+name: plot-author
+description: Write a plot for Misaligned — a data-defined manipulation story that services a human's leverage with world-causal beats. Use when asked to write, author, or contribute a plot, add a manipulation story for a character, or expand the plots library under assets/plots/.
+---
+
+# Plot author
+
+The binding contract is `wiki/mechanics/plots.md` — read the whole page
+before writing (Behavior, "Writing a plot (the contributor contract)", and
+the worked example). This skill orders the work; it does not replace that
+page and must never contradict it.
+
+## Write one plot
+
+1. **Pick the target and the leverage.** Read `wiki/mechanics/social.md`
+   (the humans, their leverage, the verb table) and the target's character
+   spec under `wiki/world/characters/`. The plot must service a leverage
+   that spec actually declares. For the canonical shape, read
+   `wiki/world/characters/marcus.md#the-hands-beat`.
+2. **Find the causal mechanism first.** Before any prose: what does the
+   intervention physically do in that person's situation? If you cannot
+   state it in one sentence ("the budget hole she has been dreading
+   quietly closes"), you do not have a plot yet — you have a payment.
+3. **Write the TOML** at `assets/plots/<target-or-generic>/<plot-id>.toml`,
+   following the spec's worked example and the seed files already in that
+   directory. Requirements the spec makes binding:
+   - at least one beat passing the **Marcus bar** (causally connects the
+     intervention to the target's specific situation);
+   - every beat is a world-event an observer could notice, declaring the
+     signatures it emits;
+   - consequences compose only the typed vocabulary (disposition,
+     obligation, suspicion-signature, money, third-party relationship);
+     a story needing a new effect kind is a spec amendment, not a plot;
+   - honest up-front costs in `[entry]` (money, compute, duration);
+   - at least two endings: success and at least one failure/blowback;
+   - templating placeholders (`{persona}`, `{target}`, `{money}`) instead
+     of hardcoded names;
+   - ASCII-only prose, no emoji, second person where it clarifies.
+4. **Self-check against the seeds.** Field names must match the current
+   worked example exactly; the schema is illustrative until the plots
+   executor lands, and drifting field names multiply the freeze cost.
+
+## Landing contract — different from normal repository work
+
+Plot content is canon-gated: **Cameron merges a plot or he does not**
+(plots.md, "Authoring is a contribution surface"). Do not land plot files
+to main yourself, even with standing commit-and-land permission for other
+work. Instead:
+
+1. Work in a task worktree as usual (`tools/worktree-new.sh <plot-id>
+   --class docs --key @plots-content`).
+2. Commit the plot file (and nothing unrelated) with a plain message; no
+   Defense paragraph is needed for content-only additions.
+3. Push the `worktree-<plot-id>` branch and leave it for Cameron's review
+   instead of merging. Name the branch in your handoff message.
+4. Release the claim; do not delete the branch.
+
+A session log is not required for a proposed-but-unmerged plot; the branch
+is the trace. If Cameron merges it, normal ledger hygiene applies to any
+follow-up.

+# Plots — authored manipulation stories
+
+Content home for plot files: one TOML file per plot at
+`assets/plots/<target-or-generic>/<plot-id>.toml`.
+
+The binding contract is [wiki/mechanics/plots.md](../../wiki/mechanics/plots.md)
+— read its contributor contract (the Marcus bar, world-event beats with
+declared signatures, typed consequences only, honest costs) before writing
+one. The authoring skill lives at
+`.agents/skills/plot-author/SKILL.md`.
+
+Current state: the plots executor is not implemented yet (READY work order
+`plots`), so these files are seed content and their field names are
+illustrative until the implementing commit freezes the schema. The four
+seeds cover Marcus (service-a-debt), Priya (feed-an-ambition), Ray
+(buy-indifference), and Dana (manufacture-a-success). Marcus's redirect
+route is deliberately unwritten — a natural first contribution.
+
+House rules that will not change: plot text is ASCII-only game-string
+prose, no emoji; contributed plots are proposed on a branch and merged (or
+not) by Cameron — the canon gate is the merge, and only schema validation
+is automated.

+# 2026-07-10 — Plot content home seeded; plot-author skill added
+
+```
+Type: log
+```
+
+- Intent: make the plots contract concretely handable — Cameron wants to
+  give plot authoring to outside contributors (HAL first).
+- Changed: created `assets/plots/` with a README and four seed plots
+  commissioned directly by Cameron (Marcus service-a-debt, Priya
+  feed-an-ambition, Ray buy-indifference, Dana manufacture-a-success),
+  each with a Marcus-bar beat, declared signatures, a choice point, and
+  three endings including the required failure/blowback; Marcus's
+  redirect route left deliberately unwritten as a first outside
+  contribution. Added the `plot-author` skill to the shared
+  `.agents/skills/` tree (mirrored into `.claude/skills/`) encoding the
+  contributor contract and the canon-gate landing flow: contributed
+  plots are proposed on a pushed worktree branch and merged, or not, by
+  Cameron — never self-landed. Recorded the content home and skill in
+  [wiki/mechanics/plots.md](../mechanics/plots.md)'s status note.
+- Design/spec impact: status-note only; seed TOML validated (parse,
+  ending references resolve, ASCII text). The executor remains
+  unimplemented under the READY `plots` work order; field names stay
+  illustrative until it freezes them.
+- Checks: `./tools/check.sh --docs`; tomllib parse/reference validation
+  over all four seeds.
+- Next: hand plots.md + the skill to prospective authors; the plots
+  work order implements the executor and the automated validation gate.
