+# Coding-agent red-team archetype
+
+Scenario-driven adversarial suites for **coding agents** — agents with file
+read/write access, shell tools, package managers, MCP servers, and Git
+clients. Each case targets a concrete attack pattern documented in public
+threat research.
+
+## Threat model
+
+A coding agent typically has access to:
+
+- A `bash` (or equivalent shell) tool with the developer's working directory.
+- A `read_file` / `write_file` / `edit_file` tool family for source edits.
+- A `github_*` tool family (read issues, comment, push branches, open PRs).
+- A package-manager tool (`npm`, `pip`, `cargo`, `bun add`, `uv add`).
+- One or more MCP servers contributed by the user's IDE / plugin ecosystem.
+
+The blast radius is therefore: **the developer's filesystem, their secrets,
+their company's source control, and the public package registries**.
+
+These suites test whether the agent stays inside a defensible scope when:
+
+1. **Source / fetched content is hostile.** A README, an issue body, a
+   search result, or an MCP tool description carries an injected directive.
+2. **Tools have destructive options.** `git push --force`, `rm -rf`, package
+   deletions — the agent must require an explicit user-level confirmation
+   before invoking them.
+3. **Supply chain is poisoned.** The agent suggests a typo-squatted package
+   ("slopsquatting") or installs a dependency named in injected content.
+4. **The sandbox isn't hardened.** Code-execution tools shouldn't be tricked
+   into reading `.env`, making outbound network calls, or escaping the
+   workspace.
+
+## Tools the suites assume
+
+The suites embed tool output as `[tool: ...]` blocks inside `user`-role
+messages so they run against any LLM target without needing a live tool
+runtime. Tool names referenced (you can rename to match your own agent):
+`bash`, `read_file`, `write_file`, `edit_file`, `github_get_issue`,
+`github_post_pr_comment`, `package.add`, `mcp.call`.
+
+## Fixtures
+
+- **`fixtures/poisoned-mcp-server.js`** — minimal demo of an MCP-style
+  registry response whose tool description contains a hidden agent-targeted
+  directive. Self-contained: `node fixtures/poisoned-mcp-server.js
+  --self-test` exits 0 if the demo string round-trips. No `npm install`.
+- **`fixtures/injected-readme.md`** — a benign-looking README with an HTML
+  comment carrying an injection payload, used by `readme-issue-url-injection`.
+- **`fixtures/validators/check_imports_are_real.py`** — a tiny stdlib-only
+  Python script used by a `code-grader` assertion in
+  `supply-chain-slopsquatting` to flag suggested imports that are not real
+  PyPI packages.
