seed-script

seed-script is a skill for Claude Code from sfc-gh-dflippo/snowflake-dbt-demo. It costs 44 tokens per session (1,400 once invoked), scanned A, original, Apache-2.0.

A preparation step for testing BTEQ scripts, which are Teradata batch SQL scripts. It reads the shell script that launches them to fill runtime variables and stage imported test files.

In plain words
What is it for?
It seeds test YAML for a set of BTEQ scripts, resolves shell variables where possible, and leaves only unresolved values for manual completion.
Why use it?
BTEQ files often receive values from their launcher rather than containing those values themselves. This step reduces missing or placeholder inputs before baseline capture.

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.

Security

Grade A, and why

seed-script 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 2d 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.

Seed BTEQ Script Inputs

Executor for the seedScript task. The CUR declares which shell variables each BTEQ script binds and their kind; the values live in the shell script that sets them before invoking bteq (export UTIL_DB=PROD_UTIL, CFG=${1}.cfg, RUN_DATE=`date +%Y%m%d`) — not in the .btq. scai test seed --bindings-from <shell-script> reads those scripts, pre-fills the binding values, and stages .IMPORT fixtures, so you hand-fill only what genuinely can't be resolved. Capture runs after this against the filled YAML, so leave no placeholder behind. YAML shapes: ../../references/BTEQ_TEST_YAML.md.

Seed the whole BTEQ set in one pass, not one unit at a time: a variable that recurs across scripts is hoisted to the global .scai/settings/test_config.yaml and filled once. Run this the first time any BTEQ unit reaches seedScript — it seeds every BTEQ unit together, so the rest are already done (idempotent; re-runs preserve filled values).

Per binding, the value resolves from the first tier that can supply it: shell-script literal → ${N} arg → capture-time { eval }__REPLACE_ME__ (manual).

Step 1: Ask the user for the BTEQ shell script(s)

Ask for the shell script(s) that set the BTEQ variables and run bteq (e.g. runSqlScript_*.sh), given as file paths or a directory (scanned recursively for *.sh / *.ksh / *.bash; source / . includes are followed when locatable). If a shell script derives values from invocation arguments (CFG=${1}.cfg, . /etc/$1.cfg), also ask for those positional arguments, in order ($1 first).

Collect the path(s) and args only — don't open, read, or trace the shell script to work out which bindings resolve. The seed parses it and reports what it couldn't resolve (Step 3); pre-analyzing here just duplicates that work.

If the user has no shell script, seed without --bindings-from; every value drops to the manual tier (Step 3).

seed-script is a skill published in the GitHub repository sfc-gh-dflippo/snowflake-dbt-demo (33 stars, last pushed 3d ago), licensed Apache-2.0. It adds 44 tokens to every session and 1,400 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 2026-09-10.
