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 C, and why

finfocus-install scanned grade C with 2 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 15d 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.

FinFocus Installation

Quick Path: Existing Install

If finfocus is already installed, prefer the built-in setup command:

finfocus setup                    # Full bootstrap (idempotent)
finfocus setup --skip-analyzer    # Without Pulumi analyzer
finfocus setup --skip-plugins     # Without plugins (offline)
finfocus setup --non-interactive  # CI/CD mode

Setup runs: version check, Pulumi detection, directory creation, config init, analyzer install, and default plugin (aws-public) install.

Full Workflow

Step 1: Check Existing Installation

finfocus --version

If installed, skip to Step 3. If not, continue.

Step 2: Install the CLI Binary

Install script (Linux/macOS):

curl -fsSL https://raw.githubusercontent.com/rshade/finfocus/main/scripts/install.sh | sh
Env Var Purpose
FINFOCUS_VERSION Pin specific version (default: latest)
FINFOCUS_INSTALL_DIR Custom install dir (default: /usr/local/bin or ~/.local/bin)
FINFOCUS_NO_VERIFY=1 Skip SHA256 checksum verification

Go install (fallback/Windows):

go install github.com/rshade/finfocus/cmd/finfocus@latest

Source build (last resort):

git clone https://github.com/rshade/finfocus.git && cd finfocus && make build

Verify: finfocus --version

Step 3: Detect Cloud Providers

Determine which plugins to install:

  1. Check for Pulumi.yaml/Pulumi.yml — scan resource type prefixes (aws:, kubernetes:)
  2. Check Pulumi state (pulumi stack export) for resource types
  3. Check filesystem: ~/.aws/, ~/.config/gcloud/, ~/.azure/, kubeconfig
  4. Default to aws-public if nothing detected

Provider-to-plugin mapping — see references/registry-plugins.md.

Step 4: Install Plugins

finfocus plugin install aws-public
finfocus plugin install opencost

What ships with it

3 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.
