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 | $0.00131 | $0.05584 |
| Opus 5 | $0.00066 | $0.02792 |
| Sonnet 5 | $0.00026 | $0.01117 |
| Haiku 4.5 | $0.00013 | $0.00558 |
Grade A, and why
data-cleanup 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 2d 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.

The opening of the file, as written. The whole thing — 357 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Data Cleanup
Two jobs in one skill for the recurring "my CRM is messy" pain (Sidekick's #1 negative-sentiment JTBD):
- Health check (report-only): a scored structural audit of a CRM board — missing-data patterns, stalled groups, abandoned columns, automation gaps, and a 0–100 data-quality score — published as a diagnosis doc. No writes.
- Cleanup (fix): audit the board for data gaps, let the user pick which to fix, then run a bounded, idempotent write loop.
Flow (report): Trigger → Gather → Score (5 strands) → Publish diagnosis doc → offer to fix. Flow (fix): Trigger → Audit → User picks gaps → Plan writes → Execute (bounded, idempotent) → Summary.
Input
- Optional: board name/ID via argument.
- Optional: pre-declared mode (Default / Silent / Proactive).
Output
- α (default): Bounded write loop on the chosen board. Normalizes phone/country/email; can also batch-set owner / source / last-touch / stage when the user explicitly picks those gap types and signals are clean. A
Hygiene fix — <Mon DD>doc lists every change withGenerated by Claudefooter +<!-- claude-skill-id: data-cleanup -->. - β (opt-in): A "before/after" snapshot doc (preserves the prior state for ~30 days, in case a pass over-corrected). User is asked at Step 4.
- Proactive extension: Out of scope — data-cleanup is already a write skill; proactive doesn't change its behavior. Default mode + batched confirm is the only write surface.
Knowledge
- Gap taxonomy + audit rules (§ Step 3).
- Normalization recipes (§ Step 5).
- Shared artifact conventions (§ Shared patterns).

Forcountrycolumns, use:change_multiple_column_valueswithcolumn_values: {"<country_col_id>": {"countryCode": "<ISO2>", "countryName": "<name>"}}. Do not freeform the mutation type — only this shape is supported for country columns.
What ships with it
1 file 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.

data-cleanup is a skill published in the GitHub repository mondaycom/mcp (421 stars, last pushed 6d ago), licensed MIT. It adds 131 tokens to every session and 5,584 once invoked, about $0.0007 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.
