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 | $0.00007 | $0.00199 |
| Opus 5.5 | $0.00003 | $0.00080 |
| Sonnet 5.5 | $0.00001 | $0.00040 |
| Haiku 4.5 | $0.00001 | $0.00020 |
Grade A, and why
plan_update 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 1mo 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.
This is a copy
97% identical to plan_update — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Update Plan Files
Update the implementation plan files in pr_info/steps based on our discussion.
Instructions
Update the plan by modifying the different files in folder pr_info/steps
Please do targeted changes.
Please log the decisions from our discussion in pr_info/steps/Decisions.md.
Only put those decisions that we discussed, no invented decisions.
(For each decision that you log, consider whether you discussed it with me and when I said so)
Guidelines:
- Make minimal, focused changes
- Preserve existing structure where possible
- Ensure consistency across all step files
- Update the summary if scope changes
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.

plan_update is a skill published in the GitHub repository MarcusJellinghaus/mcp-tools-py (19 stars, last pushed 8d ago), licensed MIT. It adds 7 tokens to every session and 199 once invoked, about $0.0000 per session on Opus 5.5. A static security scan graded it A with 0 findings.
