feat: sin code hub — Add missing Go tools (map, grasp, harvest, execute, orchestrate)

[Delqhi]

Description

The sin code unified hub currently only exposes 2 of 7 Go tools. Add the remaining 5.

Current State

sin code --help
Action: review, debt, verify, preflight, codocs, sckg, audit, oracle, adw, ibd, discover, scout, full
# MISSING: map, grasp, harvest, execute, orchestrate

Required Actions

Add to actions_map in src/sin_code_bundle/cli.py:

• map → sin sin-code run map
• grasp → sin sin-code run grasp
• harvest → sin sin-code run harvest
• execute → sin sin-code run execute
• orchestrate → sin sin-code run orchestrate

Also add to sin code full pipeline (after preflight + codocs + debt + sckg):

sin code full .  # Should run: preflight → codocs check → debt → sckg index/hot-paths → map → grasp → harvest → orchestrate

Acceptance Criteria

• sin code map . works
• sin code grasp file.py works
• sin code harvest <url> works
• sin code execute 'cmd' works
• sin code orchestrate works
• All 5 appear in sin code --help
• sin code full includes them in pipeline

Priority

MEDIUM — Completes the Go tool integration in the main workflow hub

[Delqhi]

Not addressed in v3.0.0–v3.2.0 (focus was on the agent loop, verification gate, hooks, slash commands). Remaining work for future release train.

Status (2026-06-12, post-v3.5.0)

Priority: MEDIUM — discovery of what's already there.

Current state (v3.5.0)

The original 'missing Go tools' issue predates v3.x. As of v3.5.0:

• ✅ discover, execute, map, grasp, scout, harvest, orchestrate — all present, all wired in cmd/sin-code/main.go
• ✅ 12 ecosystem skills wired via internal/mcpclient/registry.go
• ✅ 6 verification/analysis tools as external repos (issue [Tech Debt] SIN-Code-Bundle has 7 vendored sub-projects — should be promoted to standalone repos #28)

Remaining gaps

The 'hub' framing — a unified landing page for all tools — isn't there. Currently a user types 'sin-code --help' to see the flat list, but there's no 'sin-code hub' command that groups tools by category (analyze, modify, verify, orchestrate, ...).

Suggested fix

Add 'sin-code hub' (or extend --help with grouping):

• 'sin-code hub list --category analyze'
• 'sin-code hub search query-string'
• Integrates with ECOSYSTEM.md for the full inventory

Cross-refs

• AGENTS.md §10 (CLI subcommand list)
• ECOSYSTEM.md (categorization)
• Sister-issue: docs: Update all README.md files across OpenSIN-Code repos to current state #39 (README propagation)
