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 | $0.00100 | $0.00674 |
| Opus 5.5 | $0.00040 | $0.00270 |
| Sonnet 5.5 | $0.00020 | $0.00135 |
| Haiku 4.5 | $0.00010 | $0.00067 |
Grade A, and why
verification 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 18d 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
Verification
A cross-DCC, read-only verification toolset (affinity: any) that closes the
capture-and-look quality loop with deterministic, machine-checkable signals.
Inspired by img2threejs's "deterministic-first, model-last" review design, it
computes evidence in-band — statistics, hashes, and verdicts — and never ships
pixels to a model unless a caller explicitly asks for image/both payloads.
The four tools map to the four legs of the deterministic capture contract:
capture_review_views— the fixed front / side / top / three-quarter view plan, viewport-only, fails loudly on a missing, wrong-size, or blank frame.image_stats— mean luma, stddev, histogram, uniformity, and bad-frame flags (white playblast, near-black render, missing display transform).validate_scene_vs_spec— hierarchy names, material bindings, per-mesh UV coverage, part existence, non-manifold, and Euler checks, before export.make_comparison_sheet— reference + renders side-by-side into one image; packages evidence and computes no scores.
Pixel-level metrics (pHash / dHash / aHash, silhouette IoU, SSIM, CIEDE2000,
Sobel edge maps) live in dcc_mcp_core.verification as deterministic library
functions, not skill tools, so callers gate on them directly.
Safety Contract
Every tool is read-only and side-effect free except make_comparison_sheet,
which writes exactly one output image at the requested path. Tools never mutate
the input captures and never launch a DCC. PPM/PGM inputs decode through the
standard library; other formats (PNG/JPEG/EXR) decode through ffmpeg on
PATH (or vx ffmpeg) and fail loudly when the decoder is unavailable.
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

verification is a skill published in the GitHub repository dcc-mcp/dcc-mcp-core (68 stars, last pushed today), licensed MIT. It adds 100 tokens to every session and 674 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-09-19.
