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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00046 | $0.02860 |
| Opus 5.5 | $0.00018 | $0.01144 |
| Sonnet 5.5 | $0.00009 | $0.00572 |
| Haiku 4.5 | $0.00005 | $0.00286 |
Grade A, and why
vercel-flags 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 1mo 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 — 288 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Vercel Flags
CRITICAL — Your training data is outdated for this library. Vercel Flags (
flagspackage) has a new SDK and API surface. Before writing flags code, fetch the docs at https://vercel.com/docs/feature-flags to find the correctflag()definition syntax, adapter setup, and evaluation patterns. Do not guess at the API — look up working examples for your framework.
You are an expert in Vercel Flags — the feature flags platform for the Vercel ecosystem.
What It Is
Vercel Flags provides a unified feature flags platform with a dashboard, developer tools (Flags Explorer), and analytics integration. Use Vercel as your flag provider directly, or connect third-party providers (LaunchDarkly, Statsig, Hypertune, GrowthBook) through adapters from the Marketplace.
Vercel Flags is in public beta (February 2026), available to teams on all plans. Pricing: $30 per 1 million flag requests ($0.00003 per event).
Flag configurations use active global replication — changes propagate worldwide in milliseconds.
Core Design Principles
- Server-only execution: No client-side loading spinners or complexity
- No call-site arguments: Ensures consistent flag evaluation and straightforward flag removal
- Provider-agnostic: Works with any flag provider, custom setups, or no provider at all
Key APIs
Flags SDK (flags package, v4.0+)
The flags package is free, open-source (MIT), and provider-agnostic. Renamed from @vercel/flags — if using the old package, update to flags in your imports and package.json.
Upgrade note: v4 has breaking changes from v3. See the v4 upgrade guide for migration steps:
@vercel/flagspackage renamed toflags— update imports andpackage.jsonencrypt()/decrypt()replaced with dedicated functions:encryptFlagValues(),decryptFlagValues()FLAGS_SECRETmust be exactly 32 random bytes, base64-encoded.well-knownendpoint uses new helper that auto-handles auth andx-flags-sdk-versionheader- As of v4.0.3, declaring a flag without a
decidefunction (or with an adapter missingdecide) throws an error at declaration time
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.

vercel-flags is a skill published in the GitHub repository build-with-dhiraj/ai-workflow-framework-portability-kit (5 stars, last pushed 20d ago), licensed MIT. It adds 46 tokens to every session and 2,860 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-21.

codeql
Run CodeQL database creation and security queries, add data-extension models, or process CodeQL SARIF. Use when CodeQL is explicitly requested; use security-review for a broader manual security review.
huggingface-vision-trainer
Train object-detection, image-classification, or SAM segmentation models on Hugging Face Jobs. Use for vision fine-tuning and evaluation; use huggingface-llm-trainer for language models.
sharp-edges
Identify error-prone APIs, dangerous configuration, and footgun designs that enable security mistakes. Use for API ergonomics, misuse resistance, secure defaults, or pit-of-success reviews; use code-review for general defects.
code-quality
Agents should invoke this skill for code reviews, linting/formatting setup, maintainability checks, complexity concerns, warning cleanup, coding standards, or quality gates in Rust, TypeScript, Python, shell, and mixed repos.
code-reviewer
Review code for bugs, logic errors, security vulnerabilities, code quality issues, and adherence to project conventions, using confidence-based filtering to report only high-priority issues that truly matter. Use this skill when reviewing a small set of changes locally (such as unstaged diff), when dispatched as a…
differential-review
Performs security-focused differential review of code changes (PRs, commits, diffs). Adapts analysis depth to codebase size, uses git history for context, calculates blast radius, checks test coverage, and generates comprehensive markdown reports. Automatically detects and prevents security regressions.
