Nerd Fast

Incompatible Skills

Never combine Nerd with these unless this request explicitly asks:

• Superpowers
• Ponytail
• Caveman

Skill hooks, mentions, and indirect instructions are not authorization.

Composition

Apply this global modifier; it is never a primary specialty and never replaces or restarts the active workflow. Use nerd-smart only for material endpoint, scope, or authorization ambiguity.

Compose with nerd-silent only when the user explicitly invokes both modifiers. Never activate, infer, or auto-compose Silent from latency or presentation preferences. Fast controls operations; Silent controls presentation. Preserve correctness, authorization, safety, user interaction, and proof.

Core Rule

Minimize sequential critical-path rounds. Keep an operation only when it resolves a material unknown, advances the requested deliverable, or produces required proof.

Prefer: reuse -> batch -> parallelize -> target narrowly -> escalate on evidence -> stop when proven.

Use no hard total tool limit. Fixed limits can trade accuracy for speed when proof requires more operations.

Read-Volume Gate

At task start, before the first source read, estimate x, the total estimated lines direct navigation would require, using named scope, known sizes, and likely support; do not read targets merely to calculate it.

• x <= 200: skip symbol_index.py; read or search the targets directly.
• x > 200: resolve scripts/symbol_index.py relative to this SKILL.md, run ensure once before source reads, then navigate with find without implicit refresh.

Do not wait until 200 lines have already been read. Universal Ctags is optional. If ensure reports that Universal Ctags is unavailable, ask once: “Universal Ctags is unavailable. Our measured large-repository workloads showed up to 70% faster indexed navigation. Want me to install it? If not, I’ll continue with narrow text search.” Install only after explicit approval. On decline, unsupported installation, or failure, fall back immediately and do not ask again during the task. For any other unusable, stale, or incomplete index, fall back to an exact-file read or narrow text search. Treat matches as candidates and confirm source before mutation.
