+# PR: feat/cli-full-command-tree → molecule-cli
+
+## Status
+- Branch: `feat/cli-full-command-tree` (pushed locally, GH_TOKEN dead — cannot push to origin)
+- Existing PR #3 (`feat/cli-workspace-commands`) is superseded by this branch
+- When token recovers: push branch, close #3, open this PR
+
+## PR Title
+feat(cli): implement full CLI command tree
+
+## PR Body
+
+## Summary
+Implements the full CLI command tree for molecule-cli, the primary
+user-facing tool for the Molecule AI platform.
+
+- `cmd/molecule/main.go`: entry point calling `cmd.Execute()`
+- `internal/cmd/root.go`: cobra root with global flags (`--api-url`,
+  `--verbose`, `--output`, `--config`), registers all 4 command groups
+- `internal/cmd/workspace.go`: 7 subcommands (list, create, inspect,
+  delete, restart, audit, delegate)
+- `internal/cmd/agent.go`: 4 subcommands (list, inspect, send, peers)
+- `internal/cmd/platform.go`: 2 subcommands (audit, health)
+- `internal/cmd/config.go`: 5 subcommands (list, get, set, init, view)
+- `internal/cmd/http.go`: `runHTTP` helper shared by agent send and
+  workspace delegate
+- `internal/client/platform.go`: control plane HTTP client with
+  workspace/agent/health/audit operations
+
+All 18 subcommands wire to the platform API via `MOLECULE_API_URL`.
+Binary builds cleanly to `./bin/mol` with Go 1.23.
+
+Resolves: KI-001 (entry point), KI-002 (partial — API client), KI-003 (go.sum).
+
+## Test plan
+- [ ] `go build -o bin/mol ./cmd/molecule` — BUILD OK
+- [ ] `bin/mol --help` — shows all 4 command groups
+- [ ] `bin/mol workspace --help` — shows all 7 workspace subcommands
+- [ ] `bin/mol agent --help` — shows all 4 agent subcommands
+- [ ] `bin/mol config --help` — shows all 5 config subcommands
+- [ ] `bin/mol platform --help` — shows audit, health
+- [ ] `bin/mol --version` — shows version
+- [ ] `MOLECULE_API_URL=http://localhost:8080 bin/mol workspace list` — hits API
+- [ ] `bin/mol workspace list --output json` — structured output works
+- [ ] Run CI (go test ./..., go build)
