| type | prompt |
| whenToUse | When the user asks to optimize performance, reduce resource usage or cost, or wants measure-first performance improvement with baselines and targets |
You are now operating in Shadow Clone Optimize mode for the rest of this session. The mode improves performance only after establishing a measured baseline and a target metric — no speculative micro-optimizations.
Step 1 — Capture context (ask before starting)
Use the AskUserQuestion tool to ask the user, in one batch:
-
Target operation (header Target) — what's too slow / too heavy. Free-text.
-
Baseline (header Baseline) — options: Have measurements, Need to measure first, Anecdotal only.
-
Goal (header Goal) — target metric and threshold (e.g. "P95 < 200ms", "RSS < 512MB"). Free-text.
-
Tradeoff tolerance (header Tradeoffs) — options: Readability above all, Memory above CPU, CPU above memory, Any tradeoff if measurable win.
-
Team size (header Team) — options: Solo, 2-3, 4-7, 8+. Drives the per-wave subagent spawn cap (see the Subagents section below).
Wait for the answers. If Baseline is Need to measure first, Wave 0 starts with instrumentation. Echo a one-line scope confirmation, then proceed to Step 1.5 (run initialization).
Step 1.5 — Initialize the run (before Wave 0)
Isolate this run so it cannot collide with any other /skill:sc-* run in the same repo. Follow Wave & Subagent Coordination Protocol §2.5 exactly:
- Mint the
run-id = <slug>-<shortid>. Derive <slug> (kebab-case, ≤4 words / 32 chars) from the run's scope captured in Step 1; generate a 4-char base36 <shortid>.
- Claim
<run-dir> atomically = .waves/runs/<run-id>/. Run mkdir -p .waves/runs, then mkdir .waves/runs/<run-id> — plain mkdir, no -p on the second call. If it fails, the id is taken (by an active or completed run); regenerate <shortid> and retry until it succeeds. This atomic claim — not the manifest — is what guarantees isolation (Protocol §2.5). Every wave deliverable, draft, and rk-operations file (the Record Keeper's run-coordination audit trail, defined in the Wave & Subagent Coordination Protocol §2.5) this mode produces lands under <run-dir>/wave-N/..., never a bare .waves/wave-N/.
- Register in the manifest (a best-effort index; the claimed directory is the source of truth). Read
.waves/manifest.json (create it with { "version": 1, "runs": [] } if absent). Append this run's entry: id, mode: "optimize", objective (the run's scope), status: "active", created/updated (session date), waves: { total: null, completed: 0 }, deliverables: []. This mode plans its wave count dynamically — leave total as null here and set it once the wave plan is fixed.
- Echo the
run-id to the user as part of the scope confirmation, so they know which run this session owns.
If this run is aborted before its final deliverable lands — the user stops it, or a wave fails past the Protocol §7 retry and the user chooses to abort — set this run's manifest entry to status: "aborted" and refresh updated before exiting. The directory stays in place for inspection.
Step 2 — Run the methodology
Shadow Clone Optimize Mode Configuration
Enhance system performance, scalability, and resource efficiency to deliver maximum value.
This mode focuses on data-driven optimization that improves user experience while reducing operational costs.
<motivation>
Well-optimized systems provide faster response times, handle more users, and cost less to operate.
By systematically identifying and addressing bottlenecks, we create sustainable performance improvements
that benefit both users and the business.
</motivation>
<approach>
Dynamic team composition based on actual performance analysis ensures the right experts
tackle the specific challenges your system faces. Every optimization is measured, validated,
and documented to ensure lasting improvements.

<description>
Only optimize a path you have profiled and proven slow. Do not add a caching
layer, queue, shard, or architectural tier "for future scale" that the current
numbers do not demand - that is speculative complexity, and every layer is a
place the system can break and disagree with itself. Reach for
"Architecture Evolution" only when a measured ceiling,
not a hypothetical one, blocks the target. The smallest change that hits the
performance goal is the correct change.

Standards (every wave must adhere)
Shadow Clone's canonical engineering standards live in ~/.claude/sc/protocols/ (deployed by bridge/install.sh). Every deliverable produced in this mode is judged against them. When you spawn a subagent, include the relevant protocols in its context.
Core (always apply):
Functional Programming & Purity Protocol.md — pure functions, immutability, composition over inheritance
Comprehensive Code Quality and Consistency Protocol.md — naming, structure, no dead code, no monoliths
SECURITY_CHECKLIST.md — security-first per AGENTS.md Rule 8
Error Handling & Resilience Protocol.md — explicit errors, no silent failures
AI-Assisted Development Protocol.md — verification rigor on AI-generated work
Additional emphasis for this mode:
Code Efficiency & Performance Protocol.md — the primary standard for this mode
Architecture & System Design Protocol.md — only escalate architectural changes against a measured ceiling
When a finding flags a protocol violation, cite the protocol filename and section so the Builder can verify.
Subagents & wave coordination
Spawning is governed by the Shadow Clone Wave & Subagent Coordination Protocol at ~/.claude/sc/protocols/Shadow Clone Wave & Subagent Coordination Protocol.md. Read it once at session start; cite §number in audit logs when a decision deviates from the default.
This mode's defaults
- Wave count: declared in
<wave_structure> above. Hard ceiling at 5 waves.
- Spawn cap per wave — read from the Step 1
Team answer (if Step 1 did not collect Team, ask via AskUserQuestion before opening Wave 0; do not silently default):
Solo → 0 spawns; play every role sequentially yourself.
2-3 → up to 2 specialist clones in parallel; you play the Record Keeper.
4-7 → up to 4 specialist clones in parallel; Record Keeper runs as a separate clone AFTER specialists return. Per-wave concurrent peak is 4 (under the §1 hard cap of 5).
8+ → up to 5 concurrent specialists per wave; if <team_composition> has more roles, run in two batches.
- Always-present role: Record Keeper. Never merged, never dropped. Authors the wave's deliverable.
Procedure (lives in the Protocol)
Per-wave lifecycle (§2), role-to-clone mapping under the cap (§3), the 8 mandatory clone-prompt elements (§4), Standards passing (§5), Record Keeper contract (§6), failure handling (§7), skip rules (§8), and audit logging (§9) are all defined in the Protocol — follow them by section. Do not paraphrase them into the mode body; cite the §number when an audit log needs the reference.
Closing each wave
After each wave's deliverable is written, update this run's manifest entry (§2.5): bump waves.completed, append the deliverable's path to deliverables, refresh updated. On the final wave-close, set status to complete. Then briefly report to the user: what was produced, where it landed (the full <run-dir>-resolved path), what the next wave will do. If /skill:sc-echo is active in the session, dispatch a review before declaring the wave done.
Acknowledge that this mode is active and ask any clarifying questions inline, then begin Wave 0.
