Apex Spec Workflow
A specification-driven workflow system for AI-assisted development that breaks
large projects into manageable 2-4 hour sessions with 12-25 tasks each.
Core Philosophy
1 session = 1 spec = 2-4 hours (12-25 tasks)
Break large projects into manageable, well-scoped implementation sessions that
fit within AI context windows and human attention spans.
A collection of sessions is a phase. A collection of phases is a mature/late
technical PRD.
Session Scope Rules
Hard Limits (Reject if Exceeded)
| Limit | Value |
|---|
| Maximum tasks | 25 |
| Maximum duration | 4 hours |
| Objectives | Single clear objective |
Ideal Targets
| Target | Value |
|---|
| Task count | 12-25 (sweet spot: 20) |
| Duration | 2-3 hours |
| Focus | Stable/late MVP |
Command Structure
The skill exposes 24 commands total: 14 staged workflow commands and 10 utility
commands. The staged workflow drives the spec lifecycle; utility commands are
listed separately and run outside the session workflow.
Autonomous Command Contract
Every command runs autonomously. Commands must not ask questions, request
approval, wait for feedback, or insert an interactive review stop into the
workflow. When information is incomplete, choose the safest evidence-backed
default, record the assumption, and continue. When an external requirement such
as credentials, sudo access, billing, or a third-party dashboard action makes
progress impossible, stop after preserving all completed work and report the
blocker as a fact; do not ask for a decision.
Every command response must end with an explicit handoff that another agent can
follow without interpretation:
Summary:
- [facts about what changed or why no change was made]
Next command: `command-name` OR `none`
Reason: [why that command is the correct next workflow step]
Use none only when the project is complete or the command is a utility that
does not participate in the staged workflow.
The 14-Command Workflow
The workflow has 3 distinct stages:
Stage 1: INITIALIZATION (One-Time Setup)
initspec -> Set up spec system in project
|
v
createprd -> Generate PRD from requirements doc (optional)
|
v
createuxprd -> Generate UX PRD from design docs (optional)
|
v
phasebuild -> Create first phase structure (session stubs)
Stage 2: SESSIONS WORKFLOW (Repeat Until Phase Complete)
plansession -> Analyze project, create spec + task checklist
|
v
implement -> AI-led task-by-task implementation
|
v
creview -> Review and repair all uncommitted changes
|
v
validate -> Verify session completeness
|
v
updateprd -> Sync PRD, mark session complete
|
+-------------> Loop back to plansession
until ALL phase sessions complete
After a successful plansession run that creates the session spec and task checklist, the next workflow command is always implement.
After a successful implement run, the next workflow command is always
creview. After a successful creview run, the next workflow command is
validate.
After a successful updateprd run, the next workflow command has two paths: return to plansession if the phase still has unfinished sessions; otherwise exit the session loop and begin Phase Transition at audit.
Stage 3: PHASE TRANSITION (After All Previous Phase Sessions Are Complete)
audit -> Local dev tooling (formatter, linter, types, tests)
|
v
pipeline -> CI/CD workflows (quality, build, security)
|
v
infra -> Production infrastructure (health, security, deploy)
|
v
carryforward -> Capture lessons learned
|
v
documents -> Audit and update documentation
|
v
phasebuild -> Create next phase structure
|
v
-> Return to Stage 2 for new phase
carryforward does not jump directly to plansession. The usual handoff is
carryforward -> documents -> phasebuild; however, run phasebuild only if
PRD.md still defines another unfinished phase. If PRD.md has no remaining
phase, the workflow ends after documents and the project is complete.
Utility Commands (Safe at Any Time)
These 10 commands are not part of the required staged workflow. They run outside
the session workflow and can be used for support tasks at any time:
| Command | Purpose |
|---|
| copush | Pull, version-bump, commit all changes, push to origin |
| sculpt-ui | Guide AI-led creation of distinctive frontend interfaces |
| seshsplit | Insert or refresh a session split plan inside a text or Markdown plan file |
| dockbuild | Quick Docker Compose build and start |
| dockcleanbuild | Clean Docker environment and rebuild from scratch |
| up2imp | Audit upstream changes and curate implementation list |
| qimpl | Context-aware autonomous implementation session |
| qfrontdev | Autonomous frontend implementation session |
| qbackenddev | Autonomous backend/infrastructure development session |
| pullndoc | Git pull upstream repo and document imported changes |

Monorepo Support
The system auto-detects monorepo structures. Single .spec_system/ at the
repo root. Sessions reference their target package in metadata (spec.md
header and state.json), not in directory names. Sessions interleave across
packages within a phase.
Scripts
Project analysis scripts provide deterministic state facts and environment
verification. Scripts are copied to .spec_system/scripts/ during
initialization (via the initspec workflow step).
Script Locations
Scripts can be found in two places. Local scripts take precedence:
- Local (per-project):
.spec_system/scripts/ -- copied during init
- Skill directory:
scripts/ -- bundled with this skill
Available Scripts
| Script | Purpose | Usage |
|---|
analyze-project.sh | Deterministic project state | bash .spec_system/scripts/analyze-project.sh --json |
check-prereqs.sh | Environment and tool verification | bash .spec_system/scripts/check-prereqs.sh --json --env |
common.sh | Shared functions (sourced by other scripts) | Sourced automatically |
Local-First Resolution Pattern
Commands that need scripts should check for local copies first:
if [ -d ".spec_system/scripts" ]; then
bash .spec_system/scripts/analyze-project.sh --json
else
bash scripts/analyze-project.sh --json
fi
Task Design
Task Format
- [ ] TNNN [SNNMM] [P] Action verb + what + where (`path/to/file`)
Components:
TNNN: Sequential task ID (T001, T002, ...)[SNNMM]: Session reference (S0103 = Phase 01, Session 03)[P]: Optional parallelization marker- Description: Action verb + clear description
- Path: File being created or modified
ASCII Encoding (Non-Negotiable)
All files must use ASCII-only characters (code points 0-127):
- NO Unicode characters, emoji, smart quotes, or em-dashes
- Use straight quotes (" ') and hyphens (-) only
- Unix LF line endings (no CRLF)
