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.

# Configuration
|
|
|
|
Settings come from three places. Later wins:
|
|
|
|
1. `~/.shiro-neko/config.json`
|
|
2. environment variables
|
|
3. command-line flags
|
|
|
|
## The config file
|
|
|
|
Written by `/provider`, editable by hand. Every field is optional.
|
|
|
|
```json
|
|
{
|
|
"provider": "openai",
|
|
"model": "gpt-5",
|
|
"baseURL": "https://api.openai.com/v1",
|
|
"apiKey": "sk-...",
|
|
"presetId": "openai",
|
|
"agent": "default",
|
|
"thinking": "medium",
|
|
"maxRetries": 3,
|
|
"plugins": ["guard", "time"],
|
|
"mcpServers": {
|
|
"fs": { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-filesystem", "."] }
|
|
}
|
|
}
|
|
```
|
|
|
|
| Field | Meaning |
|
|
|---|---|
|
|
| `provider` | wire protocol: `anthropic` or `openai`. Not the vendor — Groq, OpenRouter, and Ollama all speak `openai` |
|
|
| `model` | model id as the endpoint names it |
|
|
| `baseURL` | API root. Defaults to the official endpoint for the provider |
|
|
| `apiKey` | sent as `Authorization: Bearer` for `openai`, `x-api-key` for `anthropic` |
|
|
| `presetId` | which preset `/provider` chose, so it can show what is configured |
|
|
| `agent` | default variant: `default`, `quick`, `deep`, `plan`, `review` |
|
|
| `thinking` | default level: `off`, `low`, `medium`, `high`, `max` |
|
|
| `maxRetries` | retries per model call for transient failures. Default 3 |
|
|
| `plugins` | which plugins to enable. Omit for `["guard", "time"]` |
|
|
| `mcpServers` | see [MCP](mcp.md) |
|
|
|
|
## Provider presets
|
|
|
|
`/provider` offers these. Each sets `baseURL` and the wire protocol for you.
|
|
|
|
| Preset | Protocol | Endpoint |
|
|
|---|---|---|
|
|
| Anthropic | `anthropic` | `api.anthropic.com/v1` |
|
|
| OpenAI | `openai` | `api.openai.com/v1` |
|
|
| OpenRouter | `openai` | `openrouter.ai/api/v1` |
|
|
| Groq | `openai` | `api.groq.com/openai/v1` |
|
|
| DeepSeek | `openai` | `api.deepseek.com/v1` |
|
|
| xAI | `openai` | `api.x.ai/v1` |
|
|
| Ollama | `openai` | `localhost:11434/v1` |
|
|
| LM Studio | `openai` | `localhost:1234/v1` |
|
|
| Custom OpenAI-compatible | `openai` | you supply it |
|
|
| Custom Anthropic-compatible | `anthropic` | you supply it |
|
|
|
|
After the key is entered, `GET /v1/models` is called and the list becomes a picker. If the
|
|
endpoint does not implement it, you type the model id instead — the setup still completes.
|
|
|
|
## Environment variables
|
|
|
|
| Variable | Effect |
|
|
|---|---|
|
|
| `SHIRO_PROVIDER` | overrides `provider` |
|
|
| `SHIRO_MODEL` | overrides `model` |
|
|
| `SHIRO_BASE_URL` | overrides `baseURL` |
|
|
| `SHIRO_API_KEY` | overrides `apiKey` |
|
|
| `ANTHROPIC_API_KEY` | used when `provider` is `anthropic` and no key is set |
|
|
| `OPENAI_API_KEY` | used when `provider` is `openai` and no key is set |
|
|
| `SHIRO_HOME` | relocates config, sessions, memory, history, and user skills |
|
|
| `SHIRO_INSTALL_DIR` | where `install:local` and the installers put the binary |
|
|
| `SHIRO_REPO` | which GitHub repo the installers download from |
|
|
| `SHIRO_VERSION` | pins the version the installers fetch |
|
|
|
|
`SHIRO_HOME` is what the test suite uses to keep a run out of your real config.

## Where things live
|
|
|
|
```
|
|
~/.shiro-neko/
|
|
config.json provider, model, key, defaults
|
|
sessions/<uuid>.json transcripts, token counts, cost, task list
|
|
memory/<hash>.json durable per-project notes
|
|
history/<hash>.json prompt history for up-arrow recall
|
|
skills/*.md your own skills
|
|
```
|
|
|
|
Project files:
|
|
|
|
```
|
|
<project>/
|
|
AGENTS.md instructions injected into the system prompt
|
|
.shiro/skills/*.md project skills, override user and builtin
|
|
.shiroignore extra ignore rules on top of .gitignore
|
|
```
|
|
|
|
Memory and history file names are SHA-256 prefixes of the absolute project path, because a
|
|
path is not a safe filename.
|
|
|
|
## OpenAI reasoning models
|
|
|
|
Newer OpenAI models reject function tools on `/v1/chat/completions` and require
|
|
`/v1/responses`. For `api.openai.com` both are chained: a 400, 404, 405, 415, 422, or 501
|
|
on the first switches to the second, sticks for the rest of the session, and prints one
|
|
notice. Retryable failures — 429 and 5xx — are left to the SDK's backoff instead.
|
|
|
|
Third-party endpoints get a plain chat-completions model with no fallback probe, since they
|
|
do not implement `/v1/responses`.
