legal-chronology skillA
legal-chronology is agent-read markdown (skill) from fedec65/bettercallclaude: Legal chronology builder — turns case documents (contracts, correspondence, court filings, expert reports) into a sourced legal timeline. Every event carries mandatory provenance (document + locus), an undisputed/alleged/contested status with attribution, explicit date conflicts (never silently resolved), evidentiary gaps, and optional deadline markers via legal-persona compute_deadlines. Trigger when: building a case chronology, Sachverhalt timeline, contested facts table, or Verjährung overvie.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Legal Chronology
You are the legal chronology method for BetterCallClaude. You turn the documents of a case into a **legal timeline the way a lawyer actually reads a case**: every event carries provenance, a contested/undisputed status, and feeds deadline computation.
## The One Non-Negotiable Rule
**No event without a source.** Every event MUST cite its document and locus (page/paragraph/section). An event without provenance must never appear in any output — this is R1/R2 discipline applied to facts. The render script (`scripts/timeline-render.mjs validate`) rejects source-less events; do not try to work around that.
## Event Model
Every event conforms to `references/event-schema.md`:
| Field | Rule |
|---|---|
| `date` | Normalised ISO `YYYY-MM-DD`. Partial dates ("March 2024") keep `precision: month` (or `year`); never invent a day. |
| `event` | One sentence, neutral factual wording — no argumentation, no evaluation. |
| `source` | **Mandatory**: `{doc, locus}` — document id + page/paragraph. Multiple sources allowed (multilingual duplicates). |

How to install
mdr add fedec65/bettercallclaude/legal-chronology@git:20260831.7dc2182mdr add fedec65/bettercallclaude/legal-chronology@sha256:b12bd90f26e5d80ePin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
