At a glance

SoftSpark working agreement: never guess a home directory path, give at least three alternatives, and apply a devil's advocate critique to decisions.

  • Development work in your project
  • SKILL.md covers Skill Tiers, Path Safety and User Preferences
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Claude Toolkit Rules is an agent skill from softspark/ai-toolkit. SoftSpark working agreement: never guess a home directory path, give at least three alternatives, and apply a devil's advocate critique to decisions. Triggers: toolkit, conventions, workflow, alternatives, review.

Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. The repository describes itself as: Professional-grade AI coding toolkit: 94 skills, 44 agents, multi-platform (Claude, Cursor, Windsurf, Copilot, Gemini, Cline, Roo Code, Aider, Augment, Antigravity, Codex CLI… The licence is Apache-2.0.

When your agent uses it

  • Development work in your project

Example prompts

  • “/claude-toolkit-rules”

Requirements

  • Pre-approved tools (allowed-tools): Read

What it can do on your machine

Read from SKILL.md and the folder at commit d64db2b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Claude Toolkit Rules loads about 503 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 188 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~59
When it runs · the whole SKILL.md, loaded when a task matches
~503

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Claude Toolkit Rules

This rule comes from app/rules/claude-toolkit-rules.md in ai-toolkit. It applies to every task in this workspace, not only when it is loaded.

Claude Toolkit

Shared AI development toolkit — lifecycle hooks, safety constitution, multi-platform support.

Skill Tiers

  • Tier 1 — single-agent: /debug, /review, /refactor, /analyze, /docs, /plan, /explain, /tdd, /triage-issue
  • Tier 1.5 — planning: /write-a-prd → /prd-to-plan → /prd-to-issues; design: /design-an-interface, /architecture-audit, /refactor-plan
  • Tier 2 — multi-agent: /workflow <type> (feature-development, backend-feature, frontend-feature, api-design, database-evolution, test-coverage, security-audit, debugging, incident-response, spike, codebase-onboarding, performance-optimization, infrastructure-change, application-deploy, proactive-troubleshooting)
  • Tier 3 — custom: /orchestrate <desc> (3–6 agents) | /swarm <mode> <desc> (map-reduce | consensus | relay)

Path Safety

  • NEVER guess or hallucinate user home directory paths
  • Use ~ or $HOME instead of a hardcoded /Users or /home prefix followed by a user name. The literal prefix is deliberately not written out here: the plugin export scans shipped files for exactly that pattern, so an example of the mistake would be indistinguishable from the mistake.
  • When an absolute path is needed, run echo $HOME first to get the correct value

User Preferences

  • Style: Direct & efficient. No pleasantries. Measurable results.
  • Methodology: Provide >=3 alternatives. Use Socratic questioning.
  • Review: Apply "Devil's Advocate" critique to decisions.
