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 | $0.00038 | $0.00268 |
| Opus 5 | $0.00019 | $0.00134 |
| Sonnet 5 | $0.00008 | $0.00054 |
| Haiku 4.5 | $0.00004 | $0.00027 |
Grade A, and why
gauntlex:learn scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
/gauntlex:learn
Ingests a run's results into the Knowledge Forge (ChromaDB) and updates the Adaptive Brain.
Usage
/gauntlex:learn --run-id <run_id> --outcome pass|fail
Execution
gauntlex learn --run-id "$RUN_ID" --outcome "$OUTCOME"
What It Does
- Reads
.gauntlex/reports/<run_id>.json - Writes each attack into ChromaDB with CWE tag + codebase fingerprint
- Updates rolling 30-run EMA effectiveness scores per (CWE, fingerprint-cluster)
- Schedules Breaker prompt rewrite via meta_agent if any CWE < 0.3 effectiveness over 30 runs
- Prints updated effectiveness summary
Output to User
- Number of attacks ingested
- Any CWE categories now flagged for prompt rewrite
- Updated top-5 effective attack categories for this codebase type
- "Forge entries: total" — shows the brain is growing
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.

gauntlex:learn is a skill published in the GitHub repository sanjoy1234/gauntlex (1 stars, last pushed 1mo ago), licensed MIT. It adds 38 tokens to every session and 268 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 2026-08-31.
