SkillsBench contribution workflow. Use when: (1) Creating benchmark tasks, (2) Understanding repo structure, (3) Preparing PRs for task submission.
SkillsBench task authoring — walk a contributor from idea to submission-ready task following CONTRIBUTING.md and the task-implementation rubric. Use when the user wants to create a new SkillsBench task, scaffold a task from an existing workflow (notebook, Excel workbook, document, dataset), convert a prompt or a benchmark item into a SkillsBench task, write skills for a task, or prepare a SkillsBench PR. Pairs with `task-review` (run that as a self-check before submitting).
SkillsBench task PR review — classifies the task track (standard / research / multimodal), runs static policy checks against the track-specific rubric, benchmarks the task across oracle plus Claude and Codex (with and without skills), audits trajectories for cheating and skill invocation, and produces a `pr-N-task-timestamp-run.txt` review report alongside a `prN.zip` bundle of trajectories. Use when reviewing a SkillsBench task PR (by number, branch, or local task path), when the user asks to review a task, run benchmarks on a PR, audit a submission, classify a task as research or multimodal track, or prepare a comment to post on a SkillsBench PR.
Methodology for clause-by-clause review of a contract against a structured deviation policy ("playbook"). Covers how to walk a playbook, locate the matching provision in the contract, apply rule types (max-value, must-be-present, must-be-absent, acceptable-set, must-have-feature), classify the result (ok / risk / reject), choose the prescribed action, and ground each finding in a verbatim excerpt. Use whenever reviewing any contract — NDA, MSA, vendor DD questionnaire, lease, DPA — against a structured rules-based playbook.
Reference for the standard clauses found in commercial non-disclosure agreements (mutual and one-way) — what each clause does, the surface forms it appears in, and how to recognise it in unfamiliar drafting. Use when reviewing, comparing, or extracting provisions from any confidentiality / NDA / mutual NDA / standstill-and-confidentiality agreement.
Read Microsoft Excel (.xlsx) files robustly with `openpyxl` (or `pandas`). Covers multi-sheet workbooks, header rows, empty cells, merged cells, comma-separated list cells, and converting a sheet to a list-of-dicts the rest of your code can consume. Use when a task input or reference document is an `.xlsx` file rather than JSON/CSV.

./prog
-free allows *> comments and free-form source. File names in SELECT
are resolved relative to the program's run directory.
SELECT DETAIL-FILE ASSIGN TO "TRAN.DAT"
ORGANIZATION IS SEQUENTIAL.
For 80-byte fixed-record tapes use ORGANIZATION IS SEQUENTIAL with
RECORD CONTAINS 80 CHARACTERS in the FD. Pad WRITE records to the
required length (e.g. MOVE SPACES TO BAL-REC before populating fields).
When a tape stores sign and magnitude in separate positions (PIC X plus
PIC 9(11)V99), build a signed working-storage value before ADD /
SUBTRACT. Using only the unsigned magnitude in EVALUATE branches is a
frequent bug when debits and credits share the same magnitude field.
COMPUTE … ROUNDED rounds half away from zero in GnuCOBOL (matches the
Python Decimal ROUND_HALF_UP behaviour). Use it when multiplying a
two-decimal amount by a four-decimal rate and storing into a two-decimal
field.
cobc -x -free -Wall -o prog PROG.cblDISPLAY intermediate values for one or two records to confirm the
posting math and any cross-file lookups.
