product-plugins

Use when reviewing a pull request, to check for logic bugs, style consistency, and security concerns and summarise the findings for the author.

Use once there is a confirmed composition plan, to create it. Scaffolds the plugin, authors or restructures the skill(s), decomposes anything too big, and adds any rules or MCP servers the plan called for. Uses the CLI to scaffold the plugin, then adds further skills by hand.

Database administration tasks including schema changes, backups, monitoring, and user access management.

Use when someone wants to turn a problem, a messy or sprawling skill, or some existing work into well-shaped reusable context for their agent. Triggers include "help me make a skill for X", "my skill is a mess, sort it out", "I want to get more out of Tessl with this skill", or "package this so my team can use it". Runs the arc - understand the problem, gather the artifacts, plan the right composition, build it - then points to eval as a separate next step.

Use during build when a skill or a problem is too big for one skill - a sprawling SKILL.md doing several jobs, or a large problem the user wants a single skill for. Splits it into focused, independently-verifiable skills, with a plugin as the superstructure that holds them together.

Use at the start of creating context, to understand the problem the user is solving and take stock of what they already have. The user may arrive with an existing skill or plugin, code, a written prompt or transcript, or nothing but a pointer ("go look at my PRs"). Gathers what exists and fills the gaps - by asking or by hunting - until there is enough to plan a composition.

Use once the problem and artifacts are understood, to decide the right shape for the context. Produces a short composition plan - a single skill for simple cases, or a plugin (with rules, commands, MCP servers, or multiple skills) for richer ones - and confirms it with the user before anything is built.

Use when a composition is built and the user wants to share it, to publish or re-publish it to the Tessl registry. Lints it, confirms private/public visibility, and publishes.

Scaffold and author a custom Tessl reviewer plugin, by forking the default rubric or building one from scratch. Fetches the published default Tessl review rubric (tessl/default-skill-review) so you can read and tweak it, scaffolds the plugin directory, writes rubric files and config.json, and validates with tessl review run. Use when the user wants to create or customise a review plugin, fork or tweak the default reviewer rubric, change scoring weights, add custom judges, or build a domain-specific rubric for tessl review.

Evaluate a SKILL.md for quality. An agent that dynamically discovers the rubric files and scores the skill against each, producing one result per rubric. Use when running a skill review workflow or testing skill quality against configurable rubrics.

Add an endpoint to the backend.

Derive custom review-plugin judges, rubrics, and scoring criteria from evidence — existing skills, PR review feedback, and accumulated agent logs — by finding where agents needed correction or skills failed to activate, then translating those patterns into scoring dimensions and anchors. Hands the rubric design to create-review-plugin for scaffolding. Use when the user wants a custom skill reviewer or scoring rubric grounded in how their agents actually behave — to grade skills consistently, or build review criteria from past PR feedback and agent logs.

Find and call Tessl API endpoints. Use this WHENEVER you need a Tessl REST API endpoint — to discover which endpoint does something, to learn an endpoint's path, parameters, request body shape, or response shape, or to actually call the Tessl API. Reach for this skill INSTEAD OF reading the raw `openapi.json` spec.
