SkillSignal prompt templates
Provide the task, context, and acceptance criteria
These prompts were written by SkillSignal from the source structure; they are not upstream text.
Task-start prompt
Confirm source fit, inputs, and outputs before acting.
Use parallel-execution-optimizer to help me with: [specific task]. Context: [files, data, or background]. Constraints: [environment, scope, and prohibited actions]. Before acting, check the pinned SKILL.md and explain which sections apply, what inputs are still missing, and what you will deliver.
Source-guided execution
Make the Agent explicitly follow the key extracted sections.
Apply the pinned parallel-execution-optimizer source to [task]. Pay particular attention to these source sections: “Core Pattern”, “Lane Matrix”, “Execution Rules”, “Output Shape”, “Failure Modes”. Preserve the important decision at each step. Mark facts not covered by the source as “needs confirmation” instead of inventing them. Then verify the result against my acceptance criteria: [criteria].
Result-review prompt
Check omissions, permissions, and source drift before delivery.
Review the current parallel-execution-optimizer result: (1) does it satisfy the original task; (2) were any applicable steps or limits in the pinned SKILL.md missed; (3) did it perform any unauthorized file, command, network, or data action; and (4) which conclusions remain unverified? List issues first, then fix only what the source or user authorization supports.

Parallel Execution Optimizer
Use this skill when speed comes from doing independent work at the same time: repo inspection, file reads, API checks, browser checks, build/test lanes, deploy readbacks, or multi-worktree implementation passes.
Core Pattern
Turn urgency into a dependency graph before acting.
- Define the objective and done signal.
- Split work into lanes.
- Mark each lane as parallel, sequential, or gated.
- Run independent reads/checks together.
- Keep writes isolated by file, worktree, branch, service, or dataset.
- Merge only after evidence shows the lanes are compatible.
- End with a verification table, not a vague speed claim.
Lane Matrix
Before a large push, write a compact matrix:
Lane | Can run in parallel? | Write surface | Risk | Verification
Repo scan | yes | none | low | rg/git status outputs
Backend patch | maybe | src/api | medium | unit tests
Frontend patch | maybe | app/components | medium | browser screenshot
Deploy readback | after build | remote service | high | live URL + logs
Only run lanes in parallel when their write surfaces do not collide.
Execution Rules
- Batch file reads, searches, status checks, and metadata queries.
- Use isolated worktrees for large unrelated implementation lanes.
- Start long-running tests, builds, backfills, and deploys in separate sessions, then poll them deliberately.
- If a lane discovers a blocker that changes the plan, pause dependent lanes and update the matrix.
- Never let a background process outlive the turn unless the user explicitly asked for a continuing service.
- Do not parallelize destructive commands, migrations, writes to the same table, or live customer-impacting deploys without an explicit gate.
Output Shape
Use this when reporting:
Parallel execution result:
- Lanes run: 5
- Lanes completed: 4
- Blocked lane: deploy readback, waiting on DNS propagation
- Fast path found: batched repo scan + focused tests
- Verification: lint pass, unit pass, live smoke pass
Failure Modes
- More concurrency that creates conflicting edits.
- Benchmarking the tool instead of the task.
- Treating "fast" as done before correctness is proven.
- Forgetting to poll running sessions.
- Hiding skipped checks behind a success summary.
