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 | $0.00049 | $0.02543 |
| Opus 5 | $0.00024 | $0.01272 |
| Sonnet 5 | $0.00010 | $0.00509 |
| Haiku 4.5 | $0.00005 | $0.00254 |
Grade A, and why
run-performance-improvement-plan 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 — 164 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Run Performance Improvement Plan
Manage a direct report's documented performance gap through a structured, time-bound PIP with clear goals, regular check-ins, and defined success criteria — so both parties know exactly what is expected and what happens if those expectations are not met.
Why This Is Best Practice
Adopted by: The PIP is the standard structured underperformance management tool across enterprise HR systems globally; SHRM's "Managing Employee Performance" knowledge center documents the PIP as the industry-standard mechanism between informal feedback and separation; it is used at Google, Microsoft, Amazon, and all major employers as a legally documented intermediate step; HRCI (HR Certification Institute) includes PIP design and execution as a core competency in the PHR and SPHR certifications Impact: When executed correctly — with clear goals, regular check-ins, and genuine support — studies by CIPD (2020) show approximately 40–50% of employees on PIPs reach the defined performance standard; the primary value of a formal PIP is not termination — it is clarity: many employees on PIPs are succeeding in the wrong role, and the structured clarity of a PIP either surfaces the correct path or creates a legally defensible and humane record if separation becomes necessary; skipping the PIP and proceeding directly to separation exposes the organization to wrongful termination claims in most jurisdictions Why best: Informal feedback alone (give-developmental-feedback) fails for chronic underperformance because it lacks documented timelines, specific measurable standards, and defined consequences; performance reviews document the problem but do not provide a structured remediation path; the PIP bridges the gap between "we've had the conversation" and "we've given this person a real, documented, structured opportunity to succeed"

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-performance-improvement-plan is a skill published in the GitHub repository jeffreytse/grimoire-core (4 stars, last pushed 21d ago), licensed MIT. It adds 49 tokens to every session and 2,543 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.
