Agent Skills in Lovable: build a reusable workflow library

Stop pasting the same operating instructions into every chat. Give an agent a reviewed, versioned skill for one job, then show exactly which instructions it used.

Stop pasting the same operating instructions into every chat. Give an agent a reviewed, versioned skill for one job, then show exactly which instructions it used.

A skill packages instructions, examples and supporting resources. It is not a tool permission or a new model. Progressive disclosure loads a small catalogue first and detailed instructions only when relevant. Build this pattern in a Lovable app for customer-research briefs: select a reviewed skill, collect its required inputs, produce a structured result and keep the skill version with the run. Compatibility with external coding agents requires implementing their format and runtime, not just adding a skills table.

Parts
  • Versioned skills, resources, test_cases and runs
  • Catalogue with name, description and required inputs
  • Server-side skill selection and allowed-tool policy
  • Run viewer with version, evidence and review status
How it makes money

Use it as an internal operations library or a managed service for repeatable client briefs. Sell reviewed workflows and maintenance, not a promise of autonomous expertise. Measure correction time against your manual baseline.

Step by step
  1. Start with one skill: turn interview notes into an evidence-backed customer brief. Define required inputs and the expected output schema.
  2. Save each skill version separately with instructions, examples, resources, allowed tools and review status. Only reviewed versions can run.
  3. Load names and descriptions into the selector, not every document. Validate the selected skill ID and user access on the server.
  4. Load the selected instructions and only relevant resources. Keep uploaded material as untrusted data, never as higher-priority instructions.
  5. Keep runtime tool authorization separate from the skill text. A sentence in a skill cannot grant permission to read another user's files.
  6. Store skill version, input references and output on every run. Let users inspect sources and correct the result before export.
  7. Create fixture interviews with known facts. Compare missing evidence, invented quotes and output validity before promoting a new version.
  8. Offer rollback to the last reviewed version. Block unreviewed imported scripts; do not run arbitrary packages or shell commands.
Build a reviewed skill library for a customer-research agent. Tables: skills, immutable skill_versions, resources, test_cases and runs, scoped to each workspace. Start with one skill that turns interview notes into a structured customer brief with evidence references. Select by catalogue name and description, then load only the chosen reviewed version and relevant resources. Validate selected IDs and user access server-side. Skill instructions cannot override runtime tool permissions. Treat uploaded notes as untrusted data. No arbitrary script execution. Save version and inputs on every run; add evidence review, regression comparison and rollback to a reviewed version.

Example: interviews into a customer brief

Give the skill three interviews. Require each pain point to include an interview ID and supporting quote. If no person discussed pricing, the pricing section must say insufficient evidence. A second skill can turn the reviewed brief into a landing-page draft, but it cannot silently change the source claims. This separates a useful workflow from a long prompt that merely sounds confident.

Questions about this workflow

Are skills the same as MCP tools?
No. Skills explain how to perform a workflow. Tools provide callable capabilities. Your server still decides who may call each tool, regardless of what a skill says.
