What is configure-workspace?

A guide for setting up a workspace for analysing COBOL, a programming language widely used in older business systems. It defines where programs, copybooks, jobs, screen maps, resource definitions, and SQL files are stored, along with analysis settings.

Use it when creating a workspace, changing source paths or file extensions, or adjusting analysis limits and strategies.

It prevents the analysis tool from looking in the wrong folders or treating source files incorrectly.

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	$0.00053	$0.01345
Opus 5.5	$0.00021	$0.00538
Sonnet 5.5	$0.00011	$0.00269
Haiku 4.5	$0.00005	$0.00135

Security

Grade A, and why

configure-workspace 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.

Configuring a Workspace

config.yaml Structure

The workspace config file has three sections: application name, source paths, and settings.

application: CardDemo - Credit Card Management System

source:
  programs:
    - ./source/cbl
  copybooks:
    - ./source/cpy
  jcl: []
  bms: []
  csd: []
  sql: []
  recursive: true
  extensions:
    programs: [.cbl, .cob, .CBL, .COB]
    copybooks: [.cpy, .copy, .CPY, .COPY]
    jcl: [.jcl, .JCL, .prc, .PRC]
    bms: [.bms, .BMS]
    csd: [.csd, .CSD]
    sql: [.sql, .SQL]

output: ./output

settings:
  model: claude-sonnet-4-6
  max_iterations: 5
  n_stable: 2
  confidence_threshold: medium
  strategy: auto
  batch_size: 3
  large_file_threshold: 400
  chunk_threshold: 2000
  staging_dir: ./staging

Source Types

Type	Required	Purpose
`programs`	Yes	COBOL program source files
`copybooks`	Yes	Copybook include files
`jcl`	No	JCL jobs and procedures
`bms`	No	CICS BMS screen map definitions
`csd`	No	CICS CSD resource definitions
`sql`	No	SQL/DDL definitions

Each type takes a list of directories (not individual files). Paths are relative to the workspace root. Set recursive: true to scan subdirectories.

Programs and copybooks can share the same directory -- the extension filter separates them.

Settings Reference

Setting	Default	Description
`model`	(none)	Claude model to use (e.g. `claude-sonnet-4-6`)
`max_iterations`	5	Maximum convergence loop iterations
`n_stable`	2	Stop after N consecutive empty iterations
`confidence_threshold`	medium	Minimum confidence for accepted discoveries
`strategy`	auto	Run strategy: `auto`, `default`, `phased`
`batch_size`	3	Programs per batch in phased mode
`large_file_threshold`	400	Lines above which agents use line-range reads
`chunk_threshold`	2000	Lines above which programs are chunked for analysis
`staging_dir`	./staging	Where chunk files are written

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.

configure-workspace is a skill published in the GitHub repository dsheard/cobol-o-matic (6 stars, last pushed 7mo ago), licensed MIT. It adds 53 tokens to every session and 1,345 once invoked, about $0.0002 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 2026-08-31.
