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 | $0.00044 | $0.01659 |
| Opus 5 | $0.00022 | $0.00830 |
| Sonnet 5 | $0.00009 | $0.00332 |
| Haiku 4.5 | $0.00004 | $0.00166 |
Grade A, and why
run-behavioral-interview 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 3d 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 — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Run Behavioral Interview
Conduct a structured behavioral interview using STAR probing (Situation, Task, Action, Result) so that candidate assessment is grounded in evidence of past behavior, not self-reported claims or hypothetical answers.
Why This Is Best Practice
Adopted by: Google uses structured behavioral interviewing across all roles, documented in the re:Work hiring guide; Amazon's entire interview process is built around behavioral questions mapped to Leadership Principles using STAR; McKinsey, Bain, and BCG use structured competency-based interviewing; the US federal government mandated structured behavioral interviewing for civil service hiring in the 1980s Impact: Schmidt & Hunter's landmark 1998 meta-analysis (85 years of selection research) found structured behavioral interviews have a validity coefficient of 0.51 for predicting job performance — roughly 2× the predictive power of unstructured interviews (0.38); the improvement comes entirely from standardization: same questions, same scoring rubric, independent evaluation before group discussion Why best: Unstructured interviews — conversational, improvised, rapport-driven — are dominated by the "halo effect" (one strong impression colors all other ratings), affinity bias (interviewers rate similar candidates higher), and first-impression anchoring; hypothetical questions ("what would you do if...") produce polished, socially desirable answers, not evidence; behavioral questions ask for specific past examples because past behavior under real conditions is the strongest predictor of future behavior in similar conditions

Steps
1. Map questions to competencies before the interview
Each question must map to a specific competency required for the role. Prepare this before any candidate is interviewed — not improvised in the room.
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.

run-behavioral-interview is a skill published in the GitHub repository jeffreytse/grimoire-core (4 stars, last pushed 18d ago), licensed MIT. It adds 44 tokens to every session and 1,659 once invoked, about $0.0002 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.
