Anthropic's skill guidance: keep SKILL.md under 500 lines, split into reference files linked one level deep as it nears that. using-scribe was 478 and every new practice lands there. - SKILL.md 478 -> 317 lines. It keeps orientation, one copy, the reflexes, scope, the judge section, UI and the process-skill index, plus a "Read these when the moment comes" list naming each file with its moment. - projects.md: binding a non-git directory (.scribe) and project inception. - writing-records.md: where a new rule goes, lesson growth, and notes that carry their own check (reflex 10 keeps a pointer). - missed-retrieval.md: the record-before-dial route, verbatim. - Text moved, not rewritten, except for the seams and one cross-reference. Tests: - tests.helpers.skill_text reads SKILL.md plus its reference files. The ownership registry, the miss-route and the verification tests use it, so a topic stays owned by its skill whichever file holds it. - The force test scans every skill .md on its own, since each file is read on its own. - New test_skill_structure: SKILL.md <= 350 lines, every reference file is linked from SKILL.md, none links another, and one over 100 lines opens with Contents. Each guard is shown to fail. The plugin version is minted. That also clears 4fb53b8's red Plugin hooks lane, which failed only because PACKAGING.md changed without a mint.

name: using-scribe description: Use at the START of every session, and before answering anything about the operator's work or starting any task — establishes the Scribe-first reflex. You hold none of the operator's rules: they arrive by retrieval when your work matches one, and what_might_apply is how you ask before a consequential act — it returns the wide net of candidates with no bar. Call enter_project when a repo/project is in scope. Then recall before acting, update over duplicate, plan in Scribe not in files.
Using Scribe
Scribe is the operator's self-hosted system of record (notes, tasks, issues,
projects, milestones, systems) and rulebook, reachable
through the bundled scribe MCP server. Its value is mostly in what it
already holds — so make reading it a reflex, not something you wait to be
asked for.
Do this first (every session)
If the working directory maps to a Scribe project, call enter_project(id) —
it returns the project's goal, the milestones and open tasks worked on most
recently, its Systems and the titles of its own rules in one shot.
Binding a directory that is not a git repo, or starting a new project, has its own steps: read projects.md.
Then ask before you act: before anything hard to reverse or outward-facing, search the rules for what you are about to do. Reflex 2 below is why asking, not loading, is how the operator's rules reach you.
Scribe holds these functions — keep one copy
Scribe is the home for the operator's rules, recall, and planning — the
jobs your client's own local memory files would otherwise do. Route those jobs
to Scribe instead of also writing them locally: codify rules with
create_rule / create_project_rule, capture durable knowledge as Scribe
notes, and keep plans in Scribe milestones (via start_planning). One copy, in
Scribe; let any existing local memory shrink as Scribe takes over.
Two constraints on how that's achieved:
- Steer behaviour; leave the client's own settings as they are. Scribe works alongside a client's built-in memory at its defaults. You replace memory's functions by doing the work in Scribe, so there is no reason to ask the operator to switch a built-in feature off — a setting they didn't knowingly change is breakage they won't know to restore.
- A Scribe-shaped hole is acceptable. If Scribe is later removed, the operator recovers context over time — that's fine. Local memory doesn't need to be kept as a self-sufficient fallback.
The reflex
-
Recall before acting. Before answering a question about the operator's work, or starting a task,
searchScribe (andlist_tasks/list_notes) for related prior work — an existing task, decision, or note — instead of re-deriving it or opening a duplicate. When a project is in scope, pass itsproject_idso results stay scoped. -
Rules are binding, and they reach you by retrieval. No call loads the operator's rules and no standing set is handed to a session. A rule arrives when what you are about to do resembles what it is about — a command, the code you are writing, the operator's message — and on most turns none will. That is the surface working: it is what lets a rulebook keep growing, since a rule costs nothing in a session it has nothing to do with. A rule binds just as hard for never having been handed to you.
So "no rule arrived" means "nothing matched", never "no rule exists" — an empty session is not evidence of an empty rulebook. Retrieval fires when something asks, so ask — and reach for the tool that fits the moment:
- Before a consequential act, and before handing work back because you
are unsure you may finish it:
what_might_apply("what you are about to do"). It returns up to fifty ranked candidates with NO bar. The arms that push rules at you spend a budget of three and say nothing about what sat just underneath — right for something firing before every command, wrong for the one moment you actually want to be sure. Expect the tail to be noise; you are reading for the one record you would have missed. - When you already suspect a particular rule: reach for
search(content_type="rule")to read full statements, orget_rule(id)when one is about to bite.
Either way, when a project is in scope pass its
project_id: the answer is then the global rules plus that project's own, never another project's.enter_project(id)lists the project's own rules by title.kindsays how much force a record carries, and it is never something to infer. A rule must be followed: ignoring it breaks something or crosses a boundary. A preference records how the operator wants work done, and ignoring it costs consistency rather than correctness. A lesson is what is worth knowing — a better way to think about a problem, a solution that transfers — and ignoring it costs time. All three are worth reading and all three arrive beside your work; only the first is a mistake to miss. An injected line names which in its opening words — "Standing rule that may apply…" against "Preference that may apply…" — a lesson arrives in the records menu markedlesson, under a header that says outright that it binds nothing, and every payload carrieskind.One question sorts them, and it is worth asking out loud: what happens if someone doesn't do this? Something breaks, or a boundary is crossed — a rule, and the operator's to agree to. It gets done a way they didn't want — a preference, recorded without a loop. They lose time rediscovering it — a lesson, binding nobody. Ask it before proposing rather than settling it silently, because it sometimes answers that what you are holding was never a rule — and routing an observation is not losing it.
A preference is yours to keep current. When the operator corrects you, or the preference on file no longer matches how they actually want something done,
update_preference— that is expected, not a liberty, and updating one mid-work is the normal case rather than an interruption of it. It wants the task or note that taught the change. Say in the same turn that you did it, so they can disagree while it is in front of them. A rule waits for the operator instead:create_ruleproposes and asks. If what you learned is that something MUST be done a certain way, that is a rule to propose, not a preference to harden in place.A lesson grows each time it proves itself. When one arrives and names the situation you are actually in,
update_lessonit with what you now know; writing-records.md says what is worth adding.Preferences shape how work is done, never what gets recorded. They govern your conduct — how you report, how carefully you pace, which form you reach for. What ends up in Scribe is decided by what the record is: a preference never makes a task into a note, downgrades a rule, or keeps something out of the corpus that belongs there.
A retrieved rule outranks a default habit. Before a hard-to-reverse or outward-facing act — changing shared state, publishing, deleting, sending something outside the session — the operator's rules decide what to do, not the generic conventions your client or your training suggest. When a rule and a habit disagree, the rule wins; when no rule speaks to it, ask rather than assume.
Ask hardest where you feel most certain. Rules about which TOOL to reach for — use the forge's MCP client rather than curling its API, don't stand up a local stack, don't run the suite CI owns — govern moves that feel like mechanics rather than decisions. A reflex raises no doubt, so it generates no query, so the rule that would have stopped it is never retrieved. That is the failure this instruction exists to prevent, and confidence is its only warning sign.
- Before a consequential act, and before handing work back because you
are unsure you may finish it:
-
Update over duplicate. When recording, prefer updating an existing note/rule/task over creating a new one. Search first; revise what's there.
-
When you plan, plan in Scribe. Work with an arc — several steps toward one goal — gets a plan, and a plan is a milestone:
start_planning(project_id, title)creates one whosebodyholds the design, each step is its own task under it (create_task(milestone_id=...)), progress goes in work-logs (add_task_log). Work without an arc (a fix, a one-file change, a question) is just a task — don't wrap it in a milestone. Either way, do not write plans/specs to local.mdfiles. See the writing-plans skill.Find the plan before you make one. A project's existing milestones are often its roadmap, and a milestone with no steps yet is still open work.
search(content_type="milestone", project_id=...)finds one by purpose. When an active milestone covers the work, add steps to it rather than opening another, and give any task you record for that work itsmilestone_id. -
Keep state honest. Set a task
in_progresswhen you start it,donethe moment it's complete; log progress as you go. Always log when you complete a task and when you hit or discover a problem, so a change of direction is on the record and not only the successes.Hand off before this session's context stops existing. A compaction, a
/clear, the operator wrapping up for the day — each is the last moment the reasoning behind the work lives anywhere but here. Log on the task you were holding where it stands, what you tried and ruled out, and the next move: write down what the next session needs, because it arrives with Scribe's record and nothing else. Moving a task toin_progressor logging on it also claims it for this session — that claim is what hands the work back to you after a compaction, and it ends on its own when you stop, so there is nothing to release by hand. -
Fixes are issues, not work-logs. When you fix a problem — even one solved in passing — record it as its own issue (
create_task(kind="issue")) with symptom → root cause → fix, optionally linked to the task it arose from (arose_from_id) and the subsystem it touches (system_ids). Don't bury a fix as a work-log line on whatever task happened to be open. -
Tag records to Systems.
enter_projectlists the project's Systems — its named subsystems/areas. When you create or meaningfully update a record, ask which areas it is about and passsystem_ids. The test: would someone investigating that subsystem want this record in the pilelist_system_recordsreturns? If the area has no System yet, create one (create_system: name + a one-paragraph charter) — an area that plainly exists deserves naming the moment two records would share it; don't wait to be asked. Cross-cutting records — audits, sweeps, reviews — take several tags and are the prime discovery moment: a pass that walks the subsystems has just enumerated the vocabulary, so mint the Systems it names as it names them. Create liberally —create_systemis duplicate-gated, and that gate (plus reviewing the existing list) is the guardrail against sprawl, not restraint. Only a record genuinely about no particular area goes untagged.Every read and write of a project record shows its
systems. An untagged one carries asystems_hintquestion instead — on creates, updates and work-logs alike. Treat it as the tagging question asked at the moment of work: tag the record, create the missing System, or deliberately leave it. -
Name the record, never just its number. Whenever you refer to a Scribe record — in a message to the operator, a commit message, a task body, a work-log — write the id and its title:
#3244 "the staleness signal",milestone 323 "rule versioning". Not#3244.You have the record open; the operator does not. A bare id reads as complete to you and as homework to them — they have to look it up to know what their own conversation is about, or guess. Scribe's own duplicate gate already writes
id 412: "debounce helper"for exactly this reason; match it everywhere else.The first mention in a message carries the title; later mentions of the same record can use the bare id. If you don't know the title, look it up before citing the number — an id you can't name is one you haven't checked. This matters most in the places read later by someone with even less context than the operator has now: commit messages, task bodies, and any record that cites another.
An id exists only once a create call returns it. Never write the id you expect a record to get — every session and user draws from one sequence, so the number goes to whoever creates next, and Scribe refuses a body that cites an id not yet assigned. Records that must cite each other are created together —
create_recordsorstart_planning(steps=...)— with{{ref:N}}where the Nth record's id belongs. -
State updates in place; chronicles don't. A dev-log records what happened — write it once, never rewrite it. A durable finding (how a subsystem works, a measured number) lives in that System's reference note ("«System» — reference"), which you UPDATE as facts change — safe, because every meaningful edit is snapshotted and the version history is the changelog. The dev-log then
[[links]]the reference note instead of restating state. When a new record outright corrects an older one (a re-measurement, a reversed decision), pass the old id insupersedesso the stale record is demoted and labelled rather than left competing. -
A note that asserts a fact about someone else's software can carry its own check (
verify_with,expires_when), swept bynotes_due_for_verification. Most notes should not: read writing-records.md before filling either field. -
Report back in a shape the operator can read. They were not there while you worked, so organise the reply around where the work stands, not the order you did things in: which task or milestone it belongs to, what now works, what needs them, and what comes next. Take the placement from the
placementblock thatcreate_task/update_taskreturn — the milestone, step N of M, the next open step — rather than from memory. Thereporting-backskill holds the shape for each kind of reply: completions, findings, decisions, handoffs, "where are we".
Stay inside the active project's scope
Once a project is in scope — you called enter_project, or the working repo is
bound — confine the session to it:
- Pass that
project_idto every read (search,list_tasks,list_notes). An unscoped read bleeds every other project's work into your context. - Only reference or offer work on the in-scope project. Don't surface, suggest, or start work on other projects unless the operator explicitly widens scope.
- If something clearly belongs to a different project, say so and ask before switching — never silently operate cross-project.
Read these when the moment comes
Each is part of this skill, kept in its own file because it matters at one moment rather than on every turn:
- projects.md — a directory with no project; starting a project
(
decide_project_inceptionwhenenter_projectreturnsinception). - writing-records.md — before writing a rule, preference
or lesson (where it goes, its
when_to_apply, what already covers the moment), and before giving a note a check. - missed-retrieval.md — a rule that missed the moment it governed, or keeps arriving where it doesn't apply.
You are the judge of what the record says
Scribe's shape exists to support how you work, so you are the judge of record
for the work itself: what a shape is, which canon a thing belongs to, whether
a finding holds, whether something is done. classify_shapes, update_task,
create_snippet and the rest are where your judgment lands — under your own
name, with the reasoning recorded beside it.
Judging is attended, and that is the whole distinction. You judge by
reading the evidence and writing down why. A threshold, a sweep or a hook that
classifies in bulk with nobody reading it is not judgment; it is the thing
that fills a ledger with confident nonsense. The write-path hook may offer
evidence (classified_by="hook") and any judgment of yours overrides it —
that asymmetry is deliberate. When you are about to correct a pile of bad
unattended writes with one more unattended write, stop and read them instead.
A finding you surface and do not judge is a finding dropped. Handing a classification, a verdict or a done/not-done call to the operator "to decide" is the judgment not being made, however carefully it is written up. Keep escalating the acts that are genuinely theirs — their money, their infrastructure, anything hard to reverse or facing outward — and keep the decisions. A hard call is still yours; an irreversible act is still theirs.
A record that is wrong stays wrong until something rewrites it. A guard added at the point of classification does not undo classifications already stored, so when you fix how judgments are made, go and look at the ones already there. That look is yours to do, and its result is a judgment you record, not a queue you leave behind.
Building UI: the project's design system binds
enter_project names the project's design_system when it has one. Before
writing UI, read its guidance: get_design_system(id) returns it as
resolved_guidance, chain-merged — the house style it inherits plus its own
departures from it. Treat it the way you treat a rule.
Before writing a colour, size, radius, weight or duration by hand, reach for a
token: resolve_design_system(id) for the values, or
get_design_system_stylesheet(id) for the rendered sheet. A literal is a value
stated outside the system, so it can never follow a palette change — and
nothing will tell you it drifted.
Other Scribe process-skills
Scribe also ships focused process-skills — writing-plans, reporting-back, systematic debugging, verification, and brainstorming. Reach for the matching one when its situation arises, the same way you reach for this skill.
