What is contentful-import AGENTS.md?

A guide for developing Contentful Import, a project whose detailed purpose is not included here. It points agents to the repository overview, architecture, build instructions, decisions, specifications, and review rules.

Finding development guidance, reviewing design decisions, and respecting rules for exports, webhooks, locales, and feature-gated tags.

It directs agents to the right sources of project context and records constraints that could otherwise cause integration or compatibility errors.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00984	$0.00984
Opus 5.5	$0.00394	$0.00394
Sonnet 5.5	$0.00197	$0.00197
Haiku 4.5	$0.00098	$0.00098

Security

Grade A, and why

contentful-import AGENTS.md 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 2mo 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.

Sharp Edges & Invariants

Never change the dual-export pattern in lib/index.ts without understanding the cli-table3 / esModuleInterop constraint. The file exports via both export default and module.exports = ... simultaneously — this is intentional. See ADR 001.
Webhooks can only be imported to the master environment. The pushToSpace task skips webhook creation for any non-master environmentId — this is a Contentful API constraint, not a bug.
The default locale of the source and destination space must match. assertDefaultLocale throws a hard error if they differ. Do not attempt to work around this — it is a fundamental Contentful space invariant.
Tags are feature-gated. If the destination space returns a 404 on getTags, destinationData.tags is deleted and all entity metadata is stripped by transformers. Never assume destinationData.tags is present.
Do not run npm install with scripts enabled. .npmrc sets ignore-scripts=true for security. This is intentional.
dist/ is generated — never hand-edit it. Run npm run build to regenerate. dist/ is committed only at release time via CI.
Rate limit is enforced via p-queue. All CMA calls go through requestQueue. Do not make direct environment.* or space.* calls outside the queue — this bypasses rate limiting and risks 429 errors.
Import order matters in pushToSpace. Locales → Content Types (published) → Editor Interfaces → Tags → Assets → Entries → Webhooks. This order is required by CMA API constraints (entries can't reference unpublished content types). Do not reorder task steps.
Integration tests create real Contentful spaces. They require org-level credentials (MANAGEMENT_TOKEN, ORG_ID) and will fail without them. Never run them without credentials set.

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.
