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 | $0.00047 | $0.02023 |
| Opus 5.5 | $0.00019 | $0.00809 |
| Sonnet 5.5 | $0.00009 | $0.00405 |
| Haiku 4.5 | $0.00005 | $0.00202 |
Grade A, and why
remix-v2-routing-review 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 1mo 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 — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Remix v2 Routing Code Review
Loaded by review-remix-v2 (umbrella) to flag routing anti-patterns in app/routes/ modules. See remix-v2-routing for canonical patterns.
Quick Reference
| Issue Type | Reference |
|---|---|
Filename smells (index.tsx, __auth, wrong escape, non-route files) |
references/route-files.md |
Missing <Outlet />, orphan dotted segments, duplicated layout logic |

Default export on a resource, <Link> without reloadDocument, splat params |
references/resource-routes.md |
react-router-dom imports, __double folders, v1-adapter fallback |

Missing <Meta />/<Links />/<Scripts />/<ScrollRestoration />, Vite-vs-Classic <LiveReload />, root ErrorBoundary without document shell |

Scope
This skill flags issues in:
- Files under
app/routes/(filenames, exports, imports, JSX shape) app/root.tsx(document shell, root<Outlet />)remix.config.js(entries that change route discovery:routes(),ignoredRouteFiles,@remix-run/v1-route-convention)- Any module that links to a resource route (
<Link>usage)
Out of scope: loader/action data contracts (covered by remix-v2-data-flow-review), form behavior (remix-v2-forms-review), meta/headers (remix-v2-meta-sessions-review).
Review Checklist
- Index routes named
_index.tsx, notindex.tsx - Pathless layouts use single underscore (
_auth.tsx), not double (__auth/) - Dotted child routes (
users.profile.tsx) have a parent module or use trailing underscore (users_.profile.tsx) - Parent route modules render
<Outlet /> - Splat segments read
params["*"], neverparams.splat/params.rest - Literal dots/special chars escaped with brackets (
sitemap[.]xml.tsx) - Resource routes have no
defaultexport -
<Link>to a resource route usesreloadDocument(or is a plain<a>) - Imports come from
@remix-run/react, notreact-router-dom - Non-route files (CSS, helpers, tests) live in a folder with
route.tsx, or are listed inignoredRouteFiles - Trailing-underscore opt-outs only used when a parent layout actually exists to escape
- Optional segments

What ships with it
5 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.

remix-v2-routing-review is a skill published in the GitHub repository existential-birds/beagle (82 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 47 tokens to every session and 2,023 once invoked, about $0.0002 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 2026-09-16.
