What is oh-my-vul AGENTS.md?

Repository instructions for oh-my-vul, a local command-line toolkit and collection of skills for vulnerability research. Vulnerability research looks for security weaknesses while keeping investigation evidence-based and reproduction local.

Use them when developing, testing, synchronising shared assets or metadata, and preparing release-related changes in oh-my-vul.

They set boundaries for safe research and explain the project's layout, runtime, and validation commands.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00449	$0.00449
Opus 5	$0.00225	$0.00225
Sonnet 5	$0.00090	$0.00090
Haiku 4.5	$0.00045	$0.00045

Security

Grade A, and why

oh-my-vul AGENTS.md 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 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.

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

Repository Guidance

Purpose

oh-my-vul is a local-first, evidence-driven vulnerability research CLI and Skill collection. Keep research passive and reproduction local. Never weaken evidence gates to make a finding appear report-ready.

Layout

src/cli/: TypeScript CLI, domain workflows, renderers, and Ink TUI.
src/cli/__tests__/: Node test runner coverage for CLI and TUI behavior.
skills/: Canonical distributable Skills and their references, scripts, contracts, and evals.
agents/: Claude Code-specific optional subagent definitions.
contracts/ and shared/: Canonical schemas and assets synchronized into Skills.
scripts/: metadata, asset, packaging, and release validation.
openspec/: local design artifacts; do not archive a change unless explicitly requested.

Development

Runtime baseline: Node.js 22 or later.
Install dependencies with npm install.
Use npm run typecheck for a fast TypeScript check.
Use npm run build && npm test for implementation changes.
Use npm run release:check before release-facing handoff.
Run npm run sync-assets after changing canonical shared assets.
Run npm run sync-metadata after changing package or registry metadata.

Conventions

Preserve deterministic JSON and non-TTY output. Ink must remain TTY-only.
Keep .omv/ research state private and out of source control.
Use sanitized demo-*, example-*, or fixture-* data in tests and docs.
Treat unknown as a valid evidence state; do not infer exploitability or observed results.
Keep Codex and Claude Code setup paths isolated. Codex uses .agents/skills; Claude Code uses .claude/skills and optional .claude/agents.
Update tests, user documentation, and CHANGELOG.md when behavior is user-visible.

Completion

A change is complete when relevant tests pass, generated assets and metadata are synchronized, git diff --check is clean, and release-facing changes pass npm run release:check.

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.
