add-member

add-member is a skill for Claude Code, Codex from yimwoo/codex-agenteam. It costs 21 tokens per session (1,080 once invoked), scanned A, original, MIT.

A team-management tool that adds a new AI team member from a plain-language description. It turns the requested role into configuration details such as a name, focus, and file-writing scope.

In plain words
What is it for?
Use it to add roles such as security auditor, performance engineer, documentation writer, or DevOps engineer, with responsibilities inferred from your description.
Why use it?
It avoids manually designing agent settings for every new responsibility. It can also initialize the team setup when the project does not have one yet.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

add-member scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AgenTeam Add Role

Add a new team member from a natural language description.

Process

1. Auto-Init Guard

Check for .agenteam/config.yaml, .agenteam.team/config.yaml, or legacy agenteam.yaml. If all are missing:

  • Create config dir: mkdir -p .agenteam
  • Copy the template: cp <plugin-dir>/templates/agenteam.yaml.template .agenteam/config.yaml
  • Set the team name to the project directory name
  • Generate agents: python3 <runtime>/agenteam_rt.py generate

2. Parse Intent

Extract role details from the user's natural language request. Examples:

  • "Add a performance tuning engineer" -> name: performance_engineer, focus: profiling + optimization
  • "I need a security auditor on the team" -> name: security_auditor, focus: vulnerabilities + auth
  • "Add a docs writer that maintains README and API docs" -> name: docs_writer, focus: documentation, write_scope: docs/**
  • "Add a DevOps engineer for CI/CD" -> name: devops_engineer, focus: pipelines + deployment

Infer as much as possible from the description:

Field How to infer
name Snake_case from the role title
description From user's description
responsibilities 3-5 items inferred from the role's domain
participates_in Match to pipeline stages: research, strategy, design, plan, implement, test, review
can_write Yes if the role creates/modifies files; no if it only analyzes
write_scope Infer from what the role writes (docs, src, tests, configs)
model Omit to inherit platform default. If the user requests a pin, inspect codex debug models and choose only from the live catalog. Use evaluation evidence to justify a strong model for demanding analysis or a smaller model for bounded worker tasks. Model is a personal override — share-config strips it.
reasoning_effort high for analysis roles, medium for execution/writing roles
system_instructions Generate focused instructions from the role's domain

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
