What taste-1 actually is — reading the command-code 1.58.0 npm bundle

A developer's teardown of the command-code CLI npm package version 1.58.0 shows that its advertised "taste-1" meta neuro-symbolic AI model is not a trained model at all: the tool shells out to git to collect up to 200 commits' worth of before/after diff pairs, compiles them into a markdown prompt, sends that as a single user message to the same /alpha/generate endpoint used by ordinary requests, and writes the model's markdown output to .commandcode/taste/taste.md, which is then pasted back into the system prompt on later turns. The analysis found no embeddings and no weight updates, contradicting the vendor's documentation claim of a continuously learning RL-powered model.

Full teardown, including every system prompt, the three sources taste feeds on, the tool catalogue, the wire protocol and the telemetry: https://gist.github.com/safzanpirani/26170636512c0b50494d6a70acfece8d https://gist.github.com/safzanpirani/26170636512c0b50494d6a70acfece8d Web version: https://cmd.safzan.dev https://cmd.safzan.dev Notes from reading the command-code npm package Command Code CLI , version 1.58.0 , 2026-09-19. Everything below is from the shipped bundle; line numbers are for dist/cli.mjs run through npx prettier --parser babel 115,067 lines . Reproduce with: npm i -g command-code@1.58.0 npx prettier --parser babel \ "$ npm root -g /command-code/dist/cli.mjs" cli.pretty.mjs No unpacking needed — it is a plain minified ESM bundle, and esbuild's --keep-names is on, so every function is wrapped in name fn, "originalName" and the original identifiers survive.

Send it to an ordinary model. That string becomes a single role:"user" message on a normal session, posted to the same /alpha/generate endpoint every other request uses, on whatever model is currently selected: js const o = await e.createSession { sessionId: …, baseUrl: t.getApiBaseUrl } ; o.setState { state: { …, messages: { role: "user", content: { type: "text", text: e.compiledContext } } } } ; await o.learn { outputDir: e.outputDir } ; 4.

Configure your own provider and the badge disappears while the feature behaves identically. It labels whichever model you picked claude-sonnet-4-6 , moonshotai/Kimi-K2.5 , … . It never names one. Grep the bundle for taste-1 and you get four hits: this line, the FAQ string, the help string, and the billing string below. There is no model id, no routing entry, no catalog record. From the plans help text :64749 : "Premium requests: Any request that uses a premium model like taste-1 during your coding session." Classifying taste-1 as a premium model is what justifies charging premium-request rates for taste operations. The model catalog in the same bundle lists ~80 real model ids DeepSeek, Kimi, GLM, MiniMax, Qwen, GPT, Claude, Grok, Gemini with contextWindow , reasoningEfforts and provider routing. taste-1 is not among them. The CLI states :64741 , :64749 : "Privacy: Taste processing runs on your codebase and stores learning data locally only." "Taste processing runs on your codebase and stores learning data in your project and on your local machine only." Storage is local — taste.md is written under .commandcode/taste/ . Processing is not. Step 3 above posts compiledContext to https://api.commandcode.ai , and that context embeds verbatim source lines . buildSnippet2 :55612 emits changed lines prefixed → with surrounding context lines indented two spaces: Snippet: <context line → <your changed line <context line Sending code to a model is what an inference call is, and is unremarkable in the main agent loop where the user knows it is happening. Taste is presented as local analysis. "Runs on your codebase … on your local machine only" reads as a claim that the code does not leave the machine, and it does. The bundle ships a sensitive-filename denylist :68900 : .env .env. .pem .key id rsa id rsa. id ed25519 id ed25519. id ecdsa id ecdsa. credentials credentials. .crt .npmrc .pypirc .netrc hasSensitiveBasename consumes it at six call sites — write-guarding :17640 , path-safety sets :17728 , :17773 , IDE/telemetry file lists :74588 , :74600 , :74606 . The taste extractor is not one of them. Its only filter is isNoiseFile :55556 , list at :77172 : package-lock.json pnpm-lock.yaml yarn.lock CHANGELOG. .versionbot/ .min.js .min.css dist/ .map That is a relevance filter, not a safety filter. Because taste reads history rather than the working tree, a repo that ever committed a .env , .pem , id rsa or credentials file will have those hunks extracted verbatim and uploaded with everything else — deleting the secret from HEAD does not remove it from the commit range taste mines. The filter exists and is applied in six places. It is missing from the one path that ships historical file contents off the machine. - Opt out of telemetry with DO NOT TRACK=1 or "telemetry": false in ~/.commandcode/config.json . - The taste feature is genuinely useful. An automated first pass at a conventions file, derived from what you actually did rather than what you'd claim you do, beats a blank CLAUDE.md . None of the above is an argument against using it. - The objection is narrow: the mechanism is prompt engineering, and it is described as a neuro-symbolic model with reinforcement learning. - All of this is from a published npm package, read as shipped. Version-pinned to 1.58.0; later releases may differ.
