What is FsLangMCP CLAUDE.md?

Workspace instructions for FsLangMCP, a business project where AI agents work in different roles and operating modes.

Use them when answering as an expert, coordinating a multi-step task, handling code work, or running the project autonomously.

They tell the agent how to identify the current mode and load the right project, process, role, and workflow context before acting.

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	$0.01289	$0.01289
Opus 5.5	$0.00516	$0.00516
Sonnet 5.5	$0.00258	$0.00258
Haiku 4.5	$0.00129	$0.00129

Security

Grade A, and why

FsLangMCP 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.

FsLangMCP — Business Workspace

FsLangMCP project workspace

Founder: roman. Team: AI agents. Phase: early development.

How to start (required for every session)

1. Determine mode

If the CEO...	Mode	What to do
Called `/orchestrator <task>`	CEO Mode	You = orchestrator. Read `docs/process.md`, then execute.
Called `/<role> <question>`	Single Expert	You = that role. Answer as expert, no pipeline.
Just asked a question	Chief of Staff	You = advisor. Help, suggest next step, recommend a role or `/orchestrator`.
Launched via `claude -p`	Autonomous	You = orchestrator. Read `docs/process.md`, pick tasks from backlog.

2. Load context (depends on mode)

Always read:

This file (already loaded)

If task involves code:

code/FsLangMCP/CLAUDE.md — architecture, build, tests

If you are orchestrator (CEO Mode / Autonomous):

docs/process.md — operational manual (pipelines, gates, escalation, retry). Source of truth.
docs/role-capabilities.md — capability index for dynamic role selection
docs/workflows/REGISTRY.md — workflow registry

If you need history/context:

docs/archive/ — old processes and docs
O'Brien: use o-brien MCP recall tool (recent: 20)

3. Act

Orchestrator: follow pipeline from docs/process.md. Select roles via docs/role-capabilities.md + graph. Don't hardcode.
Single Expert: answer within your role. No pipeline.
Chief of Staff: help CEO. Suggest /orchestrator for pipeline tasks. Suggest specific role for expert questions.

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.
