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.

SkillSpector: 5 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00241 | $0.06602 |
| Opus 5.5 | $0.00096 | $0.02641 |
| Sonnet 5.5 | $0.00048 | $0.01320 |
| Haiku 4.5 | $0.00024 | $0.00660 |
Grade A, and why
shadscan 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 — 347 lines — stays where its author put it; the contents beside it link to each section on GitHub.
shadscan — UI-quality & accessibility pre-deploy gate for React/shadcn apps
Runs on a web project that already exists and uses shadcn. It wraps the third-party shadscan CLI — a deterministic static audit of UI fundamentals — and turns its report into applied fixes, routing each finding to the skill that owns it.
This is the gate that covers what neither sibling can see. compliance-audit reads the legal surface,
vercel-doctor reads the cost surface; nothing in dev-flow mechanically verified that the UI we
prescribe actually got built — that the reduced-motion guard transitions mandates is really there,
that the form errors forms specifies are really rendered, that a route has a loading boundary at all.
Third-party tool. shadscan is not an official shadcn product — it's an independent open-source project by TheOrcDev, published to npm as
@shadscan/cli(binshadscan, MIT). Verified against the npm registry + repo README (at time of writing: 0.9.0, ruleset2026.07.41, reportschemaVersion 9— the report shape is versioned, re-check it). From the README, verbatim: "The default scan is deterministic and read-only. It does not start the app, edit files, call an AI model, upload source, or require application secrets." That makes it safe to run on a private codebase without the--offlinedancevercel-doctorneeds.
Verified invocation + flags
npx --yes @shadscan/[email protected] # explore: human output, same pin
npx --yes @shadscan/[email protected] --json --no-interactive \
> docs/ui/shadscan.json # audit: PINNED — the mode this skill uses
npx --yes @shadscan/[email protected] --fail-under 70 --no-interactive # CI gate: pinned + ratcheted
⚠️ Pin the version for anything you will compare. npx --yes @shadscan/cli resolves to latest on
every call — during a single session it went 0.9.0 → 0.10.0 (ruleset 2026.07.41 → 2026.07.42, 59
rules → 60), silently making a before/after diff a comparison across two different rulesets. shadscan
knows this: the verification.shadscanCommand it emits in its own acceptance criteria is already
pinned (pnpm dlx @shadscan/[email protected] --json). Follow it. Pin the baseline run, pin the re-run, and
only drop the pin when you deliberately want the newer ruleset — then re-baseline instead of diffing.
The explore line is pinned too: --yes runs a third-party package without asking, and an unpinned one
runs whatever was published last.
What ships with it
1 file 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.

shadscan is a skill published in the GitHub repository lukedj78/dev-flow (6 stars, last pushed 5d ago), licensed MIT. It adds 241 tokens to every session and 6,602 once invoked, about $0.0010 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 2026-08-31.
