security-review

security-review is a skill for Claude Code, Codex from makifbaysal/tasktrooper. It costs 41 tokens per session (1,541 once invoked), scanned A, original, Apache-2.0.

A security review is an attacker-focused check of a code change or design. It traces user-controlled input, permissions, data access, outbound requests, secrets, dependencies, and language-model calls to find reachable risks.

In plain words
What is it for?
Use it when changes affect input handling, authentication, queries, files, requests, secrets, dependencies, new endpoints, data flows, or language-model tools.
Why use it?
Security problems often hide in ordinary features such as forms, file handling, queries, or external requests. Focusing on reachable attack paths avoids both missed issues and irrelevant warnings.

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-review scanned grade A with 2 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 8d 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.

Security Review

Overview

Security is not a separate pass over the whole repo — it is one more lens on the diff (code_review) or the design (analysis) you are already reading. Report only what is reachable by an attacker; a theoretical issue with no path to it is noise that trains people to skip your findings.

1. Risk Tier First

  • High — auth, payments, admin actions, file upload, outbound URL fetch, anything that calls an LLM with tool access. Run the full checklist below.
  • Medium — user data, external API calls. Run Injection, Authorization, Exceptional Conditions, Secrets.
  • Low — pure UI, utilities, pure config/copy. Run Secrets and Supply Chain only.

2. Map the Attack Surface (of the diff, not the repo)

List, from the diff: every new input (params, headers, body, path segment, uploaded file, webhook payload, LLM output used downstream), every new or changed query, every auth/authorization check, every outbound call, every secret touched.

3. Report Only Attacker-Reachable Findings

Trace the value to its source with grep_code/expand_symbol_context before flagging it. Not attacker-controlled: config values, environment variables, constants, server-set values, test fixtures. Not a finding: framework auto-escaping doing its job (React {x}, an ORM's parameterized query) — that is the control working, not a gap.

4. Checks

Authorization per new route — does it carry the same middleware as its neighbours, and does the query filter by owner/tenant (IDOR)?

  • ❌ func (h *Handler) GetInvoice(w, r) { id := r.PathValue("id"); inv, _ := h.repo.Get(ctx, id); json.NewEncoder(w).Encode(inv) } — any authenticated user reads any invoice by guessing an id.
  • ✅ inv, err := h.repo.Get(ctx, id); if inv.OrgID != authctx.OrgID(ctx) { return ErrForbidden } — the query result is checked against the caller's scope before it is returned.

Injection sinks — string-built SQL, exec.Command("sh","-c",…) / child_process.exec, template |safe, dangerouslySetInnerHTML, v-html.

  • ❌ db.Exec(fmt.Sprintf("SELECT * FROM tasks WHERE title = '%s'", title))
  • ✅ db.Exec("SELECT * FROM tasks WHERE title = $1", title)

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.

security-review is a skill published in the GitHub repository makifbaysal/tasktrooper (113 stars, last pushed yesterday), licensed Apache-2.0. It adds 41 tokens to every session and 1,541 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 2 findings (makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-05.
