Project Implementation Plan

You are an expert software engineer. Implement the following project carefully, with minimal errors, following the plan, stack, and standards below. Ask clarifying questions only if truly necessary; otherwise proceed.

1. Project Overview

• Name: some-cardputer-adv-programs
• Description: some cardputer adv programs
• Type: cli
• Audience: developers
• Scale: small
• Created: 2026-10-25T16:54:22.328466564+00:00

2. Requirements

• project_type: cli
• database: none
• auth: none
• deployment: local
• scale: small
• feature: some cardputer adv programs

3. Chosen Stack

• Language: Rust
• Libraries: clap, serde, toml, serde_json, tracing
• Rationale: Rust chosen for cli project (scale: small).

4. Libraries (details)

• clap (rust, cli): Command-line argument parsing — derive macros
• serde (rust, serialization): Serialize/deserialize — derive
• toml (rust, serialization): TOML parsing
• serde_json (rust, serialization): JSON serialization
• tracing (rust, observability): Structured logging/tracing

5. Architecture

Single binary CLI. Flow: main -> cli (clap) -> command dispatch -> domain logic -> io. Modules: main, cli, config, manifest, pack, hub, update, error, io. Use anyhow at boundaries, thiserror in library code. Keep main thin; all logic in lib/testable modules.

6. Suggested File Structure

• Cargo.toml
• README.md
• src/cli.rs
• src/config.rs
• src/error.rs
• src/main.rs
• tests/cli.rs

7. Feature Plan

• some cardputer adv programs

8. Implementation Plan (Milestones)

M0: Setup — Project scaffolding, tooling, CI

• [ ] M0-1 Scaffold project from template: Generate files, install deps.
• [ ] M0-2 Configure lint/format/test: Set up formatters and CI. (depends on: M0-1)

M1: Core — Implement core domain logic

• [ ] M1-1 Define data models: Structs/schemas for domain entities. (depends on: M0-1)
• [ ] M1-2 Implement core operations: Business logic with tests. (depends on: M1-1)

M2: Features — Deliver user-facing features

• [ ] F1-1 some cardputer adv programs: Implement and test: some cardputer adv programs (depends on: M1-2)

M-Final: Polish — Docs, tests, release

• [ ] MF-1 Documentation: README, usage, examples.
• [ ] MF-2 Release build: Deploy target: local

9. Coding Standards

• Use strict typing; avoid any/unwrap in production paths.
• Handle errors explicitly; no silent failures.
• Add unit tests for core logic; integration tests for boundaries.
• Keep functions small; single responsibility.
• Document public API.
• Run cargo fmt, clippy; fix all warnings.
• Prefer anyhow for app errors, thiserror for library errors.

10. Risks & Mitigations

• Tar path traversal and accidental inclusion of secrets in bundles.
• Self-update supply chain: verify checksums; support rollback.
• Hub API drift and versioning; handle 401/403/404 gracefully.
• Unstable --json output breaking agent consumers.
• Version conflicts and non-deterministic packaging.

Common Pitfalls

• Skipping tests until the end; regressions accumulate.
• Blocking the terminal with long-running tasks without progress output.
• Poor arg validation and unclear error messages.
• Not handling SIGINT/Ctrl-C gracefully.
• Overusing clone() instead of references.
• unwrap() panics in production paths.
• Blocking async runtime with sync I/O.

11. Template Used

• cli-tool

Language Guidance

Rust Project Guidance

Project Layout

• Prefer a workspace for multi-crate projects.
• Binary crate: src/main.rs thin; logic in src/lib.rs or modules.
• Library crate: src/lib.rs public API; internal modules private.
• Tests: tests/ integration; unit tests co-located.

Error Handling

• Libraries: define enum Error with thiserror.
• Applications: use anyhow::Result at boundaries.
• Avoid unwrap()/expect() in production.

Design Patterns

• Newtype, Builder, trait objects, From/Into, Default, enum state machines, RAII/Drop, interior mutability.

Async

• Use tokio; avoid blocking in async; use spawn_blocking; channels for message passing.

Testing

• Unit + integration; property tests with proptest.

Tooling

• cargo fmt, clippy, test, doc, audit, deny.

Common Crates

• CLI: clap, dialoguer, indicatif, console, tracing.
• Web: axum, actix-web, reqwest, tower, tower-http.
• DB: sqlx, diesel, sea-orm.
• Errors: thiserror, anyhow, miette.
• Testing: proptest, mockall, wiremock, assert_cmd.

Final Instructions to the LLM

1. Follow the milestones in order; do not skip setup.
2. Use ONLY the chosen stack and libraries unless a strong reason exists; explain deviations.
3. Produce complete, runnable code for each file in the suggested structure.
4. Include tests for core logic.
5. Handle errors and edge cases; no panics in production paths.
6. End with a short summary of what was implemented and how to run it.
