Claude Code Skills Marketplace is a collection and marketplace of skills, plugins, agents, and instructions that extend Claude Code with specialized development workflows. It is for developers who want to install existing workflows or create, validate, and package their own Claude Code skills.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00090 | $0.10579 |
| Opus 5.5 | $0.00036 | $0.04232 |
| Sonnet 5.5 | $0.00018 | $0.02116 |
| Haiku 4.5 | $0.00009 | $0.01058 |
Grade A, and why
report-with-html 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 6d 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 — 677 lines — stays where its author put it; the contents beside it link to each section on GitHub.
report-with-html
Create a reader-facing HTML artifact whose information architecture follows the reader's question—not the author's implementation checklist.
Trigger boundary
Use this skill when the requested artifact is itself a visual HTML report or interactive information tool. Typical outputs include:
- a system, architecture, journey, causal, decision, comparison, or gap view;
- a client-facing data report or one-pager;
- a data/archive browser or review workbench;
- an explicitly requested HTML/web presentation.
Do not trigger it for a normal status reply, generic review, code diff, issue list, or Markdown document. Those tasks may be reported in chat unless the user explicitly asks to turn the result into a visual HTML artifact.
The default delivery is the verified HTML opened in a browser. A PNG is a QA artifact
and is delivered only when the user asks for an image. If the user needs editable
PowerPoint, finish and verify the HTML first, then use deck-creator (Route C).
SSOT map
Visualization judgment lives in another skill — load it before designing any chart or
geometry. data-visualization-discipline:data-visualization-discipline owns which form
fits the content, which chart type and summary statistic to use, whether segments may be
aggregated, how many categorical colors are allowed, cross-view color identity, table
discipline, the antipattern list, and the pre-delivery self-check gate. This skill does not
restate those rules; a second copy would drift. This skill owns the report page itself:
register calibration, the component shelf, the approved corpus, page order, the decision-card
contract, interaction contracts, and browser verification.
- Reader-facing principles, content boundary, decision-card contract, accessibility:
references/design-principles.md - Layout density (铺满画布 / 消灭空洞), page order as narrative rhythm, the HTML table
micro-spec, and form → component implementation:
references/visualization-patterns.md. Not conditional on having already chosen a form — most of it applies to every page regardless of what you draw. This line used to open with "Chosen form →", which reads as a precondition; a 2026-08 delivery filed the file under "the implementation lookup I'll consult if I build one of those components", never opened it, and shipped a page missing three of its rules. The gate a step hides behind must not be a step you have not taken yet. - Approved corpus and register calibration:
references/approved-examples.md - Reusable interactions and their keyboard contracts:
references/interaction-components.md - Numbered hover/focus source previews and original-content adapters:
references/citation-source-preview.md(candidate/pilot; load when citations use previews). - Photos, screenshots and explanatory diagrams:
references/visual-evidence.md. Load before authoring when objects, physical choices, visual defects or relationships need to be seen; do not wait until images have already been selected. - Long-lived/generated-page maintenance:
references/long-lived-report-maintenance.md - Fresh-context review payload:
references/independent-review-prompt.md - Warm-paper starter implementation:
assets/report-template.html

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.

report-with-html is a skill published in the GitHub repository daymade/claude-code-skills (1,473 stars, last pushed today), licensed MIT. It adds 90 tokens to every session and 10,579 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 2026-09-25.
