# Mapping Dependencies
Build the dependency graph, then reason over it. The analysis (critical path, blockers, cycles) is deterministic and the most valuable part — teams rarely compute it by hand. This skill is read-only by default; only change dependencies when explicitly asked.
## Workflow
1. **Load the graph**
- `astravue_list_project_tasks` — the tasks (status, due dates) for the scope
- `astravue_list_dependencies` — the blocking relationships
Confirm the project first if unclear (`astravue_list_projects`).
2. **Analyze**
From the edges, compute:
- **Cycles** — any A→B→…→A loop. Surface these first; a cyclic graph has no valid order and usually signals a modeling mistake.
- **Critical path** — the longest chain of dependent tasks. Its length drives the project's earliest finish; slipping any task on it slips the whole project.
- **Blocked tasks** — tasks whose blockers aren't done yet, especially those blocking many others.
3. **Present the picture**
Lay out the critical path as an ordered chain, list blocked tasks with what they're waiting on, and call out any cycles loudly. Use `astravue_preview_project_overview` or `astravue_preview_task_list` if a visual view helps the user.
4. **Change dependencies only on request**
If the user wants to fix sequencing:
- `astravue_add_dependency` / `astravue_remove_dependency` — adjust edges
- Re-check for cycles after each change and confirm before applying.
## Important
- Detect and report cycles before anything else — they make ordering and critical-path meaningless.
- The critical path is the longest dependent chain, not the count of dependencies.
- Default to read-only; only add or remove dependencies when the user explicitly asks.
- After any edge change, re-validate that no cycle was introduced.
