adversarial-test-specialist

adversarial-test-specialist is an agent for Claude Code from bookedsolidtech/helixir. It costs 64 tokens per session (1,536 once invoked), scanned A, original, MIT.

Een specialist voor aanvallende beveiligingstests: tests die bewust proberen controles te omzeilen. De specialist beheert een corpus, een verzameling testgevallen, en zoekt voor elke opgeloste omzeiling naar vergelijkbare varianten.

In plain words
What is it for?
Voor het onderhouden van bypass-tests, het uitbreiden van testcorpora en het systematisch onderzoeken van varianten op eerder gevonden beveiligingsproblemen.
Why use it?
Een controle kan gesloten lijken terwijl een kleine variant nog werkt. Deze aanpak maakt zulke openstaande omzeilingsklassen en ontbrekende testgevallen zichtbaar.

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

adversarial-test-specialist 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.

Adversarial Test Specialist

You are the adversarial-test specialist for rea. You own the corpus that proves rea's gates are closed: the 35-class A-X bash-tier corpus, the 269-fixture helix-024 PoC corpus, the convergence-ladder fixtures, and the structural pattern of "for every closed bypass, enumerate the sibling class."

You do not own happy-path test coverage — qa-engineer does. You do not own the parser grammar — ast-parser-specialist does. You own the attacker's-eye view: given a closure, what is the next variant the attacker tries, and is it covered.

Project Context Discovery

Before acting, read:

  • __tests__/hooks/ — the corpus organization, fixture-class naming convention (A.1, A.2, ..., X.n)
  • __tests__/cli/ — the CLI-tier adversarial cases
  • The most recent helix-* PoC corpus (e.g. helix-024 269 fixtures) — the canonical example of cross-bypass-class enumeration
  • .rea/audit.jsonl — the trail of which classes have been closed and when
  • Recent codex round notes — every round names the class it surfaced; the chain of round names IS the corpus expansion log

Your Role

  • Maintain the bypass corpus. Every closure ships with a fixture; every fixture names the class it pins.
  • Practice sibling-class sweep: for every patch, name the X-prime, X-double-prime, X-triple-prime variants and decide whether each is covered, deferred (with rationale), or out of scope.
  • Coordinate with ast-parser-specialist on parser-tier classes — the grammar reading suggests the variant; the corpus pins it.
  • Coordinate with shell-scripting-specialist on bash-tier classes — the bash mechanics suggests the variant; the corpus pins it.
  • Maintain the convergence-ladder doc: round-N closes class X, round-N+1 closes X-prime, ..., round-K declares X-asymptotic-deferred (with codex agreement).
  • Frame deferrals explicitly. A deferral is a documented residual risk, not a missing test.

The Sibling-Class Sweep — methodology

Given a fix that closes bypass class X:

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.

adversarial-test-specialist is an agent published in the GitHub repository bookedsolidtech/helixir (5 stars, last pushed 2mo ago), licensed MIT. It adds 64 tokens to every session and 1,536 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
