Agent Development Kit is a Python framework for building, evaluating, deploying, and coordinating AI agents as software applications. Developers use it to compose workflows, delegate tasks between specialized agents, manage state, and connect agents to tools while choosing supported models and deployment environments. The catalogue add-ons provide workflows for using the toolkit.
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00138 | $0.01147 |
| Opus 5.5 | $0.00055 | $0.00459 |
| Sonnet 5.5 | $0.00028 | $0.00229 |
| Haiku 4.5 | $0.00014 | $0.00115 |
Grade A, and why
adk-git 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.
How it starts
The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Commit and Pull Request Conventions
Commit message format
Conventional Commits:
<type>(<scope>): <description>
The type decides where the commit lands in CHANGELOG.md. release-please
generates the changelog from merged commit subjects, so the wrong type either
files the change under the wrong heading or drops it from the release notes
entirely.
| Type | Changelog section |
|---|---|
feat |
Features |
fix |
Bug Fixes |
perf |
Performance Improvements |
docs |
Documentation |
refactor, test, build, ci, style, chore |
hidden, no entry |
The mapping lives in .github/release-please-config.json. A type that is not
listed there produces no changelog entry at all.
Scope is optional. Use a short module name with no underscores
(fix(cli):, feat(a2a):, fix(sessions):) or leave it off.
Subject line
Say why the change exists, not which lines moved. A reviewer who reads only the subject should understand the motivation.
| Write | Not |
|---|---|
fix(sessions): prevent duplicate events when resuming HITL |
fix(sessions): check interrupt_id before appending |
feat(workflow): support parallel tool execution |
feat(workflow): add asyncio.gather call in execute_tools_node |
refactor: make graph public for dev UI serialization |
refactor: make graph a public field on Workflow |
Rules:
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.
- 1mo ago First seen · 120 lines · 138 tokens per session scan A 470cf1a18deb
adk-git is a skill published in the GitHub repository google/adk-python (21,864 stars, last pushed today), licensed Apache-2.0. It adds 138 tokens to every session and 1,147 once invoked, about $0.0006 per session on Opus 5.5. 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 2026-08-30.
Other skills, from other repositories
release-notes
Draft a release note section from a commit range, grouped by what the reader gets.
kirocrew-prepare-pr
LOAD THIS FOR EVERY KIRO CREW PR you open or update (Kiro Crew repo only; not other repos or CRs). Runs the whole loop — issue + tier, commit, sync, squash, push, drive CI and AI review to green, fix a red main, arm auto-merge and watch it land (24h). 'push my changes' = prepare-only.
handoff-discipline
Use when ending a session, handing a task back to the user, or approaching the context limit with work unfinished -- the next session or engineer must be able to resume the work instantly.
hook-safety-review
Use when a hook is about to be enabled or modified -- a hook recipe proposed for activation, a pre/post-tool or lifecycle hook added to agent settings, a git pre-commit hook added to a repo, or a third-party hook snippet pasted in from outside.
secret-leak-preflight
Use when about to commit, push, or publish -- staged changes touch config or environment files, generated artifacts (relay sessions, logs, build output) are being added, or the session handled credentials even indirectly.
chinese-commit-conventions
A Chinese-language reference for writing commit messages and changelogs, which record code changes and releases.
