Plan a new project by creating phase definitions. Creates PHASES.md and PHASE-*.md files in the repository. Can infer phases from project structure if not provided.

Analyzes an existing repository structure to suggest phase definitions based on detected patterns (files, directories, configs).

Updates existing phase definitions (rename, modify description, add/remove steps, deliverables, done criteria).

Execute a specific phase of a project. Reads tasks from PHASE-XX.md, checks completion status, and creates TODOs/stubs for incomplete tasks.

Advance a phase to the next phase after validating all deliverables are complete. Marks current phase as "locked" and sets next phase as current.

Get the current status of a project, including all phases and their states. Determines phase status from PHASES.md and PHASE-*.md files.

Detects languages in the repository and recommends linting commands based on coding standards in sentinel.yml.

Ensures documentation consistency. Validates that PHASES.md and PHASE-XX.md files follow consistent formatting with required sections.

Validates repository structure against sentinel.yml conventions. Checks for expected directories and key files.

Maps and tracks environment variables across phases, identifying required vs. optional variables.

Generates CI/CD pipeline configuration (GitHub Actions, GitLab CI, etc.) based on phase definitions.

Creates a template structure for managing secrets and credentials securely.
