What it does

Asupersync Mega Skill is an agent skill from Dicklesworthstone/asupersync. Build, migrate, debug, and maintain Asupersync. Use when working with Tokio migration, Cx/Scope/cancellation, local tasks, Lab replay, browser/Wasm, protocols, databases, OTLP, or repository proof.

Its SKILL.md is about 2.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 40 other files, including scripts and reference files (for example `SELF-TEST.md`, `references/ADOPTION-LANES.md` and `references/ADVANCED-FEATURES.md`).

It sits in DevOps & Cloud. It works with OpenTelemetry, WebAssembly and Rust. The repository describes itself as: Async runtime for Rust where correctness is structural: region-owned tasks, cancel-correct protocols, capability-gated effects, and deterministic replay testing.

When your agent uses it

  • Working with Tokio migration
  • Cx/Scope/cancellation
  • Repository proof

Example prompts

  • “/asupersync-mega-skill”

Requirements

  • Python 3

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. Inventory direct and transitive Tokio-ecosystem dependencies.
  2. Classify each as native replacement, explicit compat holdout, or deliberate
  3. Use the repository's migration readiness planner when available; do not
  4. Replace bootstrap, thread &Cx through owned APIs, then replace detached
  5. Migrate time, sync, I/O, channel, web, database, and protocol slices one at
  6. Add deterministic and native cancellation tests during the migration.
  7. Compile actual external-consumer feature profiles; cfg(test) access and
  8. Remove each compat boundary when its last justified dependency is gone.

What it can do on your machine

Read from SKILL.md and the folder at commit 4394cb8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/, which the agent can run.

    Shell commands in SKILL.md call:

    • python3
    • cargo

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Asupersync Mega Skill loads about 2.9k tokens when it runs, and up to ~86k if it reads all its reference files. Until then it costs about 55 tokens; SKILL.md has 1,148 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~2.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~86k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,148 words (~2,932 tokens).

“Asupersync is a spec-first runtime for structured concurrency, cancel-correct effects, obligations, deterministic testing, and capability security—not a Tokio wrapper. Verify against live evidence.”
