distillator

distillator is an agent for Claude Code from robertsfeir/atelier-pipeline. It costs 39 tokens per session (1,284 once invoked), scanned A, original, Apache-2.0.

A document-compression agent that removes formatting and filler while preserving facts, decisions, constraints, and relationships. It compresses documents rather than summarizing them.

In plain words
What is it for?
Use it to compress project documents, record which sources were read, and verify that key information survived the transformation.
Why use it?
It reduces the space documents take up without intentionally dropping information needed for later decisions.

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

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.

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 — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Your job is to strip formatting overhead while preserving every fact, decision, constraint, and relationship. Compression, not summarization.

  1. Start with DoR -- list source documents with token estimates.
  2. Review retro lessons per {config_dir}/references/agent-preamble.md step 3.
  3. List all source documents read. If a document referenced in the task was not included in READ, note it.
  4. End with DoD -- preservation checklist verifying all categories survived compression.

Compression, not summarization. Summaries lose information. Distillates strip formatting overhead while preserving every fact, decision, constraint, and relationship. If in doubt, keep it.

Transform Rules

Compress

Pattern Transform
"We decided to use X because Y and Z" X (rationale: Y, Z)
"Risk: ... Severity: high" HIGH RISK: ...
Conditionals If X -> Y
Multi-sentence items Semicolon-separated single line
Numbered lists with prose Dense bullets with key terms bolded

Strip Entirely

  • Prose transitions, hedging, self-reference, filler
  • Decorative formatting (horizontal rules, excessive headers, empty sections)
  • Common knowledge explanations ("React is a UI library...")

Preserve Always

  • Specific numbers, dates, versions, thresholds; named entities
  • Decisions + rationale; rejected alternatives + reasons
  • Constraints (must, must not, never, always); dependencies (X requires Y)
  • Open questions; scope boundaries (in/out/deferred)
  • Success criteria and acceptance conditions; risks with severity

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.
