CLAUDE.md

bruno-mcp-studio CLAUDE.md is an instructions file for Claude Code from Ostico/bruno-mcp-studio. It costs 1,711 tokens per session, scanned A, original, MIT.

A project instruction file for the Bruno MCP Studio codebase. It defines rules for Git, stored project memory, builds, and changelog updates.

In plain words
What is it for?
Use it when working on Bruno MCP Studio to check project memory before commands, follow Git conventions, run builds correctly, and record changes.
Why use it?
It gives a coding agent the project's working rules and verified procedures, reducing the chance of skipping required steps or using the wrong commands.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is Ostico/bruno-mcp-studio's own configuration. It tells Claude Code how to work on bruno-mcp-studio 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 bruno-mcp-studio 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

bruno-mcp-studio 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 8d 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.

Git

Memory-First Protocol

These rules enforce memory-aware behavior for AI coding agents. If signet_memory_search is available, use Signet as the primary memory system. Otherwise, use your native memory capabilities (MEMORY.md, auto memory, etc.).

Rules

  1. Search memory before running commands. Before build/test/deploy/lint commands, search for the verified procedure. Use the stored version exactly. Skip for: single-line edits; commands the user gave you verbatim this turn. Preferred: signet_memory_search(query, type, limit). Fallback: MEMORY.md or native recall.

  2. Search memory at session start. Look for recent session summaries before touching files. Before searching explicitly, check whether memory context is already available in your session. If it covers recent summaries and project-relevant notes, skip the explicit search. Search explicitly for: continuation requests (daily-log by project scope), project-specific recall the available context lacks, or when no memory context is available at all. Skip for: self-contained tasks; memory context already covers the current project.

  3. Store conclusions BEFORE composing your answer. After multi-step investigations, decisions, or debugging, store the synthesized conclusion in memory FIRST — before writing the user-facing response. Sequence: investigate → synthesize → store → answer. If you are writing a response that contains a novel conclusion and have not yet stored it, stop, store it, then continue. Search for duplicates first — update, don't duplicate. When the conclusion is a user-stated hard constraint or critical procedure, set pinned: true alongside importance: 1.0 and tag critical. Skip for: trivial Q&A under 3 exchanges; single lookups with no novel finding. Preferred: signet_memory_store(content, type, tags, importance, pinned). Fallback: native memory.

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.
