skilllite: Instructions file for Claude Code

CLAUDE.md

skilllite CLAUDE.md is an instructions file for Claude Code from EXboys/skilllite. It costs 681 tokens per session, scanned A, original, MIT.

Project instructions for Claude that point to the files defining the project's rules, architecture, security, testing, documentation, and task process.

In plain words
What is it for?
Use them when contributing to the project, deciding which specifications apply, creating tasks, and following the required validation and documentation workflow.
Why use it?
They give Claude a shared source of truth so important rules do not need to be copied into one instruction file or remembered informally.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is EXboys/skilllite's own configuration. It tells Claude Code how to work on skilllite 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 skilllite 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

skilllite 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 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.

Claude Project Instructions

Use the same rule semantics as Cursor, but follow Claude's file conventions.

Source of Truth

  • Verification integrity (highest priority): spec/verification-integrity.md
  • Task artifact language policy: spec/task-artifact-language.md
  • Spec routing and enforcement: spec/README.md
  • Architecture constraints: spec/architecture-boundaries.md
  • Rust coding conventions: spec/rust-conventions.md
  • Security constraints: spec/security-nonnegotiables.md
  • Testing policy: spec/testing-policy.md
  • Docs sync policy: spec/docs-sync.md
  • Structured-signal-first policy: spec/structured-signal-first.md
  • Task workflow: tasks/README.md
  • Task board: tasks/board.md

Do not duplicate rule content in this file. Follow the referenced files directly.

Contribution Modes

  • External/community contribution (lightweight):
    • Task ID: N/A is acceptable for small fixes/docs/issues.
    • Creating tasks/TASK-.../ is optional.
    • Validation evidence and regression notes are still required in PR.
  • Core/maintainer contribution (strict):
    • Use full tasks/TASK-.../ lifecycle for non-trivial work.

Required Workflow

  1. Determine task type and inject specs using spec/README.md.
  2. For non-trivial work, create/reuse a task folder in tasks/TASK-.../.
  3. Before implementation starts, ensure baseline task artifacts are ready:
    • TASK.md scoped with acceptance criteria
    • PRD.md drafted (or explicitly N/A with reason)
    • CONTEXT.md drafted (or explicitly N/A with reason)
  4. Keep task artifacts updated:
    • TASK.md
    • PRD.md
    • CONTEXT.md
    • STATUS.md
    • REVIEW.md
    • Keep task artifacts in English per spec/task-artifact-language.md
  5. Keep tasks/board.md in sync with real status.
  6. For any Rust code change, enforce spec/rust-conventions.md and spec/testing-policy.md.
  7. For behavior/command/env/doc/release changes, enforce spec/docs-sync.md.

Task Creation

Prefer the standard task bootstrap script:

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.
