Install

Skills CLI

npx skills add martinffx/atelier

Asks which skills and agents to install. Just one: npx skills add martinffx/atelier --skill atelier-orchestrator — add -g for every project.

Claude Code

git clone https://github.com/martinffx/ateliercp -r "atelier/skills/atelier-orchestrator" ~/.claude/skills/

Copies the atelier-orchestrator skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add martinffx/atelier

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

What it does

Filter skills

In the author's own words, from each skill's SKILL.md.

atelier-orchestrator

Skill routing and workflow orchestration. Selects Inline Plan or Spec-backed Plan, routes to the correct workflow skill, and manages transitions between phases. Use when starting any conversation or task to determine which planning mode and skill apply.
skills/atelier-orchestrator/SKILL.md on GitHub (opens in a new tab)
atelier-setup

Configure a repository for Atelier's development workflow. Use only when explicitly invoked; inspect existing guidance, issue-tracker and domain-document conventions, preview the proposed configuration, and write only after approval. It does not install Atelier or initialize external tooling.
skills/atelier-setup/SKILL.md on GitHub (opens in a new tab)
code-commit

Generate and validate conventional commit messages following the conventionalcommits.org spec. Use whenever the user wants to commit code, mentions commit messages, git commit, or asks to create a commit. Triggers on "commit", "git commit", "conventional", or when reviewing commit message format.
skills/code-commit/SKILL.md on GitHub (opens in a new tab)
code-handoff

Compact the current conversation into a handoff document for another agent to pick up.
skills/code-handoff/SKILL.md on GitHub (opens in a new tab)
code-pull-request

Manage GitHub pull requests or GitLab merge requests: create, read/leave/respond to comments, and merge. Triggers on "open a PR", "make a PR", "merge this PR", "merge the MR", "read PR comments", "leave a comment on the PR", "respond to a comment", "ship this", or when a feature branch is ready for review.
skills/code-pull-request/SKILL.md on GitHub (opens in a new tab)
code-review

Multi-agent code review run as a debate. Critics raise findings in parallel, an Author defends the change, Critics concede or maintain, and a Judge rules on what stays contested. Findings are classified by kind and blocking, and handled durably when previously decided. Use `rq` to request a review of diffs (defaults to main branch), `rs` to respond to findings and record intentional non-fix decis…
skills/code-review/SKILL.md on GitHub (opens in a new tab)
code-subagents

Implementation subagent dispatch patterns. Use when a task's design is settled and the file just needs to be made, or when independent implementation work can run in parallel. Covers eligibility, dispatch, shared-tree patch snapshots, one combined review per completed batch, and serial integration.
skills/code-subagents/SKILL.md on GitHub (opens in a new tab)
oracle-codebase-design

Shared vocabulary and principles for designing deep modules. Use when designing or changing a module's interface, deciding where a seam goes, handling untrusted input at the edges, choosing the level to test at, naming modules, or making code more testable. Also use when another skill needs the deep-module vocabulary.
skills/oracle-codebase-design/SKILL.md on GitHub (opens in a new tab)
oracle-debug

Disciplined debugging methodology. Triggers on bug reports, test failures, "debug this", "diagnose this", unexpected behavior, build failures, integration issues, or performance regressions. Find root cause before a permanent corrective fix; contain urgent harm safely first.
skills/oracle-debug/SKILL.md on GitHub (opens in a new tab)
oracle-domain-modelling

Build and sharpen a project's domain model. Use when the user wants to pin down domain terminology or a ubiquitous language, record an architectural decision, or when another skill needs to maintain the domain model.
skills/oracle-domain-modelling/SKILL.md on GitHub (opens in a new tab)
oracle-grill-me

Grill the user relentlessly about a plan, decision, or idea, maintaining the project's domain model (CONTEXT.md, ADRs) as decisions crystallise. Use when the user wants to stress-test their thinking, or uses any 'grill' trigger phrases.
skills/oracle-grill-me/SKILL.md on GitHub (opens in a new tab)
spec-brainstorm

Conversational design workshop for substantial work. Interviews the human one question at a time, explores 2-3 approaches with trade-offs, and presents the design section by section for approval before writing only design.md, then stops. Combines requirements discovery with codebase research and architecture design. Use when the user explicitly requests a spec or when atelier-orchestrator selects…

spec-finish

Post-implementation completion workflow for Spec-backed Plans. Use after spec-implement completes to validate, review, create stacked commits, and open a PR via code-pull-request. Triggers only with an active Spec-backed Plan after spec-implement completes, including when the user says "finish", "done", or "complete" in that context.
skills/spec-finish/SKILL.md on GitHub (opens in a new tab)
spec-implement

Continue an approved Spec-backed workflow when the user says "implement", "go", "start", or "do it". After Codex Plan Mode, persist the next missing design.md or plan.json artifact and stop. When both artifacts exist, execute plan.json with TDD and report between batches.
skills/spec-implement/SKILL.md on GitHub (opens in a new tab)
spec-loop

Run an approved Spec-backed Plan (design.md and plan.json both present) unattended to a draft PR: implement and review each batch with fresh subagents, commit, then finish with one whole-branch review. Use when the user says "run it to the end" or "implement everything and open a PR".
skills/spec-loop/SKILL.md on GitHub (opens in a new tab)
spec-plan

Write approved implementation plans in one of two modes. Explicit Inline mode creates a conversational plan for bounded work. Spec-backed Plan converts an approved design.md into plan.json. Both modes stop after producing their plan output. Trigger after atelier-orchestrator selects a mode, when the user asks to plan work, or after spec-brainstorm completes. Direct invocation without a selected m…

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
