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 | $0.00077 | $0.01614 |
| Opus 5 | $0.00039 | $0.00807 |
| Sonnet 5 | $0.00015 | $0.00323 |
| Haiku 4.5 | $0.00008 | $0.00161 |
Grade A, and why
weekly-digest-synthesizer 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 9d 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 — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Weekly Digest Synthesizer
This skill compiles status updates from multiple local .md and .txt files into a structured weekly digest. It groups content by project area, surfaces action items and blockers, and outputs a ready-to-share markdown file named weekly-digest-YYYY-MM-DD.md.
Input:
- Folder path or list of
.md/.txtfiles containing status updates - Optional: digest date (defaults to today), output format preference (concise / detailed)
Output:
weekly-digest-YYYY-MM-DD.md— structured digest with Summary, Projects, Action Items table, Risks & Blockers
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
-
Determine input source from the user's message:
- Folder path → scan all
.mdand.txtfiles in that folder - List of files → use those files directly
- No path provided → scan the current working directory for
.mdand.txtfiles
- Folder path → scan all
-
Verify files exist and are readable:
- If no files found: stop. Report "No .md or .txt files found at [path]. Provide a folder path or list of files to process."
- If a specific file path does not exist: stop. Report "File not found: [path]. Check the path and try again."
-
Check for unsupported file formats:
- If user provides only
.docx,.xlsx,.pdf, or similar: stop. Report "Unsupported file types. This skill processes .md and .txt files only."
- If user provides only
-
Determine digest date:
- If user specifies a date → use that date in output filename
- If not specified → use today's date (YYYY-MM-DD format)
Step 2: Read and Parse Files
- Read each file in turn and extract:
- Project or area name: inferred from filename, H1/H2 heading, or leading section header
- Status indicator: on track / at risk / blocked — detected from keywords ("blocked", "delayed", "at risk", "completed", "done", "✅", "⚠️", "🔴") or inferred from context
- Key updates: bullet points, sentences describing progress, decisions, or changes
- Action items: tasks with any mention of owner name and/or due date
- Blockers: sentences or bullets mentioning dependencies, blockers, or unresolved issues
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.

weekly-digest-synthesizer is a skill published in the GitHub repository KirKruglov/claude-skills-kit (18 stars, last pushed 1mo ago), licensed MIT. It adds 77 tokens to every session and 1,614 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 2026-09-03.
