Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 5 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00124 | $0.03174 |
| Opus 5 | $0.00062 | $0.01587 |
| Sonnet 5 | $0.00025 | $0.00635 |
| Haiku 4.5 | $0.00012 | $0.00317 |
Grade A, and why
flows-external-app-submit 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 8d 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 — 276 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Flows External App Submit
This is step 4 (final) of the Flows app certification flow:
flows-app-brief → build → flows-code-review → flows-design-review → flows-external-app-submit (this skill)
This skill does not rerun any review. It verifies the artifacts from the prior three steps and only then invokes the CLI submit command.
Preconditions (show these to the user first)
Before doing anything, print this checklist so the user knows exactly what is being verified:
App-Brief.mdexists at repo root and all required frontmatter fields are populated.- The latest
reviews/code-review/feedback-round-<N>/code-review-report.mdis committed to git and reportsMust Fix open: 0. - The latest
reviews/design-review/feedback-round-<N>/design-review-report.mdis committed to git and reportsAverage score: X.Xwith X.X ≥ 3.8. - Certification artifacts are committed —
apps submitusesgit archive HEADand silently excludes uncommitted files. - A deploy bundle exists in
.cognite-bundles/and is not older than HEAD.
Step 0 — Air-hatch preflight (offer stubs if reviews are missing)
App-Brief.md is non-negotiable — it captures the value case the certification reviewer reads first. The code and design reviews, however, can be air-hatched with a clear "SKIPPED" status that the reviewer will see and act on. Use this when the user wants to submit without spending the 20+ minutes each review takes.
Probe for each review artifact via git ls-files:
git ls-files 'reviews/code-review/' | grep -q 'code-review-report.md' && echo code_present || echo code_missing
git ls-files 'reviews/design-review/' | grep -q 'design-review-report.md' && echo design_present || echo design_missing
- Both reports present → skip Step 0, continue at Step 1.
App-Brief.mdmissing → continue to Step 1, which fails with the standard "Runflows-app-brieffirst" message. The air-hatch does not cover App-Brief.- Either review missing → offer the air-hatch via

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.
- 8d ago First seen · 276 lines · 124 tokens per session scan A 9d72ff56cab8
flows-external-app-submit is a skill published in the GitHub repository cognitedata/builder-skills (6 stars, last pushed yesterday), licensed Apache-2.0. It adds 124 tokens to every session and 3,174 once invoked, about $0.0006 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.
