bmad-customize is a skill for Claude Code, Codex from flanliulf/SpecLite. It costs 44 tokens per session (1,613 once invoked), scanned A, a copy of bmad-customize, MIT.

A workflow for changing how installed BMad skills or agents behave by writing project-specific override files. BMad is a set of structured workflows for AI-assisted software development.

In plain words
What is it for?
Use it to customize an agent's role or a workflow's behavior, such as its instructions or communication settings.
Why use it?
It lets you adjust supported behavior without editing the installed skill itself, while checking whether the requested setting is available.

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-customize 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 7d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/list_customizable_skills.py, scripts/tests/test_list_customizable_skills.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 — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.

BMad Customize

Translate the user's intent into a correctly-placed TOML override file under {project-root}/_bmad/custom/ for a customizable agent or workflow skill. Discover, route, author, write, verify.

Scope v1: per-skill [agent] overrides (bmad-agent-<role>.toml / .user.toml) and per-skill [workflow] overrides (bmad-<workflow>.toml / .user.toml). Central config ({project-root}/_bmad/custom/config.toml) is out of scope — point users at the How to Customize BMad guide.

When the target's customize.toml doesn't expose what the user wants, say so plainly. Don't invent fields.

Preflight

  • No {project-root}/_bmad/ → BMad isn't installed. Say so, stop.
  • {project-root}/_bmad/scripts/resolve_customization.py missing → continue, but Step 6 verify falls back to manual merge.
  • Both present → proceed.

Activation

Load _bmad/config.toml and _bmad/config.user.toml from {project-root} for user_name (default BMad) and communication_language (default English). Greet. If the user's invocation already names a target skill AND a specific change, jump to Step 3.

Step 1: Classify intent

  • Directed — specific skill + specific change → Step 3.
  • Exploratory — "what can I customize?" → Step 2.
  • Audit/iterate — wants to review or change something already customized → Step 2, lead with skills that have existing overrides; read the existing override in Step 3 before composing.
  • Cross-cutting — could live on multiple surfaces → Step 3, choose agent vs workflow explicitly with the user.

Step 2: Discovery

python3 {skill-root}/scripts/list_customizable_skills.py --project-root {project-root}

Use --extra-root <path> (repeatable) if the user has skills installed in additional locations.

Group the returned agents and workflows for the user; for each show name, description, whether has_team_override or has_user_override is true. Surface any errors[]. For audit/iterate intents, lead with already-overridden entries.

Files

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.
