What it does
Project Maintenance is an agent skill from GoogleChrome/modern-web-guidance-src. Routine maintenance notes: checking vendored deps, web-features/compat dataset updates, and doc coherence.
Its SKILL.md is about 330 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The licence is Apache-2.0.
Example prompts
- “/project-maintenance”
What it can do on your machine
Read from SKILL.md and the folder at commit c312847. 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:
nodenpmpnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm and pnpm, which can reach the network depending on how they are called.
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
Project Maintenance loads about 329 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 80 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.

Repository Maintenance
Things that should happen with some regularity across the repository:
Vendored Dependencies
Check if upstream packages have newer releases than what we vendored:
echo "Upstream: $(npm info @vercel/detect-agent version)" && echo "Vendored: $(grep -o 'detect-agent@[0-9.]*' serving/skills-cli/telemetry/detect-agent.ts)"If updated, sync changes to serving/skills-cli/telemetry/detect-agent.ts, bump the version comment, and run node --test serving/skills-cli/telemetry/detect-agent.test.ts serving/skills-cli/telemetry/ClearcutLogger.test.ts.
Web Standards & Compatibility Datasets
web-features: Automated via.github/workflows/update-web-features.yml(Mon/Thu). Can also be run manually withpnpm update --recursive web-features, followed byguides/generate-feature-to-groups.tsandguides/validate-after-web-feature-update.ts.- Compat & WebRef: Periodically bump
