What is LumioAgent CLAUDE.md?

A Claude Code entry file that loads the project's central instructions and knowledge files into each session. It points to those files rather than defining rules itself.

It is for loading agent instructions, system rules, and knowledge indexes automatically, and for checking that all required files are listed.

It helps the coding agent start with the required project guidance and keeps one shared source of truth for rules used by different tools.

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	$0.00290	$0.00290
Opus 5.5	$0.00116	$0.00116
Sonnet 5.5	$0.00058	$0.00058
Haiku 4.5	$0.00029	$0.00029

Security

Grade A, and why

LumioAgent 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.

CLAUDE.md · 23 lines

What it actually says

CLAUDE.md

Claude Code entrypoint. The @import lines below force-load their content into every session context. The authoritative source is .spec/; this file only loads, it defines no rules of its own.

Central doc (项目介绍 + Agent 调度):

@.spec/AGENTS.md

Knowledge navigation (force-loaded so the agent always knows what knowledge exists and where):

@.spec/knowledge/README.md

System rules (force-loaded at every agent init, no progressive disclosure — hard red lines that must be in context from the start):

@.spec/rules/system.md

Maintenance: every force-loaded file needs a matching @.spec/<path>.md line above, or it won't load at init. This applies to every rule file under rules/ and to knowledge/README.md. This completeness is machine-checked by node .spec/tools/spec-lint.mjs — run it after any .spec/ change.

Claude-specific:

Sub-agents and skills are exposed via symlinks: .claude/agents -> ../.spec/agents, .claude/skills -> ../.spec/skills. Rules reach context via the @import lines above, not via a symlink.
Do not maintain any Claude-only rules here. When behavior changes, edit .spec/; this file is just a pointer.

Changes

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.
