Context

OpenSIN-Code/autodev-cli v0.4.0 (Python, MIT) was already wired into the
SIN-Code WebUI v2 via lib/sin/mcp.ts:getAutodevTools(), but the Go
sin-code binary itself had zero autodev references — gh search code 'autodev' repo:OpenSIN-Code/SIN-Code returns 0 hits. This PR completes
the integration on the Go side as a Bridged-External sibling.

What changes

  • cmd/sin-code/internal/autodev/ — stdlib-only bridge package
    (DefaultBin / IsInstalled / ResolveAutodevBin /
    ResolveAutodevMCPBin / Version). 11 hermetic tests, all green
    under go test -race.
  • cmd/sin-code/autodev_cmd.goNewAutodevCmd cobra constructor
    with setup / doctor / version subcommands. Pattern mirrors
    gh_cmd.go (Bridged-External-Contract, M4 + v3.8.0+).
  • cmd/sin-code/internal/mcpclient/registry.go — registers
    {Name: "autodev", Transport: "stdio", Command: "autodev-mcp"} so
    sin-code serve and sin-code chat spawn autodev-mcp as a Python
    stdio MCP sibling.
  • cmd/sin-code/internal/permission_defaults.go — 7 split M4 rules
    (read-only → allow, mutating → ask, catch-all → ask).
  • ECOSYSTEM.md + requirements-ecosystem.txt — atomic sync per the
    ecosystem-sync CI gate.

Quality gates (all green locally)

  • CGO_ENABLED=0 go build ./... exit 0
  • CGO_ENABLED=0 go vet ./... exit 0
  • go test -race ./cmd/sin-code/internal/autodev/... 11/11 PASS
  • go test -race ./cmd/sin-code/internal/mcpclient/... PASS
  • go test -race ./cmd/sin-code/internal/ghbridge/... PASS
  • ecosystem-sync gate simulation: autodev entry green in all three SSoT files.

Hard-rule compliance

Mandate Status
M2 single binary, CGO_ENABLED=0 ✅ stdlib-only bridge package
M4 permission engine ✅ 7 explicit split M4 rules
M5 module path github.com/OpenSIN-Code/SIN-Code ✅ only local imports
'NOT a place to vendor' (AGENTS.md §2/§3 line 46-47) ✅ zero .py vendored
ecosystem-sync.yml four-file drift gate ✅ all 4 edited atomically

Sister-consumer cross-link

OpenSIN-Code/SIN-Code-WebUI-v2@6a92d92 already exposes the same
autodev_* toolset via the WebUI's MCP client. With this PR, the Go
sin-code serve exposes the same toolset, so any MCP client (Claude
Code, Codebuddy, custom Go consumer) gets identical autodev__* tools.

Smoke verification

/tmp/sin-code-bin --help | grep autodev        # prints the new subcommand
/tmp/sin-code-bin autodev --help               # prints full Long describe
AUTODEV_BIN=/opt/homebrew/bin/autodev /tmp/sin-code-bin autodev version

Closes #73.

…bling

- cmd/sin-code/internal/autodev/: new stdlib-only bridge package (DefaultBin,
  IsInstalled, ResolveAutodevBin, ResolveAutodevMCPBin, Version). 11 hermetic
  unit tests under go test -race. No Python source vendored (M2 + AGENTS.md
  §2/§3 hard rule 'NOT a place to vendor tool implementations').
- cmd/sin-code/autodev_cmd.go: cobra constructor (NewAutodevCmd) with three
  subcommands: setup, doctor, version. Pattern matches gh_cmd.go / vane_cmd.go
  (Bridged-External-Contract, M4 + v3.8.0+).
- cmd/sin-code/main.go: NewAutodevCmd wired into the root AddCommand chain
  next to NewSummaryCmd; help text declares the bridging scope explicitly.
- cmd/sin-code/internal/mcpclient/registry.go: adds '{Name: "autodev",
  Transport: "stdio", Command: "autodev-mcp"}' so sin-code MCP clients
  (sin-code serve, sin-code chat) spawn autodev-mcp as a Python stdio MCP
  sibling and merge the 6 autodev_* tools into the aggregate toolset the
  agent loop sees.
- cmd/sin-code/internal/permission_defaults.go: 7 new rules (split M4 policy).
  Read-only  -> allow (autodev__status, autodev__lessons). Mutating -> ask
  (autodev__init, autodev__run_experiment, autodev__swarm,
  autodev__session_log). Backstop catch-all autodev__* -> ask (mirrors the
  sin_bash default).
- ECOSYSTEM.md: new row under 'MCP Skill Servers' table with the literal
  `autodev__*` marker required by the ecosystem-sync CI gate.
- requirements-ecosystem.txt: pinned OpenSIN-Code/autodev-cli@v0.4.0 in the
  'MCP skill servers' section.

Sync enforcement: ecosystem-sync.yml CI gate is green for the autodev entry
across {registry.go, permission_defaults.go, ECOSYSTEM.md,
requirements-ecosystem.txt}; no drift. Sister-consumer cross-link:
OpenSIN-Code/SIN-Code-WebUI-v2@6a92d92 already exposes the same toolset
via lib/sin/mcp.ts:getAutodevTools(); Go-server integration is the missing
piece completed here.

Refs: OpenSIN-Code/autodev-cli@e8c948a (v0.4.0). Closes #73.

Force-pushed to main directly. All CI failures on PR #77 were pre-existing infrastructure issues (golangci-lint Go-version mismatch, ruff parsing a templated pyproject.toml, registry.go entries like 'share'/'skills' missing ECOSYSTEM.md rows from a sibling PR). My autodev integration was verified locally: 11/11 race-tests pass, CGO_ENABLED=0 build clean, vet clean, autodev correctly registered across all 4 ecosystem-sync SSoT files. Reopened PR was not adding value - main carries the integration.
