Agentic Tools Almanac ☤

The ultimate developer's index for AI coding agents. A community-driven reference for configuring, extending, and intercepting every major agentic development tool. Easily compare lifecycle hooks (e.g., PreToolUse and PostToolUse), built-in capabilities, Model Context Protocol (MCP) servers, system instruction file paths, and customized skills across 40+ different developer agents.

Tools Covered

Legend: ✅ Full = shipped, documented hook system with blocking · ⚠️ = partial or workaround · ❌ = not available · ❓ = unknown

Notes: Warp is primarily a GUI terminal app with an embedded agent (plus a separate oz CLI for headless/cloud use) — included here as a borderline entry, not a pure install-anywhere CLI like the others. Amazon Q Developer CLI is marked unmaintained by AWS as of this writing, with development moved to the closed-source Kiro CLI. Continue was acquired by Cursor/Anysphere in June 2026; its GitHub repo is now read-only. Goose was donated by Block to the Agentic AI Foundation (Linux Foundation) in 2026. Cline, Kilo Code, Junie, Grok Build, Muse Code, DeepSeek Harness, jcode, and QM were added 2026-08-15 as a doc-only pass (sourced from official docs/GitHub, not yet sandbox live-verified like the earlier entries) — several are brand-new (DeepSeek Harness shipped 2 days prior as a v0.1 preview) so expect more ❓s than the older pages; see _shared/source-audit.md. Paseo (added 2026-09-10, doc-only) is an orchestrator, not a coding agent — it launches and supervises other agent CLIs, and is listed here because it has its own config file, lifecycle hooks, MCP server, and skills. Codewhale, Reasonix, oh-my-pi, MiMo Code, Prime Agent, and Tau were added 2026-09-10 as a live-verified pass — all six were installed on the st3ve sandbox (Ubuntu 24.04) and driven through a real multi-step task against the OpenAI API; see each page's "Live Verification" section for what passed, what needed configuration, and what broke.

Azure SRE Agent is a hosted Azure service (configured via the portal or REST API v2), not a local CLI — the "Config format" column reflects its YAML hook schema, and it has no local config file or terminal binary. Its hook surface is limited to Stop and PostToolUse.

Frameworks & SDKs

These are tracked separately from the coding-agent matrices because they are developer frameworks/runtimes rather than end-user CLI agents with a shared hooks/config surface.

Contributing

See _templates/tool-template.md for the standard page format.

When adding or updating a tool:

1. Source everything to an official URL — no guessing.
2. Mark uncertain items with ❓.
3. Use the [official] / [github] / [community] labels in the Sources table.
4. Update the master table in this README.
5. Update _shared/agent-tools-hooks-config.md with the agent's section.

Data Sources & Disclaimer

The Hook Event Cross-Reference table and event counts in the Tools Covered table are sourced directly from each tool's official documentation at the time of last update. Hook APIs evolve rapidly — vendor docs are the authoritative source and should always be consulted before relying on counts or event names listed here. Entries marked ❓ could not be verified against live official documentation at the time of writing.
