From 5b8503fcd9345ab72d11ed69275fe8e70fcb714e Mon Sep 17 00:00:00 2001 From: Muhammad Zakir Ramadhan <61570975+zakirkun@users.noreply.github.com> Date: Wed, 2 Sep 2026 17:30:18 +0700 Subject: [PATCH] Initial commit: shiro-neko 0.1.0-beta.1 Agentic coding CLI on Bun, Ink, and the AI SDK. Core: streamText loop with SDK-level tool approval so a denied call provably never executes; endpoint fallback for OpenAI reasoning models; retry with backoff. Tools: read/write/edit/glob/grep/bash, path-jailed, gitignore-aware, ripgrep with a JS fallback, binary rejection, live bash streaming. Agents: five variants crossing thinking level with tool restriction; plan and review withhold mutating tools from the model. Extensibility: frontmatter skills with on-demand bodies, plugin host with blocking hooks, MCP stdio and HTTP, read-only subagents. State: durable per-project memory, session task lists, session persistence, compaction that repairs provider-item dependencies. Distribution: five-platform cross-compiled binaries with checksums, install scripts, CI on three operating systems. 404 tests, typecheck clean. --- .github/workflows/ci.yml | 25 ++

Binary rejection. Live-streaming `bash` output. + +**Interface** — Ink TUI with markdown rendering, slash command menu, readline input with +per-project prompt history, coloured diffs in approval prompts, and panels for tasks, +subagents, command output, questions, and command results. + +**Agents** — five variants crossing thinking level with tool restrictions. `plan` and +`review` withhold mutating tools from the model rather than discouraging them. + +**Skills** — frontmatter markdown, catalogue in the prompt and body on demand. Four bundled, +overridable per user and per project. + +**Plugins** — tool contribution, auto-approval, `beforeToolCall` blocking, `afterTurn` +hooks, prompt appendices. `guard` refuses irreversible shell commands ahead of any approval, +including under `--yolo`. + +**Memory and state** — durable per-project memory with hit-counted recall and model-driven +compaction. Session task lists with four states. Session persistence with resume. Context +compaction that repairs the provider-item dependencies pruning breaks. + +**Subagents** — read-only `task` with `explore` and `review` flavours, progress streamed to +a panel. + +**Asking** — the `ask` tool, withheld in headless runs rather than left to hang. + +**MCP** — stdio and HTTP servers, tools namespaced `mcp____`, a failing server +reported rather than fatal. + +**Distribution** — five-platform cross-compiled binaries, checksums, install scripts, CI on +three operating systems, tag-driven releases. + +--- + +## Next + +### Visible process + +The agent's reasoning is discarded. `reasoning-delta` already arrives from the session; the +transcript drops it. A collapsed panel showing what the model is thinking, expandable with a +key, is the largest gap between this and a tool that feels responsive on a slow turn. + +Also missing: which file is being read or written as it happens. `tool-call` events carry +the path but the transcript only shows a one-line summary after the fact. + +### Message queue + +Typing during a turn does nothing. It should queue and run when the turn ends. Interrupting +with `esc` then retyping loses the thought. Requires input to stay live while `busy`, which +means the prompt and the spinner have to coexist rather than swap. + +### More tools + +Measured cost: 553 characters of schema per tool, sent every request. Thirteen live tools is +already at the point where selection accuracy starts to matter, so the next additions need +`activeTools` gating per set before the count grows. + +Ordered by value per line of code: + +- `multi_edit` — several edits to one file atomically, killing read-edit-read-edit churn +- `list_dir` — a tree view, so the model stops globbing blindly to orient +- `read_many_files` — batch reads in one round trip +- git read-only set — `git_status`, `git_diff`, `git_log`, `git_show`, `git_blame`, all + approval-free because they cannot mutate +- `web_fetch` — URL to markdown + +Declined: wrappers around a single bash line with no added guarantee. `run_tests`, +`typecheck`, `lint`, `build` are five tools of pure schema tax when the real commands are +already in `AGENTS.md`. + +### `@file` completion + +Typing `@src/` should complete paths. The last real ergonomic gap in the input. + +--- + +## Later + +**Subagent parallelism.** Two independent searches run sequentially today. The panel already +handles multiple agents; the loop does not fan out. + +**Session branching.** Fork a session at a message to try a different approach without +losing the original. + +**Cost budgets.** A per-session ceiling that warns, then stops. Pricing and accounting exist; +the limit does not. + +**Structured diff review.** Approve or reject individual hunks of an `edit_file` call rather +than the whole thing. + +**Plugin loading from disk.** Plugins are compiled in. Loading `.shiro/plugins/*.ts` needs a +sandbox story first — a plugin that can block tool calls can also lie about blocking them. + +**Prompt caching.** Anthropic and OpenAI both support it. The system prompt is rebuilt every +step for task-list freshness, which defeats a naive cache; splitting the stable prefix from +the volatile suffix would fix that. + +--- + +## Declined + +**A web UI.** This is a terminal tool. A browser front end doubles the surface area and +serves a different product. + +**Model-agnostic prompt tuning.** Per-model prompt variants are a maintenance treadmill for +gains that evaporate on the next model release. + +**Auto-commit.** The agent should never write git history without being asked. Commits are +the user's record of their own work. + +**Vector search over the codebase.** ripgrep answers a scoped question in 135 ms with no +index to build, invalidate, or ship. An embedding store is a large amount of machinery for a +worse answer on a codebase that fits in a grep. + +**Tool call retries on model error.** A model that produced a malformed call will usually +produce it again.

Queueing that would prompt the user for a call +that is already settled, so automatic requests are skipped and denial is surfaced from +`tool-approval-response` instead. + +## Where state lives + +The system prompt is rebuilt on **every step**, not once per turn: + +```ts +prepareStep: ({ messages }) => { + const instructions = this.systemFor(); // task list, memory, skills, agent + if (estimateTokens(messages) <= threshold) return { instructions }; + return { instructions, messages: prunePreservingItems({ messages, reasoning: 'all', ... }) }; +} +``` + +That is not an optimisation. A `todo_write` on step one must be visible to step two, and +`system:` on `streamText` is bound once for the whole run. Returning `instructions` from +`prepareStep` is the only place per-step state can enter. + +The prompt also describes only the tools actually offered this turn. A prompt that mentions a +withheld tool teaches the model to attempt impossible calls. + +## Rendering + +Ink re-renders the whole tree on every `setState`. At 50 tokens a second that is 50 full +renders and a visibly flickering terminal. + +Two things fix it: + +- Finished lines go into ``, rendered once and never redrawn. +- Token deltas accumulate in a ref and flush on a 60 ms interval, not per token. + +Markdown is parsed on every flush. An unclosed fence renders as a code block that grows, +which is what a reader expects while text is still arriving. + +## Input + +`ink-text-input` was replaced. It discards up and down before its own handler, so history +recall is impossible, and it only ever *shrinks* its internal cursor offset, so an externally +set value leaves the cursor stranded mid-string. + +`src/ui/PromptInput.tsx` owns the cursor. That also gives home, end, and ctrl-a/e/k/u/w for +free. It hands up, down, tab, and escape to a parent callback first, so the command menu and +open panels can claim them before the input treats them as editing keys. + +## Subagents + +`task` runs a nested `streamText` with only `read_file`, `glob`, and `grep`. It returns one +message. + +Two consequences follow from the tool set, not from policy: + +- It can never need approval, because it has no gated tools. +- The parent's context holds the findings, not the search transcript. + +Progress is reported through a callback, wired to a bus the panel subscribes to. Without the +bus the panel would need a reference to the tool, and the tool would need one to React. + +## Provider differences + +Two are handled explicitly. + +**Thinking levels.** `off`/`low`/`medium`/`high`/`max` become `reasoning_effort` on OpenAI and +a `thinking` token budget on Anthropic. The SDK does the mapping; `src/agents.ts` only picks +the level. + +**Endpoint fallback.** Newer OpenAI models reject function tools on `/v1/chat/completions` +and require `/v1/responses`. `src/fallback.ts` presents both as one model and switches when +the first rejects the request *shape* — 400, 404, 405, 415, 422, 501 with `isRetryable` false. +Retryable failures are left to the SDK's backoff. + +The switch is sticky. Once an endpoint rejects the shape it will reject every later step too, +so re-probing it each turn would waste a round trip per step. + +Only `api.openai.com` gets the chain. Third-party endpoints do not implement `/v1/responses`. + +## Compaction and its repair + +`pruneMessages({ reasoning: 'all' })` strips a reasoning item and keeps the message item from +the same response. The responses API treats the message as that reasoning item's dependent +and returns 400. + +The two carry different ids, so they cannot be matched by id. What links them is the assistant +message they arrived in: one message is one response, and its reasoning item covers every +other item in it. `src/prune.ts` drops the dependent parts of any turn whose reasoning was +removed — which costs nothing, since pruning was already discarding those turns. + +## Module map + +| Module | Responsibility | +|---|---| +| `session.ts` | the loop, approvals, compaction, event stream | +| `tools.ts` | file and shell tools, ripgrep bridge, bash streaming | +| `ignore.ts` | gitignore-aware walker, path jail | +| `prompt.ts` | system prompt assembly from live state | +| `agents.ts` | variants, thinking levels | +| `skills.ts` | discovery, catalogue, `skill` tool | +| `memory.ts` | durable notes, search, model compaction | +| `notebook.ts` | session task list | +| `plugins.ts` | host, hooks, guard chain | +| `subagent.ts` | `task` tool and progress events | +| `ask.ts` | the `ask` tool | +| `mcp.ts` | MCP clients and namespacing | +| `fallback.ts` | endpoint chain | +| `prune.ts` | provider-item repair | +| `markdown.ts` | parser, no dependency | +| `store.ts` | sessions, prompt history | +| `config.ts` | resolution, model construction | +| `providers.ts` | presets, `/models` fetch | +| `pricing.ts` | USD rates | +| `commands.ts` | slash registry, parsing, menu matching | +| `headless.ts` | `-p` mode | +| `cli.tsx` | argv, wiring, lifecycle | +| `ui/*` | Ink components | + +Every module is pure of the UI except `ui/`, and `ui/` never touches the SDK.
