Snider 61e01bfdf1 feat: initial go-agent — agentci + jobrunner + plugins marketplace
Consolidates three codebases into a single agent orchestration repo:

- agentci (from go-scm): Clotho dual-run verification, agent config,
  SSH security (sanitisation, secure commands, token masking)
- jobrunner (from go-scm): Poll-dispatch-report pipeline with 7 handlers
  (dispatch, completion, auto-merge, publish draft, dismiss reviews,
  send fix command, tick parent epic)
- plugins marketplace (from agentic/plugins): 27 Claude/Codex/Gemini
  plugins with shared MCP server

All 150+ tests passing across 6 packages.

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"
