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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 370 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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 | $0.00165 | $0.03876 |
| Opus 5.5 | $0.00066 | $0.01550 |
| Sonnet 5.5 | $0.00033 | $0.00775 |
| Haiku 4.5 | $0.00016 | $0.00388 |
Grade A, and why
rap 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.

RAP (RESTful ABAP Programming Model)
Guide for building transactional applications using the ABAP RESTful Application Programming Model (RAP) in ABAP Cloud.
Clean core context: RAP is the leading programming model for ABAP Cloud development, which is clean core Level A. A custom RAP-based Fiori app for the core SAP Cloud ERP scope is Level A; extending a RAP-based SAP Fiori app via released extension points is also Level A. By contrast, SEGW/BOPF/UI5-based apps and their extensions are Level B. Keep RAP handler code restricted to released APIs to stay at Level A — a single internal object call demotes the whole application to Level C. See the
abap-cloudskill for level details.
Workflow
-
Determine the user's goal:
- Creating a new RAP BO from scratch
- Adding behavior (actions, validations, determinations) to an existing BO
- Writing EML statements to consume a RAP BO
- Troubleshooting RAP-related issues
- Understanding RAP concepts
-
Identify the scenario:
- Managed (greenfield) vs. unmanaged (brownfield)
- Draft-enabled or not
- Numbering concept: early/late, internal/external/managed
- Single entity or composition tree (root + children)
-
Guide implementation following the RAP layered architecture:
- Data modeling (database tables → CDS view entities)
- Behavior definition (BDEF using BDL)
- Behavior implementation (ABAP behavior pool)
- Business service exposure (service definition → service binding)
-
Provide code examples using correct BDL and EML syntax
RAP Architecture Layers
| Layer | Artifacts | Purpose |
|---|---|---|
| Data Modeling | Database tables, CDS root/child view entities | Data persistence and semantic data model |
| Behavior Definition | BDEF (.bdef) |
Declares transactional behavior (operations, characteristics) using BDL |
| Behavior Implementation | ABAP behavior pool (BP_*) |
Implements business logic in handler/saver classes |
| Projection | CDS projection views, projection BDEF | Adapts BO for specific service consumers |
| Business Service | Service definition, service binding | Exposes BO as OData service |
What ships with it
1 file 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.

rap is a skill published in the GitHub repository likweitan/abap-skills (72 stars, last pushed 11d ago), licensed MIT. It adds 165 tokens to every session and 3,876 once invoked, about $0.0007 per session on Opus 5.5. 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.
