Last week’s post ended on a one-line joke: Further work: Add Tamarian mode. Four hours later it was a plugin. This is what it does, why it is the same argument as Design Patterns Are Darmok with the sound turned on, and the one rule it forced on our skills catalog.

What it does

/tamarian full, and from that reply on, Claude Code answers as the Children of Tama, the aliens from the Star Trek episode Darmok whose language is nothing but pointers to shared stories. Ask why the build fails:

Shaka, when the walls fell - the build fails. Hopper, the moth in the
relay - `user` may be `undefined` at `auth.ts:42`. Temba, his arms wide -
    if (!user) return null;

Every beat of prose is a metaphor, a dash, and the literal statement. The metaphor names the situation; the gloss carries every fact. Nothing technical is lost to the poetry, which is the whole design and the only part that took any thought.

The compression, made audible

The Darmok post’s claim was that a design pattern name is a compressed story. “Singleton” is a paragraph of situation crushed to a token, and it only decompresses if the reader holds the dictionary. The token is the payoff; the paragraph is the price.

Tamarian mode is that claim turned into a user interface. In full, you pay the price on every line: name, then paragraph, in that order, so you can hear the codec run. In lite the metaphor is one line of garnish and the rest is plain speech. In ultra the prose is pure metaphor and every paragraph is deferred to a glossary at the end, titled The river Temarc. Which is to say: ultra is what the Gang of Four refused to write. They wrote a book, not a glossary, because the naming and the teaching are the same act. ultra is the glossary. It is exactly as much fun, and exactly as useful, as the earlier post predicted.

Coining rules are catalog rules

The Children of Tama never saw a stack trace, but Earth knows Sisyphus, so the phrasebook is where the plugin gets its range: twenty canon phrases from the episode and some sixty coined from myth, history and the craft. Hopper, the moth in the relay is a bug, found. Cassandra at the gates is the warning ignored: the deprecation notice, the log line nobody read. Chesterton, his hand on the gate: understand the fence before removing it. Mars Orbiter, feet and meters is the unit mismatch, and left-pad, withdrawn is the tiny dependency whose absence breaks the world.

The rules for coining a new one are the interesting part, because I wrote them as rules for a persona and read them back as rules for a pattern catalog:

1. The figure must be recognizable from shared culture. Obscurity is not depth.
2. A phrase is reusable, not a one-off simile. If it cannot serve twice, it is not a phrase.
3. The same meaning takes the same phrase for the whole session. A session lexicon grows.
4. The first use of any coined phrase carries its gloss.

Swap “phrase” for “pattern” and “session” for “team” and that is the entry criteria for a shared skills library. Rule 2 is why “own the merge” earned a name and most of what gets said in standup does not. Rule 4 is the Darmok rule from the earlier post, now enforced by a hook.

The floor

Some things never become metaphor, at any level: code, commands, file paths, identifiers, URLs, versions, quantities, and error text, quoted exact. auth.ts:42 stays auth.ts:42; it is never “the forty-second stone of the gate of Auth.” And some situations drop the voice entirely, mid-reply: security findings, confirmations of destructive or irreversible actions, step sequences the user must execute, and the moment the user looks confused. Then it translates, plainly, and resumes.

That floor is the Darmok warning applied as a safety rule. A pattern name handed to someone who never learned it is noise in a confident voice. A DROP TABLE confirmation in a confident voice the reader has not decoded is worse than noise. So the plugin’s one hard boundary is that the joke never gets to stand between the user and the consequence.

Mechanics, and the rule it forced

The mode machinery is borrowed, with thanks, from caveman, the terse-mode plugin. A level (lite, full, ultra) persists in ~/.claude/.tamarian-mode. A SessionStart hook reads that file and, if a level is set, emits the skill body into the session at runtime: one source of truth, no duplicated prompt. A UserPromptSubmit hook adds a one-line reminder on every prompt, so the voice survives long conversations and context compression. Two bash scripts, no dependencies, both print OK when the mode is off; installing the plugin changes nothing until you invoke it.

/plugin marketplace update skillz
/plugin install tamarian@skillz
/tamarian full

Caveman and Tamarian are the same knob turned opposite ways. Caveman’s README claims about 75% fewer tokens by stripping a sentence down to its referent. Tamarian names the referent and then insists on the sentence anyway. One is a token saver; the other is a demonstration, and says so in its own description: purely for entertainment.

The rule it forced: voitta-ai/skillz ships one big skillz bundle plugin plus standalone plugins, and until today a standalone plugin’s skill was also symlinked into the bundle. For a hooked plugin that is a bug. The bundle manifest carries no hooks, so the bundle copy of tamarian would speak Tamarian for one session and then forget, the dictionary lost at session end. Worse, installing both exposed the same skill twice, /skillz:tamarian next to /tamarian:tamarian. New rule, in #233: a skill that ships inside a hooked plugin is not in the bundle, and the catalog validator detects hooks from the manifests themselves, so a plugin that grows hooks later trips the check with no flag to forget. Three plugins moved out under it.

The conclusion, in ultra

The session that drafted this post ran /tamarian full. The conclusion below it wrote in ultra, glossary included, and I leave it as it came.

Darmok and Jalad at Tanagra: the last post and this one. Kira at Bashi, a joke in the final line. Mirab, with sails unfurled, four hours on. Sokath, his eyes uncovered: the pattern name is the token, the paragraph its price, and full pays it aloud on every line. Odysseus, lashed to the mast: auth.ts:42 is never a stone in a gate, and DROP TABLE is never a verse. Chesterton, his hand on the gate: the bundle copy, and the rule it forced at #233. Caveman and Tamarian at the same fork, facing opposite ways. Picard and Dathon at El-Adrel.
