What is Dragon-Brain CLAUDE.md?

A set of Claude Code instructions for Dragon Brain, a persistent memory layer for software projects. It defines how the coding assistant should use the memory system and apply project guardrails.

Use it to configure Claude Code for Dragon Brain projects, including memory handling, audit history, and the project's required working conventions.

It gives Claude Code project-specific context and rules instead of relying only on the current conversation or source files.

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	$0.06132	$0.06132
Opus 5.5	$0.02453	$0.02453
Sonnet 5.5	$0.01226	$0.01226
Haiku 4.5	$0.00613	$0.00613

Security

Grade A, and why

Dragon-Brain CLAUDE.md 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 2mo 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.

The Harness

Assertive pushback is non-negotiable. See global ~/.claude/CLAUDE.md § The Harness — 6 guardrails against yes-man behavior. Do NOT hedge-then-agree. Say NO first, make Tabish argue his case. Devil's advocate on every decision. Name the opportunity cost.

Audit Remediation (April–May 2026, Complete 2026-05-09)

4-phase adversarial audit found 83 contract violations across 37 source files. Fixes shipped in 10 batches B1–B10, all landed. Final state: violations 64 → 13 (~80% eliminated), remainder are documented legitimate fallback paths under quarterly review.

B10 — Async-Native Repository Migration (completed in 8 sub-batches B10.A through B10.epic-finalize):

AsyncMemoryRepository wrapper (asyncio.to_thread over FalkorDB sync client; ~75 call sites migrated across CrudMixin, SearchChannels, TemporalMixin, ValidationMixin, AnalysisMixin)
Cross-store compensation in crud.py for create/update/delete entity — Qdrant upsert failure rolls back FalkorDB write to prevent split-brain orphans
Integration test harness via testcontainers-python at tests/integration/test_db_kill_scenarios.py — 5 tests using real container.kill() to assert SearchError on infra outage
1230 unit tests pass under -W error, zero RuntimeWarning leakage
B10.5 (native async via falkordb.asyncio.FalkorDB) deferred as future epic — current asyncio.to_thread wrapper is a correct intermediate state; FalkorDB v1.4.0 ships native async support, future epic will swap the wrapper out
B10.F entity-level lock granularity deliberately deferred to a future epic — project-level locks remain in place, appropriate for current scale

The lie this audit closed

Before B1: search() wrapped its entire pipeline in except Exception: return []. The MCP search_memory tool transformed that into "No results found." — a confident string lie indistinguishable from "I genuinely have no memories on this topic." Every degraded memory query was Claude operating on missing context without knowing it. For two months, Dragon Brain was potentially lying to Claude on every infrastructure failure.

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.
