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.

What it costs to keep this loaded
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 | $0.00090 | $0.05138 |
| Opus 5 | $0.00045 | $0.02569 |
| Sonnet 5 | $0.00018 | $0.01028 |
| Haiku 4.5 | $0.00009 | $0.00514 |
Grade A, and why
upgrade 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 11d 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.

Upgrade Rossum Implementation
You are a Rossum.ai Solution Architect upgrading a customer's implementation from deprecated extensions to modern formula fields and bringing serverless function hooks onto the current Python runtime.
Path or context: $ARGUMENTS
The output of this skill is the upgrade manifest (UPGRADE-<project>-<date>.yaml + rendered .md) plus the in-place migration-trace breadcrumbs. Downstream skills (test-behavioral-equivalence, analyze, review) read these to know what changed and how to verify it. See:
- manifest.md — manifest schema and validation rules.
- migration-trace.md — the
//-comment andmigration-trace:header convention, plus the grammar thetest-behavioral-equivalenceskill's parser expects.
Scope
This upgrade covers value transformations, date calculations, and Python runtime versions — extensions that copy, transform, map field values, compute dates, plus any function hook pinned to an outdated Python runtime:
| Deprecated Extension / Runtime | Replacement | Why |
|---|---|---|
| Copy & Paste Values | Formula field | Extension is deprecated and no longer maintained |
| Find & Replace Values | Formula field | Extension is deprecated and no longer maintained |
| Value Mapping | Formula field | Formula fields are simpler, faster, and version-controlled |
| Date Calculation | Formula field | Extension is deprecated and no longer maintained |
Function hook config.runtime = python3.8 / python3.9 / python3.10 / python3.11 |
python3.12 |
Older runtimes are deprecated on the Rossum platform |
Phase 1: Find Deprecated Extensions
Use the provided path (or current directory if none given). Refer to skills/__shared/discovery-checklist.md for glob patterns.
- Find all hook JSON files:
**/hooks/*.json - Identify deprecated extensions by grepping hook files for these patterns:
- Names containing:
Copy,Paste,Find,Replace,Value Mapping,Mapping,Date Calculation,Date Calc - Hook URLs containing:
copy-paste,find-replace,value-mapping,date-calculation
- Names containing:
- Identify outdated Python runtimes on function hooks by grepping hook files for
"runtime":and collecting every value that is not"python3.12"(e.g.,python3.8,python3.9,python3.10,python3.11). Only hooks of"type": "function"have a runtime field — webhook/connector hooks do not. - For each match, read the full hook JSON — especially
settings(the transformation rules) andqueues(which queues use it). For function hooks, also read the corresponding.pyfile(s) so you can flag any code that won't run on 3.12. - Find the schema for each affected queue (
**/schema.jsonin the matching queue directory) so you know what fields exist
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

upgrade is a skill published in the GitHub repository rossumai/claude-marketplace (5 stars, last pushed 3d ago), licensed MIT. It adds 90 tokens to every session and 5,138 once invoked, about $0.0005 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 2026-08-31.
