Claude Code Agent Development

Explains how to write agents for Claude Code plugins: the markdown file with YAML frontmatter, trigger descriptions, model and color settings, and system prompt design.
Put an idea on trial: a prosecutor and a defense Claude argue, 12 juror sub-agents vote independently, and a judge reads the verdict and the changes that would flip it.

Court is an agent skill from sickn33/agentic-awesome-skills. Put an idea on trial: a prosecutor and a defense Claude argue, 12 juror sub-agents vote independently, and a judge reads the verdict and the changes that would flip it.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts and reference files (for example `references/jurors.json` and `scripts/court.py`).
It sits in Agent Workflows, covering Subagents. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit b84d35a. It shows what the files ask for, not the result of running them.
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.
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3From the folder's file list and the shell code blocks in SKILL.md.
Links to these hosts (documentation or services it may open):
instagram.comgithub.comFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Court loads about 1.5k tokens when it runs, and up to ~2k if it reads all its reference files. Until then it costs about 44 tokens; SKILL.md has 859 words of instructions outside code blocks.
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.
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); the scripts in this folder are not scanned.

.claude/skills/court/SKILL.md (or your agent's skills folder). This skill also uses 2 other files; get the full folder from GitHub.For when Claude agrees with everything you say. Instead of one polite answer, the idea goes on trial: a prosecutor builds the case against it, a defense builds the case for it, and a jury of Claudes who never see each other votes. You are the clerk of the court. You never argue, never vote, and never soften the verdict.
What the user typed after /court: $ARGUMENTS
If that is blank, or still reads like a placeholder, take the case from the conversation: the idea, plan or claim the user most recently wanted an opinion on.
Every piece of bookkeeping goes through scripts/court.py in this skill's folder:
python3 "${CLAUDE_SKILL_DIR}/scripts/court.py" <command>Below, COURT means exactly that command. If the path looks unexpanded, use the "Base directory for
this skill" that Claude Code printed at the top of this skill. The state lives in
.court/<run>/state.json in the current directory, and every command after init finds it through
.court/LATEST.
Read the flags out of the request. Everything that is not a flag is the case.
| flag | meaning |
|---|---|
--jury N | N jurors, 3 to 12. Default 12. |
--quick | 6 jurors. |
--seed S | Fixes which jurors sit on a smaller jury. Default: random, and recorded. |
Run COURT plan with the same flags and tell the user in one line how big the trial is, for example
"12 jurors, 17 sub-agent calls", then start. If this skill fired on its own (the user never asked for
a trial), ask once first and offer --quick.
Sub-agents write into .court/ in the current directory. In the default permission mode that is one
approval per file. Suggest accept-edits mode (Shift+Tab) for the trial. Do not change the user's
settings yourself.
Sub-agents cannot see this conversation. The prosecutor, the defense, every juror and the judge
know only what is in the case file, so write .court/case.md to stand on its own:
COURT init --case-file .court/case.md [--jury N | --quick] [--seed S]Always drive it with COURT next. It reads the files on disk and tells you the next phase and the
exact command. The phases run in this order: opening, rebuttal, jury, judge.
Every phase works the same way:
COURT prompts <phase> writes one brief per job and lists the jobs still to run, in waves.
Launch one wave at a time: a single message with one Agent tool call per job in that wave (the Agent tool is called Task in older Claude Code versions). Each call is:
subagent_type: general-purposedescription: court <job id>prompt: Read <brief path> and follow it exactly. It is your whole brief.Wait until every agent in the wave has replied before you launch the next wave.
After the last wave, run COURT next. If an output is missing it sends you back to the same phase,
and prompts then lists only the missing jobs. Re-run those once. If a juror fails twice, write
the single line NO VOTE into its file (COURT check jury lists it) and move on. Never write a
vote, a statement or a judgment yourself.
When COURT next says the trial is over:
COURT renderIt counts the votes, writes VERDICT.md into the run folder and prints it. Show the user the verdict
line, the vote table and the judge's sections exactly as written. Then add at most two lines of your
own: the single condition for acquittal you would start with, and the path to the full trial.
Rules for you, the clerk:
/court Quit my job to sell candles on Etsy full time. I have $8,000 saved and 40 sales so far.
/court --quick The plan you just gave me is the right one.--quick), and each counts toward the user's Claude plan usage.${CLAUDE_SKILL_DIR}).By Alex Chen (@nocodealex). Original repo with tests and a real example run: https://github.com/alexyc9381/court-skill

Court is an agent skill from sickn33/agentic-awesome-skills. Put an idea on trial: a prosecutor and a defense Claude argue, 12 juror sub-agents vote independently, and a judge reads the verdict and the changes that would flip it.
Court fits situations like: tasks that involve Subagents.
Run `npx skills add sickn33/agentic-awesome-skills --skill court -a claude-code`. Or copy the skill folder (skills/court in sickn33/agentic-awesome-skills) into .claude/skills/court in your project. Claude Code loads it when a task matches its description.
Run `npx skills add sickn33/agentic-awesome-skills --skill court -a codex`. Or copy the skill folder (skills/court in sickn33/agentic-awesome-skills) into .agents/skills/court in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add sickn33/agentic-awesome-skills --skill court -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/court, .gemini/skills/court, .github/skills/court and .opencode/skills/court in your project.
Going by SKILL.md and its folder, Court needs Python for the scripts in its folder and the command-line tools its instructions call (python3). Our summary lists: Python 3.
SKILL.md names 2 domains. As links in the text: instagram.com and github.com. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Court is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.5k tokens (SKILL.md is roughly 6.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 473 tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Court: Claude Code Agent Development (anthropics/claude-plugins-official, 38k stars), Subagent Driven Development (Asvarox/allkaraoke, 261 stars), Dispatching Parallel Agents (ultralisp/ultralisp, 258 stars) and Reflect on Session Learnings (cursor/plugins, 11k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
