solid-ssr-hydration-debugger

solid-ssr-hydration-debugger is a skill for Claude Code, Codex from lvcoi/solidJSkills. It costs 46 tokens per session (589 once invoked), scanned A, original, MIT.

A debugging guide for SolidJS applications that render pages on a server and then make them interactive in the browser. It finds cases where the server's HTML differs from what the browser expects.

In plain words
What is it for?
Use it to investigate mismatched server and browser output, async timing issues, conditional rendering changes, and unsafe browser API access. It also provides fix guidance and a checklist for verifying both sides match.
Why use it?
It helps explain hydration errors and browser-only code that accidentally runs on the server. It turns hard-to-repeat rendering problems into a fixed reproduction and a clear cause.

Token cost

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.

Security

Grade A, and why

solid-ssr-hydration-debugger 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 2mo 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.

Trigger

Use when SSR output and client hydration diverge, or browser-only assumptions leak into server render paths.

Required Inputs

  • Reproduction steps and environment mode.
  • Affected route/component boundaries.
  • Error logs and observed mismatch behavior.

Workflow

  1. Build deterministic reproduction path with explicit route/component inputs.
  2. Isolate mismatch class: non-deterministic render, browser-only access, async timing, or conditional render drift.
  3. Recommend fix strategy using SSR-safe primitives and hydration boundaries.
  4. Provide verification checklist for server/client parity.

Failure Modes

  • Non-reproducible issue report: request exact steps and route context.
  • Fix without root-cause classification: mark invalid output.
  • Browser API in server path unresolved: fail until guarded.

Output Contract

Return DomainGuidanceOutput with root-cause decisions, remediation handoff, and citations referencing normalized doc_id values.

Validation

  • node tools/scripts/validate-skills.mjs --skill solid-ssr-hydration-debugger
  • node tools/scripts/validate-solid-corpus.mjs

Key Corpus References

Use these doc_id values with the read_corpus_doc MCP tool:

  • solid-core.reference.rendering.hydrate — client hydration attachment
  • solid-core.reference.rendering.is-server — SSR guard constant
  • solid-core.reference.rendering.render-to-stream — streaming SSR with Suspense
  • solid-core.reference.rendering.hydration-script — hydration bootstrapper
  • solid-router.solid-router.rendering-modes.ssr — router SSR rendering mode

References

  • ../../references/solidjs/performance-ssr.md
  • ../../references/solidjs-normalized/docs/reference/rendering/hydrate.md
  • ../../references/solidjs-normalized/docs/reference/rendering/is-server.md

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.
