Wiki Teacher

Portfolio-aware project accountability — not a passive reference. /checkin surfaces what genuinely needs attention across several concurrent projects, without turning into either a nag or a dump.

Currently /checkin only. /teach (project-scoped teaching) and /reflect (portfolio-wide mentoring) were part of the original three-command design but are deliberately held back — neither has ever run against real usage or had any real critique pass, unlike /checkin, which has now survived three rounds of scrutiny (a dry-run in the original design, a privacy review, and a from-scratch prose walkthrough that found real gaps). Shipping them alongside a validated /checkin would dress up unvalidated behavior in credibility it hasn't earned. They come back once /checkin has real mileage and an actual felt need surfaces — see knowledge-os/sitrep.md for the full history.

Prerequisites

The obsidian-vault MCP server must be connected. Verify with /mcp before running.

Reference implementation: /checkin's narrowing algorithm — the batch bootstrap, the priority sort, the tie-margin, the cap, and the "what should I work on" fallback — plus portfolio breadth (active count, days since anything last completed) are mechanical enough to script: ${CLAUDE_PLUGIN_ROOT}/scripts/wiki_teacher.py, tested both against synthetic cases and against real parsed files on disk (test_wiki_teacher.py). Check a real run's output against it; treat a mismatch as a bug in the run, not in the script.

Note on commands: /checkin is a natural-language trigger — write it in the chat window. It is NOT a Claude Code CLI slash command.

Principles

1. Portfolio-aware, not single-project. Several concurrent projects are the expected case, not an edge case.
2. Elicit missing signal, don't fabricate it. When priority is needed and undeclared, ask — never default it. A guessed default would just reintroduce the exact ranking problem declaring priority exists to solve.
3. Stateless — the vault is the state substrate. priority, checkin_interval, and status live in the project note's own frontmatter (see wiki-operator's note schema). No teacher-owned tracking file, no computed ease-factor.
4. Growth-mindset tone, not a verdict. Describe what's observed — "3 projects are overdue" is a fact; "you're falling behind" is a verdict. Stick to the fact.

Cadence & session start

At session start, read Maps/_context.md. If last_checkin is not today, check whether any non-paused/complete project is flaggable (see /checkin below). If at least one is, suggest running /checkin — never run it unprompted. If nothing is flaggable, skip silently; a suggestion with nothing to say is worse than no suggestion. Throttled to once per day regardless of how many sessions start.

/checkin

Surface 1–2 projects that genuinely need attention — never a dump of everything overdue. Answers both "what have I neglected" (accountability) and, when nothing's overdue, "what should I work on" — the second half didn't exist in the first build even though this skill's own description already promised that trigger phrase; see compute_checkin()'s explicit_request parameter below.

1. Retrieve all type: project notes from Projects/ only (query_frontmatter with folder: Projects) — Templates/Project carries type: project in its frontmatter and an unscoped query would treat the template as a real project. Exclude any with status: paused or status: complete entirely — the off-ramp.
2. For each remaining project, it's flaggable once days_since(updated) ≥ checkin_interval (default 14 if the field is absent).
3. If one or more flaggable projects have no priority declared, that's the check-in — ask about all of them in one pass, not one per day. Staleness alone can't rank importance — a purely date-derived score puts differently-important projects within noise of each other — but eliciting them one at a time across multiple sessions would make the system nearly useless with several concurrent projects, since nothing can be narrowed until priorities are known. Ask about every priority-less flaggable project together: "3 projects are overdue and don't have a declared priority — quick pass: [[A]], [[B]], [[C]] — high, medium, or low for each?" Write each answer back with patch_frontmatter as it's given. Once every flaggable project has a priority — including ones just answered in this same exchange — proceed immediately to step 4 in the same run. Don't make the user invoke /checkin a second time just to see the result of the bootstrap they just did.
4. Once priorities are known, narrow among flaggable projects: sort by priority (high → medium → low), then by days_since(updated) ÷ checkin_interval as a tiebreaker within a tier. Surface the top item. Include a second only if it shares the same priority tier as the first and its overdue-ratio is within 15% of it — a real tie, not a forced pair. Cap at 2, always. Reference implementation of this exact rule (bootstrap batching, the sort, the tie-margin, the cap) in ${CLAUDE_PLUGIN_ROOT}/scripts/wiki_teacher.py's compute_checkin() — check a real run against it rather than trusting the prose alone.
5. Any flaggable projects beyond the surfaced 1–2 get one passive line: "N other projects are also overdue — say 'show all' to see them."
6. Nothing flaggable, but explicitly asked ("what should I work on," a direct /checkin invocation, not the silent session-start check): don't just say there's nothing to report. Rank all active projects with a declared priority (staleness doesn't gate this — nothing here is overdue) and suggest the highest-priority one, tie-broken by whichever has sat untouched longest. If no active project has a declared priority either, say so plainly and offer to set some — don't force a full bootstrap pass for an idle question with no urgency behind it, but don't guess either. compute_checkin(..., explicit_request=True) implements this exactly — "suggested" or "no_signal".
7. Nothing flaggable, silent session-start check: skip entirely — a suggestion with nothing to say is worse than no suggestion. This is the one case where step 6's fallback does not apply; a proactive suggestion is only useful when actually asked for, never as an unprompted nag.
8. Passively report portfolio breadth: portfolio_breadth() in wiki_teacher.py gives the active project count and days since anything last completed — append one neutral line, e.g. "5 active projects." No framing, no threshold, no "that's a lot" — just the count.
9. After any run, set last_checkin in Maps/_context.md to today.

Output discipline

• Never auto-run /checkin — session start only suggests it.
• Growth-mindset framing: state what's observed as a fact, never as a verdict on the person.
• If MCP tools are unavailable, stop and tell the user — do not simulate vault operations in the conversation.
