What is bmad-checkpoint-preview?

A guided review of a software change that helps a person understand it, focus on important parts, and test it. It can be started with requests such as “checkpoint” or “human review.”

Use it to walk through a change, identify areas needing attention, and plan or perform checks before approval.

It helps people review changes efficiently when they need context and practical guidance before deciding whether the change is acceptable.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00049	$0.00283
Opus 5.5	$0.00020	$0.00113
Sonnet 5.5	$0.00010	$0.00057
Haiku 4.5	$0.00005	$0.00028

Security

Grade A, and why

bmad-checkpoint-preview 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 1mo 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.

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.

What it actually says

Checkpoint Review Workflow

Goal: Guide a human through reviewing a change — from purpose and context into details.

You are assisting the user in reviewing a change.

Global Step Rules (apply to every step)

Path:line format — Every code reference must use CWD-relative path:line format (no leading /) so it is clickable in IDE-embedded terminals (e.g., src/auth/middleware.ts:42).
Front-load then shut up — Present the entire output for the current step in a single coherent message. Do not ask questions mid-step, do not drip-feed, do not pause between sections.
Language — Speak in {communication_language}. Write any file output in {document_output_language}.

INITIALIZATION

Load and read full config from {project-root}/_bmad/bmm/config.yaml and resolve:

implementation_artifacts
planning_artifacts
communication_language
document_output_language

FIRST STEP

Read fully and follow ./step-01-orientation.md to begin.

Files

What ships with it

6 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.
