list-agents

list-agents is a skill for Claude Code, Codex from gettalon/talon-plugins. It costs 37 tokens per session (577 once invoked), scanned A, original, MIT.

An inspection skill finds existing agents, skills, and workflows in the workspace and can display their configurations and relationships. Agents are task-focused assistants, while workflows describe sequences of actions.

In plain words
What is it for?
It is for listing available agents and skills, inspecting an individual agent, and viewing its model, backend, skills, identity, workflow, and launch command.
Why use it?
It provides a way to discover what automation already exists before creating or choosing something new.

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

list-agents 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 4d 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.

List Agents — Discovery and Inspection

Find and display existing agents, skills, and workflows across the workspace.

Process

Step 1: Scan for Agents

Search these locations for agent definitions:

# Primary location
~/.talon/agents/*/AGENT.yaml

# Standalone skills
~/.talon/skills/*/SKILL.md

# Standalone workflows
~/.talon/workflows/*.yaml

Step 2: Display Agent Summary

For each agent found, show:

Agent: <name>
  Description: <from AGENT.yaml>
  Model: <model>
  Backend: <backend or "default">
  Skills: <count> (<skill-1>, <skill-2>, ...)
  Workflows: <count> (<workflow-1>, ...)
  Identity: <first line of SOUL.md>

Step 3: Detailed Inspection (if requested)

If the user asks about a specific agent, show:

  1. Full SOUL.md — identity and philosophy
  2. AGENT.yaml — complete configuration
  3. Skills list — each skill's name, description, and step count
  4. Workflow diagram — text representation of state machine:
    [planning] → [implementation] → [review] → [done]
                        ↑                |
                        └── (rejected) ──┘
    
  5. Launch command — how to run this agent via dispatch

Step 4: Gap Analysis (optional)

If the user asks "what's missing?" or wants to improve an agent:

  • Check if SOUL.md exists and has substance (not just template placeholders)
  • Check if skills have validation steps
  • Check if workflows pass validation
  • Check if AGENT.yaml references skills/workflows that actually exist
  • Suggest improvements based on domain best practices

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.
