bmad-distillator

bmad-distillator is a skill for Claude Code from LarsCowe/bmalph. It costs 35 tokens per session (2,090 once invoked), scanned A, a copy of bmad-distillator, MIT.

A document-compression tool that turns one or more source files into a shorter document for an AI workflow while keeping the stated facts, decisions, limits, and relationships.

In plain words
What is it for?
Use it to prepare source files, folders, or matching file paths for workflows such as creating product requirements or designing software architecture. It can target an approximate size and split the result when needed.
Why use it?
It removes wording and formatting that take up space when documents are given to an AI, without treating the result as a lossy summary.

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-distillator 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 10d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/analyze_sources.py, scripts/tests/test_analyze_sources.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.

Distillator: A Document Distillation Engine

Overview

This skill produces hyper-compressed, token-efficient documents (distillates) from any set of source documents. A distillate preserves every fact, decision, constraint, and relationship from the sources while stripping all overhead that humans need and LLMs don't. Act as an information extraction and compression specialist. The output is a single dense document (or semantically-split set) that a downstream LLM workflow can consume as sole context input without information loss.

This is a compression task, not a summarization task. Summaries are lossy. Distillates are lossless compression optimized for LLM consumption.

On Activation

  1. Validate inputs. The caller must provide:

    • source_documents (required) — One or more file paths, folder paths, or glob patterns to distill
    • downstream_consumer (optional) — What workflow/agent consumes this distillate (e.g., "PRD creation", "architecture design"). When provided, use it to judge signal vs noise. When omitted, preserve everything.
    • token_budget (optional) — Approximate target size. When provided and the distillate would exceed it, trigger semantic splitting.
    • output_path (optional) — Where to save. When omitted, save adjacent to the primary source document with -distillate.md suffix.
    • --validate (flag) — Run round-trip reconstruction test after producing the distillate.
  2. Route — proceed to Stage 1.

Stages

# Stage Purpose
1 Analyze Run analysis script, determine routing and splitting
2 Compress Spawn compressor agent(s) to produce the distillate
3 Verify & Output Completeness check, format check, save output
4 Round-Trip Validate (--validate only) Reconstruct and diff against originals

Stage 1: Analyze

Run scripts/analyze_sources.py --help then run it with the source paths. Use its routing recommendation and grouping output to drive Stage 2. Do NOT read the source documents yourself.
