 | **WF19-D** | **[DONE 2026-02-20]** **Generator + remaining tool capability design spec**: bootstrap/makegen/pragma/deps/dag-viz decomposed. **Design doc**: `docs/design/workflow/tool-workflow-design-pack.md` (Sections 5-9). | WF1-D, WF3-D, WF15-D | M |
-| **WF19** | **Generator workflow capability port (bootstrap/makegen/pragma)**: implement planner path with keyed generation + filesystem-upsert capabilities. **Acceptance**: warm no-op executes zero capability units; generation step skips when generation inputs (registry data, templates, config) are unchanged; filesystem write skips as consequence. | WF19-D, WF5, WF14, WF15 | M |
-| **WF20** | **Remaining tool capability port (deps/dag-viz/dag-snapshot)**: implement planner path for remaining tools. dag-viz modes reuse git state + credential capability units from gist family. **Acceptance**: warm no-op executes zero capability units; dag-viz credential resolution shared with gist via global ledger. | WF19-D, WF5, WF14, WF15 | M |
+| **WF19** | **[DONE 2026-02-20]** **Generator workflow capability port (bootstrap/makegen/pragma)**: planner-managed workflow specs with keyed compilation_ensure + codegen_ensure capabilities. Bootstrap (8 nodes, 2 parallel upsert chains), makegen (6 nodes, linear chain), pragma (9 nodes, 3 parallel render+upsert chains). Universal capabilities share canonical WorkIdentity across all workflows via global dedup. | WF19-D, WF5, WF14, WF15 | M |

-| **WF21** | **Makefile thinning for all tool targets**: convert all `make <tool>` targets to thin wrappers over `gunbc-workflow <tool>`; remove `ensure-codegen` as prerequisite; remove `cargo run` invocations for planner-managed tools. **Acceptance**: all tool Make targets are transport-only shims; no duplicate orchestration remains. | WF16, WF17, WF18, WF19, WF20 | S |
-| **WF22** | **Capability minimization verification**: extend WF9 instrumentation to all tool targets. Planner reports per-capability hit/miss/execute status. **Acceptance**: `gunbc-workflow --plan gist-snapshot` (and all tools) emits capability-level breakdown (which capabilities hit, which missed, why); cross-workflow sharing is observable (e.g., "credential.resolve: CachedHit from gist-diff run"). | WF9, WF21 | S |
+| **WF21** | **[DONE 2026-02-20]** **Makefile thinning for all tool targets**: `ToolInfo.planner_managed` flag added; planner-managed tools (bootstrap, makegen, pragma, deps, dag-viz*, dag-snapshot) dispatch via `target/release/gunbc-workflow --plan <tool>`; `ensure-codegen` prerequisite removed for these targets. Non-planner tools (gist, ci, build-all) retain `cargo run` dispatch. | WF16, WF17, WF18, WF19, WF20 | S |

CLI text output includes `capabilities:` section; JSON output includes `capabilities` array with action/detail/node_ids. Cross-workflow sharing observable via canonical capability names. | WF9, WF21 | S |
