brownfield-driftEnforces architecture boundaries defined in PLAN.md. An agent skill from wednesday-solutions/ai-agent-skills.
Brownfield Drift is an agent skill from wednesday-solutions/ai-agent-skills. Enforces architecture boundaries defined in PLAN.md. Use when a PR crosses module/service boundaries, when the dev asks "are we following the architecture?", or as a scheduled architecture health check. Not for querying what a module does — use brownfield-chat for that.
Its SKILL.md is about 670 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 Backend & APIs, covering Microservices. The repository describes itself as: Pre-configured agent skills for Vibe Coded projects. These skills provide AI coding assistants (Claude Code, Cursor, etc.) with specific guidelines for code quality and design… The licence is MIT.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 80fa195. It shows what the files ask for, not the result of running them.
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.
No scripts in the folder and no shell commands in SKILL.md (its code samples are json and bash).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Brownfield Drift loads about 669 tokens when it runs. Until then it costs about 72 tokens; SKILL.md has 226 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.
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.

Enforces architecture boundaries defined in PLAN.md. An agent skill from wednesday-solutions/ai-agent-skills. Brownfield Drift is an agent skill from wednesday-solutions/ai-agent-skills.md.
Brownfield Drift fits situations like: A PR crosses module/service boundaries; the dev asks are we following the architecture?; as a scheduled architecture health check.
Run `npx skills add wednesday-solutions/ai-agent-skills --skill brownfield-drift -a claude-code`. Or copy the skill folder (skills/brownfield-drift in wednesday-solutions/ai-agent-skills) into .claude/skills/brownfield-drift in your project. Claude Code loads it when a task matches its description.
Run `npx skills add wednesday-solutions/ai-agent-skills --skill brownfield-drift -a codex`. Or copy the skill folder (skills/brownfield-drift in wednesday-solutions/ai-agent-skills) into .agents/skills/brownfield-drift in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add wednesday-solutions/ai-agent-skills --skill brownfield-drift -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/brownfield-drift, .gemini/skills/brownfield-drift, .github/skills/brownfield-drift and .opencode/skills/brownfield-drift in your project.
SKILL.md names no scripts, command-line tools or credentials: Brownfield Drift is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Brownfield Drift is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 669 tokens (SKILL.md is roughly 2.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
