bearing CLAUDE.md

bearing CLAUDE.md is an instructions file for coding agents from rocketvish/bearing. It costs 1,435 tokens per session, scanned A, a copy of bearing AGENTS.md, MIT.

Project instructions for Bearing, a command-line task orchestrator that runs coding agents and manages their context across tasks.

In plain words
What is it for?
Use them when changing Bearing's orchestration loop, prompt assembly, task queue, status reporting, context tools, or evaluation framework.
Why use it?
They explain the repository structure, supported agent providers, context handling, history compression, retrieval, and evaluation setup.

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

bearing CLAUDE.md scanned grade A with 1 finding 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 5d 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.

Bearing - Task Orchestrator for CLI Agents

Architecture

  • bearing.py -- CLI entry point + orchestration loop (run_orchestrator, propagate_context)
  • executor.py -- Prompt assembly (assemble_prompt) + CLI execution (run_task)
  • relevance.py -- Embedding-based relevance scoring + compression via Ollama
  • eval_runner.py -- Evaluation framework: runs benchmark under 4 context format conditions
  • eval_compare.py -- Eval compare: Bearing (8 sessions) vs single session (1 mega-prompt)
  • agent.py -- Tool-use agent via provider adapters (OpenAI Responses or Anthropic Messages, urllib/no SDK), with prompt caching + reasoning effort
  • compressor.py -- Mid-conversation history compression (API or Ollama backends)
  • retriever.py -- Embedding-based selective history retrieval via Ollama (nomic-embed-text)
  • eval_agent.py -- Eval: agent with/without compression/caching/retrieval vs claude -p (7 conditions)
  • test_sanity.py -- Quick sanity test for caching + reasoning features
  • tasks_schema.py -- Dataclasses for Task, TaskQueue, TaskResult
  • status_writer.py -- Generates status.md from task queue state

Eval Framework

Four context format conditions: prose, structured, embedding, embedding+llm.

Eval Compare (bearing eval-compare)

Compares Bearing's 8-session approach against a single mega-prompt session. This tests the core value proposition: task isolation prevents context accumulation and compaction. The single session gets the same task prompts and FOCUS directives but must build everything in one accumulated context. Key metrics: total tokens, compaction count, per-task quality.

Key Learnings

Embedding similarity baseline is high for same-domain text. nomic-embed-text cosine similarity for chunks within the same project bottoms out around 0.5-0.6, not 0.2-0.3. Default thresholds are set at keep=0.75, drop=0.55 to account for this. Benchmarks that need chunks to actually drop require genuinely unrelated domains (e.g., different languages or problem spaces), not just "parallel feature tracks" in the same codebase.

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.
