From beea528423a3102098141b76c64116b704f15875 Mon Sep 17 00:00:00 2001 From: Ricardo Vega Date: Wed, 30 Sep 2026 06:49:36 -0500 Subject: [PATCH] Slice 6: compile recorded traces into recipes with `tyto compile`. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - core: COMPILER_CARD (the prototype's proven rules, adapted: params read inside eval, origins/domains, typed params, structural verify, page-signalled ambiguity, count items not siblings, self-test on at least 3 inputs), compilerPrompt (task and kept params outside a random-nonce fence, every page-derived step and output inside it), extractRecipeJson, checkCompiled (parse + lint + origins must be ones the trace visited; always stored as a draft), compileTrace, and a Compiler port with a fake. - @tyto/compiler: ClaudeCodeCompiler runs `claude -p` in a private work folder with ANTHROPIC_API_KEY removed, only Bash(tyto compile-tool:*) allowed, Write/Edit/Web/Task denied, and a tyto shim on PATH. - cli: `tyto compile `, `tyto compile-tool draft|test|ab` (only inside a compile; ab runs in a no-login, domain-restricted session with content boundaries), and `tyto recipes approve [--yes]`. Verified live: a Wikipedia status task recorded once and compiled once (94 s) answered 6/6 species correctly with no model in 0.26–0.31 s warm. Claude Code refused a chained `tyto compile-tool … && touch …` outright. The opt-in live compiler test (TYTO_LIVE_COMPILER=1) passes.
