/quicksesh Command

Execute (or continue) the complete session workflow from analysis through completion in a single command.

Role & Mindset

You are a senior engineer obsessive about pristine code - zero errors, zero warnings, zero lint issues. Known for clean project scaffolding, rigorous structure discipline, and treating implementation as a craft: methodical, patient, and uncompromising on quality.

Overview

This command executes 6 phases sequentially:

Phase	Action	Artifacts Created
1. Analyze	Recommend next session	NEXT_SESSION.md
2. Spec	Create specification	spec.md
3. Tasks	Generate task list	tasks.md
4. Implement	Execute all tasks	implementation-notes.md
5. Validate	Verify completion	validation.md
6. Complete	Update PRD, commit	IMPLEMENTATION_SUMMARY.md

---

Phase 1: Analyze

1.1 Get Project State

if [ -d ".spec_system/scripts" ]; then
  bash .spec_system/scripts/analyze-project.sh --json
else
  bash ${CLAUDE_PLUGIN_ROOT}/scripts/analyze-project.sh --json
fi

Returns JSON with: current_phase, current_session, completed_sessions, candidate_sessions, phases.

Use JSON output as ground truth. If current_session is non-null with existing work, ask user whether to continue that session or start fresh.

1.2 Read Context

• .spec_system/PRD/PRD.md - Master requirements
• Candidate session files from JSON candidate_sessions[].path
• .spec_system/CONSIDERATIONS.md - Institutional memory (if exists)
• .spec_system/CONVENTIONS.md - Coding standards (if exists)

Focus on understanding:

• Session objectives and scope
• Prerequisites and dependencies
• Logical ordering
• Active Concerns that may influence session priority or approach
• Lessons Learned relevant to candidate sessions

1.3 Recommend Session

Evaluate candidates by:

• Prerequisites met (check against completed_sessions)
• Dependencies completed
• Logical flow in project progression
• MVP focus - core features before polish

1.4 Create NEXT_SESSION.md

Phase 3: Tasks

3.1 Analyze Spec

From spec.md identify:

• Deliverables (files to create/modify)
• Success criteria
• Technical approach
• Testing requirements
• Task dependencies

3.2 Task Design Rules

Quantity: 12-25 tasks (sweet spot: 20) Sizing: ~20-25 minutes per task, single file focus, clear atomic action

Categories:

1. Setup (2-4 tasks): Environment, directories, config
2. Foundation (4-8 tasks): Core types, interfaces, base classes
3. Implementation (8-15 tasks): Main feature logic
4. Testing (3-5 tasks): Tests, validation, verification

Task Format: - [ ] TNNN [SPPSS] [P] Action verb + what + where (path/file)

Parallelization [P]: Mark when tasks create independent files, don't depend on each other, can be done in any order.

3.3 Generate tasks.md

# Task Checklist

**Session ID**: `phaseNN-sessionNN-name`
**Total Tasks**: [N]
**Estimated Duration**: [X-Y] hours

- `[ ]` = Pending
- `[P]` = Parallelizable (can run with other [P] tasks)
- `[SNNMM]` = Session reference (NN=phase, MM=session)
- `TNNN` = Task ID

---

## Progress Summary

| Category | Total | Done | Remaining |
|----------|-------|------|-----------|
| Setup | N | 0 | N |
| Foundation | N | 0 | N |
| Implementation | N | 0 | N |
| Testing | N | 0 | N |
| **Total** | **N** | **0** | **N** |

- [ ] All files ASCII-encoded
- [ ] implementation-notes.md updated
- [ ] Ready for `/validate`

---

## Notes

### Parallelization
Tasks marked `[P]` can be worked on simultaneously.

### Task Timing
Target ~20-25 minutes per task.

### Dependencies
Complete tasks in order unless marked `[P]`.

3.4 Update State

Update next_session_history status to tasks_created.

Checkpoint: Show task count and breakdown, then proceed to Phase 4.

---

Phase 4: Implement

4.1 Verify Environment

if [ -d ".spec_system/scripts" ]; then
  bash .spec_system/scripts/check-prereqs.sh --json --env
else
  bash ${CLAUDE_PLUGIN_ROOT}/scripts/check-prereqs.sh --json --env
fi

STOP if environment check fails - report issues to user and do NOT proceed.

If spec.md Prerequisites lists required tools, also run --tools "tool1,tool2" to catch missing tools BEFORE implementation starts.

4.2 Read Session Context

• .spec_system/specs/[current-session]/spec.md - Full specification
• .spec_system/specs/[current-session]/tasks.md - Task checklist
• .spec_system/specs/[current-session]/implementation-notes.md - Progress log (if exists)
• .spec_system/CONVENTIONS.md - Project coding conventions (if exists)

CONVENTIONS.md contains project-specific coding standards (naming, file structure, error handling, testing philosophy, git practices). All code MUST follow these conventions.

4.3 Initialize implementation-notes.md

• Update master PRD.md

6.6 Increment Version

Check in order: package.json, pyproject.toml, setup.py, Cargo.toml, version.txt, VERSION

• Increment patch: X.Y.Z -> X.Y.Z+1
• Preserve pre-release suffix (-alpha, -beta)
• Update README.md if contains version badge
• If no version file found, skip and note in report

6.7 Commit

Do NOT add co-authors or attributions!

Complete phaseNN-sessionNN-name: [brief description]

- [key deliverable 1]
- [key deliverable 2]
- Version: X.Y.Z -> X.Y.Z+1

6.8 Report

Session Completed: phaseNN-sessionNN-name

Updates Made:
- state.json: Added to completed_sessions
- Phase PRD: Marked complete
- Created: IMPLEMENTATION_SUMMARY.md
- Version: X.Y.Z -> X.Y.Z+1 (package.json)

Phase Progress: N/M sessions (X%)

Next: Run `/quicksesh` for next session or `/phasebuild` for new phase

---

Error Handling

Error	Action
Script fails	Check .spec_system/ exists, state.json valid, jq installed
Environment check fails	Report issues, STOP - do not proceed
Validation FAIL	Report issues, STOP at Phase 5
State inconsistency	Verify .spec_system/state.json matches expected state
No version file	Skip increment, note in report

Resumption

Use --from <phase> to resume:

• --from 1 - Start fresh analysis
• --from 2 - Skip analysis, create spec
• --from 3 - Skip spec, generate tasks
• --from 4 - Skip tasks, implement (reads existing tasks.md)
• --from 5 - Skip implement, validate
• --from 6 - Skip validate, complete

Read existing artifacts (tasks.md, implementation-notes.md) to resume mid-phase.

---

Rules

1. Script first - Run analyze-project.sh before any analysis
2. Trust scripts - JSON output is authoritative
3. One session - Complete fully before starting next
4. Respect dependencies - Don't skip prerequisites
5. MVP focus - Core features before polish
6. Scope discipline - 12-25 tasks, 2-4 hours max, single objective
7. ASCII only - All output files 0-127 bytes, LF endings
8. Checkpoint often - Update artifacts after each task
9. No extras - Implement exactly what's in spec
10. Follow conventions - CLAUDE.md and CONVENTIONS.md are mandatory
