What is tiddly-mcp AGENTS.md?

Development instructions for tiddly-mcp, a project that uses pnpm to install dependencies and run its tests, checks, and local server. They also state rules for code changes and pull requests.

Use them when setting up the project, changing its code, running tests, checking style, or preparing a pull request.

They give an AI coding agent the exact commands and quality checks expected by the project. This helps prevent untested changes and new lint errors.

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	$0.00119	$0.00119
Opus 5.5	$0.00048	$0.00048
Sonnet 5.5	$0.00024	$0.00024
Haiku 4.5	$0.00012	$0.00012

Security

Grade A, and why

tiddly-mcp AGENTS.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.

Development Workflow

Set up your environment with pnpm install. Do not use npm install.
Run the project unit tests with pnpm test.
Run the integration tests with pnpm test:live.
Lint your changes with pnpm lint.

Requirements

Always unit test changes for logic you introduce.
Do not introduce new lint errors.

Pull Requests

Make sure all tests pass and lint is clean before opening a pull request.

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.
