single_child_two_dimensional_scroll_view CLAUDE.md is an instructions file for Claude Code from sjhorn/single_child_two_dimensional_scroll_view. It costs 834 tokens per session, scanned A, original, BSD-3-Clause.

A set of Claude Code instructions for a Flutter and Dart project. It defines required issue tracking, test-driven development (TDD), quality checks, documentation, commit rules, and coding boundaries.

In plain words
What is it for?
Use it to guide issue-based development, write tests before implementation, run the project’s CI wrappers, document public code, and keep domain code separate from Flutter code.
Why use it?
It gives the coding agent fixed project rules, reducing inconsistent workflows and missed checks.

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

single_child_two_dimensional_scroll_view CLAUDE.md 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 yesterday.

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.

Rules

  • All work starts from a GitHub issue. No issue → create one before writing code.
  • TDD is mandatory. Failing test → implement → refactor → commit.
  • qa agent gates every commit. Never run flutter test, flutter analyze, dart format directly — always scripts/ci/ wrappers.
  • Every public symbol has /// dartdoc. Zero dart doc warnings.
  • 90% test coverage for all code
  • Commit format: type(scope): description — one ROADMAP checkbox per commit max.
  • No raw shell in Bash tool calls. In Bash tool calls, never use $(), sed, |, >, &&, ||, tr, 2>&1. Never prefix commands with bash — run scripts directly (e.g. scripts/ci/ci_gate.sh, not bash scripts/ci/ci_gate.sh). The scripts/ci/ wrappers handle shell complexity internally. For ad-hoc commands, use scripts/ci/capture.sh <label> <command> [args...].
  • After any user correction → update tasks/lessons.md.
  • Domain layer (lib/src/domain/) is pure Dart — no Flutter imports.
  • No dynamic types.
  • No business logic in widgets.

Cross-layer order: domain → infrastructure → presentation → qa → docs → commit


Workflow

  1. Issueuse the github agent to start <number> (or create if none exists)
  2. Reduse the <owning> agent to write a failing test for <task>use the qa agent to confirm it fails
  3. Greenuse the <owning> agent to implement minimum to passuse the qa agent to confirm it passes
  4. Refactoruse the <owning> agent to refactoruse the qa agent to confirm still green
  5. Gateuse the qa agent to run the full gate
  6. Committype(scope): description
  7. Repeat steps 2–6 for each behaviour in the issue
  8. PRuse the github agent to pr <number> → tick ROADMAP checkbox
  9. Stop — Do not start the next issue until the PR is submitted

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.
