One CLI for the dev loop. Any language. JSON by default. Read the docs and go.
fledge templates init my-tool --template rust-cli
cd my-tool
fledge lanes init
fledge lanes run ciWorking with AI agents? See AGENTS.md. Every command emits {schema_version: 1, ...}, FLEDGE_NON_INTERACTIVE=1 silences prompts, fledge ask and fledge review are spec-aware, and fledge introspect --json dumps the full command tree. Talks to the Anthropic API, any OpenAI-compatible endpoint (OpenAI, OpenRouter, Groq, ...), or any Ollama endpoint (local, cloud, or self-hosted) over plain HTTP. No CLI required.

fledge run test# runs your language's test command
fledge run build # same for build
fledge run test -- --release # pass extra args through to the command after --
fledge review # AI code review against the default branch

# multi-model panel, parallel critiques on the same diffStarting fresh? Scaffold from a template:
fledge templates init my-app --template rust-cli # built-in
fledge templates init my-app --template user/repo # any GitHub repo
fledge templates init my-app # interactive pickerSwitch AI providers without editing config:
fledge ai use # interactive picker (live Ollama model list)
fledge ai use ollama qwen3-coder:480b-cloud # scriptable
fledge ai status # show active provider/model and where each value came from| Pillar | Commands | What it does |
|---|---|---|
| Scaffold | templates (init, create, list, search, validate, publish) | Start a project from a template, local or remote |
| Run | run, lanes, watch | Task runner, composable pipelines, file-watch reruns |
| Spec | spec | spec-sync. Modules declare their contract, AI uses it as context |
| AI | ai, ask, review | Provider/model selection, spec-aware Q&A, single and multi-model code review |
| Ship | work, release, changelog | Branch and PR flow with AI-drafted bodies, version bump, tag, push |
| Extend | plugins, config, introspect, completions, doctor | Plugin protocol, global config, command-tree introspection, env health |
That is the whole core. Anything else is a plugin.
Plugins extend fledge with community-built commands. Native plugins run as regular executables. WASM plugins run in a sandboxed Wasmtime runtime with no host access by default.
fledge plugins install --defaults # curated native plugin set
fledge plugins create my-lint --wasm # scaffold a sandboxed WASM pluginThree native plugins ship as the default set:
| Plugin | Adds |
|---|---|
fledge-plugin-github | checks, issues, prs. GitHub PR/issue/CI flow |
fledge-plugin-deps | deps. Polyglot lockfile audits |
fledge-plugin-metrics | metrics. LOC, churn, test/source ratio (via tokei + git) |
WASM plugins are ideal for pure-computation tasks (linting, formatting, analysis) where you want strong isolation without trusting arbitrary binaries:
- Sandboxed by default. No filesystem, no network
- Opt-in capabilities prompted at install time
- Fuel-bounded execution (no infinite loops)
- 256 MB memory cap
- Cross-platform single
.wasmbinary
See the WASM plugin guide for authoring details.
Language starters: rust-cli, ts-bun, python-cli, go-cli, ts-node, static-site, kotlin-kmp, kotlin-ktor-api
Setup-only: corvid-stack (CorvidLabs trust toolchain — fledge + spec-sync + augur + attest, no language scaffolding), fledge-plugin (plugin scaffold)
