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 | $0.00041 | $0.00432 |
| Opus 5 | $0.00020 | $0.00216 |
| Sonnet 5 | $0.00008 | $0.00086 |
| Haiku 4.5 | $0.00004 | $0.00043 |
Grade A, and why
better-all-best-practices 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 6d 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.
What it actually says
better-all Best Practices
Model concurrent work as a dependency graph whose task names define the data flow, so independent operations run together while dependent operations remain explicit, inferred, cancellable, and predictable when failures occur.

Effective Strategies for better-all
Read the references that apply to the current task before writing or reviewing better-all code.
- Declare concurrency and data dependencies in the task graph.
- Declare direct data dependencies in the task graph so independent tasks run concurrently instead of being serialized by manual stages.
- Use method syntax for tasks that read sibling results so
this.$is the bound task context rather than lexicalthis.
- Let the graph own cancellation and failure semantics.
- Pass a child operation's task signal through when it accepts an
AbortSignal, so a sibling failure can stop that work without a second cancellation system. - Choose the matching graph operation when the caller needs either fail-fast behavior or every outcome instead of manually staging the dependency graph.
- Pass a child operation's task signal through when it accepts an
- Preserve result information that the task graph already proves.
- Retain inferred task results when task return types already describe the result object so duplicated result interfaces cannot drift.
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

better-all-best-practices is a skill published in the GitHub repository Casper-Studios/casper-marketplace (12 stars, last pushed 6d ago), licensed MPL-2.0. It adds 41 tokens to every session and 432 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 2026-08-30.
