vibeusage CLAUDE.md

vibeusage CLAUDE.md is an instructions file for coding agents from victorGPT/vibeusage. It costs 497 tokens per session, scanned A, original, MIT.

A project guidance file for Claude Code, an AI assistant that helps edit software. It describes when to use OpenSpec, a workflow for proposing and tracking significant changes.

In plain words
What is it for?
Use it to check project conventions, list active specifications, create change proposals, validate them, and archive completed proposals.
Why use it?
It helps the assistant follow the project's existing development process instead of making major changes without a written proposal. It also distinguishes feature work from smaller fixes.

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

vibeusage 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 3d 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.

Project Guidelines for Claude Code

OpenSpec Workflow

This project uses OpenSpec for spec-driven development. Before making significant changes:

  1. Read openspec/project.md for project conventions
  2. Check openspec/AGENTS.md for the full OpenSpec workflow
  3. Run openspec list to see active changes
  4. Run openspec list --specs to see existing specifications

When to Create a Proposal

Create a proposal (openspec/changes/<id>/) for:

  • New features or capabilities
  • Breaking changes (API, schema)
  • Architecture or pattern changes
  • Security-related changes

Skip proposals for:

  • Bug fixes (restore intended behavior)
  • Typos, formatting, comments
  • Dependency updates (non-breaking)

OpenSpec Commands

openspec list                     # List active changes
openspec list --specs             # List specifications
openspec show <item>              # View change or spec details
openspec validate <id> --strict   # Validate a change proposal
openspec archive <id> --yes       # Archive after deployment

Proposal Structure

openspec/changes/<change-id>/
├── proposal.md     # Why and what
├── tasks.md        # Implementation checklist
├── design.md       # Technical decisions (optional)
└── specs/
    └── <capability>/
        └── spec.md # ADDED/MODIFIED/REMOVED requirements

Project Structure

  • bin/ - CLI entry points
  • dashboard/ - React dashboard (Vite)
  • insforge-src/ - Backend Edge Functions source
  • insforge-functions/ - Built backend functions (generated)
  • openspec/ - Specifications and change proposals

Key Commands

npm test                          # Run tests
npm run build:insforge            # Build backend functions
npm run dashboard:dev             # Start dashboard dev server
npm run validate:copy             # Validate copy registry

Conventions

  • Platform: macOS-first
  • All user-facing text managed in dashboard/src/content/copy.csv
  • Token data only - never store or upload conversation content
  • Use UTC for all timestamps
  • Half-hour buckets for aggregation

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.
