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 | $0.00032 | $0.02429 |
| Opus 5 | $0.00016 | $0.01215 |
| Sonnet 5 | $0.00006 | $0.00486 |
| Haiku 4.5 | $0.00003 | $0.00243 |
Grade A, and why
Lease Amendment Reconciliation 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 9d 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.

Lease Amendment Reconciliation
Purpose
Reconcile a base commercial lease against its amendments, side letters, assignments, guaranties, estoppels, and related documents to produce a single working view of what each material lease term currently states. Over the life of a lease, terms are changed, restated, and overwritten across many documents; this skill traces each term through that paper trail so an attorney or transaction team can see, in one place, the latest stated value of each term and the prior values it appears to replace.
This skill produces draft work product for attorney review only. It is not legal advice. It identifies the latest stated term and surfaces conflicts and gaps — it does not decide which document legally controls.
Use When
- A user asks to "reconcile this lease and its amendments," "figure out the current terms," or "tell me what the lease says now after all the changes."
- A lease has one or more amendments, side letters, or assignments and a team needs the controlling terms identified as part of diligence.
- A reconciliation is needed before drafting or reviewing an estoppel, an SNDA, a renewal, or a further amendment.
- An asset-management or transaction team needs a current-terms reference for a lease with a long amendment history.
Required Inputs
- The base lease — uploaded or pasted. Do not reconcile from a description, a partial excerpt, or a prior summary.
- All amendments, side letters, assignments, guaranties, and estoppels — the full document set, uploaded or pasted. If any document is referenced but not provided, it must be noted as missing.
- The party role the reconciliation is prepared for — landlord, tenant, guarantor, lender, buyer, or asset manager.
- The complete document inventory — confirm with the user the full list of documents that exist, so that referenced-but-not-provided documents can be distinguished from documents that do not exist.
If the base lease or any provided amendment text is missing, stop and request it. Do not reconcile a document set you have not been given.
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.
