Snider e90a84eaa0 feat: merge go-agent + go-agentic + php-devops into unified agent repo
Combines three repositories into a single workspace:
- go-agent → pkg/orchestrator (Clotho), pkg/jobrunner, pkg/loop, cmd/
- go-agentic → pkg/lifecycle (allowance, sessions, plans, dispatch)
- php-devops → repos.yaml, setup.sh, scripts/, .core/

Module path: forge.lthn.ai/core/agent

All packages build, all tests pass.

Hook Output Policy

Consistent policy for what hook output to expose to Claude vs hide.

Principles

Always Expose

Category Example Reason
Test failures FAIL: TestFoo Must be fixed
Build errors cannot find package Blocks progress
Lint errors undefined: foo Code quality
Security alerts HIGH vulnerability Critical
Type errors type mismatch Must be fixed
Debug statements dd() found Must be removed
Uncommitted work 3 files unstaged Might get lost
Coverage drops 84% → 79% Quality regression

Always Hide

Category Example Reason
Pass confirmations PASS: TestFoo No action needed
Format success Formatted 3 files No action needed
Coverage stable 84% (unchanged) No action needed
Timing info (12.3s) Noise
Progress bars [=====> ] Noise

Conditional

Category Show When Hide When
Warnings First occurrence Repeated
Suggestions Actionable Informational
Diffs Small (<10 lines) Large
Stack traces Unique error Repeated

Implementation

Use output-policy.sh helper functions:

source "$SCRIPT_DIR/output-policy.sh"

# Expose failures
expose_error "Build failed" "$error_details"
expose_warning "Debug statements found" "$locations"

# Hide success
hide_success

# Pass through unchanged
pass_through "$input"

Hook-Specific Policies

Hook Expose Hide
check-debug.sh Debug statements found Clean file
post-commit-check.sh Uncommitted work Clean working tree
check-coverage.sh Coverage dropped Coverage stable/improved
go-format.sh (never) Always silent
php-format.sh (never) Always silent

Aggregation

When multiple issues, aggregate intelligently:

Instead of:
- FAIL: TestA
- FAIL: TestB
- FAIL: TestC
- (47 more)

Show:
"50 tests failed. Top failures:
- TestA: nil pointer
- TestB: timeout
- TestC: assertion failed"
