Re-add Crush models with --thinking and subscribe hooks to session, turn, and permission events

Crush v0.99.0 speaks Catwalk v3, auto-migrates provider types, and lets hooks follow the whole run. Re-add models with --thinking and --max-attachments, subscribe hooks to session/turn/permission/compaction plus PostToolUse events, and use piped permissions with SIGHUP reload if you host Crush.

Why this loop

Provider type now names the API format (completions, responses, messages), not the vendor; existing openai, openai-compat, and anthropic configs keep working because they migrate on load. New models must use --thinking always|never|toggleable instead of --can-reason, and can set --max-attachments. Hooks are no longer tool-only: they can follow sessions, turns, permissions, compaction, PostToolUse, and PostToolUseFailure, and unknown event names are rejected against the known list, with docs mapping each event to Claude Code. Hosts can theme the TUI, inject open-file context into completions, append text to the next prompt, see which session other clients view, and set CRUSH_PERMISSIONS_PIPED=1 so permission prompts are not asked twice. SIGHUP reloads config instead of stopping the server, http:// aliases tcp://, and shutdown now saves in-progress work. Acting on the new flags and lifecycle hooks is the workflow change; Catwalk v3 itself needs no extra config.

Proposed actions

  1. For each custom Crush model, stop passing --can-reason and re-run: crush model add <provider>/<model> --thinking toggleable --max-attachments 5 (use always or never if you do not want a picker toggle; reasoning levels now show names like X-High)
  2. Add providers by API format, not vendor. OpenAI-compatible: crush provider add <name> --type completions --base-url "<url>" --api-key "$API_KEY" Use --type responses for OpenAI or anything routed through it, and --type messages for Anthropic-compatible APIs. Existing openai/openai-compat/anthropic entries migrate on load.
  3. Update Crush hooks from tools-only to the documented lifecycle events: sessions, turns, permissions, compaction, PostToolUse, and PostToolUseFailure. Match the Claude Code event mapping in the Crush docs exactly—unknown event names are now rejected at load.
  4. If an editor or service hosts Crush, export CRUSH_PERMISSIONS_PIPED=1 so the host answers permission prompts once, push open files as host context so they appear in completions, and append text to the next prompt over the server API instead of starting a run or cluttering chat.
  5. After editing Crush config on a running server, reload without dropping work: kill -HUP <crush-pid> SIGHUP reloads config instead of stopping; http:// is accepted as a tcp:// alias when starting the server.

AGENTS.md / CLAUDE.md / GEMINI.md rule update

DevAgentRadar → Repo Harness Rule Patch

Goal: update our repository's permanent harness instructions based on this release.

Update the file that tool actually reads. Do not dump everything into one file.

  • Claude Code → CLAUDE.md plus .claude/ (skills, hooks, settings, agents, commands). It does not read AGENTS.md natively; start CLAUDE.md with @AGENTS.md.
  • Codex, Copilot, Cursor, Factory Droid, Grok Build, Roo Code, Goose, OpenCode, Amp, Zed, Aider → AGENTS.md.
  • Gemini CLI / Antigravity → GEMINI.md. AGENTS.md only if context.fileName is set.
  • Cursor glob-scoped rules → .cursor/rules/*.mdc (plain .md is ignored), not a second constitution.
  • Codex MCP → .codex/config.toml, not .mcp.json.
  • Copilot extra instructions → .github/copilot-instructions.md; custom agents → .github/agents/.
  • Windsurf → .windsurf/rules (do not assume AGENTS.md).
  • Cline → .clinerules.
  • Procedures → a skill (SKILL.md). Enforcement the model must not skip → a hook. Isolated roles → subagents.
  • Do not fork the same rule into three tool files.

Context

Assistant: Crush Proposal: Re-add Crush models with --thinking and subscribe hooks to session, turn, and permission events Summary: Crush v0.99.0 speaks Catwalk v3, auto-migrates provider types, and lets hooks follow the whole run. Re-add models with --thinking and --max-attachments, subscribe hooks to session/turn/permission/compaction plus PostToolUse events, and use piped permissions with SIGHUP reload if you host Crush.

Why it matters

Provider type now names the API format (completions, responses, messages), not the vendor; existing openai, openai-compat, and anthropic configs keep working because they migrate on load. New models must use --thinking always|never|toggleable instead of --can-reason, and can set --max-attachments. Hooks are no longer tool-only: they can follow sessions, turns, permissions, compaction, PostToolUse, and PostToolUseFailure, and unknown event names are rejected against the known list, with docs mapping each event to Claude Code. Hosts can theme the TUI, inject open-file context into completions, append text to the next prompt, see which session other clients view, and set CRUSH_PERMISSIONS_PIPED=1 so permission prompts are not asked twice. SIGHUP reloads config instead of stopping the server, http:// aliases tcp://, and shutdown now saves in-progress work. Acting on the new flags and lifecycle hooks is the workflow change; Catwalk v3 itself needs no extra config.

Suggested actions

  1. For each custom Crush model, stop passing --can-reason and re-run: crush model add <provider>/<model> --thinking toggleable --max-attachments 5 (use always or never if you do not want a picker toggle; reasoning levels now show names like X-High)
  2. Add providers by API format, not vendor. OpenAI-compatible: crush provider add <name> --type completions --base-url "<url>" --api-key "$API_KEY" Use --type responses for OpenAI or anything routed through it, and --type messages for Anthropic-compatible APIs. Existing openai/openai-compat/anthropic entries migrate on load.
  3. Update Crush hooks from tools-only to the documented lifecycle events: sessions, turns, permissions, compaction, PostToolUse, and PostToolUseFailure. Match the Claude Code event mapping in the Crush docs exactly—unknown event names are now rejected at load.
  4. If an editor or service hosts Crush, export CRUSH_PERMISSIONS_PIPED=1 so the host answers permission prompts once, push open files as host context so they appear in completions, and append text to the next prompt over the server API instead of starting a run or cluttering chat.
  5. After editing Crush config on a running server, reload without dropping work: kill -HUP <crush-pid> SIGHUP reloads config instead of stopping; http:// is accepted as a tcp:// alias when starting the server.

Instructions:

  1. Read the existing context files and settings for the tools in this repo.
  2. Draft an explicit Git diff. Update ONLY agent harness rules or tool configuration.
  3. Call out deprecated flags, obsolete habits, or changed permission boundaries.
  4. Do not touch application logic.

Start with the proposed diff and say which layer and which tool's file it belongs in.

Catwalk v3, hooks!

A big one! Crush now runs on Catwalk v3, hooks can see every part of a run, and editors that host Crush get a whole new set of tools to feel right at home.

Small overview of Catwalk v3:

Crush now speaks Catwalk v3. Provider type describes the API format a provider uses, not who made it:

  • completions: OpenAI-compatible APIs
  • responses: OpenAI, or anything routed through it
  • messages: Anthropic-compatible APIs

Your config is migrated automatically when it loads, so openai, openai-compat and anthropic keep working. No edits needed.

The provider add and model add flags follow along:

crush provider add deepseek \
  --type completions \
  --base-url "https://api.deepseek.com/v1" \
  --api-key "$DEEPSEEK_API_KEY"

crush model add deepseek/deepseek-chat --thinking toggleable --max-attachments 5
  • --can-reason is now --thinking always|never|toggleable
  • --max-attachments N is new
  • Reasoning levels show friendly names in the picker, like "X-High"

Hooks, everywhere 🪝
