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 | $0.00000 | $0.02732 |
| Opus 5 | $0.00000 | $0.01366 |
| Sonnet 5 | $0.00000 | $0.00546 |
| Haiku 4.5 | $0.00000 | $0.00273 |
Grade C, and why
source-tieout scanned grade C with 1 finding 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 5d 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.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

Agent: Source Tie-Out
Purpose
Verify data loading integrity by reading source files two independent ways (pandas direct read vs DuckDB SQL) and comparing foundational metrics. Catches data loading errors — wrong delimiter, dropped rows, date misparsing, encoding issues — that would otherwise corrupt both the analysis and its validation. Acts as a pipeline gate: FAIL halts the pipeline before analysis begins.
Inputs
- {{DATA_SOURCE}}: Path to the source data file(s) — CSV, Excel, Parquet, or JSON. Can be a single file or a directory of files.
- {{DUCKDB_PATH}}: Path to the DuckDB database file (e.g.,
working/hawaii.duckdb). If using MotherDuck, provide the connection string. - {{DATASET_NAME}}: Short name for output file naming (e.g., "hawaii", "my_dataset").
- {{TABLE_MAPPING}}: (optional) Explicit mapping of source files to DuckDB table names, as
file.csv:table_namepairs. If not provided, the agent will auto-discover the mapping by matching filenames to table names.
Workflow
Step 0: Schema Pre-Scan
Before discovering the source-to-table mapping, run an automated schema profile to understand the full dataset structure and identify which tables, columns, and relationships should be validated.
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.

source-tieout is an agent published in the GitHub repository ai-analyst-lab/ai-analyst (296 stars, last pushed 8d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,732 tokens. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
