Xberg is a document-intelligence engine that reads files, URLs, archives, and source trees and extracts text, metadata, images, tables, and structured data, with additional code-language understanding. Developers use it through language bindings, a command-line tool, REST API, or MCP server, and the catalogue entries support those integrations.
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.

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 | $0.00035 | $0.00789 |
| Opus 5.5 | $0.00014 | $0.00316 |
| Sonnet 5.5 | $0.00007 | $0.00158 |
| Haiku 4.5 | $0.00003 | $0.00079 |
Grade A, and why
e2e-fixtures scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
xberg E2E Fixtures
One JSON object per file under fixtures/<dir>/. The directory is the default category; an explicit category field
overrides it and names the generated test file (e.g. fixtures/plugin_api/list_reranker_backends.json sets
reranker_backend_management, so its Python test lands in e2e/python/tests/test_reranker_backend_management.py).
- Fields:
id(unique snake_case, becomes the test name),call,description,docs(topic,title,description,side_effects),assertions; optionalcategory,tags,input,config,args,skip. call:extract(most fixtures),extract_batch,pdf_page_count,extract_with_external_redaction, and the plugin-registry calls (list_*,register_*,unregister_*,clear_*for OCR, embedding, tokenizer, reranker backends, renderers, validators, post-processors;ocr_backend_supports_language).input:extract_input(kind: "uri"with$mock_url/..., orbytes+filename+mime_type) plusmock_responses(path,status_code,headers, optionalmethod, and a body:body_fileresolved against aresponsessubdirectory offixtures/(none exists yet), thenfixtures/itself, so../test_documents/...is the in-repo submodule; orbody_inline). Batch calls takeinputs. A bytes input can also sit at the top level ofinput(kind: "bytes",bytes,filename,mime_type) withoutextract_input. Other calls take call-specificinputfields (pdf_bytes/password,findings_json, registryname/backend); copy an existing fixture of that call.- Assertion types:
not_error,error,equals,min_length,count_min,count_equals,contains,contains_any,contains_all,not_contains,not_empty,greater_than_or_equal,less_than_or_equal. Examplefield:results[0].mime_type. - Assertion shape and generation: the shared
e2e-generationskill. skip:{languages: [...], reason: "..."}.- Directories:
smoke,extract,batch,contract,error,format_specific,pdf,code,url,plugin_api,registry,summarization. Field-only categories (all underplugin_api/):ocr_backend_management,embedding_backend_management,tokenizer_backend_management,reranker_backend_management,renderer_management,validator_management,post_processor_management. fixtures/repros/holds repro assets (PDFs, configs, READMEs) andfixtures/images/a test image; neither holds e2e fixtures.
Copy the nearest existing fixture of the same call rather than writing one from this list.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

e2e-fixtures is a skill published in the GitHub repository xberg-io/xberg (9,464 stars, last pushed today), licensed MIT. It adds 35 tokens to every session and 789 once invoked, about $0.0001 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 2026-10-28.
