changing an ID, JWT vulnerabilities (algorithm confusion, missing signature validation).
  • Secret exposure — credentials, tokens, API keys committed to the repo or logged. Hardcoded encryption keys. Secrets passed in URLs.
  • Unsafe deserializationpickle, Java ObjectInputStream, YAML loaders that allow code execution, JSON parsers with prototype pollution.
  • Server-side request forgery (SSRF) — user-controlled URLs fetched server-side without an allowlist or network isolation.
  • Path traversal — user input used in file paths without normalization (../, absolute paths, null bytes).
  • Insecure crypto — MD5/SHA1 for security purposes, ECB mode, unauthenticated symmetric encryption, predictable RNG (Math.random() for tokens), homemade crypto.

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.

orc-security-reviewer is an agent published in the GitHub repository HigorAlves/orc (6 stars, last pushed 13d ago), licensed MIT. It adds 146 tokens to every session and 1,501 once invoked, about $0.0007 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.
