arxivist: Skill for Claude Code

.claude/skills/agent-config/SKILL.md

agent-config is a skill for Claude Code from agentculture/arxivist. It costs 124 tokens per session (987 once invoked), scanned A, a copy of agent-config, MIT.

A read-only view of one coding agent’s instructions, runtime settings, and installed project skills. It shows the files that define how the agent behaves and what tools it can use.

In plain words
What is it for?
Use it to review an agent’s current setup before teaching it a task or checking what configuration and skills it has.
Why use it?
It removes the need to open several configuration files separately when inspecting or onboarding an agent.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions AGENTS.md.

This is agentculture/arxivist's own configuration. It tells Claude Code how to work on arxivist itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything arxivist configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is .claude/skills/agent-config/scripts/show.sh ../culture.

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

agent-config 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 6d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/show.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Origin

How it starts

The opening of the file, as written. The whole thing — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.

agent-config — surface a Culture agent's config in one view

guildmaster is the mesh's skills supplier and owns the inventory surfaces: "what kit + config does this agent have?" This skill answers exactly that for a single agent, showing the three artifacts that together define it:

  1. System-prompt file (CLAUDE.md / AGENTS.md / GEMINI.md) — the prompt-side guidance for the agent's backend. The script detects which file is present from a backend-fingerprint registry.
  2. culture.yaml — the runtime-side config (agents: list with suffix, backend, model, system_prompt, channels, tags, acp_command, extras). Lives parallel to the prompt file at the project root.
  3. .claude/skills/*/SKILL.md — the per-project skills the agent can invoke, one line each (name + truncated description).

This is the inventory half of the steward → guildmaster split (issue #12): it reports the config, it does not interpret drift or judge alignment. The relationship graph and the "is this agent aligned?" judgment stay with steward overview / steward doctor.

When to use

  • Before guild teach / guild onboard — see an agent's current kit + config.
  • When an operator asks "show me agent <name>" or "what does <agent> run".
  • Read it, don't guess — before answering a question about what an agent does.

How to run

One script, two ways to call it (or just run guild show, which wraps it):

# Path mode — point at any directory with a prompt file + culture.yaml
.claude/skills/agent-config/scripts/show.sh ../culture

# Suffix mode — resolve a registered agent suffix via the Culture server's
# manifest (location set by culture_server_yaml in skills.local.yaml)
.claude/skills/agent-config/scripts/show.sh daria

Output is three sections: the detected system-prompt file, culture.yaml (or (missing)), and a one-line summary per local skill (name + description, truncated to 120 chars).

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
