Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00039 | $0.00884 |
| Opus 5 | $0.00019 | $0.00442 |
| Sonnet 5 | $0.00008 | $0.00177 |
| Haiku 4.5 | $0.00004 | $0.00088 |
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
- Restate the target, the success condition, and any no-touch boundaries before taking action.
- 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.
- Smallest effective change: Choose the minimal optimization that attacks the highest-friction segment. Prefer caching, batching, parallelism, or path simplification over rewrites.
- 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.
- Package the result as the deliverables below, with confidence, assumptions, and unresolved risk called out explicitly.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

longstrider is a skill published in the GitHub repository Hmbown/Wizards-of-the-Ghosts (107 stars, last pushed 5mo ago), licensed CC0-1.0. It adds 39 tokens to every session and 884 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
Other skills, from other repositories
linter-agent
Use when detecting and fixing code style violations, enforcing project conventions, ensuring consistent formatting.
perf-agent
Use when measure before optimizing, target actual bottlenecks proven by profiling, verify with benchmarks.
manage-skills
A maintenance workflow for checking whether project verification skills still cover the code and rules that changed during a session.
systematic-debugging
Structured debugging methodology — use before proposing fixes for any error or failure. Covers: code bugs, build errors, deploy failures, config conflicts, dependency issues, infra problems. Also use when previous fix attempts failed or root cause is unclear.
review-loop
Run the adversarial verification loop — implement, then hand the change to a fresh checker that did not write it, fix what it finds, and re-dispatch until APPROVE. Use before claiming any behavioural change is done, and on requests like "review loop", "adversarial review", "independent review", "get this verified"…
reproduce
Reproduce a cloudflare/agents GitHub issue by scaffolding a minimal Agents/Worker project and deploying it to a temporary Cloudflare account, then report findings back on the issue.
