Memory for Codex
Codex can take on coding tasks quickly. Windy gives those tasks the project memory they need first: specs, architecture, diagrams, decisions, plans, tasks, and execution history that keep generated changes aligned with the design.Works with Codex, Claude Code, Cursor, OpenCode, and MCP-aware coding agents.
Codex executes the task. Windy supplies the source of truth.
Codex-style coding agents are useful when the work is clear. But the task itself is rarely the whole context. A safe implementation also needs the product requirement, architecture, API contracts, constraints, plan, and review criteria. Windy keeps that context in one project-scoped memory Codex can build from.
Windy does not replace Codex. It gives Codex the design memory and execution plan behind the task.
The problem
A coding task without memory is still a partial instruction.
A task can say what to change, but it may not explain why the system is shaped a certain way, which constraints matter, what previous decisions were made, or how success should be checked. When that context is missing, a coding agent may produce a plausible change that does not match the design.
Acceptance criteria are missing or vague.
Review becomes subjective.
Previous decisions are invisible.
The agent may re-open choices the team already made.
Large tasks are under-sequenced.
Migrations and refactors need ordered steps, not one broad instruction.
Execution history gets lost.
Future runs may not know what was already attempted or changed.
Codex becomes more reliable when each task is grounded in the project’s current memory.
Project memory
Give the coding task the context behind the code.
Windy stores the artifacts that explain the intended system, the work plan, and the execution record. That context makes Codex tasks easier to scope, review, resume, and maintain.
- Specs and requirements — intended behavior, edge cases, and acceptance criteria.
- Architecture notes — components, boundaries, constraints, dependencies, and ownership.
- Diagrams — system maps, workflow diagrams, ER diagrams, state machines, and cloud architecture.
- Contracts and schemas — APIs, events, database models, payload shapes, JSON, YAML, and interface definitions.
- Decision records — tradeoffs, rejected alternatives, and the reasons behind the current design.
- Plans and tasks — ordered work with objectives, dependencies, acceptance criteria, and implementation prompts.
- Execution history — what ran, what changed, what passed, what failed, and what still needs review.
The task tells Codex what to do. Project memory tells Codex what it must preserve while doing it.
Workflow
Start with the spec, then execute the task.
Windy turns Codex-style coding into a reviewable loop: capture intent, decompose work, execute a task, review the result, and update the memory.
01
Capture the spec in Windy.
Define behavior, architecture, constraints, edge cases, and acceptance criteria.
02
Create a Windy Plan.
Break large work into ordered tasks with objectives, dependencies, deliverables, and prompts.
03
Give Codex the relevant task context.
The task includes the docs and acceptance criteria Codex should build from.
04
Review against the source of truth.
Check the implementation against the spec, plan, and acceptance criteria.
05
Update memory after execution.
Record what changed and update docs or decisions when behavior evolves.
The next Codex task starts from the current project truth, not a disconnected issue description.
Plans
Make task execution small enough to trust.
Codex is most useful when a task is clear, bounded, and reviewable. Windy Plans help turn broad requirements into ordered tasks with the context and acceptance criteria needed for safe execution.
- Objective — what the task should accomplish.
- Relevant docs — specs, diagrams, architecture, contracts, and decisions the task should use.
- Deliverables — expected code, tests, migrations, docs, or UI changes.
- Dependencies — what must happen before the task can run.
- Acceptance criteria — how the result will be reviewed.
- Implementation prompt — a focused task instruction.
- Execution log — what happened during the run.
A good Codex task is not just a prompt. It is a small, reviewable unit of a larger plan.
What this looks like in practice.
You want Codex to implement usage-based billing for an existing SaaS product.
Without Windy
The task says “add usage-based billing.” Codex has to infer plan limits, metering events, invoice timing, data ownership, webhook behavior, migrations, and review criteria from partial code context.
With Windy
- The billing spec defines usage events, plan limits, invoice timing, and edge cases.
- The architecture note explains which service owns metering and subscription state.
- The API contract defines event payloads and billing lifecycle states.
- The diagrams show checkout, metering, invoice, and webhook flows.
- The plan breaks the work into schema, event capture, billing calculation, invoice sync, tests, and docs tasks.
- Codex executes one task with clear acceptance criteria.
- Execution notes record what changed and what remains.
Codex is not inventing the billing model from the task. It is implementing a design the team can review.
Setup
Give each Codex task a source of truth.
The simplest way to use Windy with Codex is to create a Windy project for the codebase, capture the design context, and use Windy Plans to define the tasks Codex should execute.
01
Create or open a Windy project.
Add the requirements, architecture notes, diagrams, decisions, and constraints that explain the system.
02
Create a plan for the work.
Break the change into ordered tasks with acceptance criteria.
03
Use the task context with Codex.
Give Codex the relevant docs, task objective, dependencies, and acceptance criteria.
04
Record execution.
Keep notes about what changed, what passed, what failed, and what still needs review.
Suggested task instruction
Before implementing this task, use the relevant Windy Docs and current Windy
Plan as the source of truth for behavior, architecture, constraints, acceptance
criteria, and task order. If implementation changes behavior or design, update
the related Windy docs or execution notes.Control
More agent execution needs more durable context.
Windy keeps the human as architect and reviewer. The goal is not to hide work inside an autonomous run. The goal is to make each Codex task easier to understand: what it was supposed to do, what context it used, what changed, and whether it met acceptance criteria.
- Project-scoped source of truth — tasks build from the connected project's memory.
- Explicit acceptance criteria — review starts before implementation.
- Ordered plans — large work becomes sequenced and resumable.
- Execution history — previous runs leave a durable record.
- Human review — developers remain responsible for architecture and approval.
Windy makes Codex work easier to inspect, resume, and trust.
Best-fit use cases
When Windy helps most with Codex.
Task execution with hidden context
features where the ticket is not the full design.
Architecture-sensitive changes
APIs, schemas, service boundaries, event flows, and data ownership.
Large migrations
work that must be broken into safe, ordered tasks.
Long-running implementation plans
tasks that span multiple runs or reviewers.
Team workflows
when multiple developers or agents need the same source of truth.
Codebases where docs must stay current
projects that future agents will need to understand and modify.
FAQ
Questions, answered.
No. Codex executes coding tasks. Windy provides the project memory, specs, plans, and execution record those tasks should use.
A task description is rarely the full design. Codex needs requirements, architecture, decisions, constraints, and acceptance criteria to implement safely.
No. Windy includes documentation, but also plans, tasks, prompts, acceptance criteria, diagrams, and execution history that support agent workflows.
Yes. Windy is designed as a shared memory layer for agent-native development, so the same source of truth can support Claude Code, Cursor, Codex, OpenCode, and future MCP-aware tools.
Start with the relevant requirement, architecture notes, contracts, diagrams, constraints, acceptance criteria, and task plan.
Windy preserves execution notes and keeps docs or plans updated when behavior changes, so the next task starts from current project memory.
