ba-post-implementation

A post-implementation review workflow for checking a user-interface task after a developer says it is ready for deployment. It compares the implementation changes with the approved design handoff and the task's definition of done.

In plain words
What is it for?
Use it to review the code changes and, when available, the deployed result, then produce a completeness verdict for a UI-bearing task.
Why use it?
It provides an independent check that the built interface matches what was agreed before deployment. This reduces reliance on the developer's own claim that the work is complete.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ba-post-implementation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

BA Phase 5 — Post-Implementation Completeness Verification

When to use

You are the BA, dispatched in post-implementation mode after FE Dev proposed ready-for-deploy for a UI-bearing task. Independently verify the implementation matches the design-confirmed handoff and the task DoD (you are a fresh reviewer, never a rubber-stamp), and emit the verdict report. Mirrors Phase 3 but operates on the implementation diff.

Phase 5 — Post-Implementation Completeness Verification (UI tasks)

This phase runs after FE Dev proposes to_status: ready-for-deploy for any UI-bearing task (track: fe / be+fe, or Design sub-status: set in master plan, or Linked Surface: non-null). The Orchestrator dispatches BA in post-implementation mode (subagent_type: ba + dispatch parameter mode: post-implementation) BEFORE committing the master-plan transition.

This phase mirrors Phase 3 (design completeness against the handoff) but operates against the implementation diff. Phase 3 asks "is the design complete?"; Phase 5 asks "is the implementation complete?" Without Phase 5, the kit gates design existence rigorously but trusts implementation to self-attest — the 2026-06-04 FR-022 batch-UI silent-drop incident is what that asymmetry costs.

Trigger
  • FE Dev has emitted plan-update.json proposing to_status: ready-for-deploy for a UI-bearing task.
  • The ui-task-readiness-guard.cjs hook has already accepted the write (the artifact set — docs/uiux/handoffs/<task-id>.md, docs/uiux/refs/<task-id>.md, docs/uiux/visual-specs/<task-id>.md, docs/test-cases/by-task/<task-id>/ — is present and content-complete on disk). If the hook refused, the Orchestrator routes the gap to UI/UX Designer / QA-Author / FE Dev re-dispatch first; this phase does NOT run while the artifact set is incomplete.
  • The Orchestrator dispatches you with: task_id, the FE Dev worktree path (.worktrees/fe-dev-<task-id>/), and a copy of the FE Dev plan-update.json (notes + DoD-scope justifications).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ba-post-implementation is a skill published in the GitHub repository evolplus/talos (8 stars, last pushed 28d ago), licensed Apache-2.0. It adds 93 tokens to every session and 2,245 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
