fusebase-flow: Instructions file for Claude Code

CLAUDE.md

fusebase-flow CLAUDE.md is an instructions file for Claude Code from fusebase-dev/fusebase-flow. It costs 506 tokens per session, scanned A, original, MIT.

A Claude Code adapter for Fusebase Flow, a workflow layer that adds lifecycle and role guidance to coding-agent work. It lists the documents, skills, role references, workflows, and maintenance guidance Claude must read.

In plain words
What is it for?
Use it to start Claude sessions with the required project rules, load the active workflow and handoff, follow role and state requirements, and locate the project's mirrored skills, agents, and commands.
Why use it?
It prevents Claude from treating short skill descriptions as full instructions and helps keep the same workflow contract across different agent interfaces.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is fusebase-dev/fusebase-flow's own configuration. It tells Claude Code how to work on fusebase-flow itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything fusebase-flow configures →

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

fusebase-flow 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 6d 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 — Claude Code adapter for Fusebase Flow

This repo runs Fusebase Flow v5.11. Read AGENTS.md (unless its Flow overlay section is already in context), FLOW_RULES.md through ## Amendment log, both mandatory skill bodies, flow-skills/role-discipline/references/<role>.md, and the active workflow/ticket artifacts. Canonical provider details are in the recovery-owned adapter below.

For maintenance work in this repository, also read docs/maintainer-execution.md. It is not copied into consumers.


FuseBase Flow — Claude Code adapter

Read AGENTS.md unless its FuseBase Flow — workflow lifecycle overlay section is already in context, then FLOW_RULES.md through ## Amendment log. Claude Code supplies skill descriptions/metadata, not skill bodies. Read flow-skills/communication/SKILL.md, flow-skills/role-discipline/SKILL.md, and the attested role's reference once unless each exact body is already in context. Read the active workflow and ticket/handoff. Use the attestation and state footer from FLOW_RULES.md.

Claude surface Canonical owner
lifecycle skills flow-skills/ mirrored to .claude/skills/

commands (/fusebase-health, /onboard, /product-owner, /handoff, /token-waste-audit, /find-wasted-effort, /find-wasted-code, /step-out) hooks/local/fusebase-flow-overlays/commands/ mirrored to .claude/commands/

Hooks are opt-in until .claude/settings.json.example is merged into .claude/settings.json; Git hooks remain the fallback. Existing Fusebase CLI runtime/MCP/SDK rules override generic Flow guidance; Flow owns the lifecycle. For active context, commands, install/update recovery, and mixed-fleet behavior, use AGENTS.md; do not reprint those procedures here.

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.
