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 | $0.00078 | $0.01702 |
| Opus 5 | $0.00039 | $0.00851 |
| Sonnet 5 | $0.00016 | $0.00340 |
| Haiku 4.5 | $0.00008 | $0.00170 |
Grade A, and why
reading-list-prioritizer 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 12d 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 — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Reading List Prioritizer
This skill takes your personal reading list (a local markdown file with article titles and/or URLs) and returns a structured weekly reading plan: items scored by relevance to your role, grouped by topic, with a "Read this week" shortlist at the top.
Input:
- A markdown file (.md) with your reading list — one item per line, as
[Title](URL)links, bare URLs, or plain text titles - Your role or current focus area (stated in 1–2 sentences in your message)
Output:
- Markdown response with a prioritized "Read this week" shortlist + full list grouped by topic, each item labeled [High] / [Med] / [Low]
Language Detection
Detect the user's language from their message:
- If Russian (or contains Cyrillic): respond in Russian
- If English (or other Latin-script language): respond in English
- If ambiguous: respond in the language of the trigger phrase used
Instructions
Step 1: Validate Input
-
Check that a reading list file has been provided (uploaded or pasted)
- If no file and no pasted list: stop and return: "Please provide your reading list as a .md file or paste the list directly."
- Accepted formats:
.mdfile, pasted markdown list, plain text list
-
Check that the user's role or focus area is stated in their message
- If missing: ask for it before proceeding — "What's your current role or focus area? (e.g., 'PM focused on AI product strategy')"
- Do not guess or assume a generic role — prioritization depends on it
-
Validate file content: must contain at least 3 parseable items
- If fewer than 3 items: proceed but note "Short list — showing all items with priority labels"
- If file is empty or contains no recognizable items: stop with message "The reading list appears empty. Please check the file format."
Step 2: Parse the Reading List
- Read each line of the list and extract:
- Title: from
[Title](URL)format, or plain text line, or domain-derived label if only a bare URL - URL/domain: extract domain from URL if present (e.g.,
nngroup.com,hbr.org,stratechery.com) - Tags or notes: if the user appended a tag or comment after the link (e.g.,
[Article](url) #ux), extract them
- Title: from
What ships with it
4 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.

reading-list-prioritizer is a skill published in the GitHub repository KirKruglov/claude-skills-kit (18 stars, last pushed 1mo ago), licensed MIT. It adds 78 tokens to every session and 1,702 once invoked, about $0.0004 per session on Opus 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 2026-08-30.
