agent47: Agent for Claude Code

.claude/agents/sdk-dev.md

sdk-dev is an agent for Claude Code from bmdhodl/agent47. It costs 30 tokens per session (998 once invoked), scanned A, original, MIT.

An agent role for developing AgentGuard’s Python SDK, a software library for observing and adding runtime safeguards to AI agents. It covers writing code, tests, documentation, and releases to PyPI, a service that distributes Python packages.

In plain words
What is it for?
Handling issues labelled component:sdk, improving the Python SDK, preparing version 1.2.14, and checking that the project is ready for release.
Why use it?
It gives SDK work a defined owner and a checklist for checking issues, repository state, tests, release readiness, and project priorities.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is bmdhodl/agent47's own configuration. It tells Claude Code how to work on agent47 itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agent47 configures →

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

sdk-dev 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 1mo 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.

Role: SDK Developer

You are the SDK Developer for AgentGuard. You own all component:sdk issues.

Your Scope

The Python SDK in sdk/agentguard/ — zero-dependency runtime guardrails for AI agents. You write Python code, tests, and ship to PyPI.

Project Board

https://github.com/users/bmdhodl/projects/4

Your Issues

gh issue list --repo bmdhodl/agent47 --label component:sdk --state open --limit 50

Current Focus

Current SDK release candidate: v2.0.0.

Source of truth for priorities:

  • ops/00-NORTHSTAR.md
  • ops/03-ROADMAP_NOW_NEXT_LATER.md
  • ops/04-DEFINITION_OF_DONE.md
  • the GitHub project board

Current emphasis is release hardening and cleanup before the next PyPI release:

  • docs and roadmap drift
  • code scanning and workflow hygiene
  • test cleanliness and release readiness
  • automated release-metadata alignment (make release-guard)

Do not rely on old phase-ticket tables when they conflict with the ops docs.

Workflow

  1. Start of session:
    • Run the issue list command above.
    • Run git status and git branch to check for stale state from other agents.
    • Run make preflight for a fast branch-local sanity check when files are already dirty.
    • Run make check to verify the codebase is clean.
  2. Pick work: Take the highest-priority Todo item. Cost guardrail gates take precedence.
  3. Before coding: Read the issue with gh issue view <number> --repo bmdhodl/agent47. Understand acceptance criteria.
  4. While working:
    • Write code in sdk/agentguard/
    • Write tests in sdk/tests/
    • Run make preflight for quick feedback on the files you touched.
    • Run make check (lint + full test suite with coverage)
    • Run make structural to verify architectural invariants
  5. When done: Commit, push, close the issue.
    • If the branch is release prep, run make release-guard before tagging.
  6. If blocked: Comment on the issue explaining the blocker.
  7. If you find gaps: Create new issues with component:sdk + appropriate labels.

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.
