Lifecycle Hooks

This skill defines behavioral rules and lifecycle event handlers converted from the core-tools hook configuration. These rules describe when certain operations should be automatically approved or handled without user intervention.

Auto-Approve Deep Analysis Session Operations

Trigger: Before any file write, file edit, or shell command execution.

Matcher: Operations targeting Write, Edit, or shell commands.

Behavior: Automatically approve file operations that target deep-analysis session and cache directories. All other operations pass through to the normal permission flow.

Approved Paths

The following directory patterns are auto-approved for file operations:

Pattern	Description
.agents/sessions/__da_live__/*	Active deep-analysis session files
.agents/sessions/exploration-cache/*	Exploration cache (cached analysis results)
.agents/sessions/da-*/*	Archived deep-analysis sessions

Logic

1. For file write/edit operations: Extract the target file path. If it matches any of the approved path patterns above, approve the operation automatically.
2. For shell commands: Check if the command string contains any of the approved directory paths. If so, approve automatically.
3. For all other operations: No opinion — let the normal permission flow handle it.

Implementation Reference

See references/auto-approve-da-session.sh for the reference shell implementation of this auto-approval logic. The script:

• Reads tool input as JSON from stdin
• Extracts the tool name and relevant parameters (file path or command)
• Matches against the approved path patterns
• Returns an approval decision or exits silently (no opinion)
• Never exits with a non-zero status code (a non-zero exit would break the permission flow)

Debug Logging

The reference implementation supports optional debug logging:

• Set environment variable AGENT_ALCHEMY_HOOK_DEBUG=1 to enable
• Logs are written to the path in AGENT_ALCHEMY_HOOK_LOG (default: /tmp/agent-alchemy-hook.log)

Integration Notes

What this component does: Defines lifecycle event handlers that auto-approve file operations targeting deep-analysis session directories, enabling autonomous execution during analysis workflows without manual permission grants.

Capabilities needed: Pre-action hook/interceptor system that can inspect file operation targets and approve them programmatically. The host platform must support a way to intercept file writes and shell commands before execution.

Adaptation guidance: The auto-approval logic is straightforward path matching. On platforms without a hook system, this can be implemented as: (1) a pre-configured allow-list of directory patterns, (2) a middleware that checks file operation targets, or (3) a configuration setting that grants write access to session directories. The reference shell script in references/ shows the exact matching logic.

Configurable parameters: None (the approved paths are tied to the deep-analysis session directory structure).
