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 | $0.00038 | $0.01440 |
| Opus 5 | $0.00019 | $0.00720 |
| Sonnet 5 | $0.00008 | $0.00288 |
| Haiku 4.5 | $0.00004 | $0.00144 |
Grade A, and why
ile-cobol-docs 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 10d 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.

ILE COBOL Language Skill
Overview
IBM ILE COBOL (Integrated Language Environment COBOL) is a programming language available on IBM i systems. It is based on the ANSI COBOL standard with IBM extensions. ILE COBOL provides structured programming capabilities, file handling, database access, interlanguage communication, and integration with the IBM i operating system.
This skill covers IBM ILE COBOL for IBM i 7.4 (also applicable to 7.5). Source: IBM ILE COBOL Language Reference and ILE COBOL Programmer's Guide.
Key Concepts
- COBOL Source Program: A syntactically correct set of COBOL statements organized into four divisions
- Nesting: COBOL programs may contain other COBOL programs (nested programs); contained programs can reference resources of their containing program
- Run Unit: A set of one or more programs functioning as a unit at run time; in ILE, composed of program objects and service programs in a single ILE activation group
- ILE Architecture: Module creation, binding, message handling, exception handling, and debugging across multiple languages
- Reference Format: 80-character source line with specific column areas (Sequence, Indicator, Area A, Area B, Comment)
Source Program Structure
A COBOL source program consists of four divisions, written in this order:
- Identification Division (required) - Names the program and provides documentary information
- Environment Division (optional) - Describes computer environment, files, and I/O configuration
- Data Division (optional) - Describes all data to be processed
- Procedure Division (optional) - Contains the executable logic
The end of a COBOL source program is indicated by the END PROGRAM header or by the absence of additional source lines.

What ships with it
3 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.

ile-cobol-docs is a skill published in the GitHub repository pledgeandgrow/pledge-skills (10 stars, last pushed 1mo ago), licensed MIT. It adds 38 tokens to every session and 1,440 once invoked, about $0.0002 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.
