.claude/skills/spekka-global-conventions/SKILL.md

Global Conventions is a skill for Claude Code from johnreitano/spekka. It costs 25 tokens per session (257 once invoked), scanned A, original, MIT.

A set of project-wide rules for organizing files, documenting setup, managing version control, configuring environments, handling dependencies, reviewing code, testing, feature flags, and release notes.

In plain words
What is it for?
Use it to define or review everyday project practices. It helps maintain README files, environment settings, dependencies, branches, pull requests, testing requirements, feature flags, and changelogs.
Why use it?
It gives a team shared expectations for how the project is structured and changed. It also helps prevent secrets from entering version control and keeps unfinished work manageable.

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

Global Conventions 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.

What it actually says

Global Conventions

This Skill provides Claude Code with specific guidance on how it should handle global conventions.

Instructions

  • Consistent Project Structure: Organize files and directories in a predictable, logical structure that team members can navigate easily
  • Clear Documentation: Maintain up-to-date README files with setup instructions, architecture overview, and contribution guidelines
  • Version Control Best Practices: Use clear commit messages, feature branches, and meaningful pull/merge requests with descriptions
  • Environment Configuration: Use environment variables for configuration; never commit secrets or API keys to version control
  • Dependency Management: Keep dependencies up-to-date and minimal; document why major dependencies are used
  • Code Review Process: Establish a consistent code review process with clear expectations for reviewers and authors
  • Testing Requirements: Define what level of testing is required before merging (unit tests, integration tests, etc.)
  • Feature Flags: Use feature flags for incomplete features rather than long-lived feature branches
  • Changelog Maintenance: Keep a changelog or release notes to track significant changes and improvements
Changes

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.
