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 | $0.00076 | $0.01414 |
| Opus 5 | $0.00038 | $0.00707 |
| Sonnet 5 | $0.00015 | $0.00283 |
| Haiku 4.5 | $0.00008 | $0.00141 |
Grade A, and why
sprint-review-summarizer 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 — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sprint Review Summarizer
This skill transforms plain-language sprint summary notes into a structured stakeholder document covering delivered items, deferred work, risks, and next sprint focus. It works from any free-form text or markdown file — no integrations, no YAML, no Jira required.
Input:
- Sprint notes as pasted text or markdown file (any format accepted)
- Optional: sprint number, team name, sprint goal (for metadata enrichment)
Output:
- Markdown stakeholder document with sections: Executive Summary, Delivered, Deferred, Risks & Issues, Next Sprint Focus, Key Decisions (if detected)
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 and Parse Input
-
Check that sprint notes content is provided (pasted text or file reference)
- If input is empty or whitespace only: Stop. Return: "No sprint notes provided. Paste your sprint summary or provide a file path."
-
Check input format
- If input resembles a structured Jira/CSV export (column headers, ID fields, etc.): Inform the user — "This looks like a structured export, not plain-language notes. This skill works best with free-form sprint notes." Offer to attempt processing if user confirms.
- Otherwise: proceed with parsing
-
Extract optional sprint metadata if present in notes:
- Sprint name or number (e.g., "Sprint 24", "Q2 Sprint 3")
- Dates (e.g., "May 5–19")
- Team name
- Sprint goal
- If metadata is missing: use placeholder "Sprint [YYYY-MM-DD]" for the heading and continue without blocking
Step 2: Classify Items into Four Categories
-
Read all content and identify discrete items (sentences, bullet points, paragraphs describing work)
-
Map each item to one of four categories using semantic heuristics:
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.

sprint-review-summarizer is a skill published in the GitHub repository KirKruglov/claude-skills-kit (18 stars, last pushed 1mo ago), licensed MIT. It adds 76 tokens to every session and 1,414 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.
