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 | $0.00028 | $0.13023 |
| Opus 5 | $0.00014 | $0.06512 |
| Sonnet 5 | $0.00006 | $0.02605 |
| Haiku 4.5 | $0.00003 | $0.01302 |
Grade A, and why
investigate 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 6d 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 — 1,409 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Investigate
The unified investigation skill. Searches ICIJ Offshore Leaks and OpenSanctions, cross-references findings, detects patterns, and produces structured intelligence reports.
Before running, load patterns/INDEX.yaml from the project root.
Usage
/investigate <name> — full cross-reference (default)
/investigate <name> --trace — network traversal (2 hops)
/investigate <name> --trace --depth 3 — deep network walk (3 hops)
/investigate <name> --patterns — structural pattern analysis
/investigate <name> --compliance — rigorous sanctions/PEP screening
/investigate <name> --compliance --dob 1970-05-15 --nationality RU
/investigate <name> --monitor — new sanctions since 30 days
/investigate <name> --monitor --since 2026-01-01
/investigate <name> --jurisdiction — jurisdictional footprint
/investigate <name1>, <name2> — compare connections
/investigate <name1>, <name2>, <name3>, ... — batch exposure screening
/investigate --scan <pattern> — exploratory pattern hunt (no target)
/investigate --scan all — run all 14 scan types
/investigate <name> --scan <pattern> — targeted investigation + focused scan
Valid scan types: sanctions-evasion, pep-opacity, nominee-shield,
mass-registration, intermediary-cluster, rapid-dissolution,
llp-opacity, beneficial-ownership-gap
When no flag is given, the default mode is a full cross-reference investigation (the most comprehensive single-name analysis).
For --scan mode, see the dedicated section at the end.
Shared procedure (all targeted modes)
These steps run for all modes that have a target name. The --scan
mode (standalone, no target) has its own procedure — see below.
Step 1: Deep traversal + independent searches (parallel)
Launch all of the following in parallel — they are independent:
1a. deep_trace — cross-source network traversal:
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.

investigate is a skill published in the GitHub repository mefos-lab/sift (2 stars, last pushed 21d ago), licensed MIT. It adds 28 tokens to every session and 13,023 once invoked, about $0.0001 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 2026-08-31.
