sdk-dev

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.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

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 yesterday.

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 observability and runtime guards for AI agents. You write Python code, tests, and ship to PyPI.

Project Board

Your Issues

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

Current Focus

Current SDK release candidate: v1.2.14.

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.

sdk-dev is an agent published in the GitHub repository bmdhodl/agent47 (4 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 952 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
