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 | $0.00036 | $0.01364 |
| Opus 5 | $0.00018 | $0.00682 |
| Sonnet 5 | $0.00007 | $0.00273 |
| Haiku 4.5 | $0.00004 | $0.00136 |
Grade A, and why
airtable-filters 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 7d 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.
This is a copy
95% identical to airtable-filters — 16 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Airtable MCP Filters
MCP tools that list or display records from tables or interface pages accept an optional filters parameter, using the same schema.
When querying records from an interface page, these filters are combined with the page's built-in filters using AND.
Schema shape
When no top-level operator is specified, conditions are combined with AND. The first element in a condition's operands array is always a field ID — look up the table's schema to find field IDs before filtering.
Field type categories
- Text-like: singleLineText, multilineText, email, url, phoneNumber, richText, barcode
- Numeric: number, percent, currency, rating, duration, autoNumber, count
- Date: date, dateTime, createdTime, lastModifiedTime
- Single select: singleSelect
- Multiple selects: multipleSelects
- Single collaborator: singleCollaborator
- Multiple collaborators: multipleCollaborators
- Linked records: multipleRecordLinks
- Attachment: multipleAttachments
- Checkbox: checkbox
Computed fields (formula, rollup, lookup) support whichever operators match their result type.

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.

airtable-filters is a skill published in the GitHub repository cass-2003/local-workflow-skill (12 stars, last pushed 2mo ago), licensed MIT. It adds 36 tokens to every session and 1,364 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings.
