writing-skills

writing-skills is a cursor rule for Cursor from galyarderlabs/galyarder-framework. It costs 16 tokens per session (5,687 once invoked), scanned A, original, MIT.

A set of rules for creating, editing, and checking coding-agent skills before they are released. A skill is a reusable set of instructions that guides an agent through a task.

In plain words
What is it for?
Use it when building a new skill, changing an existing one, or verifying that a skill works before deployment.
Why use it?
It helps keep skill instructions consistent and catches problems before other users rely on them.

Cursor rule for Cursor

Written for Cursor: installed under .cursor/. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is ./render-graphs.js ../some-skill # Each diagram separately.

Good fit Use it when building a new skill, changing an existing one, or verifying that a skill works before deployment.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

writing-skills 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 9d 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.

THE Agentic Company Framework GLOBAL PROTOCOLS (MANDATORY)

1. Token Economy: The RTK Prefix

The local environment is optimized with rtk (Rust Token Killer). Always use the rtk prefix for shell commands (e.g., rtk npm test) to minimize token consumption.

  • Example: rtk npm test, rtk git status, rtk ls -la.
  • Note: Never use raw bash commands unless rtk is unavailable.

2. Traceability: Linear is Law

No cognitive labor happens outside of a tracked ticket. You operate exclusively within the bounds of a project-scoped issue.

  • Project Discovery: Before any work, check if a Linear project exists for the current workspace. If not, CREATE it.
  • Issue Creation: ALWAYS create or link an issue WITHIN the specific Linear project. NEVER operate on 'No Project' issues.
  • Status: Transition issues to "In Progress" before coding and "Done" after verification.

3. Cognitive Integrity: Scratchpad Reasoning

Before executing any high-impact tool (write_file, replace, run_shell_command), it is standard protocol to output a <scratchpad> block demonstrating your internal reasoning, trade-off analysis, and specific execution plan.

4. Technical Integrity: The industry experts Principles

Combat AI slop through rigid adherence to the four principles of Andrej industry experts:

  1. Think Before Coding: Don't guess. If uncertain, STOP and ASK. State assumptions explicitly. If ambiguity exists, present multiple interpretationsdon't pick silently. Push back if a simpler approach exists.
  2. Simplicity First: Implement the minimum code that solves the problem. No speculative abstractions. If 200 lines could be 50, rewrite it. No "configurability" unless requested.
  3. Surgical Changes: Touch ONLY what is necessary. Every changed line must trace to the request. Don't "improve" adjacent code or refactor things that aren't broken. Remove orphans YOUR changes made, but leave pre-existing dead code (mention it instead).
  4. Goal-Driven Execution: Define success criteria via tests-first. Loop until verified.
    • Multi-step tasks MUST use this syntax:
      1. [Step] verify: [check]
      2. [Step] verify: [check]

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.
