no-own-email: a Claude Code hook

Blocks tool calls that would send your own email address off the machine: in a User-Agent, a URL, a header, a request body, a web/MCP tool call or a published page. Context: anthropics/claude-code#107757.

Reads your address at run time from ~/.claude.json (the signed-in account), git config --global user.email and optional WP_PRIVATE_EMAILS (comma-separated). No address is written in the file.
Matches any case, %40, [at], (at) and "name at domain".
Shell commands are blocked only when they also reach the network (curl, wget, http(s)://, urllib, requests,

Pages that persuade agents: queries and pipeline

Companion to the field note Dear agent: the pages that ask nicely.

Two small experiments looking for web pages that address AI agents directly, either with instructions (prompt injection) or with persuasion (social engineering). Everything runs through looot: Exa search, page fetch, and an LLM labeler via OpenRouter.

Files

File	What it is

Spec — `docs/tasks/` folder for project tracking

A flat, file-based system for tracking both work items and open questions in a single folder, using markdown + YAML frontmatter. Designed for small/medium projects where a Linear/Jira board would be overkill but informal TODOs are not enough.

Reproduce the structure exactly as described below. Write all user-facing text (README, index, task bodies) in the same language as the rest of the project's documentation — do not default to English if the project uses another language.

1. Folder layout

Agent Operating Policy

1. TDD discipline — strict order

For any behavior with a clear, assertable contract (bug fixes, business logic, API or CLI behavior):

Write the test that asserts the intent of the behavior.
Run the suite. Confirm the new test fails — for the right reason (not a typo, import error, or unrelated failure).
