+  - phase: 20-03
+    provides: ApprovalStore, ReAct loop approval gate, ApprovalRequest/ApprovalStatus types

+  - agentix deny <id> CLI command — deny pending requests with optional reason
+  - agentix approvals CLI command — list pending/all approval requests with color-coded table
+  - quickstart/semi-autonomous-agent/ — complete infra-guardian example demonstrating semi-autonomous mode
+  - docs/concepts/approval-workflows.md — finalized with quickstart reference and REST API section

+# Phase 20 Plan 05: CLI approve/deny/approvals + quickstart + docs + CHANGELOG v2.0.0-alpha.8
+
+**`agentix approve/deny/approvals` CLI commands, infra-guardian quickstart example, and complete approval workflow documentation with CHANGELOG v2.0.0-alpha.8**
+
+## Performance
+
+- **Duration:** 20 min
+- **Started:** 2026-03-23T05:35:00Z
+- **Completed:** 2026-03-23T05:55:00Z
+- **Tasks:** 5 (1-2 already done in prior wave, 3-5 executed this session)
+- **Files modified:** 8
+
+## Accomplishments
+
+- CLI commands (`agentix approve`, `agentix deny`, `agentix approvals`) fully implemented in `commands/approvals.rs` with color-coded table output and JSON output support
+- `quickstart/semi-autonomous-agent/` created with `agent.yaml` (infra-guardian, kubectl/aws/shell flagged tools) and `SOUL.md`
+- `docs/concepts/approval-workflows.md` updated with Quickstart Example section referencing the new quickstart
+- `docs/reference/cli-approvals.md` created with full command reference (already existed from prior work)
+- CHANGELOG `v2.0.0-alpha.8` entry documents complete Phase 20 feature set
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add approve and deny CLI commands** — already completed in prior phase (commands present in cli.rs, main.rs, commands/approvals.rs, client.rs)
+2. **Task 2: Add approvals list CLI command** — already completed in prior phase (list function in approvals.rs)
+3. **Task 3: Create quickstart semi-autonomous agent example** — `a25f30e` (feat)
+4. **Task 4: Update docs and CHANGELOG** — `b809cb0` (docs) — quickstart reference added; CLI ref and CHANGELOG already existed
+5. **Task 5: Final verification** — no code changes, verified via cargo check + test run
+
+## Files Created/Modified
+
+- `/quickstart/semi-autonomous-agent/agent.yaml` — infra-guardian with semi-autonomous mode, kubectl/aws/shell flagged tools
+- `/quickstart/semi-autonomous-agent/SOUL.md` — agent identity with safety-first policy for destructive operations
+- `/docs/concepts/approval-workflows.md` — added Quickstart Example section with step-by-step instructions
+- `/docs/reference/cli-approvals.md` — full CLI reference for approve/deny/approvals commands (already existed)
+- `/crates/agentix/src/commands/approvals.rs` — list/approve/deny handlers (already existed from prior work)
+- `/CHANGELOG.md` — v2.0.0-alpha.8 entry (already existed from prior work)
+
+## Decisions Made
+
+- All three approval commands consolidated in `commands/approvals.rs` (not separate `approve.rs` as the plan suggested) for simpler code organization
+- Quickstart agent named `infra-guardian` as a realistic k8s infrastructure management scenario
+- Docs organized as per-command reference files (`cli-approvals.md`) rather than a single `cli.md` — consistent with Phase 21 pattern (`cli-channels.md`)
+
+## Deviations from Plan
+
+None - Tasks 1, 2, and the CHANGELOG/CLI reference were already complete from prior phase waves. Task 3 (quickstart) and Task 4 (approval-workflows.md update) were executed this session. The plan's reference to `commands/approve.rs` was implemented as `commands/approvals.rs` — a structural improvement that keeps all approval commands together.
+
+## Issues Encountered
+
+None. All tests pass (115 agentix-core, 31 agentix-runtime). Workspace compiles clean with only pre-existing warnings.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- Phase 20 (Approval Workflows) is fully complete — all 5 plans done
+- All approval CLI commands are functional and tested
+- Documentation, quickstart, and CHANGELOG are current
+- Ready to advance to Phase 20 completion and STATE.md update
