prompt-pack

prompt-pack is a skill for Claude Code from pe-menezes/vibeflow-claude. It costs 63 tokens per session (1,173 once invoked), scanned A, a copy of prompt-pack, MIT.

A tool that builds a self-contained instruction package from a specification and real code patterns in the project. It helps another coding agent work with the project's existing conventions without reading the whole repository first.

In plain words
What is it for?
Use it to prepare implementation instructions for agents such as Claude Code, Cursor, or Copilot, based on the project's own code patterns.
Why use it?
It reduces the context and setup needed when handing implementation to another session or coding agent.

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

prompt-pack 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Description and examples

What it does: Reads a spec from .vibeflow/specs/ (or path), builds a single prompt that includes objective, DoD, anti-scope, and real code patterns. Saves to .vibeflow/prompt-packs/<slug>.md. Give that file to the coding agent so it implements without needing the rest of the repo context.

Examples:

  • prompt-pack .vibeflow/specs/login-flow.md — Generate prompt pack from the login-flow spec.
  • prompt-pack login-flow — Same; agent finds the spec by name.

Language

Write the whole pack — opening line, objective, DoD, anti-scope, guidance — in the user's detected language. Code, paths, and technical names stay in English.

Generate a self-contained prompt pack for the spec in the user's current request.

Steps

  1. Validate spec size. Read the spec: more than 7 DoD checks, or over the budget (the spec's Budget field, else the Suggested budget line in .vibeflow/index.md, else ≤6 files), and you stop without generating the pack — tell the user it exceeds limits (N checks / N files) and to run gen-spec again to split it first.
  2. Locate the spec: a file path is read directly; a feature description is matched against .vibeflow/specs/. No spec exists → generate one in the gen-spec format, save it, then continue.
  3. Read .vibeflow/conventions.md, plus the pattern docs the spec lists under Applicable Patterns. If it lists none, resolve them: read the ## Pattern Registry block in index.md (between <!-- vibeflow:patterns:start/end --> markers) and cross-reference its tags and modules against the spec's scope — top 3–5 matches; with no registry, infer which are relevant.
  4. Read the codebase files this task touches, plus anything the spec lists under References.
  5. Generate the pack.

The pack opens with

You are only seeing this prompt; there is no context outside it.

Then, in this order

1. Objective and Definition of Done

From the spec. Non-negotiable.

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.
