What is contentful-export AGENTS.md?

Contribution instructions for contentful-export, a tool that exports data from Contentful, a content management service. They point to the repository's architecture, build instructions, decisions, specifications, and review rules.

Use them when changing the exporter, its command options, type definitions, build output, webhooks, roles, or environment handling. They identify the documents and invariants to check before editing.

They highlight important boundaries, such as editing source instead of generated files and keeping JavaScript options aligned with TypeScript definitions. This helps prevent incomplete or invalid releases.

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	$0.01177	$0.01177
Opus 5.5	$0.00471	$0.00471

Security

Grade A, and why

contentful-export 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 edit dist/ directly. It is a Babel build artifact compiled from lib/. Always edit source in lib/ and run npm run build.
types.d.ts is hand-maintained. It is NOT auto-generated. When changing the public API (options, return type), you must manually update types.d.ts to match.
usageParams.js and types.d.ts must stay in sync. CLI options (yargs definitions in lib/usageParams.js) and the TypeScript Options interface (types.d.ts) define the same option set. Changes to one must be reflected in the other.
Webhooks and roles are master-only. The code explicitly skips webhook and role export when environmentId !== 'master'. Do not change this -- it reflects a Contentful API constraint.
The standalone CLI redirects to contentful-cli. bin/contentful-export prints a notice that the CLI has moved to contentful-cli, then runs the export. Do not add new CLI-only features here.
Integration tests require real Contentful spaces. They are not mocked. CI provides the required secrets via environment variables. Do not commit tokens.
package.json version is 0.0.0-determined-by-semantic-release. Never set a version manually. semantic-release handles all versioning.
Babel target (Node 12) is lower than engines.node (>=22). This is a known inconsistency in babel.config.json. The low target is harmless but confusing.
contentOnly flag is a shorthand. When set, it internally enables skipRoles, skipContentModel, and skipWebhooks. Do not duplicate this logic.
ExO entities Organization entitlement-gated. includeExperienceOrchestration defaults to true. When enabled, six ExO entity types are fetched using the plainClient. If the space lacks the exo_m1 entitlement, each fetch fails silently: the entity array is set to [] and a warning is emitted. The export does not abort. See docs/exo-export.md.
Asset downloads use concurrency of 6. Both download-assets.js and get-space-data.js (editor interfaces) use Bluebird Promise.map with { concurrency: 6 }. Be careful about changing this -- it affects API rate limiting.

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.
