spk-start-hereStart here for Spec Kitty. An agent skill from spec-kitty/spec-kitty.
Spk Start Here is an agent skill from spec-kitty/spec-kitty. Start here for Spec Kitty. Orient CLI users and supported agent-harness users; choose the right command, skill family, and recovery path.
Its SKILL.md is about 550 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 Agent Workflows. The repository describes itself as: Spec-Driven Development with organizational governance. Specs tell AI agents what to build; Charter governs how they build it. Git-native missions, enforceable workflows, and… The licence is MIT.
3 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 4cabb90. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Spk Start Here loads about 550 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 269 words of instructions outside code blocks.
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.
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.

Spk Start Here fits situations like: agent Workflows work in your project.
Run `npx skills add spec-kitty/spec-kitty --skill spk-start-here -a claude-code`. Or copy the skill folder (src/charter/offering/skills/spk-start-here in spec-kitty/spec-kitty) into .claude/skills/spk-start-here in your project. Claude Code loads it when a task matches its description.
Run `npx skills add spec-kitty/spec-kitty --skill spk-start-here -a codex`. Or copy the skill folder (src/charter/offering/skills/spk-start-here in spec-kitty/spec-kitty) into .agents/skills/spk-start-here in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add spec-kitty/spec-kitty --skill spk-start-here -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/spk-start-here, .gemini/skills/spk-start-here, .github/skills/spk-start-here and .opencode/skills/spk-start-here in your project.
SKILL.md names no scripts, command-line tools or credentials: Spk Start Here is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Spk Start Here is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 550 tokens (SKILL.md is roughly 2.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Spk Start Here: MCP Server Builder (anthropics/skills, 180k stars), Hook Development for Claude Code Plugins (anthropics/claude-plugins-official, 38k stars), Using Superpowers (farm-fe/farm, 5.6k stars) and Executing Plans Inline (obra/superpowers, 296k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
