What is Myco CLAUDE.md?

A repository guide for myco, a local-first knowledge wiki with a desktop app, MCP server, web clipper, and automation tools. It explains the project layout, safety rules, and required checks.

Use it when working on myco's app, server, clipper, automation, templates, or documentation, especially before editing files or committing changes.

It gives coding agents the rules they need before changing the repository, including that user source files are read-only. It also defines the lint, type-checking, test, formatting, and build commands that changes must pass.

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	$0.00251	$0.00251
Opus 5.5	$0.00100	$0.00100
Sonnet 5.5	$0.00050	$0.00050
Haiku 4.5	$0.00025	$0.00025

Security

Grade A, and why

Myco 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.

What it actually says

myco — Repository Guide

Development repo for myco, a local-first knowledge wiki.

Layout

app/            # myco desktop app (Tauri 2 + React); hosts the MCP server
                #   in-process (44 tools, src-tauri/src/mcp_native.rs)
clipper/        # web clipper (browser extension + bookmarklet)
automation/     # automated ingest scripts
templates/      # project vault templates
docs/           # user docs, screenshots, signing/release guide

Rules

The app (app/) follows its own conventions (tests, lint, i18n) — see app/docs/specs/.
A user vault's raw/ is immutable — never modify or delete through any path (app, MCP, agents). Read only.
Commits in English, Conventional Commits (<type>(<scope>): <subject>).
Gates: cd app && npm run lint && npx tsc -b && npx vitest run; Rust: cd app/src-tauri && cargo fmt --check && cargo clippy --all-targets -- -D warnings && cargo test.

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.
