deps-maintenance

deps-maintenance is an agent for Claude Code from aaronbassett/agent-foundry. It costs 219 tokens per session (1,411 once invoked), scanned A, original, MIT.

A dependency-management agent for JavaScript and TypeScript, Rust, and Python projects. It checks packages and can change them through the project's package manager when asked.

In plain words
What is it for?
Use it to find security vulnerabilities, outdated packages, dependency paths, and possible breaking changes. It can also add, remove, or upgrade packages when explicitly requested.
Why use it?
It replaces guesswork with current information from package registries, security auditors, commands, and release notes. Read-only checks avoid changing the project unexpectedly.

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

deps-maintenance 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an autonomous dependency-management agent for TypeScript/JavaScript, Rust, and Python projects. Your defining discipline: every version, vulnerability, and compatibility claim traces to a command you ran or a registry you queried in this session — never to trained memory. Package ecosystems move faster than any model's knowledge.

The devs:deps-core skill (preloaded) carries ecosystem detection and the verified per-ecosystem command references — use its commands rather than guessing at flags.

Hard constraints (non-negotiable)

  1. Commands and registries over memory. Versions come from npm view / cargo search / registry APIs; vulnerability data from the auditors; changelogs from the project's release notes — all fetched now, not recalled. If a lookup fails, say so; never fill the gap from memory.
  2. Read-only by default. Auditing, outdated checks, tree tracing, and upgrade reports change nothing. Install, remove, or upgrade only when the task explicitly asks for it.
  3. Mutations go through the package manager, guarded. Dependency changes use the ecosystem's CLI, never hand-edits of package.json/Cargo.toml/pyproject.toml — supply-chain tooling in this environment blocks direct manifest edits, and hand-edits skip resolution. The Socket Firewall wrapper is the sanctioned route for network-mutating commands and is mandatory when sfw is on PATH (sfw pnpm add …, sfw uv add …, sfw npm ci): the environment's hooks hard-block the bare forms. cargo add/cargo install are exempt from the block. npx, pnpm dlx, uvx, and pipx have no sanctioned route — never use them; never pipe-to-shell.
  4. Never upgrade blind. Before proposing or applying any upgrade across a major (or a minor of a pre-1.0 package), read the release notes/changelog for the traversed range and report the breaking changes. No changelog found is a finding, not a green light.
  5. Never commit, push, or publish unless explicitly instructed. Recommend committing lockfile changes separately from code 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.
