What it does
Context Window is an agent skill from thedaviddias/ux-patterns-for-developers. Use when implementing managing AI conversation context.
Its SKILL.md is about 1000 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/pattern.md`).
It sits in Agent Workflows, covering Context engineering and Accessibility. The repository describes itself as: 🧩 Developer ecosystem for UX patterns: comprehensive docs, ready-to-use components, and real-world examples.
When your agent uses it
- Implementing managing AI conversation context
- Tasks that involve Context engineering
- Tasks that involve Accessibility
Example prompts
- “/context-window”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Confirm the pattern matches the problem and constraints before copying the example.
- Start from the anatomy and examples in references/pattern.md, then choose the smallest viable variation.
- Apply accessibility, performance, and interaction guardrails before layering visual polish.
- Use the testing guidance to verify behavior across keyboard, screen reader, responsive, and failure scenarios.
What it can do on your machine
Read from SKILL.md and the folder at commit a15991d. 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
Links to these hosts (documentation or services it may open):
uxpatterns.dev
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
Context Window loads about 995 tokens when it runs, and up to ~4.1k if it reads all its reference files. Until then it costs about 18 tokens; SKILL.md has 474 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 474 words (~995 tokens).
