feat(task-format): new skill v0.1.0 — poller task-block format reference

Public reference for the on-disk .tasks/STATUS.md block format the autonomous
poller parses: header regex, status emoji, and the **Weight:** / **Notify:** /
**Requirements:** fields. Ships with factory where the internal wiki and MCP
source can't reach. Distinct from delegate-task (MCP-tool delegation) and
using-tasks (board mechanics).

Authored via superpowers:writing-skills TDD:
- RED: 3 baseline subagents w/o skill — 2/3 used ###/bullet headers the parser
  cannot recognize as a task, 2/3 omitted **Weight:** (invented risk/tier/
  claimable-by), 2/3 put notify in prose, 1/3 used 🟢 for a ready task.
- GREEN: 2 fresh subagents w/ skill — both parser-valid, incl. correct
  **Weight:** needs-human for the critical-infra scenario.
- REFACTOR: no new format loopholes.

Ground truth verified vs live source (status-md.ts parser, claim.ts gate,
fleet-router.js routing): missing Weight finds no backend tier -> poller parks
to blocked, so Weight is operatively required for pickup.

Closes [create-task-format-for-poller-skill]. Install to ~/.claude/skills +
hermes mapping deferred as follow-up.

 ## [2026-06-09] decision | using-tasks-session-break — `using-tasks` 1.1.0→1.2.0 (MINOR): added the `session_break` marker. Task author sets `session_break: true | "<hint>"` in task frontmatter (mirrored as `**Session break:**` on the local board); after the task closes 🟢, before `tasks_claim_next`, an autonomous agent prints the verbatim line `🔚 SESSION BOUNDARY — [slug] закрыта. Рекомендую завершить текущую сессию. Следующий трек: [value | "см. STATUS.md"]` and stops instead of chaining the next task. Absent → behaviour unchanged. Enforced in Task completion step 6 + Rules bullet + format docs. Marker not heuristic: the stop-point is an authoring choice, not a runner guess.
 ## [2026-06-09] review | using-tasks-status-archival v1.3.0 — VERDICT PASS 3/3 (using-tasks-status-read-perf-review). Criterion «ориентация через `tasks_get_status`, не Read» is satisfied by a **validated deviation**, not a literal swap: re-verified against the live tool schema that `tasks_get_status(target_project, slug)→{status, found}` takes a required slug and returns ONE task — it cannot enumerate the board, so it cannot drive orientation; the implementer correctly rejected the impossible instruction and fixed the real problem (bloat→archival). No regression: orientation still reads local STATUS.md (Session start §2) and the «what's next» flow still reads the board — change is purely additive. Archival rule clear & complete (≥10 threshold, two trigger points, monthly append-only archive, verbatim blocks, dedicated commit, cross-referenced). One informational non-blocking note: this repo's own STATUS.md (>10 🟢) would itself trip the rule — dogfooding tracked separately as tasks-board-cleanup-2026-05. No follow-up tasks. Verdict appended to concepts/using-tasks-status-archival.md.
 ## [2026-06-09] decision | delegate-task-review-weight — `delegate-task` 0.2.2→0.2.3 (PATCH): Step 5 (paired `<slug>-review` task) now sets an explicit `weight`, inherited from the impl-task with a `needs-claude` floor (impl `needs-human`→review `needs-human`; `needs-claude`→`needs-claude`; `cheap-ok`→`needs-claude`). Root cause of commit `c0af151` ("add Weight: needs-claude to 4 review tasks — reconciler was skipping them"): the authoring skill omitted `weight` on review tasks, making them invisible to fleet routing. Floor (not pure inheritance) chosen to stay internally consistent with the skill's own "What NOT to do" bullet that forbids `cheap-ok` for review tasks — a `cheap-ok` impl would otherwise propagate a forbidden `cheap-ok` review. Added a What-NOT-to-do bullet against weightless review tasks. Concept page concepts/delegate-task-review-weight.md + index. TDD N/A (markdown policy artifact).
+## [2026-06-11] decision | task-format — new skill v0.1.0: public reference for the `.tasks/STATUS.md` task-block format the autonomous poller parses. Motivation: the field rules (`**Weight:**` capability/cost tier, `**Notify:** <owner>/<repo>` inbox target, header regex, status emoji) lived only in internal sources (`projects-meta-mcp/src/lib/status-md.ts` parser + `status-md-writer.ts` + `.common/.wiki/concepts/agents-task-runner-ops.md`); skills ship with `factory` to external users, the wiki/MCP-source don't. Scope kept distinct from delegate-task (creates tasks for others via `tasks_create`, the tool emits the format) and using-tasks (board claim/close mechanics) — task-format is the byte-level field reference for hand-edited blocks. Ground truth verified against source: header `/^##\s+(\S+)\s+\[([^\]]+)\]\s+—\s+(.+)$/u`; Weight ∈ {cheap-ok, needs-claude, needs-human}; claim gate excludes only `needs-human` (`claim.ts`), but a *missing* Weight finds no backend tier (`fleet-router.js` resolveBackend) → poller parks to 🔵 blocked, so Weight is operatively required for pickup. TDD per writing-skills: RED = 3 baseline subagents w/o skill (2/3 used `###`/bullet headers the parser can't recognize, 2/3 omitted Weight inventing `risk`/`tier`/`claimable-by`, 2/3 put notify in prose, 1/3 used 🟢 for ready); GREEN = 2 fresh subagents w/ skill, both parser-valid incl. correct `needs-human` for the critical-infra scenario; REFACTOR = no new loopholes. Reference skill ~900 words (loads only when authoring a task block). Concept page concepts/task-format-design.md + index. Not yet installed to `~/.claude/skills/` or added to hermes mapping — deferred follow-up (mirrors using-system-snapshot deployment-scaffold note).
 ## [2026-06-09] decision | using-markitdown-cli-migration — `using-markitdown` 1.0.0→1.0.1 (PATCH): rewrote the skill from the Docker-based `mcp__markitdown__convert_to_markdown` MCP tool to the native `markitdown` CLI (v0.1.6, on PATH). Tool block now `markitdown <path|url>` → stdout (or `-o file`); removed the whole "Docker-mount caveat (READ FIRST)" section (host→container `file://` translation + `[Errno 2] /c:/Users/...` symptom are gone — CLI sees the full host FS). Updated the ingest pattern (use `-o` straight into `.wiki/raw/`), the gotchas table (`command not found` → check `markitdown --version`, install `pip install markitdown[all]`; dropped the MCP "tool not available / ToolSearch" row), and the contrast-table header (CLI, not MCP). Description frontmatter (the WHEN-to-use triggers) left unchanged. Container decommission: the task's literal `docker stop/rm markitdown-mcp` had no target — no container is named that; the MCP spawns anonymously-named containers from `markitdown-mcp:latest` per session (3 had piled up). Removed all by image ancestor (`docker rm -f $(docker ps -aq --filter "ancestor=markitdown-mcp:latest")`), verified none remain. Left the `mcpServers.markitdown` entry in `~/.claude.json` untouched (out of scope; a container will respawn next session until it's deregistered — flagged as a follow-up).
