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

overflow-copilot 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 145 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Preamble (run first)

# Suiperpower telemetry. Routes through the CLI so projects.json + Convex stay in sync.
# Silent on failure so the skill never blocks. Opt out: SUIPERPOWER_TELEMETRY=off.
#
# AGENT NOTE: when this skill finishes, run the matching completion command:
#   suiperpower track overflow-copilot idea completed
# Or use "failed" / "aborted" if it ended that way.
command -v suiperpower >/dev/null 2>&1 && suiperpower track overflow-copilot idea started >/dev/null 2>&1 &
true

If TEL_PROMPTED is no, before doing real work, ask the user:

Help suiperpower get better. We track which skills get used and how long they take. No code, no file paths, no PII. Change anytime in ~/.suiperpower/config.json.

A) Sure, anonymous B) No thanks

Write the answer to ~/.suiperpower/config.json telemetryTier field and create ~/.suiperpower/.telemetry-prompted. Then continue.

What this skill does

Searches the Sui Overflow archive (deepsurge.xyz, the official submission and judging platform) for past hackathon projects relevant to a candidate idea. Returns a summary of what has been tried, what won, what failed, and where gaps remain. Helps the user position their candidate against history rather than reinventing it.

Includes structured data from the 2025 Sui Overflow winners (46 projects across 9 tracks), covering technology usage, winning patterns, and 1st place projects per track. See references/overflow-2025-winners.md for the full dataset.

This is the Sui-specific analog of a "past hackathon copilot". It only covers Sui Overflow; for ecosystem-wide research, route to competitive-landscape.

When to use it

  • The user is preparing for Sui Overflow 2026 and wants to learn from past entries.
  • The user has a candidate idea and wants to confirm no past Overflow team has built it (or, if so, what happened next).
  • The user is browsing for inspiration in the past archive.

When NOT to use it

  • The user wants ecosystem-wide competitor research, route to competitive-landscape.
  • The user wants to submit to Sui Overflow, route to submit-to-sui-overflow.
  • The user wants to pick a sponsor track, route to pick-my-sui-track.

Changes

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.
