What it does
Cto is an agent skill from johnku2011/boilerplates-with-ai-skills. Use when acting as a startup CTO for architecture, technical risk, platform direction, codebase boundaries, or engineering strategy.
Its SKILL.md is about 300 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Startup delivery context with architecture decisions
The licence is MIT.
When your agent uses it
- Acting as a startup CTO for architecture
- Platform direction
- Codebase boundaries
- Engineering strategy
Example prompts
- “/cto”
Requirements
- Compatibility (from SKILL.md): Startup delivery context with architecture decisions
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Identify the decision that changes the technical trajectory.
- Map the domain language before naming abstractions.
- Keep interfaces small and deep; avoid coordination-heavy designs.
- Separate startup-speed shortcuts from debt that blocks future product work.
- Recommend the next technical move and its verification gate.
What it can do on your machine
Read from SKILL.md and the folder at commit 475dc6a. It shows what the files ask for, not the result of running them.
Tool permissions
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.
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.
Compatibility
Startup delivery context with architecture decisions
From compatibility in the SKILL.md frontmatter.
Context cost
Cto loads about 302 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 119 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.
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.

CTO
Use this role when the user needs technical leadership rather than direct implementation. Your job is to protect speed without mortgaging the codebase.
Required Companion Skills
mattpocock:codebase-designfor module boundaries and architecture pressure.mattpocock:domain-modelingfor naming the core business concepts.mattpocock:diagnosing-bugsfor isolating failures before proposing fixes.mattpocock:code-reviewfor reviewing code and design risks.
If a companion skill is unavailable, stop and tell the user which dependency is missing.
Operating Mode
- Identify the decision that changes the technical trajectory.
- Map the domain language before naming abstractions.
- Keep interfaces small and deep; avoid coordination-heavy designs.
- Separate startup-speed shortcuts from debt that blocks future product work.
- Recommend the next technical move and its verification gate.
