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 | $0.00093 | $0.03162 |
| Opus 5 | $0.00046 | $0.01581 |
| Sonnet 5 | $0.00019 | $0.00632 |
| Haiku 4.5 | $0.00009 | $0.00316 |
Grade A, and why
wjttc-builder 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.

The opening of the file, as written. The whole thing — 344 lines — stays where its author put it; the contents beside it link to each section on GitHub.
WJTTC Builder - Championship Test Suite Generator
Philosophy: "We break things so others never have to know they were broken."
This skill generates F1-inspired test suites following the WJTTC (Wolfe James Tests The Code) methodology.
GOALS
| Goal | How |
|---|---|
| Pre-defined | Test plan before code → improves code quality |
| Inline Testing | Tests/approves at write time → catches bugs at inception |
| Layer 1 → Layer 2 | Industry + Expert = GOLD Code |
| AI Optimized | 100% bi-sync with project.faf |
| Best Code Possible | ✪ Championship standard |
GOLD Code ✨

Position in Development Pipeline
WJTTC comes AFTER project.faf, BEFORE coding:
1. project.faf → Define WHAT we're building (context)
2. WJTTC-TESTS.md → Define SUCCESS CRITERIA (tests first)
3. Code → Build to pass the tests
4. Test → Pass/Fail
5. Repeat → Until Championship grade
Test-Driven Code (TDC)
The WJTTC Cycle:
Think → Cross-check → Confirm → Code → Test → [Repeat]
│ │ │ │ │
│ │ │ │ └── Pass/Fail verdict
│ │ │ └── Write implementation
│ │ └── Green light to proceed
│ └── STOP if missing info - get it first
└── Understand what we're building
Cross-check Gate: STOP if missing information. Get it before proceeding.
- Missing requirements? Ask.
- Unclear acceptance criteria? Clarify.
- Unknown edge cases? Define them.
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.
- 9d ago First seen · 344 lines · 93 tokens per session scan A f8879c240b36
wjttc-builder is a skill published in the GitHub repository Wolfe-Jam/faf-skills (4 stars, last pushed 21d ago), licensed MIT. It adds 93 tokens to every session and 3,162 once invoked, about $0.0005 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.
