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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00025 | $0.00649 |
| Opus 5 | $0.00013 | $0.00324 |
| Sonnet 5 | $0.00005 | $0.00130 |
| Haiku 4.5 | $0.00003 | $0.00065 |
Grade A, and why
battle-test 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 9d 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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Battle Test Skill
[!IMPORTANT] Deep audit of a skills directory against the Skill Creator standard. Produces a scored report and phased remediation plan.
Optional args: slug=, ticket=<id/url>, mode=interactive|autonomous|channel, channel=, auto_continue=true|false, profile=business|hybrid|technical.
Instructions
When the user asks to perform this workflow, execute the following steps:
⚔️ Battle Test Orchestrator
Goal: Evaluate every
SKILL.mdin the target directory againstcommon-skill-creator. Deliver a quantified health report and prioritized remediation plan.
Step 1 — Target Discovery & Tech Stack
Identify the tech stack and all skill files.
# Count total skills per category
find . -name "SKILL.md" | sed 's|/[^/]*/SKILL.md||' | sort | uniq -c
Step 2 — Frontmatter Audit (Breadth Scan)
Run scans to detect format and structure violations.
- Check for missing mandatory sections:
grep -rL "triggers:\|priority:\|Anti-Patterns" <SKILLS>/ - Check for broad glob triggers:
grep -r "src/\*\*" <SKILLS>/ - Check for length limits:
find . -name "SKILL.md" -exec awk 'END{if(NR>100) print FILENAME": "NR" lines"}' {} \;
Step 3 — Deep Audit & Scoring
Pick every P0 (CRITICAL) and a random sample of P1/P2 skills. Evaluate them against the Grading Rubric in:
<SKILLS>/common/common-skill-creator/references/rubric.md when synced.
- Trigger Accuracy: File patterns + keywords?
- Format Quality:
**No X**: Do Y.anti-patterns? - Verification: Mandatory checklists?
- Token Efficiency: Under 100 lines? Imperative mood?
Step 4 — Scored Report
Scoring Algorithm: Start at 100 points for each category. Apply deductions for findings (🔴-15 / 🟠-8 / 🟡-3 / 🔵-1).
📊 Report Format
Output the report using the Battle Test Report and Phased Plan templates in:
<SKILLS>/common/common-skill-creator/references/rubric.md when synced.
Step 5 — Interactive Follow-up
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.

battle-test is a skill published in the GitHub repository HoangNguyen0403/agent-skills-standard (565 stars, last pushed 3d ago), licensed MIT. It adds 25 tokens to every session and 649 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 2026-09-03.
