Add stillrunning supply chain security rules - #356

📝 WalkthroughWalkthroughChangesSupply Chain Security
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟠 High · up to The new rules can allow packages to proceed without a verified clean result, including checking the wrong ecosystem, resolving an unpinned latest version, or bypassing protection during initial setup. This materially weakens the promised supply-chain protection, so the issues should be fixed before merging. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

hard-coded “225k+ known-bad packages” claim and replace it with “Checks packages
against the stillrunning.io threat database.”
In `@rules/stillrunning-supply-chain-security.mdc`:
- Around line 27-33: Update the bootstrap instructions before stillrunning
--install-hook to pin an approved stillrunning version and verify the selected
PyPI artifact hash before running pip install. Make the pre-install check
include the package ecosystem and pinned version, reject non-2xx responses, and
fail closed for UNKNOWN or pending results as well as DANGEROUS and SUSPICIOUS;
allow installation only for an approved CLEAN result.
- Around line 9-19: Update the package-check procedure to send each package’s
name, ecosystem, and exact version, then use a bounded request that surfaces
HTTP, timeout, and parsing failures. Accept installation only for a CLEAN
response matching all requested fields and version; block BLOCKED or DANGEROUS,
require confirmation for SUSPICIOUS, and halt for PENDING, UNKNOWN, missing
fields, or any request failure.

stillrunning.io docs check-package ecosystem version pending BLOCKED DANGEROUS rate limit
💡 Result:
Stillrunning.io is a supply chain security platform that intercepts package manager commands (such as pip, npm, uv, poetry, etc.) to perform security scans before installation [1][2][3]. When using the check-package API endpoint, the service evaluates packages against a live threat database and AI-driven analysis [4][2]. The response typically includes a status field indicating if the package is safe to use [4]. Key states and concepts include: - CLEAN: The package has passed security checks [4][5][6]. - BLOCKED: The package has been identified as malicious (e.g., reverse shells, known malware) or dangerous, and installation is prevented by the platform [4][5][6]. - DANGEROUS: A classification used in scan reports for packages that exhibit high-risk characteristics (such as obfuscated code or known exploit patterns) [5][6]. - Ecosystem: The platform supports multiple ecosystems, including Python (PyPI) and Node.js (npm), and tracks package metadata using version-aware caching keyed by a (package, version) tuple [1][3]. - Rate Limit: While specific rate limits depend on your account tier, the free tier typically has a limited number of daily scans, while paid tiers offer higher or unlimited access [5][6]. - Pending: If a scan request is sent to an asynchronous endpoint (e.g., /api/scan/async), the processing may be queued [3]. For developers, stillrunning can be installed as an always-on hook or used via CLI to scan packages, manage whitelists, and enforce security policies in CI/CD environments [1][7][6]. It is distinct from other tools like Check-Pack or general version-checking MCP servers [8][9]. You can manage configurations, including whether to block dangerous packages or warn on suspicious ones, via local config files (e.g., ~/.stillrunning/config.yaml) or environment variables [5][6].

Make the package check explicit and fail closed.
Send name, ecosystem, and the exact version. Without ecosystem, the endpoint defaults event-stream to pip, so the npm package is not checked in the correct ecosystem. Unversioned requests check latest.
Accept only a matching CLEAN response. Block BLOCKED and DANGEROUS. Require confirmation for SUSPICIOUS. Halt on PENDING, UNKNOWN, HTTP errors such as 429, missing fields, parse errors, and timeouts. Replace curl -s with a bounded request that reports failures.

Search the public web for the official johhnyg/stillrunningrepository,stillrunning.io/agent-setup, the /api/check-packageAPI documentation, and the PyPIstillrunningpackage metadata. Determine the documented installation command, supported package ecosystems and version parameters, possible verdict values includingpendingorBLOCKED, and whether the project documents exact-version pinning or artifact/hash verification.
💡 Result:
The official repository for stillrunning is johhnyg/stillrunning [1]. Installation is documented via the command pip install stillrunning [1]. For general system setup, the site provides a shell-based installer (curl -sSL https://stillrunning.io/install | python3 - --token YOUR_TOKEN) [2], while the agent-setup documentation (stillrunning.io/agent-setup) guides integration with AI coding agents like Claude Code, Cursor, Devin, and Aider [3][4]. The project does not explicitly document an /api/check-package endpoint in its primary repository or PyPI metadata [1][5][6]. The query term /api/check-package is often associated with other developer tooling, such as the Zephex check-package tool [7], or R-based package checklist utilities [8], rather than the stillrunning security agent. Regarding package ecosystems, version parameters, and specific verdict values (e.g., pending, BLOCKED): - The tool is designed to protect Python-based environments (requires Python 3.8+) [1][5]. - While the documentation mentions features like scanning packages, adding to whitelists, and autonomous CI/CD modes [1], there is no public API documentation explicitly defining a /api/check-package verdict schema including 'pending' or 'BLOCKED' status values. - There is no evidence in the official stillrunning documentation confirming that it implements mandatory exact-version pinning or artifact/hash verification as a core documented feature [1][2]. Top results: [1][2][3][7]

Make the bootstrap installation fail closed.
pip install stillrunning runs before stillrunning --install-hook, so the first installation is not protected. Pin an approved version and verify the selected PyPI artifact hash before installation. Include the package ecosystem and version in the pre-install check. Block non-2xx responses, UNKNOWN, and pending; the endpoint returns HTTP 202 with those values, but the rule handles only DANGEROUS, SUSPICIOUS, and CLEAN.

Adds .mdc rules for stillrunning supply chain security.
These rules instruct Cursor to check packages against the stillrunning.io threat database (225k+ known-bad packages) before installing them. Works with both pip and npm.
