What it does
Tech Trend Watch is an agent skill from mizchi/skills. Long-term technology stack review using State of JS, State of CSS, and Thoughtworks Technology Radar — satisfaction×usage matrix, ADOPT/TRIAL/ASSESS/HOLD mapping, P0–P3 migration priority. Use for annual stack audits, planning major migrations (jest→vitest, webpack→Vite, etc.), or on-demand replacement decisions. Not for general architecture design.
Its SKILL.md is about 1.8k 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 Testing & QA, covering Unit testing. It works with Jest, Vite, Vitest and webpack. The repository describes itself as: Agent skills by mizchi, distributed via APM.

What it can do on your machine
Read from SKILL.md and the folder at commit 62f5808. 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:
jqvitestjest
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:
assets.devographics.com
Also links to:
stateofjs.comstateofcss.comthoughtworks.com
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
Tech Trend Watch loads about 1.8k tokens when it runs. Until then it costs about 92 tokens; SKILL.md has 697 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 697 words (~1,847 tokens).
