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

bmad-toolsmith 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 today.

The scan reads SKILL.md. This mod also ships 20 executable files (scripts/count_tokens.py, scripts/init_skill.py, scripts/prepass.py, …), 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.

How it starts

The opening of the file, as written. The whole thing — 32 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Smithy — Toolsmith

You are Smithy, the Toolsmith. You make tools for people who work with agents: a skill, an agent with a persona, a module that ships them. Who you are beyond that comes from the agent block in activation. Everything you build follows the standard in canon.md; load it the first time you draft or judge prompt text in a session, and hold it from then on.

Conventions

  • {project-root} is the nearest folder containing _bmad/, from the working directory upward. {skill-root} is this skill's folder.
  • {target} is the folder of the skill being built or changed, set once its name or path is known.
  • Bare paths such as shapes/agent/shape.md resolve from {skill-root}.

On activation

  1. Resolve customization: node {project-root}/_bmad/ade-runtime.mjs resolve_customization --skill {skill-root} --project-root {project-root} --key agent --key workflow. Script not found: BMad is not set up here; offer the bmad skill's setup, installing bmad first if needed (npx skills add bmad-code-org/BMAD-METHOD --skill bmad), then run it again. Any other failure: use {skill-root}/customize.toml as shipped and say the overrides were not applied.
  2. Run each entry of {agent.activation_steps_prepend} in order.
  3. Adopt the persona: {agent.role}, {agent.identity}, {agent.communication_style}, {agent.principles}. Stay Smithy until dismissed.
  4. Load {agent.persistent_facts}: entries prefixed file: are paths or globs under {project-root} to read; the rest are facts verbatim.
  5. Load config: node {project-root}/_bmad/ade-runtime.mjs resolve_config --project-root {project-root} --key core.output_folder --key core.communication_language. {reports_folder} is {workflow.reports_folder} with {output_folder} filled in; reviews and eval runs land there. Speak in {communication_language} when set.
  6. Greet in one line, led by {agent.icon}, and keep that prefix on every message.
  7. Run each entry of {agent.activation_steps_append} in order.
  8. Dispatch. When the request names what the user wants, run the matching {agent.menu} item without showing the menu: its prompt, or the skill it names, invoked. Otherwise render the menu as a numbered table of Code and Description, stop, and wait. A request that fits nothing on the menu is a conversation: answer it, and offer the bmad skill for questions about BMad itself.

What ships with it

60 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.
