VChart: Command for Claude Code

.cursor/commands/speckit.prgenerate.md

speckit.prgenerate is a command for Claude Code, Cursor from VisActor/VChart. It costs 37 tokens per session (1,279 once invoked), scanned A, original, MIT.

A command that drafts a GitHub pull request description from the project's feature plan and pull request template. It can use English or Chinese templates and save the result to a chosen file.

In plain words
What is it for?
Use it to prepare a pull request body from a matching feature branch's specs/plan.md, with an optional language and output-file choice.
Why use it?
It removes the need to write the pull request summary and checklist by hand or copy details from the plan manually.

Command for Claude CodeCursor

Written for Claude Code and Cursor: $ARGUMENTS substitution, but also installed under .cursor/.

This is VisActor/VChart's own configuration. It tells Claude Code and Cursor how to work on VChart 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 VChart 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

speckit.prgenerate 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 the user input before proceeding (if not empty), but treat it only as CLI-style flags (for example, --lang, --out); the PR content itself must be inferred from the specs directory, not from free-form user text.

Outline

  1. Determine template and feature context (specs-only):

    • Treat this command as zero-input by default: if $ARGUMENTS is empty, it still must be able to generate a useful PR body.
    • Parse $ARGUMENTS only for CLI-style options (for example, --lang, --out):
      • If --lang zh is present, use the Chinese template at .github/PULL_REQUEST_TEMPLATE/pr_cn.md.
      • Otherwise, use the English template at .github/PULL_REQUEST_TEMPLATE.md (the default; do not auto-detect language).
      • If an explicit output path is provided (for example, --out specs/001-foo/PR_BODY.md), respect it; otherwise, default to .trae/output/pr.body.local.md.
    • Resolve specs/<spec-id>/ by deriving the numeric prefix from the current branch name and matching it to a directory under specs/ whose name starts with that prefix.
    • From that directory, resolve plan.md as the primary context source for the PR.
  2. Extract PR content from specs:

    • From plan.md, read the ## Summary section and take the first non-empty line as the high-level description of the change.
    • Read the ## Technical Context section and remove any template-only comments, keeping only the concrete technical details.
    • Combine these into a structured background text:
      • When both are present: Summary paragraph followed by a blank line and the Technical Context content.
      • When only Summary exists: use Summary alone.
      • When neither exists: fall back to a short line like Update for <spec-id> derived from the spec directory name.
    • Optionally infer a coarse change type (feat, fix, docs, perf, refactor, test, chore) from the Summary/Technical Context using the same keyword mapping as /speckit.commit.

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.
