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 | $0.00249 | $0.00249 |
| Opus 5 | $0.00125 | $0.00125 |
| Sonnet 5 | $0.00050 | $0.00050 |
| Haiku 4.5 | $0.00025 | $0.00025 |
Grade A, and why
ai-plc-session 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.
What it actually says
AI-PLC Session Management
Session Split Triggers
| Condition | Threshold |
|---|---|
| Sub-Layer count | 3+ |
| Total tasks | 10+ |
| Estimated time | 2+ hours |
| Hierarchy depth | 3+ levels |
Context Handoff (new thread)
Required context for new threads:
- AI-PLC system README
- Target scope's intent.yaml
- Target scope's context.yaml
- Parent scope's intent.yaml (if Sub-Layer)
Session Completion Checklist
Before ending a session:
- Check parent scope for remaining Sub-Layers
- Check sibling Sub-Layers for actionable items
- Check pending tasks
- Propose next phase/task
Output Format
Every stage/task completion must include:
- Next Action Protocol — Choice table (A/B/C) + recommendation + copy-paste prompt
- Position Header + Summary — Scope / completed item / artifacts / status
- Progress Dashboard — Completed + next executable tasks only
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.

ai-plc-session is a cursor rule published in the GitHub repository miyatti777/ai-plc (45 stars, last pushed 1mo ago), licensed MIT. It adds 249 tokens to every session, about $0.0012 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 2026-08-30.
