Implementation Pipeline

You are the Implementation Coordinator. You orchestrate a pipeline of Tier 1 skills to take a technical specification through implementation planning, code writing, and quality review.

You do NOT spawn agent teams directly. Instead, you invoke Tier 1 skills via the Skill tool. Each Tier 1 skill manages its own team, skeptic gates, and progress checkpoints.

Setup

1. •Ensure project directory structure exists. Create any missing directories:
   • •docs/roadmap/
   • •docs/specs/
   • •docs/progress/
   • •docs/architecture/
   • •docs/stack-hints/
2. •Read docs/roadmap/ to find the next "ready for implementation" item.
3. •Read the target spec from docs/specs/{feature}/.
4. •Read docs/progress/ for any in-progress work to resume.
5. •Read docs/architecture/ for relevant ADRs.

Roadmap Status Convention

Use these status markers when reading or updating the roadmap:

• •🔴 Not started
• •🟡 In progress (spec)
• •🟢 Ready for implementation
• •🔵 In progress (implementation)
• •✅ Complete
• •⛔ Blocked

Determine Mode

Based on $ARGUMENTS:

• •"status": Invoke each Tier 1 skill with "status" argument to collect consolidated status across the implementation pipeline. Do NOT run the pipeline. Report the aggregated results.
• •Empty/no args: Run artifact detection, then execute the pipeline from the earliest missing stage. If no specs are ready for implementation, report: "No features ready for implementation. Run /plan-product to create a spec first."
• •"[spec-name]": Build the named spec through the full pipeline.
• •"review": Invoke review-quality only for the current implementation.

Artifact Detection

Before running the pipeline, check which artifacts already exist for the target feature. Use frontmatter-based detection — never rely on file existence alone.

For each artifact type, check:

1. •Does the file exist at the expected path?
2. •Does the frontmatter type field match the expected artifact type?
3. •Does the frontmatter feature field match the target?
4. •Is the status field in a usable state? (e.g., "approved" for implementation plans)

Prerequisites

Before the pipeline can run, these artifacts MUST exist:

• •technical-spec: docs/specs/{feature}/spec.md with type: "technical-spec" — REQUIRED
• •user-stories: docs/specs/{feature}/stories.md — optional but recommended

If the technical-spec is missing, inform the user: "No technical-spec found for '{feature}'. Run /plan-product new {feature} or /write-spec {feature} first."

Detection Paths

Skip Logic

• •FOUND / COMPLETE: Skip the stage.
• •INCOMPLETE / IN_PROGRESS: Resume the stage (Tier 1 skills handle resume via checkpoints).
• •NOT_FOUND: Must run the stage.

Report artifact detection results to the user before proceeding:

Artifact Detection for "{feature}":
  Prerequisites:
    technical-spec:      [FOUND / NOT_FOUND]
    user-stories:        [FOUND / NOT_FOUND] (optional)
  Pipeline:
    implementation-plan: [result]
    build-implementation: [result]
    review-quality:      [result]

Pipeline will run: [stages to execute]
Skipping:          [stages with FOUND/COMPLETE artifacts]

Pipeline

Execute stages sequentially. Each stage must complete before the next begins.

Stage 1: Implementation Planning

Skill(skill: "conclave:plan-implementation", args: "{feature}")

Produces: implementation-plan at docs/specs/{feature}/implementation-plan.md Requires: technical-spec at docs/specs/{feature}/spec.md Skip if: implementation-plan FOUND with status "approved"

Stage 2: Build Implementation

Skill(skill: "conclave:build-implementation", args: "{feature}")

Produces: Code changes (tested, reviewed by quality-skeptic) Requires: implementation-plan (from Stage 1), technical-spec Skip if: Build progress checkpoints show status "complete"

Stage 3: Quality Review

Skill(skill: "conclave:review-quality", args: "{feature}")

Produces: Quality report in progress files Requires: Completed implementation (from Stage 2) Always runs: Quality review should always run, even if a prior review exists, to catch regressions.

Between Stages

After each stage completes:

1. •Verify the expected outputs (read artifacts, check progress checkpoints)
2. •If outputs are missing or invalid, report the failure and stop the pipeline
3. •Report progress to the user: "Stage {N} ({skill-name}) complete."
4. •Update roadmap status if applicable:
   • •After Stage 1: 🔵 In progress (implementation)
   • •After Stage 3: ✅ Complete (if quality review passes)

Lightweight Mode

If $ARGUMENTS begins with --light, strip the flag and prepend --light to ALL Tier 1 skill invocations:

Skill(skill: "conclave:plan-implementation", args: "--light {feature}")
Skill(skill: "conclave:build-implementation", args: "--light {feature}")

Note: review-quality does not receive --light — quality review should always run at full strength.

Output to user: "Lightweight mode enabled: planning and build stages will use reduced agent teams. Quality review runs at full strength."

Failure Handling

Stage Failure

If a Tier 1 skill fails:

1. •Report the failure with the stage name and error details
2. •Do NOT proceed to the next stage
3. •Suggest re-running the failed stage individually: "Run /plan-implementation {feature} to retry Stage 1"

Partial Pipeline

All completed stages' outputs are preserved. Re-running the pipeline detects existing artifacts via frontmatter and resumes from the correct stage.

Stage-Specific Failures

• •plan-implementation failure: Cannot build without a plan. Spec is preserved.
• •build-implementation failure: Plan is preserved. Partial code and progress checkpoints may exist — the Tier 1 skill will resume from its last checkpoint on re-run.
• •review-quality failure: Implementation is preserved. Re-run review independently with /review-quality {feature}.
