• To regenerate the JavaScript SDK, run ./packages/sdk/js/script/build.ts.
• To rebuild the opencode package, run bun run script/build.ts from packages/opencode. This requires full network access (required_permissions: ["full_network"]).
• ALWAYS USE PARALLEL TOOLS WHEN APPLICABLE.
• The default branch in this repo is dev.
• Local main ref may not exist; use dev or origin/dev for diffs.
• Prefer automation: execute requested actions without confirmation unless blocked by missing info or safety/irreversibility.

Style Guide

General Principles

• Keep things in one function unless composable or reusable
• Avoid try/catch where possible
• Avoid using the any type
• Prefer single word variable names where possible
• Use Bun APIs when possible, like Bun.file()
• Rely on type inference when possible; avoid explicit type annotations or interfaces unless necessary for exports or clarity
• Prefer functional array methods (flatMap, filter, map) over for loops; use type guards on filter to maintain type inference downstream

Naming

Prefer single word names for variables and functions. Only use multiple words if necessary.

Naming Enforcement (Read This)

THIS RULE IS MANDATORY FOR AGENT WRITTEN CODE.

• Use single word names by default for new locals, params, and helper functions.
• Multi-word names are allowed only when a single word would be unclear or ambiguous.
• Do not introduce new camelCase compounds when a short single-word alternative is clear.
• Before finishing edits, review touched lines and shorten newly introduced identifiers where possible.
• Good short names to prefer: pid, cfg, err, opts, dir, root, child, state, timeout.
• Examples to avoid unless truly required: inputPID, existingClient, connectTimeout, workerPath.

// Good
const foo = 1
function journal(dir: string) {}

// Bad
const fooBar = 1
function prepareJournal(dir: string) {}

Reduce total variable count by inlining when a value is only used once.

// Good
const journal = await Bun.file(path.join(dir, "journal.json")).json()

// Bad
const journalPath = path.join(dir, "journal.json")
const journal = await Bun.file(journalPath).json()

Destructuring

Avoid unnecessary destructuring. Use dot notation to preserve context.

// Good
obj.a
obj.b

// Bad
const { a, b } = obj

Variables

Prefer const over let. Use ternaries or early returns instead of reassignment.

// Good
const foo = condition ? 1 : 2

// Bad
let foo
if (condition) foo = 1
else foo = 2

Control Flow

Avoid else statements. Prefer early returns.

// Good
function foo() {
  if (condition) return 1
  return 2
}

// Bad
function foo() {
  if (condition) return 1
  else return 2
}

Schema Definitions (Drizzle)

Use snake_case for field names so column names don't need to be redefined as strings.

// Good
const table = sqliteTable("session", {
  id: text().primaryKey(),
  project_id: text().notNull(),
  created_at: integer().notNull(),
})

// Bad
const table = sqliteTable("session", {
  id: text("id").primaryKey(),
  projectID: text("project_id").notNull(),
  createdAt: integer("created_at").notNull(),
})

Testing

• Avoid mocks as much as possible
• Test actual implementation, do not duplicate logic into tests
• Tests cannot run from repo root (guard: do-not-run-tests-from-root); run from package dirs like packages/opencode.

Type Checking

• Always run bun typecheck from package directories (e.g., packages/opencode), never tsc directly.
