Show HN: Yet Another OpenCode Plugin

A developer released Yet Another OpenCode Plugin, an opencode plugin that adds terse response modes, a YAGNI-based 'lazy dev' ruleset, and two read-only agents (Review and Dream) to the opencode AI coding assistant. The plugin, installable via npm, bunx, npx, or pnpm dlx, configures settings in ~/.config/opencode/yaop.json and supports both opencode.json and opencode.jsonc files.

An opencode https://opencode.ai plugin that merges the best of two worlds: Terse, direct responses — single low intensity: trim filler and hedging, keep full sentences, preserve technical terms verbatim. Auto-clarity drops the terseness on security warnings, irreversible actions, and ambiguity. Lazy dev — YAGNI ladder before writing code, reuse over reinvention, bug fix = root cause not symptom, strict calibration at trust boundaries, one runnable check per non-trivial change. Plus two read-only primary agents: Review — always runs the full protocol: functional YAGNI, overengineering, dead code, root cause and four non-functional layers performance, security, maintainability, architecture , using pattern skills and conditional deep-dive subagents. Dream — a planner that settles the architectural decisions of a new build before code is written, asking only what matters and handing a plan to Build. Get the CLI, then register the plugin in an opencode config. Globally the command lands in your PATH , or on demand with bunx / npx / pnpm dlx no PATH pollution : npm install -g <package-or-tarball or: bun install -g ... or on demand — any of these are equivalent bunx --bun yet-another-opencode-plugin install --global npx yet-another-opencode-plugin install --global pnpm dlx yet-another-opencode-plugin install --global --bun is a bunx -only flag; it is optional and not supported by npx / pnpm dlx . yet-another-opencode-plugin install adds the entry: --global targets ~/.config/opencode/opencode.json , the default targets ./opencode.json . Until the package is published to npm, register the local build instead: after bun run build , use the local plugin file bunx --bun yet-another-opencode-plugin install --global --entry-file --entry-file writes the local dist/plugin.mjs path instead of the package name. The Review and Dream agents, the Review's deep-dive subagents, and the skill paths are registered at runtime by the plugin — no manual editing. Both opencode.json and opencode.jsonc are supported; JSONC files are edited in place, preserving comments and formatting. Review agent — cycle with Tab to the review agent, then ask it to review e.g. "review the changes" . It is read-only, like Plan: it always runs the full protocol and reports; it never edits. Dream agent — cycle with Tab to the dream agent to settle the architectural decisions of a new build before code is written. It is read-only: it asks the decisions that matter and hands a plan to Build. Ruleset — the yaop communication + engineering rules are embedded by default in the review and dream agent prompts. The main Build/Plan agents are untouched. opencode validates opencode.json strictly, so plugin settings live in ~/.config/opencode/yaop.json : { "yaop": { "review": { "model": "anthropic/claude-haiku-4-20250514", "deepDiveThreshold": "high", "parallelSkills": true }, "dream": { "model": "anthropic/claude-haiku-4-20250514" } } } | Key | Default | Meaning | |---|---|---| review.model | inherit global | Override the model for the Review agent. Omit to use your global model; change at any time via /models . | review.deepDiveThreshold | "high" | Severity at or above which the Review spawns the matching deep-dive subagent. critical | high | medium | never . | review.parallelSkills | true | Analyze the four NFR layers in parallel true or one at a time false . | review.deepDiveSubagents | all true | Per-layer toggle: { "security", "performance", "architecture" } booleans. | dream.model | inherit global | Override the model for the Dream planner. Omit to use your global model. | CLI equivalents: --review.model=MODEL , --review.deepDiveThreshold=T , --review.parallelSkills=true|false , --dream.model=MODEL . — server plugin. Registers the plugin.mjs review primary agent, the dream primary agent, three hidden read-only deep-dive subagents security-deep , performance-deep , architecture-deep , and the yaop-review / yaop-plan skill paths. Both primary agents carry the yaop ruleset embedded in their prompt. Review agent — peer of Build/Plan, read-only: edit = deny , bash = ask git read subcommands allowed , permission.task restricted to its own -deep subagents. Protocol: determine target git diff /status by default → read full context → functional lenses → 4 NFR layers via the yaop-review skill → deep-dive subagent per layer at or above the threshold → one severity-ranked report. Dream agent — peer of Build/Plan, read-only: edit = deny , bash = ask git read subcommands allowed , permission.task denied. Protocol: classify the project kind + concern tags → prune the yaop-plan catalog → drive the question tool over the remaining decisions → confirm the idea → agree the Build execution mode → one concise hand-off plan. Writes no files.— pattern checklists for the four layers and a uniform finding output contract. yaop-review skill— the Dream's decision catalog and signal table, pruned by the project's kind + concern tags. yaop-plan skill bun install bunx tsc --noEmit typecheck bun test tests bun run build bundle plugin + cli, copy markdown assets to dist/ MIT
