What it does

Progressive Building is an agent skill from n8n-io/n8n, published by the product's own GitHub organization. Load before build-workflow and before scoping or planning new workflows and feature additions, including requests spanning multiple workflows. Implement one increment per user message. Finish setup and inspect a successful real execution before offering another increment. Then wait for the next user reply. Partial setup is incomplete. A first setup or test refusal pauses building. Follow the skill's full-build exceptions. Also supports workflow edits and repairs. For workflows that create or write Data Tables…

Its SKILL.md is about 1.6k 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 Productivity & Automation, covering Workflow automation. It works with n8n and Model Context Protocol. The repository describes itself as: Fair-code workflow automation platform with native AI capabilities. Combine visual building with custom code, self-host or cloud, 400+ integrations.

6 steps, taken from the first numbered list in SKILL.md.

What it can do on your machine

Read from SKILL.md and the folder at commit 7424f0c. 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

Progressive Building loads about 1.6k tokens when it runs. Until then it costs about 166 tokens; SKILL.md has 846 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~166
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

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 846 words (~1,591 tokens).

“Apply this policy when creating or extending workflows and repairing those builds. It overrides conflicting scoping and setup narration in the building and post-build guidance above. Keep their validation, approval, credential, publish, and cleanup rules. Write to the user in…”
