Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00014 | $0.00502 |
| Opus 5 | $0.00007 | $0.00251 |
| Sonnet 5 | $0.00003 | $0.00100 |
| Haiku 4.5 | $0.00001 | $0.00050 |
Grade A, and why
leaderboard scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
/leaderboard — ELO Ratings
Show the persistent ELO ratings leaderboard. Ratings are updated after each /forge run based on who wins and loses.
How to invoke
/leaderboard # show all task classes
/leaderboard algorithm # show only algorithm class
/leaderboard bugfix # show only bugfix class
Step-by-step workflow
- Parse optional task class from the user's message.
- Run the leaderboard formatter:
# All classes
bash "${CLAUDE_PLUGIN_ROOT}/scripts/elo-show.sh"
# Specific class
bash "${CLAUDE_PLUGIN_ROOT}/scripts/elo-show.sh" --task-class "algorithm"
- Present the output to the user. If no data exists yet, explain that ratings start building after the first
/forgerun.
Task classes
Ratings are tracked per task class (auto-detected from the forge task description):
| Class | Keywords |
|---|---|
algorithm |
algorithm, sort, search, scoring, math, compute |
refactor |
refactor, rename, extract, simplify, reorganize |
bugfix |
fix, bug, error, crash, broken, regression |
feature |
add, implement, create, build, feature, new |
test |
test, spec, coverage, assert |
docs |
doc, readme, comment, changelog |
other |
(default) |
How ELO works
- All buddies start at 1200
- K-factor: 32 (configurable)
- Winner gains points, loser loses points (zero-sum)
- Ratings below 100 are floored
- Provisional status for < 10 games
Configuration
| Key | Default | Description |
|---|---|---|
elo_enabled |
true |
Enable/disable ELO tracking |
elo_k_factor |
32 |
ELO K-factor (higher = more volatile) |
Rules
- Read-only. This skill only displays ratings, never modifies them.
- Suggest /forge if no data exists yet.
- Keep it brief. Just show the table, no analysis unless asked.
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.

leaderboard is a skill published in the GitHub repository cukas/claudes-ai-buddies (9 stars, last pushed 4mo ago), licensed MIT. It adds 14 tokens to every session and 502 once invoked, about $0.0001 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 2026-08-31.
