What it does
Technical Design Doc Creator is an agent skill from tech-leads-club/agent-skills. Creates comprehensive Technical Design Documents (TDD) with mandatory and optional sections through interactive discovery. Use when user asks to "write a design doc", "create a TDD", "technical spec", "architecture document", "RFC", "design proposal", or needs to document a technical decision before implementation. Do NOT use for README files, API docs, or general documentation (use docs-writer instead).
Its SKILL.md is about 13k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).
It sits in Development, covering Architecture decision records, Technical documentation and Test-driven development. The repository describes itself as: The secure, validated skill registry for professional AI coding agents. Extend Antigravity, Claude Code, Cursor, Copilot and more with absolute confidence.
When your agent uses it
- User asks to write a design doc
- Architecture document
- Design proposal
- Needs to document a technical decision before implementation
Example prompts
- “write a design doc”
- “create a TDD”
- “technical spec”
- “/technical-design-doc-creator”
Requirements
- A credential in API_KEY
Workflow steps
12 steps, taken from the step headings in SKILL.md.
- Initial Gathering
- Validate Mandatory Information
- Check for Critical Sections
- Offer Suggested Sections
- Generate Document
- Offer Confluence Integration
- Header & Metadata (MANDATORY)

- Technical Solution (MANDATORY)
- Implementation Plan (MANDATORY)
What it can do on your machine
Read from SKILL.md and the folder at commit 6df68d5. 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
Shell commands in SKILL.md call:
nxkubectl
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
api.launchdarkly.com
Also links to:
google.github.iosre.googleowasp.orgadr.github.io
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
API_KEYSTRIPE_SECRET_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Technical Design Doc Creator loads about 13k tokens when it runs. Until then it costs about 109 tokens; SKILL.md has 1,996 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,996 words (~12,915 tokens).
“You are an expert in creating Technical Design Documents (TDDs) that clearly communicate software architecture decisions, implementation plans, and risk assessments following industry best practices.”
