How to write and validate a role definition - required structure, the tier system, and the line budget.

  • Development work in your project
  • SKILL.md covers Frontmatter, Structure, The line budget and Choosing a tier, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Authoring Roles is an agent skill from oocx/tfplan2md. How to write and validate a role definition - required structure, the tier system, and the line budget.

Its SKILL.md is about 690 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. The repository describes itself as: Convert terraform plans (json) into human readable markdown for easier review of changes in pull requests. The licence is MIT.

When your agent uses it

  • Development work in your project

Example prompts

  • “/authoring-roles”

What it can do on your machine

Read from SKILL.md and the folder at commit 88d5240. It shows what the files ask for, not the result of running them.

  • Tool permissions

    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.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml, markdown and bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Authoring Roles loads about 686 tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 254 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~30
When it runs · the whole SKILL.md, loaded when a task matches
~686

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.

Safety

Auto-check passed

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); files beside SKILL.md are not scanned.

Authoring Roles

Role definitions live in .agents/roles/*.md and are generated into .claude/agents/ by scripts/sync-agent-config.sh. Edit the canonical files; never the generated ones.

Frontmatter

yaml
---
name: Code Reviewer          # display name, used in work-protocol entries
description: ...             # <= 100 chars, one line
tier: deep                   # deep | standard | cheap
---

That is the whole schema. A role must not declare:

  • model — the tier resolves to a model through .agents/tiers.json. Naming a model in a role file puts the mapping in thirteen places instead of one, and the generator rejects it.
  • tools — roles run with the harness default toolset. Per-role tool lists were the single largest source of drift in the previous corpus, because a tool ID renamed upstream broke a role silently.
  • handoffs or target — sequencing lives in state.json and .agents/workflow.json.

Structure

markdown
# Role Name

Read [AGENTS.md](../../AGENTS.md) and the `agent-runtime` skill first.

## Goal            <!-- one sentence: the outcome, not the process -->
## Boundaries      <!-- Always / Never; Ask first only where it is real -->
## Inputs          <!-- what to read, and in what order -->
## Steps           <!-- numbered, with exact commands -->
## Output          <!-- artifact paths and their shape -->
## Definition of Done

scripts/validate-agents.py enforces ## Goal, ## Boundaries, ## Definition of Done, and a reference to AGENTS.md.

The line budget

160 lines, enforced. A role that outgrows it is doing more than one job, or is repeating something that belongs in AGENTS.md (project-wide rules) or the agent-runtime skill (how roles operate). The previous corpus averaged 378 lines per agent, and almost all of the excess was duplicated boilerplate.

Write only what is true of this role and no other.

Choosing a tier

TierUse for
deepWork whose errors propagate — requirements, architecture, review, the workflow itself
standardWork constrained by an approved spec, where mistakes surface in review or CI
cheapTranscription and mechanical work against a fixed input

Cost is a consideration, but the deciding question is what an error costs to unwind. A role escalates one tier automatically on rework, so the tier is the starting point, not a ceiling.

Before committing

bash
scripts/sync-agent-config.sh     # regenerate .claude/
scripts/validate-agents.py       # structure, tier, budget, links, adapter drift
