A set of automatic rules for using COBOL Bridge tools when working with COBOL, a programming language common in older mainframe systems. It covers code parsing, business-rule extraction, migration planning, testing, and effort estimation.

It is for understanding COBOL programs, finding their business rules, planning migrations to another technology stack, creating parallel-run tests, and estimating migration complexity.

It helps keep legacy-modernisation work in one workflow instead of requiring the user to remember which tool to invoke for each COBOL task.

Token cost

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	$0.00171	$0.00171
Opus 5.5	$0.00068	$0.00068

Security

Grade A, and why

cursorrules 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 2mo 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.

What it actually says

COBOL Bridge (Legacy Modernization) MCP - Auto-trigger Rules

When the user asks about COBOL, legacy modernization, mainframe migration, banking IT, COBOL parser, use cobol-bridge-mcp tools:

parse_cobol_program: Parse COBOL source — extract paragraphs, divisions, file IO
identify_business_rules: Extract business rules from procedure division logic
plan_migration: Generate phased migration plan COBOL → target stack
generate_test_harness: Generate equivalence test harness for parallel run
estimate_complexity: Estimate migration effort (cyclomatic complexity + IO surfaces)

Install: pip install cobol-bridge-mcp

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.
