upstream-audit

upstream-audit is a skill for Claude Code, Codex from maxritter/pilot-shell. It costs 89 tokens per session (2,272 once invoked), scanned C, original, no licence file.

A tool for auditing and updating external packages used by Pilot Shell, including npm, PyPI, Homebrew, and curl-pipe sources. It checks newer stable versions, security advisories, checksums, and whether updates install successfully.

In plain words
What is it for?
Use it to check upstream dependencies, test their installation, and update installer/upstreams.yaml.
Why use it?
It helps find outdated or potentially unsafe dependencies and catches checksum changes before updates are committed.

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 C, and why

upstream-audit scanned grade C with 3 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 2d 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.

Downloads and executes remote codemediumSupply chain

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

# Or: curl -s https://pypi.org/pypi/<name>/json | python3 -c "import sys,json; print(json.load(sys.stdin)['info']['version'])"

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Recursive force deletemediumDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

rm -rf /tmp/upstream-audit-test

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.

upstream-audit is a skill published in the GitHub repository maxritter/pilot-shell (2,066 stars, last pushed 3d ago), with no licence file. It adds 89 tokens to every session and 2,272 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 3 findings (downloads and executes remote code, recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
