What it does
Write Design Doc is an agent skill from videojs/video.js. Write or update a Video.js architecture, feature, or decision record only when the user explicitly requests that record. Use for compact, non-inferable rationale outside UI component design.
Its SKILL.md is about 390 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, covering Architecture decision records. The repository describes itself as: Video.js v10 - open source media player framework for HTML and React.
When your agent uses it
- Explicitly requests that record
- Non-inferable rationale outside UI component design
Example prompts
- “/write-design-doc”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Confirm that the user explicitly requested creation or revision of the record. Do not invoke this skill merely because a design decision…
- Use the requested artifact and path when given; otherwise choose the smallest matching design or decision location.
- Read the relevant code, tests, history, and existing record. Treat executable sources as current behavior.
- State the decision directly, then preserve only the important rationale, constraint, or trade-off that cannot be inferred from those…
- Link source, tests, or related records instead of copying APIs, schemas, state flow, file inventories, or mechanics.
- Include alternatives or consequences only when they materially explain the choice. Omit empty headings and speculative detail.
What it can do on your machine
Read from SKILL.md and the folder at commit 50f59a2. 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.
Context cost
Write Design Doc loads about 385 tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 189 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 189 words (~385 tokens).
“Read internal/design/README.md and internal/decisions/README.md; they define current placement, status, and format.”
