mastermind-env

mastermind-env is a skill for Claude Code, Codex from monoes/monomind. It costs 37 tokens per session (1,551 once invoked), scanned A, original, Apache-2.0.

An organisation environment audit and settings tool for agent providers, memory, authentication tokens, logging, and storage. It can show, set, or validate these configuration areas.

In plain words
What is it for?
Use it to inspect or validate an organisation's runtime configuration and set a configuration key using an environment-variable reference.
Why use it?
It helps reveal missing or incorrectly configured values before agents rely on them, while allowing settings to refer to environment variables rather than inline secrets.

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

mastermind-env scanned grade A with 1 finding 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 2d 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.

The opening of the file, as written. The whole thing — 191 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mastermind Env

This skill is invoked directly via /mastermind-env.


Inputs

  • brain_context: BRAIN CONTEXT block
  • org_name: org to inspect env for
  • action: show | set | validate
  • key: env var key to set (for set action)
  • value: value to set (for set action — use env var reference, not inline secrets)
  • section: llm | memory | jwt | logging | storage | all (default: all)
  • caller: command | master

Step 0 — Brain Load (standalone only)

If caller is not "command", load brain context following mastermind-protocol/SKILL.md Brain Load Procedure with namespace: ops.


Step 1 — Load Org Config

orgFile=".monomind/orgs/${org_name}.json"
[ ! -f "$orgFile" ] && { echo "ERROR: Org '$org_name' not found."; exit 1; }

memNs="org:${org_name}"

Step 2 — Execute Action

show (default)

Collect and display environment configuration for this org's agents:

echo "╔══════════════════════════════════════════════════════╗"
echo "║  ENV AUDIT — org: ${org_name}"
echo "╚══════════════════════════════════════════════════════╝"
echo ""

# LLM / Adapter config
echo "LLM PROVIDER"
echo "────────────"
ceo_model=$(jq -r '.run_config.ceo_adapter // "claude-sonnet-5"' "$orgFile")
echo "  CEO adapter model:  $ceo_model"
jq -r '(.roles // [])[] | "  \(.id): \(.adapter_config.model // "inherited from CEO")"' "$orgFile" 2>/dev/null
echo ""

# API key availability (check env vars, never print values)
echo "API KEYS (present/missing)"
echo "──────────────────────────"
for key in ANTHROPIC_API_KEY OPENAI_API_KEY GOOGLE_API_KEY; do
  if [ -n "${!key}" ]; then
    echo "  $key: ✓ present (${!key:0:6}***)"
  elif [ -f ".monomind/orgs/.secrets/${org_name}/${key}" ]; then
    echo "  $key: ✓ in org secrets"
  else
    echo "  $key: ✗ MISSING"
  fi
done
echo ""

# Memory config
echo "MEMORY"
echo "──────"
echo "  namespace: org:${org_name}"
npx monomind@latest memory list --namespace "org:${org_name}" 2>/dev/null | wc -l | xargs echo "  stored entries:"

# Run config

jq -r '.run_config | to_entries[] | "  \(.key): \(.value)"' "$orgFile" 2>/dev/null

jq -r '"  policy: \(.governance.policy // "auto")"' "$orgFile" 2>/dev/null
echo ""

# Dashboard
echo "DASHBOARD"
echo "─────────"
CTRL_URL=$(jq -r '.url // "http://localhost:4242"' ".monomind/control.json" 2>/dev/null || echo "http://localhost:4242")
echo "  url:    $CTRL_URL"

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.
