model-citizen
The control plane for your coding agents, however you run them. One checkout of rules, skills, subagents, hooks and stances, projected into Claude Code and Codex with your own primitives: hook-enforced guardrails, usage telemetry, cost postures and model tiering, under any rules library or orchestration layer.

Install
Skills CLI
npx skills add JakeSelby/model-citizen
Asks which skills and agents to install. Just one: npx skills add JakeSelby/model-citizen --skill api-verification — add -g for every project.
Claude Code
git clone https://github.com/JakeSelby/model-citizencp -r "model-citizen/primitives/skills/api-verification" ~/.claude/skills/
Copies the api-verification skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.
Plugin
/plugin marketplace add JakeSelby/model-citizen
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
In the author's own words, from each skill's SKILL.md.
-
api-verification
Prove a search, filter or API answer is real before relying on it, and budget web search across a fan-out. Use when querying an unfamiliar API, a filter returns suspiciously clean results, a per-item error may have been swallowed, or briefing research agents.
primitives/skills/api-verification/SKILL.md on GitHub (opens in a new tab) -
architecture-viewer
Open or update an architecture diagram with the selected builtin or custom viewer, preserving a neutral session handoff. Use when asked to inspect architecture interactively or continue an existing diagram session.
primitives/skills/architecture-viewer/SKILL.md on GitHub (opens in a new tab) -
code-quality-instruments
Measure whether a test suite is any good, not only that it passes: branch coverage, mutation score, complexity-times-coverage risk, duplication. Use when adding or reviewing tests on a change that matters, a suite passes but a bug still shipped, coverage is high and confidence is not, or before promising a module is well tested.
primitives/skills/code-quality-instruments/SKILL.md on GitHub (opens in a new tab) -
delegation-tiering
Decide whether to spawn a subagent, and on which model tier and reasoning effort. Use when planning a fan-out, choosing a subagent model, writing a workflow script's opts.model, authoring an agent definition, setting a repo's cost posture, or when a delegation decision is non-obvious.
primitives/skills/delegation-tiering/SKILL.md on GitHub (opens in a new tab) -
design-loop
Raise the visual quality of something that already renders: build, screenshot, independent scored critique, fix, against rubrics with hard accessibility, design-token, runtime and asset-licensing gates. Use when asked to make a UI, page, HTML doc, dashboard, game scene or 3D asset look dramatically better, more polished or more professional; to improve the visual design, look, styling or visual q…
primitives/skills/design-loop/SKILL.md on GitHub (opens in a new tab) -
harness-authoring
Decide where an instruction belongs and write it there, then sync and lint. Use when asked to add, change or remove a rule, skill, instruction, hook, setting or CLAUDE.md line, to "remember" something that should persist beyond this session, or when a correction should apply to future sessions.
primitives/skills/harness-authoring/SKILL.md on GitHub (opens in a new tab) -
licensing-review
Verify a third-party library, asset, model, font, dataset or copied snippet is safe to ship under the project's licensing stance, and record it. Use before adding or upgrading any dependency, before downloading any asset, and before a release.
primitives/skills/licensing-review/SKILL.md on GitHub (opens in a new tab) -
migration-safety
Write, review or apply a database schema migration without destroying data. Use for any task that creates or modifies a migration file (Alembic, Prisma, Django, Rails, Flyway, raw SQL), and before applying one to a shared environment.
primitives/skills/migration-safety/SKILL.md on GitHub (opens in a new tab) -
plan-authoring
Write or revise a plan file, proposal, design doc or handoff the user reviews before approving work; carries the Review Card contract and the addendum rules. Use before writing anything into .agent-harness/plans/, and for any markdown deliverable whose job is to get a go/no-go.
primitives/skills/plan-authoring/SKILL.md on GitHub (opens in a new tab) -
sandbox
Fence an autonomous or long-running agent loop: the built-in sandbox with network off, or a container with the worktree mounted. Use before any unattended loop, before `execute` autonomy on an unfamiliar repo, and whenever a task pulls untrusted input.
primitives/skills/sandbox/SKILL.md on GitHub (opens in a new tab) -
spike-contract
Frame a spike so its result is a decision: the question, the cheapest experiment, a numeric exit criterion, the measured result, the machine it ran on. Use when asked to "spike", "prototype to find out", "de-risk", or "check whether X is feasible", and when writing the spikes section of a plan or README.
primitives/skills/spike-contract/SKILL.md on GitHub (opens in a new tab) -
transcript-hygiene
Bound what subagents return and what tool output enters the transcript; load when briefing a subagent or reading large output.
primitives/skills/transcript-hygiene/SKILL.md on GitHub (opens in a new tab) -
upstream-contribution
Contribute from a fork to a repository you do not own without burning maintainer trust. Use when the working repo has an `upstream` remote, when the user says "open a PR against <someone else's repo>", or before the first commit in any repo the user is a guest in.
primitives/skills/upstream-contribution/SKILL.md on GitHub (opens in a new tab) -
workflow-status
Show progress of background Workflow runs: who has returned, who is still working, how much output. Use when the user asks about workflow progress, says "/workflows doesn't work", asks "is the workflow done", "how's the workflow going", "check the workflow", or wants to inspect a multi-agent orchestration run.
primitives/skills/workflow-status/SKILL.md on GitHub (opens in a new tab) -
worktree-per-agent
Isolate an agent's work in its own git worktree branched off the default branch, so two agents never land conflicting changes on the shared checkout. Use at the start of any implementation task in a repo where others may also be working, and whenever a repo's instructions say "work in a worktree".
primitives/skills/worktree-per-agent/SKILL.md on GitHub (opens in a new tab)
No skill matches that filter.
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.
