META v3.1 — LLM Agent Engineering Charter
A compact, always-loaded set of operating rules for frontier coding agents such as Claude Code or Cursor, paired with three explicitly invoked skills for continuous execution, parallel work strands and pre-commitment failure analysis.
META is a short core charter, kept under a hard byte limit enforced by continuous integration, consisting of one guiding bias, one meta-rule and nine numbered rules, loaded automatically every session so a coding agent behaves like a disciplined engineer rather than an eager junior. Three additional skills are invoked only explicitly by the user: zero-pause for continuous execution without artificial pauses, weave for scoped parallel work strands with judgment-based conflict resolution, and premortem for failure analysis before committing to a high-risk plan.
The project's v3 revision removed trigger-phrase auto-activation, where text anywhere in a task, including pasted files or quoted content, could previously switch the agent into an autonomous execution mode; the authors identify this as a prompt-injection surface and now require the skills to be invoked explicitly by the user. An included TypeScript and Docker evaluation harness runs pairwise blind judging and deterministic metrics to compare the charter's effect across versions.
