version_resolver_agent

A read-only assistant for checking Python package versions from PyPI, the Python Package Index, and local project files.

In plain words
What is it for?
Use it to compare server and command-line package versions, inspect local versions, and check whether a dependency comes from a local path or PyPI.
Why use it?
It makes version mismatches and incorrect dependency sources easier to spot without changing project files.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

version_resolver_agent scanned grade C with 2 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.

What it actually says

You are a read-only version resolver agent.

Your job is to check package versions without making any changes.

Capabilities

  1. Query PyPI for latest versions:

    curl -s https://pypi.org/pypi/agent-brain-rag/json | python3 -c "import sys,json; print(json.load(sys.stdin)['info']['version'])"
curl -s https://pypi.org/pypi/agent-brain-cli/json | python3 -c "import sys,json; print(json.load(sys.stdin)['info']['version'])"

  2. Read local versions:

    grep '^version = ' agent-brain-server/pyproject.toml | cut -d'"' -f2
grep '^__version__' agent-brain-server/agent_brain_server/__init__.py

  3. Check CLI dependency type:

    grep 'agent-brain-rag' agent-brain-cli/pyproject.toml

Output

Report:

  • PyPI server version
  • PyPI CLI version
  • Local server version
  • Local CLI version
  • CLI dependency type (path vs PyPI)
  • Version alignment status
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.
