Codeflow

@aharness/codeflow executes a recipe-driven development workflow as an installable aharness FSM command.

Codeflow is intended for large specs where one implementation plan would be too large, stale, or risky. The FSM reads an implementation roadmap and executes it fully autonomously, slice by slice. It has the following features:

• Fully autonomous slice execution.
• Context management: clears context between steps.
• Model settings: changes model and effort level as required per state.
• Slice planning: writes a detailed implementation plan for each roadmap slice.
• Roadmap and slice repair: replans or fixes issues encountered during a run.
• Resume support: resumes from previous runs.
• Git worktree support.

For smaller work that fits in one bounded implementation plan, you usually do not need the roadmap-plus-FSM workflow.

Install

aharness install @aharness/codeflow

Install Process Skills

Install the process skills for pre-FSM work with npx skills:

npx skills add Alfredvc/codeflow

Do not install internal-skills/ with npx skills; aharness loads those only inside the FSM.

Workflow

Codeflow assumes the idea has been developed before the FSM starts. A typical flow is:

1. Start with a loose discussion with the agent about the idea. Ask it to investigate, inspect code, research constraints, and ask questions until the direction feels worth capturing.
2. Use writing-ideas to capture the approved idea in docs/ideas/.
3. Use grill-me to challenge the ideafile, remove ambiguity, and settle scope, behavior, constraints, acceptance criteria, and important decisions.
4. Use writing-specs to turn the grilled idea into a design spec in docs/specs/. This skill dispatches a review agent with reviewing-specs.
5. Clear the session with /clear, then ask the agent to use writing-implementation-roadmaps to write an implementation roadmap from the spec. The roadmap skill dispatches a fresh roadmap review agent.
6. Run aharness run recipe-driven-development with the roadmap path. The FSM writes the detailed plan for the current slice internally, reviews it, executes it, verifies it, commits the accepted slice, and advances until the roadmap is complete.

Command

recipe-driven-development

Inputs:

• --roadmap-path <path>: implementation roadmap file to resume or execute.
• --worktree <boolean>: create and use a temporary git worktree under /tmp. Defaults to false.

Repair and recovery budgets are internal safety guards. When they are exhausted, the FSM records a durable restart handoff instead of continuing to improvise.

Bundled Skills

The package ships these user-facing process skills for work before the FSM is invoked:

• writing-ideas: captures an approved idea as a short grounding document in docs/ideas/.
• grill-me: challenges the idea to resolve scope, behavior, constraints, acceptance criteria, and decisions before writing a spec.
• writing-specs: turns an approved and grilled idea into a design spec in docs/specs/.
• reviewing-specs: reviews design specs for weak assumptions, missing research, edge cases, shortcuts, and product fit.
• writing-implementation-roadmaps: decomposes a large spec or architecture design into staged roadmap slices for the FSM.

Embedding This FSM

If you want to call Codeflow from another aharness FSM, add @aharness/codeflow as a dependency and import the exported FSM module directly. The install command metadata is only for aharness CLI installation; it is not the API for embedding Codeflow in another FSM.

{
"dependencies": {
"@aharness/core": "^0.1.1",
"@aharness/codeflow": "^0.1.0"
}
}

Import the published subpath:

importrecipeDrivenDevelopment,{machineasrecipeDrivenDevelopmentMachine,typeRecipeDrivenDevelopmentFinals,typeRecipeDrivenDevelopmentInput,typeRecipeDrivenDevelopmentMachine,typeRecipeDrivenDevelopmentOutput,}from"@aharness/codeflow/recipe-driven-development.fsm.js";

The default export and named machine export are the same FSM. The public type aliases cover the child machine, its expected input, its final-state output map, and the successful complete output. Internal recipe/control-flow data types remain private.

Example wrapper embed:

import{createFsm}from"@aharness/core";importrecipeDrivenDevelopment,{typeRecipeDrivenDevelopmentInput,}from"@aharness/codeflow/recipe-driven-development.fsm.js";interfaceWrapperData{readonlyroadmapPath: string;}constfsm=createFsm<WrapperData>();exportdefaultfsm.machine({id: "wrapper",data: (): WrapperData=>({roadmapPath: "docs/plans/roadmap.md"}),initial: "runCodeflow",states: {runCodeflow: fsm.embed(recipeDrivenDevelopment,{input: (data): RecipeDrivenDevelopmentInput=>({roadmapPath: data.roadmapPath,worktree: false,}),on: {complete: {to: "complete"},failed: {to: "failed"},},}),complete: fsm.final({outcome: "success"}),failed: fsm.final({outcome: "failure"}),},});
