SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill solves the problem of getting inaccurate, generic answers from training data when asking about the Lossless Group's prior work, decisions, shipped features, and past issues. Without it, you would rely on stale or unverified information instead of the team's actual, citable internal records.

Core Features & Use Cases

  • Multi-Collection Search: Queries four curated Chroma collections (context-vigilance-corpus, lossless-changelog, claude-code-sessions, claude-code-tool-traces) to cover decisions, shipping history, past sessions, and tool failures.
  • Structured Search Loop: Uses a 4-step agentic workflow (decompose → execute → evaluate → synthesize) with a 5-query budget to find precise answers efficiently without wasting resources.
  • Citation Discipline: Every claim is tied to a verifiable source path, timestamp, or repo slug, so you can confirm the answer in seconds.
  • Use Case: If you ask "why did we choose PersistentClient for Chroma?", the skill pulls the exact decision from past Claude Code sessions, cites the source document, and lets you verify the context in seconds.

Quick Start

Use the search-lossless-corpus skill to find out why we chose PersistentClient for our local Chroma setup and when that decision was made.

FAQPage Schema
How do I search internal decision history and past Claude Code sessions for prior work context?

To search internal decision history and past Claude Code sessions, use a structured corpus search across dedicated Chroma collections. This retrieves verifiable answers with source citations from records like changelogs and tool traces, avoiding stale training data.

Can I retrieve the exact reason for a past architectural decision from a local Chroma database?

Yes, you can retrieve exact architectural decisions from a local Chroma database. The search queries internal session records and enforces source citations for every claim, allowing you to verify the original context, timestamps, and repo slug in seconds.

What is the best way to find specific shipped features and recurring tool failures in past development cycles?

The best way to find shipped features and recurring tool failures is querying curated internal changelog and tool trace collections. This method applies a multi-collection search with a strict query budget to extract precise, verified answers from actual development records.

Does corpus search enforce a limit on database queries per question?

Yes, corpus search enforces a strict 5-query budget per question. This structured search loop limits resource waste by decomposing, executing, evaluating, and synthesizing queries efficiently against the Chroma database.

How does agent knowledge retrieval ensure answers are verifiable and not hallucinated?

Agent knowledge retrieval ensures verifiability by mandating source citations for all synthesized claims. Every extracted answer is tied to a verifiable source path, timestamp, or repo slug from internal records rather than relying on generated training data.

When do I need to search a lossless corpus instead of asking about prior work directly?

You need to search a lossless corpus when querying specific past team decisions, shipping timelines, or internal conventions that require verifiable proof. It replaces generic, unverified training data responses with citable records from actual development sessions.
