What is speckit.skilltypesync?

A command that keeps skill reference files in sync with changes to VChart’s public settings and type definitions. VChart is a charting library, and these files describe the types and options its users can configure.

Checking changed files, finding affected TypeScript types, and updating matching type metadata and detail references after feature development.

It prevents documentation-like skill resources from becoming outdated after an API or configuration change. It also skips unnecessary work when the changes do not affect user-facing types.

How VisActor/VChart configures Claude Code and Cursor

About the project

VChart is a cross-platform charting library for building data visualizations and annotated, animated storytelling charts. Developers use it across desktop, mobile web, and several mini-program environments through its core and framework-specific packages. The catalogue entries support work with this charting project.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00029	$0.00873
Opus 5.5	$0.00012	$0.00349
Sonnet 5.5	$0.00006	$0.00175
Haiku 4.5	$0.00003	$0.00087

Security

Grade A, and why

speckit.skilltypesync 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.

User Input

$ARGUMENTS

You MUST consider user input if provided. Treat it as optional CLI-style overrides only (for example: --base develop, --force, --types ILabelSpec,IData).

Outline

Resolve diff scope:
- Default base branch is develop.
- If $ARGUMENTS contains --base <branch>, use that branch as comparison base.
- Collect changed files from:
  - staged + unstaged local changes, and
  - branch diff against base (<base>...HEAD).
- De-duplicate all changed paths.
Determine whether sync is required:
- Mark as requires sync when changes affect user-facing configuration or API/type definitions, including (but not limited to):
  - packages/vchart/src/typings/**
  - packages/vchart/src/chart/**/interface/**
  - packages/vchart/src/component/**/interface/**
  - packages/vchart/src/series/**/interface/**
  - packages/vchart/src/theme/**
  - any public API or option schema files referenced by VChart docs.
- If no matching files and no --force, stop with a clear summary: "No user config/API changes detected, skill type sync skipped."
Identify impacted type entities:
- From changed TypeScript definitions, extract impacted type/interface names (for example ILabelSpec, IData, ITheme).
- Build two impact sets:
  - Meta impact: chart/common entries that need type-meta/*.json updates.
  - Detail impact: concrete types needing type-details/*-Type-Definition.md updates.
- If $ARGUMENTS includes --types, merge explicit type names into the detail impact set.
Update type-meta resources:
- Target directory: skills/vchart-development-assistant/references/type-meta/.
- For each impacted chart/common meta file:
  - sync user-visible property paths,
  - sync required flags,
  - sync type and isSimple fields,
  - remove stale keys that no longer exist in source typings.
- Keep JSON valid and stable (no duplicated keys, deterministic field ordering where possible).

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.
