Content Calendar Skill

Manage editorial content through 6 pipeline stages: Ideas, Outlined, Drafted, Editing, Ready, Published. All pipeline state lives in a single content-calendar.md file -- this is the sole source of truth, never store state elsewhere.

Instructions

Phase 1: READ PIPELINE

Goal: Load and validate the current calendar state before any mutation.

Memory of pipeline state is unreliable -- always read the actual file, because assumed state leads to overwrites of changes made by other processes or manual edits.

1. Read content-calendar.md from the project root. Also read the repository CLAUDE.md to ensure compliance with project-specific rules.
2. Parse pipeline sections -- extract entries from Ideas, Outlined, Drafted, Editing, Ready, Published, and Historical sections.
3. Validate file structure -- all required sections exist, counts match actual entries.

Gate: Calendar file loaded and parsed successfully. All sections accounted for. Proceed only when gate passes.

Phase 2: EXECUTE OPERATION

Goal: Perform the requested pipeline operation -- only the operation requested. No speculative reorganization, no "while I'm here" reformatting of unrelated sections.

Operation: View Pipeline

1. Count entries in each stage
2. Identify upcoming scheduled content (next 14 days)
3. Identify in-progress content (Outlined, Drafted, Editing) -- emphasize these as actively being worked on
4. Gather recent publications (last 30 days)
5. Display dashboard with progress indicators
6. Optionally flag content stuck in a stage for 14+ days or show velocity metrics if requested

Operation: Add Idea

1. Validate topic name is non-empty
2. Search all sections for duplicate titles (case-insensitive); warn if a matching title exists because duplicates clutter the pipeline
3. Append - [ ] [Topic name] to Ideas section
4. Update pipeline count in overview table

Operation: Move Content

Content moves forward through defined stages only -- each transition represents real editorial work completed, so skipping stages misrepresents progress.

1. Find topic in its current section (search all sections)
2. Validate target stage is the next sequential stage:
   • Ideas -> Outlined -> Drafted -> Editing -> Ready -> Published
3. Remove entry from current section
4. Add to target section with timestamp metadata (every transition records YYYY-MM-DD):
   • outlined: (outline: YYYY-MM-DD)
   • drafted: (draft: YYYY-MM-DD)
   • editing: (editing: YYYY-MM-DD)
   • ready: (ready: YYYY-MM-DD) -- prompt for a scheduled publication date because content without a date clogs the pipeline and goes stale
   • published: (published: YYYY-MM-DD)
5. Update pipeline counts

Operation: Schedule Content

1. Find topic (must be in Ready section)
2. Validate date is today or future
3. Update or add Scheduled: YYYY-MM-DD to entry
4. Update file

Operation: Archive Published

Archive prevents the Published section from growing unbounded, which makes the dashboard cluttered and counts misleading.

1. Find Published entries older than current month
2. Move to appropriate ### YYYY-MM section in Historical
3. Update pipeline counts

Gate: Operation executed with all validations passing. Proceed only when gate passes.

Phase 3: WRITE AND CONFIRM

Goal: Persist changes and verify the write succeeded.

Read the full calendar file before writing -- never truncate or lose existing entries.

1. Write the updated calendar file back to disk.
2. Re-read the file and verify the change is present. Looking correct is not the same as being correct; the re-read proves it.
3. Display confirmation with relevant dashboard section showing the change.

Gate: File written, re-read confirms changes persisted. Operation complete.

Error Handling

Error: "Calendar file not found"

Cause: content-calendar.md does not exist in the project Solution:

1. Create initial calendar file with all empty sections and overview table
2. Confirm file creation to user
3. Proceed with requested operation

Error: "Topic not found in pipeline"

Cause: User referenced a topic name that does not match any entry Solution:

1. Search all sections for partial matches (case-insensitive)
2. Suggest closest matches if available
3. Show current pipeline state so user can identify the correct title

Error: "Invalid stage transition"

Cause: User attempted to skip a stage (e.g., Ideas directly to Ready) Solution:

1. Explain the required stage sequence
2. Show the topic's current stage and the next valid stage
3. Ask user to confirm sequential move or move to adjacent stage
