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 | $0.00026 | $0.00673 |
| Sonnet 5 | $0.00011 | $0.00269 |
| Haiku 4.5 | $0.00005 | $0.00135 |
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 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.
How it starts
The opening of the file, as written. The whole thing — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.
- 11d ago First seen · 168 lines · 53 tokens per session scan A 3d40e8e2d130
configure-workspace is a skill published in the GitHub repository dsheard/cobol-o-matic (5 stars, last pushed 5mo ago), licensed MIT. It adds 53 tokens to every session and 1,345 once invoked, about $0.0003 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.
