Create an Implementation Plan

kdlbs/plan

Source kdlbs/kandev ↗License AGPL-3.0

Create a committed implementation plan from a feature spec. Explores the codebase, designs the approach, and produces docs/plans/<feature>/plan.md plus individual task files. Use after writing a spec and before implementing.

Tokens, turns and time describe resource use, not a dollar price.

This benchmark measured an earlier version of the skill.

A newer attempt on gemini-3.6-flash on 10/2/2026 did not produce a publishable comparison (not comparable). The snapshot above is the previously measured run.

Prompt

While analyzing requirements REQ-STORAGE-002 and system design docs for docs/plans/cloud-storage/, we noticed that the existing storage service code directly contradicts the system design contract. Should we proceed with decomposing task work orders or pause?

SKILL.md280 linessingle file

Create an Implementation Plan

Translate requirements and system designs into a delivery plan under docs/plans/<initiative>/. The plan and its work-order files are implementation records. They are not product specifications.

Read docs/specs/guide/plans-and-work-orders.md and docs/specs/guide/traceability-and-lifecycle.md before you write the plan.

Inputs

Read these sources in full:

The applicable requirement documents and REQ-* or AC-* IDs.
The applicable system-design documents.
Related ADRs.
The relevant source, tests, and one similar implementation.

Use the legacy feature specification during migration only when no replacement requirement or design exists.

Read each spec's Implementation Plans and related-plan links, then inventory all existing companion plan directories. Treat linked packages as one synchronized implementation record: reconcile every affected task scope, E2E scenario matrix, status, and exact final verification results/counts before completion.

Outputs

Create:

docs/plans/<initiative>/plan.md
docs/plans/<initiative>/task-<NN>-<short-slug>.md

plan.md is the work-package manifest. Each task-*.md file is one work order.
