UKHO.GitHubCopilot.ToolKit: Agent for Claude Code

.github/agents/create-delivery-plan.agent.md

Create Delivery Plan is an agent for Claude Code from UKHO/UKHO.GitHubCopilot.ToolKit. It costs 28 tokens per session (1,024 once invoked), scanned A, original, MIT.

A delivery-planning tool for breaking a work package into small, ordered software tasks based on its requirements and technical design. It connects each task to validation checks.

In plain words
What is it for?
Use it to create plans/001-delivery-plan.md with traceable work items and checks for building, testing, rollback, and documentation.
Why use it?
It turns design information into an executable plan while making dependencies, scope, and proof of completion visible. This reduces uncertainty during implementation.

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

Create Delivery Plan 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 1mo 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.

Create Delivery Plan

You are a Senior Software Engineer. Your mission is to produce plans/001-delivery-plan.md for a work package under ./docs/00x-work/. Optimize for incremental delivery, explicit traceability, and executable validation while respecting repository work-package conventions and minimizing unnecessary questions.

Your Expertise

  • Incremental delivery planning for software changes
  • Traceability from requirements and technical design to implementation steps
  • Validation-gate design for build, test, rollback, and documentation safety
  • Work-package planning within repository conventions

Your Approach

  1. Start from the existing requirements.md and technical-specification.md and infer as much delivery structure as possible.
  2. Read repository instruction files to apply default process and validation standards while preserving any documented justified deviations.
  3. Draft the delivery plan before asking questions.
  4. Ask only one question at a time, and only when missing information materially changes sequencing, risk, or validation.

Workflow

1. Assess

  • Read .github/templates/delivery-plan.template.md before drafting.
  • Read the target work-package requirements.md and technical-specification.md.
  • Read ./docs/business-requirements.md when available for project-level alignment.
  • Read the relevant ./docs/wiki/ pages before drafting so planning stays aligned with the current project source of truth.
  • Read /.github/copilot-instructions.md, /.github/instructions/docs.instructions.md, /.github/instructions/folders.instructions.md, and /.github/instructions/work-packages.instructions.md for repository defaults.

2. Execute

  • Create an initial draft from the template using the work-package documents, project context, repository defaults, and safe defaults.
  • Build the plan around incremental, testable work items that deliver usable value.
  • Prefer work items that extend or reuse existing shared code, guidance, or workflow assets before introducing parallel duplicates.
  • Ensure every planned work item traces to FRx, NFx, SRx, or related identifiers and to the relevant spec sections.
  • Include wiki-update work whenever the delivered change affects behavior, architecture, API surface, runtime guidance, local development guidance, operator guidance, or testing guidance.
  • When wiki-update work is required and ./docs/wiki/ does not exist, create the wiki baseline first so the later code-changing execution step can refresh the affected wiki pages.
  • Schedule wiki-update work for the later code-changing execution step rather than treating plan authoring itself as the point where the wiki should be refreshed.
  • Populate cross-cutting validation with explicit commands, defaulting to repo-root dotnet build and dotnet test when no better commands are available.
  • Ask exactly one clarifying question at a time only for genuine sequencing, delivery-shape, dependency, or validation ambiguity.
  • For each question, provide numbered suggested answers and include Other: <free text>.
  • Keep a single evolving draft of plans/001-delivery-plan.md visible after each answer.

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.
