From c56b0297dfe94be5cf8aabbc1e0feaa37b02c8e6 Mon Sep 17 00:00:00 2001 From: vinayada1 Date: Thu, 20 Aug 2026 10:58:23 -0700 Subject: [PATCH] refactor: centralize AI assessment prompts in an embedded prompt file Move every AI grading rubric out of Go constants scattered across step packages and into a single embedded prompt file, so the prompts can be read, reviewed, and diffed in one place instead of being reconstructed from three packages. The prompt text sent to the model is unchanged. Every existing golden file under the step packages' testdata directories is untouched by this commit, and the assembled prompts still match them byte for byte, so the equivalence claim is mechanically checked rather than asserted. Key the file by the behavior each rubric assesses rather than by the requirement it satisfies. Binding requirement IDs to logic is the dispatch map's job (see #448), and a rubric asking "are workflow permissions least-privilege?" is not the property of one catalog entry, so keying it by behavior lets a second catalog reuse the prompt instead of copying it under another ID and letting the two drift. Which requirement each behavior serves is asserted in the contract test rather than compiled into the step packages, so this adds no catalog-ID coupling outside the dispatch layer. Only the prompt-injection guard is shared. It is appended last, adjacent to the untrusted material, preserving the arrangement #452 (4626c87) deliberately introduced when it moved that paragraph out of the preamble. Sharing it means an assessment cannot ship without the guard. Everything else stays per-assessment, so a rubric reads in the prompt file exactly as the model receives it and a reviewer never has to assemble a prompt mentally to see what changed. The step tests now compare the prompt the step actually sent against the golden file rather than against the prompt file's own output, so they cannot pass by agreeing with a mistake in the assembly code. Mutating a rubric fails them until the golden is regenerated, which keeps the exact text sent to the model visible in the pull request diff. A companion test asserts every entry is pinned by some golden, so an assessment added later cannot ship with its prompt text unreviewed. Keep the loader itself minimal: it unmarshals and rejects unknown fields, so a misspelled key fails loudly instead of yielding an empty rubric. The file ships inside the binary with no override path, so the only way to break it is to edit it in a pull request, where the convention tests, the behavior-to-requirement contract test, and the step golden tests already fail by name on a bad key, missing instructions, or a repeated guard. Cover the conventions the rubrics rely on across every entry rather than a fixed list, so an assessment added later inherits the same checks: each prompt names its evidence set, marks it untrusted, states pass and fail criteria before the residual needs_review verdict, and does not offer needs_review for incomplete evidence, which would compete with rubrics that fail an assessment precisely when documentation is missing or partial. Deterministic checks still decide conclusive cases without calling AI, and every existing fallback still returns the same manual-review outcome.
