Cost Booster Edit

This is the execution half of the cost-booster pair. Route classifies whether a transform is simple enough for deterministic WASM handling, then this skill actually runs it via agent-booster's apply() function. The benchmark numbers are legitimate: 12/12 correctness on structural transforms like var-to-const or add-error-handling, sub-millisecond median latency, and genuinely zero cost since there's no LLM call. The 1838x speedup claim versus Sonnet is real but only meaningful for bulk edits where you'd otherwise burn tokens on repetitive transforms. Use it when you have many files needing the same mechanical change. Skip it if the edit requires any reasoning about intent or naming.

Cost Booster Edit

Direct wrapper around agent-booster.apply() (npm agent-booster v0.2.x, exposed via agentic-flow/agent-booster). Use when a transform is already classified as Tier 1 eligible — cost-booster-route recommends whether; this skill executes.

When to use

Bulk transforms across many files (var → const, add-types, remove-console, add-error-handling, async-await, add-logging).
Any simple, structural edit where an LLM would otherwise be called and billed.
Inside CI pipelines where determinism + zero-cost matter more than naturalness.

Do NOT use when the transform requires reasoning about intent, naming, or cross-file context — those are Tier 2/3 jobs.

Steps

Take inputs — intent (one of the 6 booster intents) and file path.
Read the source to a variable, derive the intended edit text from the intent (caller supplies).
Invoke — run from anywhere under v3/ so agent-booster resolves:
