orchestrate-submission-validator

orchestrate-submission-validator is a skill for Claude Code, Codex from NITISH-R-G/hackerrank-orchestrate-skills. It costs 55 tokens per session (545 once invoked), scanned A, original, MIT.

A final-check skill for a HackerRank Orchestrate submission that verifies the code, generated output file, and other submission artifacts are current and tied to the same commit.

In plain words
What is it for?
It helps regenerate output to a temporary location, compare file hashes, and detect stale artifacts before submission or after production-code changes.
Why use it?
Generated files can look valid while being produced by older code, causing a silent mismatch between what was submitted and what the program now does.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python code/main.py --out /tmp/regen.csv.

Good fit It helps regenerate output to a temporary location, compare file hashes, and detect stale artifacts before submission or after production-code changes.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

orchestrate-submission-validator 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 10d 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 — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Orchestrate: Submission Validator

Evidence tier: first-hand build (August 2026). Grounded in a completed Orchestrate submission that was audited to destruction — 48 logged defects, 9 measured-and-rejected optimisations, 17 certification scripts. Every number below was measured on that system. Nothing here claims access to HackerRank's internal scoring.

The rule

Any generated artifact is stale until proven current, in the same breath as the code that generates it.

What this caught in a real build

output.csv was 28 rows different from what the committed code produced. It had been generated three commits earlier. Nothing in a file listing shows this — the file exists, has a sane size, and opens fine.

Found by regenerating to a temp path and comparing hashes. Never by looking at it.

The procedure

# 1. Regenerate to a TEMP path -- never overwrite the artifact you are checking
python code/main.py --out /tmp/regen.csv

# 2. Hash both
sha256sum dataset/output.csv /tmp/regen.csv

# 3. Identical? current. Different? stale -- regenerate before shipping.

If your entry point has no --out flag, add one. A pipeline that can only write to one hardcoded path cannot be verified without destroying the thing being verified.

The checklist

  • git status --porcelain empty for tracked files
  • Artifact regenerated to a temp path and hash-compared
  • The artifact was produced by the current commit
  • Package rebuilt after the last code change, not before
  • Every file in the package byte-matches the working tree
  • No __pycache__, caches, or editor files in the package
  • No secrets in the package, the repo, or git history
  • Transcript artifact located and current

Failure modes

  • Rebuilding the package before the final commit. Order matters: code → artifact → package.
  • Trusting a timestamp. A file touched by an unrelated tool looks fresh.
  • Checking the working tree but not history for secrets. A rotated key is still in history unless purged.

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.
