fierce-compete

fierce-compete is a command for Claude Code from seokan-jeong/team-shinchan. It costs 15 tokens per session (357 once invoked), scanned A, original, MIT.

A command that runs several independent implementations of the same coding task, scores them against each other, and applies the selected winner.

In plain words
What is it for?
Use it for contested changes such as rate limiters, CSV parsers, authentication middleware, or other tasks where you want the best of several implementations.
Why use it?
It helps when comparing multiple designs is worth the extra work and a single implementation may not be the best option.

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

fierce-compete 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 12d 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

Fierce Compete Command

A main-loop Workflow runs a competitive tournament: N builder agents independently solve the same task and each returns an apply-ready patch (read-only — no collisions, nothing to merge), an Action-Kamen judge scores them head-to-head, and the winner is selected deterministically by total score and applied. Use when the best of N implementations is worth the cost.

See skills/fierce-compete/SKILL.md for the full procedure.

Usage

/team-shinchan:fierce-compete [the implementation task; optionally "best of N"]

Examples

/team-shinchan:fierce-compete "implement the rate limiter — best of 3"
/team-shinchan:fierce-compete "two approaches to the CSV parser, pick the cleaner one"
/team-shinchan:fierce-compete "refactor auth middleware; compete 3 designs"

When to use this vs /team-shinchan:debate (competitive-code mode)

Use fierce-compete Use debate competitive-code (Midori)
High-value contested implementation; you want a schema-validated, deterministically-scored tournament Quick best-of-N is acceptable
Patch-return (read-only builders, winner applied + tested in the main loop) Worktree-based, Task-orchestrated
Explicit opt-in (runs a Workflow, token-heavy) Auto/keyword-triggered, cheaper

The winner is recorded to .shinchan-docs/debate-decisions.md (shared ledger) and applied with git apply, then verified.

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.
