gsd-tools skill
Central utility skill for GSD operations. Provides config parsing, slug generation, timestamps, path operations, and orchestrates calls to other specialized skills. Acts as the unified entry point that the original gsd-tools.cjs provided via its lib/ modules (commands, config, core, init).

Install the gsd-tools skill
A skill is a folder. Copy it into your agent's skills folder and the agent loads it when the task matches its description.
git clone --depth 1 https://github.com/a5c-ai/babysitter.git /tmp/babysitter mkdir -p ~/.claude/skills cp -r /tmp/babysitter/library/methodologies/gsd/skills/gsd-tools ~/.claude/skills/gsd-tools
In the Claude apps, zip the folder and upload it from the Skills settings. The folder on GitHub
The instructions your agent would load
SKILL.md as published, without the frontmatter. Read it on GitHub
- Load and manage .planning/config.json configuration
- Generate deterministic slugs from descriptions (kebab-case, deduplication)
- Format timestamps for GSD artifact headers and frontmatter
- Resolve paths within the .planning/ directory structure
- Parse and normalize phase numbers (integer and decimal)
- Manage sequential quick task numbering in .planning/quick/
- Initialize and validate .planning/ directory structure
- Detect project state (new project, existing project, mid-phase, etc.)
Capabilities
1. Configuration Loading
Load and parse .planning/config.json with defaults:
{
"profile": "balanced",
"autoCommit": true,
"autoVerify": true,
"planCheckerEnabled": true,
"maxPlanRevisions": 2,
"waveParallelization": true,
"contextMonitor": true,
"contextWarningThreshold": 70,
"contextCriticalThreshold": 85,
"summaryVariant": "standard",
"tddEnabled": false,
"questioningDepth": "adaptive"
}Read config:
cat .planning/config.jsonIf config does not exist, create with defaults. Merge user overrides with defaults (user values take precedence).
2. Slug Generation
Generate kebab-case slugs from descriptions:
Input: "Add user authentication with OAuth2"
Output: "add-user-authentication-with-oauth2"
Input: "Fix bug #123 in payment processing"
Output: "fix-bug-123-in-payment-processing"Rules:
- Lowercase all characters
- Replace spaces and special characters with hyphens
- Remove consecutive hyphens
- Trim leading/trailing hyphens
- Maximum 60 characters (truncate at word boundary)
- Check for duplicates in target directory, append -2, -3 if needed
3. Timestamp Formatting
Format timestamps for GSD artifacts:
Header: "2026-03-02T14:30:00Z"
Frontmatter: "2026-03-02"
Filename: "20260302-143000"
Display: "Mar 2, 2026 2:30 PM"4. Path Operations
Resolve paths within .planning/ structure:
Phase directory: .planning/phase-{N}/
Plan file: .planning/phase-{N}/PLAN-{M}.md
Summary file: .planning/phase-{N}/SUMMARY.md
Quick task: .planning/quick/{NNN}-{slug}/
Debug session: .planning/debug/{slug}.md
Codebase docs: .planning/codebase/
Research docs: .planning/research/
Milestone archive: milestones/v{X}.{Y}/5. Phase Number Parsing
Parse integer and decimal phase numbers:
"72" -> { major: 72, minor: null, display: "72" }
"72.1" -> { major: 72, minor: 1, display: "72.1" }
"72.2" -> { major: 72, minor: 2, display: "72.2" }Decimal phases are inserted phases (e.g., urgent work between phase 72 and 73).
6. Quick Task Numbering
Sequential numbering for quick tasks:
.planning/quick/001-fix-login-bug/
.planning/quick/002-add-rate-limiting/
.planning/quick/003-update-readme/Scan existing directories, find highest number, increment by 1. Zero-pad to 3 digits.
7. Planning Directory Initialization
Ensure .planning/ directory exists with required structure:
.planning/
config.json
PROJECT.md (if new-project has run)
REQUIREMENTS.md (if new-project has run)
ROADMAP.md (if new-project has run)
STATE.md (always present after init)
quick/ (created on demand)
debug/ (created on demand)
codebase/ (created on demand)
research/ (created on demand)8. Project State Detection
Detect current project state for routing:
const states = {
NO_PROJECT: "No .planning/ directory or no PROJECT.md",
INITIALIZED: ".planning/ exists with PROJECT.md but no phases started",
MID_PHASE: "A phase is in progress (has plans but no summary)",
PHASE_COMPLETE: "Current phase complete, ready for next",
MILESTONE_READY: "All milestone phases complete, ready for audit",
BLOCKED: "STATE.md has active blockers"
};Tool Use Instructions
Reading Configuration
- Use Read to load .planning/config.json
- Parse JSON and merge with defaults
- Return merged configuration object
Generating Slugs
- Accept description string as input
- Apply slug transformation rules
- Use Glob to check for duplicates in target directory
- Append deduplication suffix if needed
- Return final slug
Initializing Planning Directory
- Use Bash to create directory structure with mkdir -p
- Use Write to create config.json with defaults if missing
- Use Read + Glob to detect existing state
- Return initialization status
Process Integration
This skill is used by all GSD processes as the first initialization step:
- new-project.js - Initialize .planning/, create config
- plan-phase.js - Resolve phase paths, load config for planner settings
- execute-phase.js - Load config for executor settings, resolve task paths
- quick.js - Generate quick task number and slug, resolve quick task path
- debug.js - Generate debug session slug, resolve debug path
- progress.js - Detect project state, load config
- complete-milestone.js - Resolve milestone archive path
- add-tests.js - Resolve phase paths for test generation
- research-phase.js - Resolve research output paths
Output Format
{
"operation": "init|config|slug|path|state",
"status": "success|error",
"result": {
"config": {},
"slug": "generated-slug",
"path": "/resolved/path",
"state": "NO_PROJECT|INITIALIZED|MID_PHASE|..."
},
"metadata": {
"planningDir": ".planning/",
"configPath": ".planning/config.json",
"timestamp": "2026-03-02T14:30:00Z"
}
}Configuration
Error Handling
Constraints
- Never modify files outside .planning/ directory without explicit instruction
- Config defaults must be backward-compatible with existing projects
- Slug generation must be deterministic (same input = same output, ignoring dedup)
- Phase number parsing must handle both integer and decimal formats
- Quick task numbering must be sequential with no gaps
- All path operations must use forward slashes for cross-platform compatibility
