Keen CLI — Phase 1 Progress Evaluation¶

Build & Test Status¶

Check	Status
`go build ./...`	✅ Passes
`go test ./...`	✅ Passes (config, filesystem)

Task-by-Task Assessment¶

Task 1: Project Structure & Go Module ✅ Complete¶

Planned	Actual	Status
`cmd/agent/main.go`	✅ Present	Done
`internal/config/`	✅ Present (config.go, loader.go)	Done
`internal/filesystem/`	✅ Present (guard.go, gitawareness.go)	Done
`internal/cli/`	✅ Present (root.go, repl.go, setup.go)	Done
`configs/system_prompts/`	⚠️ Directory exists, empty	Minimal
`go.mod` with deps	✅ cobra, yaml.v3, go-git, huh	Done

Actual structure matches the plan closely. The addition of configs/providers/ (registry) is a welcome bonus not in the original phase 1 plan but specified in the later CLI design doc.

Task 2: Config System ✅ Complete¶

Design doc: output-4_config-design.md

Requirement	Status	Notes
`GlobalConfig` struct (JSON)	✅	`active_provider`, `active_model`, `providers` map
`ProviderConfig` struct	✅	`models []string`, `api_key string`
`SessionConfig` struct	✅	In-memory only, no persistence
`ResolvedConfig` struct	✅	Final merged config
`Resolve()` function	✅	Session > Global > Default resolution
`Loader` (Load/Save/Exists)	✅	JSON persistence to `~/.keen/configs.json`
`GetProviderConfig()`	✅
`SetProviderConfig()`	✅
`AddModel()`	✅	Dedup logic included
`GetFirstModel()`	✅
`ConfigPath()` / `ConfigDir()`	✅
0600 file permissions	✅	In `loader.go` Save()
Unit tests	✅	13 tests across `config_test.go` and `loader_test.go`

[!TIP] The config system is one of the most complete parts of the codebase — fully matching the design doc with good test coverage.

Minor deviation: The design doc has SetProviderConfig returning an error, but the implementation is void (no error return). The current implementation silently initializes the map if nil, which is fine.

Task 3: FileGuard ✅ Complete¶

Requirement	Status	Notes
`Permission` type (Denied/Granted/Pending)	✅	Enum with iota
`Guard` struct	✅	workingDir, blockedPaths, gitignore
`NewGuard()` constructor	✅	Injects working dir + GitAwareness
`CheckPath()` permission matrix	✅	read+inDir=Granted, write=Pending, outside=Pending
`IsBlocked()`	✅	Checks gitignore + sensitive paths + dotfiles
`ResolvePath()`	✅	Handles relative and absolute paths
`IsInWorkingDir()`	✅
Blocked paths list	✅	`/etc`, `/usr`, `/bin`, etc.
Dotfile protection	✅	Blocks `~/.<anything>`
Unit tests	✅	8 test functions

Deviation from plan: The plan specified blocking path traversal (../) as PermissionDenied, but the implementation treats it as PermissionPending (asks user). The test explicitly documents this choice. This is arguably more flexible — the user can approve access to sibling directories.

[!NOTE] The plan listed ~/.ssh, ~/.aws as explicitly blocked sensitive paths. The implementation takes a broader approach: any path starting with ~/.<something> is blocked. This is stricter than the plan and a reasonable security choice.

Task 4: GitAwareness ✅ Complete¶

Requirement	Status	Notes
`GitAwareness` struct	✅	Uses `go-git` gitignore package
`LoadGitignore()`	✅	Parses single `.gitignore` file
`LoadGitignoreRecursive()`	✅	Walks directories for nested `.gitignore`
`IsIgnored()`	✅	Checks all loaded patterns
`FilterPaths()`	✅	Batch filter operation
Comments & blank lines	✅	Handled in parser
Glob patterns	✅	Via `go-git` library
Unit tests	✅	5 test functions including recursive loading

What's missing from the plan: - ❌ Global gitignore (~/.gitignore_global) — not implemented - ❌ Caching of IsIgnored results — no cache layer - ❌ Negation patterns (!important.log) — no test for this (the library may support it, but it's untested) - ❌ Interface extraction — the plan specifies GitAwareness as an interface, but the implementation is a concrete struct. Guard depends on *GitAwareness directly, not an interface.

Task 5: Basic CLI ✅ Complete¶

Design doc: output-5_basic-cli.md

Requirement	Status	Notes
`keen` starts REPL	✅	Root command runs REPL
`keen --version`	✅	Via cobra's built-in version
Interactive setup (first run)	✅	Provider → API Key → Model flow
Provider registry (embedded YAML)	✅	`configs/providers/registry.yaml`
`huh` for interactive prompts	✅	Select + password input
Config saved after setup	✅	To `~/.keen/configs.json`
REPL with styled output	✅	lipgloss styling, welcome banner
Signal handling (Ctrl+C)	✅	Graceful shutdown
`/exit` command	✅
No CLI flags (all via prompts)	✅

The REPL stub: The REPL currently echoes input back — it has no command routing, no /help, /plan, /work, /model, /clear, or /add commands. This is expected for a phase 1 stub.

No tests for CLI/setup/providers:

? github.com/user/keen-cli/cmd/agent       [no test files]
? github.com/user/keen-cli/configs/providers [no test files]
? github.com/user/keen-cli/internal/cli      [no test files]

Task 6: Structured Logging ✅ Complete¶

Requirement	Status	Notes
`log/slog` usage	✅	Standard library structured logging
Log level config	✅	Via `KEEN_LOG_LEVEL` env var
Logging in components	✅	Used in config loader, guard, config resolution

Deviation: The plan mentioned a dedicated internal/logger/ package. Instead, logging is configured directly in main.go using slog.SetDefault(). This is simpler and perfectly fine for the current stage.

Overall Scorecard¶

Task	Plan Status	Quality	Tests
1. Project Structure	✅ Complete	Good	N/A
2. Config System	✅ Complete	Strong	13 tests ✅
3. FileGuard	✅ Complete	Strong	8 tests ✅
4. GitAwareness	⚠️ Mostly Complete	Good (missing interface, cache, global gitignore)	5 tests ✅
5. Basic CLI	✅ Complete	Good	❌ No tests
6. Logging	✅ Complete	Simple but effective	N/A

Summary¶

Phase 1 is ~90% complete. All six tasks have working implementations. The project builds, tests pass, and the binary runs. The remaining gaps are:

GitAwareness interface — not extracted (breaks RFC design)
No caching in GitAwareness (plan specified it)
No global gitignore support
No tests for internal/cli/, configs/providers/, or cmd/agent/
prompt.go deletion — mentioned in the basic CLI plan as something to remove, but it doesn't exist (already done or never created)
REPL is a stub — only echoes input, no command routing (expected for phase 1)

The code quality is clean, idiomatic Go. No comments clutter the code. Dependencies are minimal and well-chosen. The security model (FileGuard + GitAwareness integration) is solid.
