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 | $0.00049 | $0.03204 |
| Opus 5 | $0.00024 | $0.01602 |
| Sonnet 5 | $0.00010 | $0.00641 |
| Haiku 4.5 | $0.00005 | $0.00320 |
Grade A, and why
build-verification-expert 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 8d 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 source is not reproduced here
A licence we could not identify
The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.
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.

build-verification-expert is a skill published in the GitHub repository curiositech/windags-skills (10 stars, last pushed 1mo ago), with no licence file. It adds 49 tokens to every session and 3,204 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 2026-09-03.

verification-loop
6-stage automated verification pipeline producing READY/NOT READY verdict.
init-workspace-verification
Verify init completeness.
doc-claim-validator
Validate that claims in documentation match codebase reality. Extracts verifiable assertions (file paths, commands, function references, behavioral claims, dependencies) from markdown docs and checks them against the actual project. Use after code changes, before releases, or when docs feel untrustworthy.
repository-manager-build-coordination
Content-addressed build/cache coordination for ANY repository via the repository-manager MCP server — dedup-or-build requests, cache-key status, published artifacts, why a key missed cache, and bounded cache reclamation. Routes agents away from a bare, uncoordinated cargo build/uv sync/pnpm build that duplicates work…
phase-enforcement
Evidence-based phase completion enforcement for /dev:feature. Use when orchestrating 8-phase feature development to ensure artifacts exist before phase completion, validation criteria are addressed, outer loops are enforced, and show-your-work requirements are met.
Architecture Validation Plan Guard
Detect missing validation plans (how to verify the design is correct) in design documents and ADRs.
