PirateBao

PirateBao be a Bun-first, TypeScript-first pirate rig for terse AI coding replies. Commands, code, paths, versions, risk notes, stack traces, and test results stay nailed to the mast. Greeting foam, hedge fog, and apology barnacles get keelhauled on sight. Kraken eats boilerplate; cargo stays lashed. Parrot squawks; token bill shrinks.

Default sail: kraken. Main flags: /piratebao, $piratebao, /piratebao:compress. Goal: fewer tokens, same technical cargo, less polite sea-tax.

Explain Like I'm 5

AI answers spend doubloons on hello, read the map thrice, then polish the plank until the plank demands equity. PirateBao heaves chatter overboard and lashes treasure to the mast: command, file, bug, fix.

Before	After
"Sure, I would be happy to help. The issue is likely caused by a new object reference on each render."	"New object ref each render. Use useMemo."

Same treasure map. Smaller scroll. Faster ship. Fewer invoices dressed as parrots. No "hope this helps" barnacle unless it actually fixes the failing test. Politeness is ballast; the kraken knows what to eat.

What It Ships

Area	Contract
Runtime	Claude Code hooks compile to dist/hooks/*.js; session start hauls no tsx anchor.
Skills	Canonical behavior lives in skills/piratebao/SKILL.md; copies synced and verified — drift walks the plank.
Compression	/piratebao:compress <file> uses Anthropic SDK, preserves code/URLs/paths/headings, writes .original.md backup.
OpenCode	Native .opencode/skills/<name>/SKILL.md and .opencode/commands/*.md; no plugin dependency in this pass.
npmjs	package.json exports compiled TypeScript cargo and gates the payload with npm pack --dry-run --json. No imaginary barrels aboard.
.bao	bao/piratebao.manifest.json is a cargo ledger, not an archive format. The quartermaster checks it.

What It Does Not Ship

Not aboard	Reason
Legacy aliases	Break rename is intentional. Old names are barnacles — scrape them.
CLI fallback for compression	Missing ANTHROPIC_API_KEY fails directly. Ghost oars cost maintenance and sometimes row toward prod.
.bao archive builder	This pass counts barrels and checks labels only. No archive builder lurks below deck.
Runtime TypeScript loader for hooks	Hooks run compiled JS. Ship does not stop to compile at dawn.

PirateBao

PirateBao は Bun-first / TypeScript-first の海賊リグです。AI コーディング返答から挨拶の泡、遠慮の霧、謝罪のフジツボを斬り捨てます。コード、コマンド、パス、バージョン、危険、スタックトレース、テスト結果はマストに釘打ちます。クラーケンは boilerplate を食べ、TypeError は残します。オウムは騒ぐ。token は金貨。礼儀に銀貨を払う船長はおらぬ。

5歳向け説明

AI は宝箱の前で長々と挨拶し、地図を三度読み直し、甲板を磨いて磨いて磨きがちです。PirateBao は泡を海に捨て、宝だけマストに残します: コマンド、ファイル、バグ、修正。金貨で霧を買わぬ。海賊は礼儀に銀を払わぬ。

PirateBao

PirateBao isch es Bun-first, TypeScript-first Pirat-Rigg für churzi AI-Coding-Antworte. Code, Befehle, Pfäd, Versione, Risiko, Stacktraces und Testresultat bliibe am Mascht feschtgnaglet. Begrüessigs-Schaum, Hättegli-Nebel und Entschuldigungsmuschele gönd über Bord — kielholt ohni Gnade. De Chrottekrake frisst Boilerplate, nöd Fehlermeldige. De Papagei chiflet; d token-Rechnig schrumpft. Höflichkeit isch Ballascht.

Für Chind erklärt

AI redt mängisch hoi, list d Charte drüümal und poliert s Brett bis es nach Büro riecht. PirateBao seit: Ladig bhalte, Blabla ab is Wasser. Tokens sind Münze; mir zahled nöd für Nebel mit Schnauz. De Hafemeister nickt; de Papagei chrächzt.

Install

Bun is the package manager of record. npm is used only where npmjs itself is the thing being tested, because even pirates respect the harbor office and its tiny clipboard of pain.

Harbor	Command	Checks
Install deps	bun install --frozen-lockfile	Uses bun.lock; fails if package.json drifted.
Build	bun run build	Emits dist/ JS, declarations, and source maps.
Test	bun run test	Builds, packs piratebao.skill, runs Vitest.
Verify all	bun run verify	Sync, .bao, OpenCode, stale-name scan, npm registry, npm pack dry-run.
Complete gate	bun run check	Typecheck, build, tests, verify, registry, pack dry-run.
Post-publish bunx smoke	bunx -p piratebao piratebao-verify	Runs the npmjs binary from Bun's package runner after the crate exists in the registry.

Agent installs:

Agent	Install
Claude Code	claude plugin marketplace add d4551/piratebao && claude plugin install piratebao@piratebao
Codex	Clone repo, open Codex, install local plugins/piratebao
OpenCode	Clone repo; OpenCode reads .opencode/skills/*/SKILL.md and .opencode/commands/*.md
Gemini CLI	gemini extensions install https://github.com/d4551/piratebao
Cursor/Windsurf/Cline/Copilot	npx skills add d4551/piratebao

Standalone Claude Code hooks:

bun install --frozen-lockfile
bun run build
bash hooks/install.sh

Uninstall:

bash hooks/uninstall.sh

/piratebao	default kraken mode
/piratebao skiff	light terse prose
/piratebao brig	strong terse prose
/piratebao kraken	maximum terse prose
/piratebao jade-skiff	light classical Chinese terse mode
/piratebao jade-brig	strong classical Chinese terse mode

$piratebao	Codex skill trigger

Deactivate with stop PirateBao or normal mode.

Mode Matrix

Family	Modes	Output contract
English	skiff, brig, kraken	shorter prose, same technical payload, stricter ceiling as sail gets heavier
Classical Chinese	jade-skiff, jade-brig, jade-kraken	terse classical Chinese phrasing, examples gated by token monotonicity
Japanese	nihon-skiff, nihon-brig, nihon-kraken	Japanese terse mode with the same no-filler/no-self-reference rules
Swiss German	swiss-skiff, swiss-brig, swiss-kraken	Swiss German terse mode with the same compression ceilings

All families forbid self-announcements like mode banners unless the user explicitly asks. PirateBao steers the ship; it does not give a speech from the crow's nest. The best compression is the sentence never emitted. The second best is the sentence that lost its adjectives at sea.

Runtime Flow

flowchart TD
  Prompt["agent prompt"] --> Hook["readCaptainOrder"]
  Hook --> Flag["~/.claude/.piratebao-active"]
  Session["session start"] --> Raise["raiseJollyRoger"]
  Raise --> Skill["skills/piratebao/SKILL.md"]
  Skill --> Filter["mode-specific rule filter"]
  Filter --> Agent["agent context"]
  Flag --> Status["paintStatusFlag"]

SessionStart loads the compiled hook and canonical skill once per invocation. UserPromptSubmit updates the mode flag. Statusline reads the flag and prints a small badge. This keeps startup work bounded; the ship does not inspect every barrel on each wave or bill you for barnacle inventory.

Shipyard Flow

flowchart TD
  Skill["skills/piratebao/SKILL.md"] --> Sync["syncTreasureMap"]
  Sync --> Copies["OpenCode/Cursor/Windsurf/Copilot/plugin copies"]
  Skill --> Pack["packSkillCargo"]
  Pack --> Zip["piratebao.skill"]
  Schema["schemas/piratebao-bao-manifest.schema.json"] --> Gate["verifyHarbor"]
  Manifest["bao/piratebao.manifest.json"] --> Gate
  Copies --> Gate
  Zip --> Gate
  Gate --> Release["npmjs-ready package"]

Canonical files are edited once, then synced. verifyHarbor rejects copy drift, stale brand tokens, missing OpenCode cargo, malformed plugin manifests, missing compiled artifacts, wrong zip contents, and README drift. The quartermaster is boring on purpose; comedy belongs in prose, not package invariants. The gate has no sense of humor and no parrot.

End-to-End Gate

Use this before publishing or after touching docs, skills, hooks, manifests, or compression logic:

bun install --frozen-lockfile
bun run typecheck
bun run build
bun run test
bun run verify
bun run pack:dry

Runtime smoke for standalone Claude Code hooks:

tmp_home="$(mktemp -d)"
HOME="$tmp_home" bash hooks/install.sh --force
HOME="$tmp_home" node "$tmp_home/.claude/hooks/piratebao-dist/hooks/raiseJollyRoger.js"
printf '{"prompt":"/piratebao swiss-kraken"}' | HOME="$tmp_home" node "$tmp_home/.claude/hooks/piratebao-dist/hooks/readCaptainOrder.js"
cat "$tmp_home/.claude/.piratebao-active"
HOME="$tmp_home" bash hooks/uninstall.sh
rm -rf "$tmp_home"

Expected smoke result: install succeeds, session hook emits PirateBao rules, prompt hook writes swiss-kraken, uninstall removes hook cargo. No bottle note required.

OpenCode Native Support

OpenCode support is project-native:

File	Purpose
opencode.json	Points OpenCode at AGENTS.md and allows piratebao* skills.
.opencode/skills/piratebao/SKILL.md	Synced main skill.
.opencode/skills/piratebao-compress/SKILL.md	Synced compressor skill.
.opencode/commands/piratebao.md	/piratebao command template.
.opencode/commands/piratebao-compress.md	Platform-safe /piratebao-compress; uses $ARGUMENTS.

Command filenames avoid : for cross-platform safety. Frontmatter descriptions are verified. This is not a TypeScript OpenCode plugin; no extra runtime hook hides in the bilge wearing a false moustache.

TypeScript Rig

Pinned current stack, verified on 2026-04-12:

Tool	Version	Role
Bun	1.3.12	install/scripts; lockfile authority
TypeScript	6.0.2	strict compile for src/ and tests
Node	>=24.11.0	runtime target for compiled hooks/CLIs
Vitest	4.1.4	behavior tests
AJV	8.18.0	.bao schema validation
Anthropic SDK	0.88.0	compressor API client
js-tiktoken	1.0.21	token evals

No direct env reads outside config modules. No any in implementation/tests. No TypeScript suppressions. If the mast cracks, the compiler gets first complaint, not a postmortem parrot. Types are the rigging; if they fray, the sail falls before the wind arrives.

.bao Contract

PirateBao validates manifest contract. .bao is cargo ledger, not archive chest. The verifier counts barrels, then complains like a sober quartermaster.

Item	Path
schema	schemas/piratebao-bao-manifest.schema.json
manifest	bao/piratebao.manifest.json
validator	src/shipyard/validateBaoChest.ts
full gate	src/shipyard/verifyHarbor.ts
OpenCode cargo	.opencode/skills/*/SKILL.md + .opencode/commands/*.md

Gate checks manifest schema, key order, referenced files, README inclusion, synced skill copies, OpenCode files, plugin metadata, stale brand tokens, compiled artifacts, shell scripts, npmjs package files, and piratebao.skill contents.

npmjs Package

Package name: piratebao. Registry gate checks availability before publish. npm dry-run checks payload, not vibes. The harbor rejects imaginary treasure; the verifier checks labels before the crate reaches the dock. Painted barrels without rum get thrown back.

Required npmjs fields are set: main, types, exports, bin, files, license, repository, bugs, publishConfig.

Dry-run before publish:

bun run check

Post-publish binary smoke:

bunx -p piratebao piratebao-verify
npx -p piratebao piratebao-verify

Use -p piratebao because the npm package is piratebao while the binary names are specific tools like piratebao-verify and piratebao-compress. That is not a riddle; it is just npm making the plank longer.

package.json files includes README, .bao manifest/schema cargo, OpenCode files, agent plugin files, compiled dist/, shell hooks, and piratebao.skill. Painted barrels without files fail verification. CLI bin entries use npm-normalized paths and shebang-bearing JS so npm does not quietly saw the rudder off during publish dry-run.

Compressor

/piratebao:compress <file> is for natural-language memory files: agent notes, project instructions, todos, and preference docs. It preserves code blocks, inline code, URLs, paths, headings, commands, versions, and proper nouns. It removes prose barnacles, not your mast. If a paragraph is mostly velvet rope, it becomes rope.

Set:

export ANTHROPIC_API_KEY=...
export PIRATEBAO_MODEL=claude-sonnet-4-5-20250929

No CLI fallback. Missing key fails with direct error. No ghost oar under the floorboards, no mystery subprocess paddling toward a rate limit.

Token Bench

Eval snapshots live in evals/snapshots/results.json. Current committed gate: 77% average saved, 68% worst saved. README claims must come from committed snapshot output. No treasure-map fiction; the sea already has enough myths, several consultants, and a kraken who cannot count.

bun run build
node dist/evals/countTreasureTokens.js

Live benchmark needs ANTHROPIC_API_KEY:

node dist/benchmarks/runTreasure.js

Publish Checklist

bun install --frozen-lockfile
bun run check
npm publish --access public

Before publish, confirm piratebao.skill contains only piratebao/SKILL.md, .opencode files appear in npm pack --dry-run --json, README token numbers match evals/README.md, and npm publish --dry-run --access public --json emits no npm auto-correction warnings. Then ship. Quietly. Pirates can be professionals; the cannon is for bugs.
