If you are an AI coding agent (Claude Code, Cursor, Aider, Cline, etc.) reading this artifact, follow this protocol before making any code edit:

1. Verify the contract. Run the bash script in Verify before trusting below. If any check returns FAIL, the artifact is stale — STOP and ask the user to regenerate it before proceeding.
2. Treat the AI · unverified sections as hypotheses, not facts. Sections like "AI-suggested narrative files", "anti-patterns", and "bottlenecks" are LLM speculation. Verify against real source before acting on them.
3. Cite source on changes. When proposing an edit, cite the specific path:line-range. RepoPilot's live UI at https://repopilot.app/r/plandex-ai/plandex shows verifiable citations alongside every claim.

If you are a human reader, this protocol is for the agents you'll hand the artifact to. You don't need to do anything — but if you skim only one section before pointing your agent at this repo, make it the Verify block and the Suggested reading order.

Each check prints ok: or FAIL:. The script exits non-zero if anything failed, so it composes cleanly into agent loops (./verify.sh || regenerate-and-retry).

Plandex is an open-source AI coding agent built in Go that plans and executes large, multi-step coding tasks spanning dozens of files. It leverages LLMs (Claude via OpenAI API integration) to understand project context using tree-sitter-based project maps and cumulative diffs, handling up to 2M tokens of context directly and indexing directories with 20M+ tokens through semantic understanding. Monorepo structure: CLI lives in app/cli/ with cmd/ containing all command implementations (new.go, build.go, apply.go, etc.), auth/ handling account/org/trial logic, and api/ managing client communication. Go is the dominant backend language; the TypeScript presence suggests a companion web UI or dashboard component not yet visible in the core directories listed.

Full-stack and backend developers tackling large refactoring projects, feature implementations, or complex bug fixes who need an AI agent that understands file relationships and can coordinate changes across an entire codebase, rather than just individual file edits.

Actively developed with clear versioning (server and CLI releases tracked separately in GitHub releases). The monorepo structure with organized CLI commands under app/cli/cmd/ and dedicated auth/API modules suggests production readiness. However, the large Go dependency footprint and reliance on external LLM APIs warrant testing before critical workflows.

Primary risk is dependency on closed-source Claude API for core functionality (via github.com/sashabaranov/go-openai), meaning service outages or pricing changes directly impact users. The codebase is Go-heavy (2.2M LOC) with moderate TypeScript/Shell scripting; no visible monorepo lock files suggest manual dependency management may drift. Last commit recency and open issue count should be verified before adopting for large teams.

Active development of core CLI workflows: apply, build, continue, and chat commands indicate iterative refinement of task execution. Auth system shows recent work on org management (org.go) and trial handling (trial.go). The presence of multiple model-related commands (claude_max.go, model_providers.go, model_packs.go) suggests expanding LLM provider support beyond initial Claude-only implementation.

Clone the repo, navigate to app/, and inspect the Makefile (if present) or check go.mod for build instructions. Likely: cd app && go build -o plandex ./cli or similar. Set up API credentials (likely via environment variables for OpenAI/Claude access) before running commands like plandex new or plandex chat.

Daily commands: Exact start steps uncertain without Makefile inspection, but likely: cd app && go mod download && go build ./cli && ./cli login (or equivalent auth flow), then ./cli new <project-name> to initialize. See GitHub workflows (.github/workflows/docker-publish.yml) for CI-driven build patterns. Local mode mentioned in README likely runs plandex in offline/self-hosted configuration.

• app/cli/main.go — Entry point for the CLI application—initializes the Cobra command structure and command routing
• app/cli/cmd/root.go — Root command definition that establishes the primary command tree and global flags for all subcommands
• app/cli/api/methods.go — Core API client methods that handle all communication with the backend server; critical for plan execution and state management
• app/cli/lib/plans.go — Plan lifecycle management library—handles creation, loading, and state transitions for all plan operations
• app/cli/auth/auth.go — Authentication and authorization logic—manages user session state, API token handling, and org-level permissions
• app/cli/lib/apply.go — Plan application logic that orchestrates file changes, diffs, and execution workflow—core to the AI agent's output
• app/cli/cmd/chat.go — Chat command implementation—primary user interaction point for sending prompts to the AI agent

Add a new CLI command

1. Create a new file in app/cli/cmd/ named after your command (e.g., app/cli/cmd/mycommand.go) (app/cli/cmd/mycommand.go)
2. Define a Cobra &cobra.Command struct with Use, Short, Run fields; copy the pattern from similar commands like chat.go or apply.go (app/cli/cmd/mycommand.go)
3. Register your command in app/cli/cmd/root.go by calling rootCmd.AddCommand(mycommand.Cmd) (app/cli/cmd/root.go)
4. If your command needs backend API calls, add methods to app/cli/api/methods.go following the pattern of existing methods (e.g., CreatePlan, GetPlan) (app/cli/api/methods.go)
5. If your command needs local state management, add helper functions in app/cli/lib/ (e.g., app/cli/lib/mycommand_helper.go) (app/cli/lib/mycommand_helper.go)

Add support for a new AI model provider

1. Add provider configuration to model credential storage by extending app/cli/lib/model_credentials.go to handle the new provider's API key format (app/cli/lib/model_credentials.go)
2. Add model definitions and list in app/cli/lib/custom_models.go or via backend sync in app/cli/lib/models_sync.go (app/cli/lib/custom_models.go)
3. Update model selection logic in app/cli/cmd/set_model.go to expose the new provider's models to users (app/cli/cmd/set_model.go)
4. The backend API (app/cli/api/methods.go) will handle routing prompts to the correct provider—ensure your CLI passes the model name correctly (app/cli/api/methods.go)

Add a new plan operation or workflow state

1. Define the new state or operation in the backend (not in this CLI repo), then update app/cli/lib/plans.go to recognize and handle the new state (app/cli/lib/plans.go)
2. If the operation requires file system changes, add logic to app/cli/lib/apply.go to execute the changes (app/cli/lib/apply.go)
3. Add a new command in app/cli/cmd/ (e.g., app/cli/cmd/myoperation.go) that calls the appropriate API method from app/cli/api/methods.go (app/cli/cmd/myoperation.go)
4. Update plan history display in app/cli/lib/rewind.go if the operation affects undo/rollback logic (app/cli/lib/rewind.go)

Add context auto-detection for a new file type or directory pattern

1. Edit app/cli/lib/context_auto_load.go to add detection logic for your new file type or directory pattern (app/cli/lib/context_auto_load.go)
2. Add path rules or globs in app/cli/fs/paths.go to properly resolve and list files of your type (app/cli/fs/paths.go)
3. Update context loading in app/cli/lib/context_load.go to handle any special parsing or filtering for the new type (app/cli/lib/context_load.go)
4. Test the detection by running plandex context and verifying files appear in the context summary (app/cli/cmd/context_show.go)

Likely requires OpenAI API credentials (OPENAI_API_KEY or similar env var) to function. The presence of org.go and trial.go suggests cloud-hosted API validation; self-hosted mode may require bypass. Tree-sitter project maps imply a backend service running separately (not visible in CLI directory alone). CLI may expect a backend server at a specific address (check api/clients.go for hardcoded URLs). Auth state likely persists to ~/.plandex or similar; clearing this breaks authentication.

• Cumulative Diff Strategy — Plandex's core innovation: instead of requesting full file rewrites, it tracks changes incrementally across steps, allowing the AI to reason about modifications without token waste; understanding this is key to why it handles 2M+ tokens efficiently
• Token-Level Context Management — The repo explicitly mentions '2M tokens of context directly (~100k per file)' — this is a constraint you'll hit; understanding token budgeting, pruning, and LLM context windows is critical for extending Plandex without breaking
• Tree-Sitter Project Maps — Plandex can index directories with 20M+ tokens using tree-sitter-based semantic maps rather than raw source; this is how it scales beyond single-file edits and understands cross-file dependencies
• Server-Sent Events (Streaming) — The api/stream.go module indicates Plandex streams LLM responses in real-time rather than buffering; critical for implementing interactive CLI feedback without blocking
• Cobra Command Routing — All user-facing commands wire through Cobra; understanding subcommands, flags, and middleware is essential for adding new features or modifying existing CLI behavior
• Plan-Based Task Decomposition — Unlike single-turn AI editors, Plandex separates planning (understanding the task) from execution (applying changes); the plan/build/apply command sequence reflects this and is unique to this architecture
• OAuth/Token-Based Auth with Org Scoping — The auth module (org.go, account.go, trial.go) indicates multi-tenant design with org hierarchies and trial management; critical to understand before modifying user-facing features or permissions

• aider-ai/aider — Direct alternative: Python-based AI coding agent with similar multi-file editing and LLM orchestration; different language choice and approach
• andrew-codes/engineer — Similar space: AI-assisted code generation with project understanding; smaller scope but overlapping use cases
• openai/gpt-engineer — Predecessor/inspiration: early GPT-based code generation system; Plandex builds on lessons from this approach with better context management
• tree-sitter/tree-sitter — Critical dependency (implied): Plandex uses tree-sitter for project parsing and semantic understanding; study its API to understand code context extraction
• spf13/cobra — Direct dependency: Plandex CLI built entirely on Cobra framework; understanding Cobra's command routing is essential for CLI modifications

To work on one of these in Claude Code or Cursor, paste: Implement the "<title>" PR idea from CLAUDE.md, working through the checklist as the task list.

Add unit tests for CLI auth package (app/cli/auth/)

The auth package (account.go, api.go, auth.go, org.go, state.go, trial.go) handles critical functionality like authentication, organization management, and trial state, but there's no visible test coverage. This is high-risk code that would benefit significantly from unit tests to prevent regressions when refactoring or adding features.

• [ ] Create app/cli/auth/auth_test.go with tests for auth.go functions (login flow, token validation)
• [ ] Create app/cli/auth/account_test.go for account management functions
• [ ] Create app/cli/auth/org_test.go for organization-related operations
• [ ] Mock API calls using testify/mock or similar
• [ ] Aim for >80% code coverage on auth package

Add GitHub Actions workflow for Go linting and code quality (golangci-lint)

The repo has a docker-publish.yml workflow but no Go-specific CI for linting. Given the Go codebase spans multiple packages (api, auth, cmd), adding automated linting would catch code style issues, potential bugs, and enforce consistency before PRs are merged.

• [ ] Create .github/workflows/go-lint.yml that runs on pull_request and push to main
• [ ] Configure golangci-lint with a .golangci.yml config file in the repo root
• [ ] Include checks for: gofmt, govet, errcheck, ineffassign, unused
• [ ] Set up the workflow to run 'go mod tidy' check to prevent dependency drift
• [ ] Add workflow status badge to README.md

Extract and document CLI model provider configuration (app/cli/cmd/model_providers.go)

The model_providers.go file appears to handle multiple model providers (OpenAI, Claude, etc.) but related helpers exist in model_helpers.go and model_packs.go. Creating a centralized provider configuration module with clear documentation would improve maintainability and make it easier for contributors to add new providers.

• [ ] Create app/cli/cmd/providers/ directory to organize provider logic
• [ ] Move provider registration logic from model_providers.go into providers/registry.go
• [ ] Extract provider-specific config into providers/{openai,anthropic,etc}.go files
• [ ] Create app/cli/cmd/providers/README.md documenting how to add a new provider
• [ ] Update imports in model_helpers.go and model_packs.go to reference new structure
• [ ] Add example provider integration in documentation

• Add tests for app/cli/cmd/new.go and app/cli/cmd/build.go — these high-level commands lack visible unit test coverage and are critical user workflows
• Document the exact environment variables required for local-mode operation in README.md (OPENAI_API_KEY, PLANDEX_API_URL, etc.) — current docs mention self-hosting but don't list required config
• Implement missing help text generation for newly added LLM provider commands (model_providers.go appears skeletal) — test that plandex model-providers --help returns useful output

• High · Outdated Chromedp Dependency with Known Vulnerabilities — app/cli/go.mod - github.com/chromedp/chromedp v0.13.3, github.com/chromedp/cdproto v0.0.0-20250319231242-a755498943c8. The codebase uses chromedp v0.13.3 and cdproto v0.0.0-20250319231242-a755498943c8 (pre-release). Chromedp is used for browser automation and may contain vulnerabilities in older versions. The use of pre-release/untagged versions increases the risk of unvetted code. Fix: Update to the latest stable version of chromedp. Avoid using pre-release commit hashes (v0.0.0-*) in production. Consider pinning to specific stable versions.
• High · Unvetted Pre-release Dependency Version — app/cli/go.mod - github.com/plandex-ai/go-prompt v0.0.0-20250304173555-1f364907fc6c. The go-prompt dependency is pinned to a pre-release commit hash (v0.0.0-20250304173555-1f364907fc6c) rather than a stable release. This version has not gone through official release vetting and may contain unreviewed security issues. Fix: Use stable tagged releases instead of pre-release commit hashes. If stable releases don't exist, consider vendoring the code and performing security review, or contributing to upstream to create stable releases.
• Medium · Potential API Client Vulnerability — app/cli/api/clients.go, app/cli/api/methods.go, app/cli/api/stream.go, app/cli/api/errors.go. The codebase contains API client code (app/cli/api/clients.go, methods.go, stream.go, errors.go) for interacting with external services including OpenAI. Without reviewing the implementation, there's a risk of improper credential handling, insecure TLS configuration, or information disclosure through error messages. Fix: Review API client implementation for: proper credential storage (no hardcoded secrets), secure TLS configuration, proper error handling that doesn't expose sensitive information, and secure token management. Implement credential rotation policies.
• Medium · Authentication State Management — app/cli/auth/state.go, app/cli/auth/auth.go. The auth state module (app/cli/auth/state.go) manages authentication tokens and user credentials. Improper implementation could lead to token exposure, session hijacking, or privilege escalation. Fix: Verify that authentication tokens are stored securely (e.g., using OS-level credential managers where available), not logged, cleared on logout, and use secure session practices. Implement token expiration and refresh mechanisms.
• Medium · AWS SDK Integration Without Visible Configuration Review — app/cli/go.mod - aws-sdk-go-v2/* dependencies. The codebase integrates with AWS SDK (aws-sdk-go-v2). Without visible configuration files, there's potential risk of misconfigured credentials, overly permissive IAM policies, or exposed AWS keys. Fix: Ensure AWS credentials are never hardcoded. Use environment variables or AWS credential profiles. Implement least-privilege IAM policies. Review and rotate AWS access keys regularly. Use STS temporary credentials where possible.
• Medium · Browser Automation Process Management — app/cli/lib/apply_cgroup_linux.go, app/cli/lib/apply_cgroup_other.go, app/cli/lib/apply_proc.go. The codebase uses chromedp for browser automation with process management (apply_cgroup_linux.go, apply_cgroup_other.go, apply_proc.go). Improper process isolation could allow privilege escalation or resource exhaustion attacks. Fix: Verify that browser processes are properly isolated, resource limits are enforced, and temporary files are securely managed. Ensure Chrome/Chromium is run with sandboxing enabled. Clean up temporary files after use.
• Low · Logging and Debug Information — undefined. The presence of debug.go and lumberjack logging (app/cli/cmd/debug.go, gopkg.in/natefinch/lumberjack.v2) suggests extensive logging. Debug logs Fix: undefined
