longstrider

longstrider is a skill for Claude Code, Codex from Hmbown/Wizards-of-the-Ghosts. It costs 39 tokens per session (884 once invoked), scanned A, original, CC0-1.0.

A guide for making an already working system faster without changing what it does.

In plain words
What is it for?
It is for profiling, caching, batching, parallel processing, and comparing performance before and after a change.
Why use it?
It helps locate bottlenecks—the parts that consume the most time—before making targeted improvements.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

longstrider scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Longstrider

Make the path shorter without changing the destination.

What This Skill Does

Longstrider is the optimization spell for systems that already work. It makes the path shorter without changing the destination. It cares about sustained pace, not flashy one-off benchmarks. In this grimoire, Longstrider is treated as a metaphorical spell with a shipping-now delivery profile. Canonical reference input: Longstrider (spell).

When To Use

  • Trigger Longstrider when the user describes a working system that is slower than it should be and asks for speed improvements. Look for:
  • Time complaints with metrics: "takes 22 minutes", "4.2 seconds to load", "p95 is 800ms", "cold start is 8 seconds"
  • Optimization keywords: "bottleneck", "speed up", "optimize", "faster", "profiling", "cache", "parallelize", "batch"
  • Constraint phrases: "without rewriting", "without skipping tests", "without schema changes", "quick wins", "don't want to change the product"
  • Evidence of friction: "most of that is...", "the largest contentful paint is...", "single-threaded Python reading line by line"
  • Measurement mindset: "before/after", "measurement plan", "profile", "identify what's happening"

Prerequisites

  • No extra runtime dependencies beyond Hermes Agent and the normal toolset for this session.

Procedure

  1. Restate the target, the success condition, and any no-touch boundaries before taking action.
  2. Profile first: Identify where time, waiting, or repeated work is actually being spent. Never optimize based on vibes—demand or propose measurement of the real bottleneck.
  3. Smallest effective change: Choose the minimal optimization that attacks the highest-friction segment. Prefer caching, batching, parallelism, or path simplification over rewrites.
  4. Return the speed plan: Deliver a prioritized optimization plan with expected gains, a before-and-after measurement strategy, and a watchlist for correctness, cost, or cache-invalidation regressions.
  5. Package the result as the deliverables below, with confidence, assumptions, and unresolved risk called out explicitly.
