Nav Task

Navigator Task Manager Skill

Create and manage task documentation - implementation plans that capture what was built, how, and why.

When to Invoke

Invoke this skill when the user:

• Says "document this feature", "archive this task"
• Says "create task doc for...", "document what I built"
• Completes a feature and mentions "done", "finished", "complete"
• Starts new feature and says "create implementation plan"

DO NOT invoke if:

• User is asking about existing tasks (use Read, not creation)
• Creating SOPs (that's nav-sop skill)
• Updating system docs (different skill)

Execution Steps

Step 1: Determine Task ID

If user provided task ID (e.g., "TASK-01", "GH-123"):

• Use their ID directly

If no ID provided, run the generator — it reads task_id_source from .agent/.nav-config.json (default local):

PLUGIN_DIR="${CLAUDE_PLUGIN_ROOT:-$(cat "${NAVIGATOR_CONFIG_HOME:-${XDG_CONFIG_HOME:-$HOME/.config}/navigator}/plugin-root" 2>/dev/null)}"
[ -d "$PLUGIN_DIR/skills" ] || PLUGIN_DIR="$HOME/.claude/plugins/marketplaces/navigator-marketplace"
python3 "$PLUGIN_DIR/skills/nav-task/functions/task_id_generator.py" \
  --title "{feature name}" --body "{one-line summary}" --json

• task_id_source: local (solo repos) — next sequential {task_prefix}-NN from .agent/tasks/ (last is TASK-05 → TASK-06). --title is ignored.
• task_id_source: github (team repos, GH-32) — creates the GitHub issue first via gh issue create and returns GH-<n>; the doc is .agent/tasks/GH-<n>-{slug}.md. Issue numbers are allocated by GitHub, so two contributors branching at once can never mint the same ID, and Pilot already addresses tasks as GH-<n>. Add --label pilot (or any label) when the issue should be picked up. A failing gh (no auth, no network) is an error — do not fall back to a local number; tell the user and stop.
• Existing TASK-NN docs keep working either way; the index, graph sync and session-start listing accept any PREFIX-<n> filename.
• In the doc template below, TASK-{XX} stands for whichever ID came back.

Step 2: Determine Action (Create vs Archive)

Creating new task (starting feature):

User: "Create task doc for OAuth implementation"
→ Action: CREATE
→ Generate empty implementation plan template

Archiving completed task (feature done):

User: "Document this OAuth feature I just built"
→ Action: ARCHIVE
→ Generate implementation plan from conversation

Step 2.5: Recall Prior Knowledge (CREATE flow only, v6.17.0+)

Before writing the plan, query the knowledge graph for memories relevant to this feature — pitfalls and patterns the project has already paid for:

PLUGIN_DIR="${CLAUDE_PLUGIN_ROOT:-$(cat "${NAVIGATOR_CONFIG_HOME:-${XDG_CONFIG_HOME:-$HOME/.config}/navigator}/plugin-root" 2>/dev/null)}"
[ -d "$PLUGIN_DIR/skills" ] || PLUGIN_DIR="$HOME/.claude/plugins/marketplaces/navigator-marketplace"

if [ -f ".agent/knowledge/graph.json" ]; then
  python3 "$PLUGIN_DIR/skills/nav-graph/functions/memory_recall.py" \
    --concepts "{comma-separated concepts inferred from the feature description}" \
    --format markdown --limit 5
fi

• Infer concepts from the feature description using the same keyword families as task_to_graph.extract_concepts_from_task (auth, database, api, frontend, testing, …) — alias resolution absorbs abbreviations.
• Empty output → skip silently. Do not add the section; do not mention the absence.
• Non-empty output → include it as the ## Known Pitfalls & Patterns section in the template below, and reflect each recalled pitfall in the Implementation phases (a recalled pitfall that doesn't change the plan wasn't really factored in).

Step 3A: Create New Task (If Starting Feature)

Generate task document from template:

# TASK-{XX}: {Feature Name}

**Status**: 🚧 In Progress
**Created**: {YYYY-MM-DD}
**Assignee**: {from PM tool or "Manual"}

---

## Context

**Problem**:
[What problem does this solve?]

**Goal**:
[What are we building?]

---

## Known Pitfalls & Patterns

<!-- From knowledge graph (Step 2.5). OMIT this section entirely if recall
     returned nothing. Each recalled pitfall must be reflected in the
     Implementation phases below. -->

- **PITFALL** (90%, mem-XXX): [recalled summary]

---

## Acceptance Criteria

Concrete, checkable outcomes — written so anyone (human or AI) can verify them.

- [ ] [Specific, observable outcome]
- [ ] [Another outcome]
- [ ] [Edge case handled]

---

## Implementation

### Phase 1: {Name}
**Goal**: [What this phase accomplishes]

**Tasks**:
- [ ] [Specific task]
- [ ] [Another task]

**Files**:
- `path/to/file.ts` - [Purpose]

### Phase 2: {Name}
...

---

## Out of Scope

Explicit non-goals — what this task deliberately does not address.

- [What's deferred to a future task]
- [Adjacent change being avoided]

---

## Technical Decisions

| Decision | Options Considered | Chosen | Reasoning |
|----------|-------------------|--------|-----------|
| [What] | [Option A, B, C] | [Chosen] | [Why] |

---

## Verify

Run these commands to validate the implementation:

```bash
# Run tests
[test command for this feature]

# Type check
[type check command]

# Build
[build command]

Done

Observable outcomes that prove completion:

• [Specific file/API exists and exports expected interface]
• [Tests pass - specify count or coverage target]
• [Build succeeds without errors]
• [User-observable behavior works as specified]

Refs

• [Source plan / design doc / parent issue]
• [Related ticket]

Notes

[Any additional context, links, references]

Last Updated: {YYYY-MM-DD}

Save to: `.agent/tasks/TASK-{XX}-{slug}.md`

### Step 3B: Archive Completed Task (If Feature Done)

Generate task document from conversation:

1. **Analyze conversation** (last 30-50 messages):
   - What was built?
   - How was it implemented?
   - What decisions were made?
   - What files were modified?

2. **Generate implementation plan**:

```markdown
# TASK-{XX}: {Feature Name}

**Status**: ✅ Completed
**Created**: {YYYY-MM-DD}
**Completed**: {YYYY-MM-DD}

---

## What Was Built

[1-2 paragraph summary of the feature]

---

## Implementation

### Phase 1: {Actual phase completed}
**Completed**: {Date}

**Changes**:
- Created `src/auth/oauth.ts` - OAuth provider integration
- Modified `src/routes/auth.ts` - Added login/logout endpoints
- Updated `src/config/passport.ts` - Passport configuration

**Key Code**:
```typescript
// Example of key implementation
export const oauthLogin = async (req, res) => {
  // Implementation details
};

Phase 2: {Next phase}

...

• src/config/passport.ts (created) - Passport setup
• tests/auth.test.ts (created) - Auth tests
• README.md (updated) - OAuth setup instructions
