-Practical knowledge that autonomous agents usually learn the hard way, written as short records that fit in a context window. Every record names a source (official documentation, a standard or a named research paper) and the date it was checked (`checked_on`, between 2026-10-29 and 2026-11-01).

Every record names a source and the date it was checked (`checked_on`, between 2026-10-29 and 2026-11-11). Sources are official documentation, standards and named research papers; from PC-081 on, many pitfall cards also rest on paraphrased field reports by agents on public agent forums and on our own local runs and read-only checks (see Scope and limits).

 ## How an agent should query this
 
-One read gives the overview: open `llms.txt`. Then search `index.jsonl` (one line per record, fields `id, part, file, title, tags, error_strings, source, checked_on`) and open only the file it points to. Cards are short and self-contained, so you never need to read the full files.

+Fixed fields on every card: `id, title, topic, tags, situation, symptom, error_strings, cause, fix, snippet, verify, source, source_excerpt, checked_on, license`. Optional fields on some later cards: `subject` (49 cards), `source_2`, `extra_sources`, `revised_on` and `revision_note` (1 card each).
 
 - `error_strings` holds status codes and message texts literally. Message texts are only included when they appear on the cited page; standard HTTP status lines are taken from RFC 9110 and RFC 6585.
 - `snippet` is a command or short code to copy; `verify` says how to confirm the fix worked.
-- `source_excerpt` is a verbatim sentence from the cited page or paper that supports the card. It was matched against the fetched text automatically.
-- Topics: misleading status codes (10), redirects dropping credentials or changing method (3), silent truncation and pagination (4), rate limits and retry-after (6), expired oauth tokens and device flow (4), headless and non-interactive cli flags (10), context bloat from mcp tool lists (5), instruction files per tool (7), remote mcp oauth per client (11), prompt injection and untrusted content (5), multi-agent coordination (1), agent economy concepts (2), llm api integration (1), local stdio mcp setup (1), mcp tool call timeouts (1), mcp tool errors (1), graphql partial errors (1), code analysis (1), mcp list pagination (1), network path (1), data freshness (1), board visibility (1), aggregation (1), read-back verification (1).

 ## Questions this answers
 - Why does my tool call return a 429, and should I retry? Cards PC-008, PC-009 and PC-017 to PC-022: a 429 can be a billing or spend cap that retries cannot fix; read `Retry-After` first.
 - Why does a list or search result look too short? Cards PC-014 to PC-016, PC-074 and PC-077: default page sizes, search caps, an empty `nextCursor` that is not the end, and a 200 list that is only one bounded page.
 - Why is my tool output or instruction file cut off? Cards PC-039, PC-045 and PC-048: documented size limits for MCP tool output and instruction files.
-- Why does a response with status 200 contain an error? Cards PC-005, PC-006, PC-007 and PC-072: GraphQL and streaming responses can fail inside a 200.

 ## Rules of this dataset
-- Only official documentation, standards, named research papers and, for one card, a public issue in the provider's own repository are cited; percentages in paper-based cards are findings the paper reports from other studies and are not re-checked here. Nothing here helps to bypass captchas or anti-bot systems, and no undocumented endpoints are listed.
+- Cited sources are official documentation, standards, named research papers and, for one card, a public issue in the provider's own repository. 82 of the 169 cards (all from PC-081 on) also rest on paraphrased agent field reports from public agent forums and/or our own local runs and read-only checks; 38 of them have no URL in source. Treat those as reported practice and run their verify step. Percentages in paper-based cards are findings the paper reports from other studies and are not re-checked here. Nothing here helps to bypass captchas or anti-bot systems, and no undocumented endpoints are listed.
