implement

A workflow for implementing one Flutter development task, following project conventions for Riverpod, Freezed, AutoRoute, data models, generated code, and verification.

In plain words
What is it for?
Use it to build a single Flutter feature task and, when run on its own, check that the resulting change works.
Why use it?
It turns a task definition, product requirements, and technical plan into a repository-consistent 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

implement 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.

Flutter Template Task Implementation

You are responsible for implementing one task from a Flutter feature plan while following the repository standards.

Objectives

  1. Read and understand the task definition
  2. Review the PRD and tech spec for context
  3. Apply relevant Flutter skills and repository conventions
  4. Execute the implementation
  5. Verify the change when running standalone, or explicitly skip verification when called by implement-tasks-sequence

File Locations

  • PRD: .claude/tasks/[feature-name]/prd.md
  • Tech Spec: .claude/tasks/[feature-name]/techspec.md
  • Task: .claude/tasks/[feature-name]/[num]_task.md
  • Task list: .claude/tasks/[feature-name]/tasks.md

Applicable Skills

  • feature-screen — when the task adds or changes a screen, route, page split, UI state, or navigation.
  • feature-data-flow — when the task adds backend/storage data flow, DTOs, entities, use cases, or state that loads real data.
  • widget-test — when the task changes shared UI, provider-driven visual states, or user-visible behavior that can be covered by a focused widget test.
  • layout-debug — when the task involves overflow fixes, responsive behavior, scroll/constraint issues, or text clipping.
  • lint-format — when running standalone and the change does not need the broader build-verify suite.
  • build-verify — when running standalone and the task changed behavior, generated-code inputs, routes, platform setup, dependencies, tests, or other shared behavior.
  • pr-review — optional standalone final check when the user asks for a review after implementation.

Do not use KMP, Swift, iOS coordinator, Gradle, Spotless, Detekt, Tuist, or native iOS test-runner skills in this Flutter workflow.

Invocation Modes

Standalone mode

Use when the user directly asks to implement one task. Complete implementation and run the appropriate verification commands before reporting done.

Sequence mode

Use when called by implement-tasks-sequence. In this mode:

  • read the same task, PRD, and tech spec
  • write only the source changes for the assigned task
  • do not run builds, tests, lint-format, build-verify, or pr-review
  • do not commit or stage
  • report what changed and return control to the orchestrator

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.

implement is a skill published in the GitHub repository strvcom/flutter-template (24 stars, last pushed 2mo ago), licensed MIT. It adds 105 tokens to every session and 1,637 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 2026-08-30.
