  "synopsis": "A naming convention that lets AI agents understand your data without being told what it means, plus a CLI and library for reading Markdown structure and safely editing structured JSON, TOML, YAML, dotenv, and INI documents.",
  "intent": [
    "Encode all semantic information in the field name itself so agents parse structured data without external schemas, documentation, or type systems — _ms/_s/_epoch_ms for time, _msats/_sats/_usd_cents for currency, _bytes for size, _secret for auto-redaction",
    "Define a JSONL output protocol where every line carries a kind discriminator (result, error, progress, or log), a payload field named after that kind, and a trace object for execution context (duration, token counts, cost, data source) — same structure whether the transport is CLI stdout, HTTP response body, MCP tool result, or SSE stream",
    "Provide three output formats via --output json|yaml|plain: JSON is the canonical lossless format, YAML preserves structure with quoted strings and --- separators, plain applies suffix-driven human formatting (epoch_ms → RFC 3339, _bytes → human-readable, _secret → ***, _ms ≥ 1000 → seconds)"

  "mutations": [
    "Read Markdown structure: --input-format markdown exposes a document body as a tree of heading sections carrying 1-based inclusive source line ranges, so a caller can splice exact source without reserializing Markdown or counting UTF-8 bytes",
    "Address an array element by its content instead of its position: a non-numeric path segment resolves against the field named by --slug-field, and matching several elements is an error naming the candidate indices rather than silently taking the first",
    "Accept --slug-field on set and unset as well as on reads, so an address that paths emits can be fed straight back to a write instead of failing on afdata's own output",
    "Refuse --input-format markdown while parsing argv on every mutating verb and on lint, so help and the CLI reference stop advertising a combination whose only outcome is failure",
    "Split three failures out of document_parse_failed: a malformed address is document_invalid_path, a file afdata declines to number is document_source_refused, and a contradictory argument is document_invalid_argument, each keeping the detail that says what to fix",
    "Complete keyed-array editing at the document root, so add and remove work with an empty KEY on a root-level JSON or YAML array"
