DynamoHome: Skill for Claude Code

.claude/skills/bugfix/SKILL.md

bugfix is a skill for Claude Code from DynamoDS/DynamoHome. It costs 0 tokens per session (620 once invoked), scanned A, original, MIT.

A step-by-step method for reproducing, investigating, and fixing bugs in the DynamoHome application, including problems specific to its embedded browser view.

In plain words
What is it for?
Use it when data is missing, localization is broken, settings do not persist, the app crashes outside Dynamo, the wrong view appears, or an action does nothing.
Why use it?
It narrows common failures to their likely causes and requires checking the existing behavior before code is changed.

This is DynamoDS/DynamoHome's own configuration. It tells Claude Code how to work on DynamoHome itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything DynamoHome configures →

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

bugfix 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 2mo 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.

Bug Fix Workflow – DynamoHome

Use this workflow when diagnosing and fixing a bug.

Steps

1. Reproduce the issue

Before touching any code:

  • Identify the affected module: Recent, Samples, Learning, Sidebar, or layout
  • Check whether the bug occurs in dev mode (npm run start) or only inside Dynamo (WebView context)
  • Dev-mode bugs: reproduce with mock data from src/assets/
  • WebView-only bugs: root cause is likely in src/functions/utility.ts or a missing window.chrome?.webview guard

2. Locate the root cause

Common bug locations in DynamoHome:

Symptom Where to look
Data not displaying receiveXxxDataFromDotNet callback and JSON parsing in the page component
Localization broken / missing text Key missing in one or more of the 14 locale files
Settings not persisting saveHomePageSettings() in utility.ts and SettingsContext.tsx
Crash on load / outside Dynamo Missing window.chrome?.webview optional chaining guard
Wrong view mode shown SettingsContext values (recentPageViewMode, samplesViewMode)
Action does nothing in Dynamo Missing await on scriptObject.* calls — all hostObjects methods are async

3. Apply the fix

  • Make the smallest change that fixes the issue — do not refactor adjacent code
  • Do not change unrelated files
  • If the fix touches window globals or the settings JSON schema:
    • Global callback names must not change
    • Settings field names must not change (adding new fields is safe)

4. Add a regression test

For every bug fixed, add or update a test that would have caught it:

// tests/unit/ComponentName.test.tsx
it('does not crash when graphData is empty', () => {
  render(<PageRecent graphs={[]} />);
  expect(screen.getByText(/no recent files/i)).toBeInTheDocument();
});

Run: npm run test:unit

5. Verify everything passes

npm run lint:check    # No new lint errors
npm run test:unit     # All unit tests pass (including new regression test)
npm run build         # Dev bundle still builds

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.

bugfix is a skill published in the GitHub repository DynamoDS/DynamoHome (3 stars, last pushed 11d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 620 tokens. 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.
