 ## What it does
 
 One or two plain-language paragraphs. Lead with the skill's one-sentence job, then state the **defining constraint** — the single fact that makes this skill behave differently from the obvious default (for `to-spec`: it does not interview the user again, it synthesises what is already known). Write it as a plain declarative sentence — never a labelled aside like "The defining constraint:" or "The key thing:"; the formula reads as filler. This line is the most valuable on the page; never omit it.

 The single non-negotiable: **surface the skill's leading word / defining idea** — `tight` feedback loop, `deep module`, throwaway-code-answers-a-question, red-green. It pays off twice: the reader learns what the skill *is*, and learns the word they'll later think with to *reach for* it.
 
-## Common questions
-
-The questions readers really ask about this skill, each in bold with the answer in the lines beneath it — no sub-headings.
-
-Every question here is one someone asked. That is the section's whole value: a page with three observed questions beats one with eight plausible ones, because an invented question teaches the reader nothing and reads as filler. So go and find them before you write any:
-
-- **The wiki.** If `~/repos/matt/personal-wiki` exists on this machine, it is the richest source there is. Its `wiki/audience/` area is organised around what the audience wants, discusses, and **is confused by** — read `wiki/index.md` first for the registry of pages, then the pages bearing on this skill. Every page carries `sources:` linkbacks to the original X, Discord, GitHub, and email threads; the wiki is a secondary source, so quote the asker's own question rather than the wiki's summary of it. Skip this bullet where the directory does not exist.
-- **This repo's issues.** `gh issue list --repo mattpocock/skills --search "<skill-name>" --state all`. A question filed twice is a question the page owes an answer to.
-- **`CHANGELOG.md`.** Anything renamed, moved, or behaviourally changed generates a "where did it go?" that the page has to answer.
-
-Order them by how often each comes up, sharpest first, and say the unflattering thing where it is true — a very long grilling session usually means the scope was too big; a model asked to write its own skill produces something verbose. Omit the heading where the hunt turns up nothing.
-
 ## It's working if
 
-A few bullets naming what the reader sees when the skill is doing its job. The bar on each is that the reader can check it without opening `SKILL.md` — a signal in their own work, or in the trace in front of them. "The document gets shorter as it gets better" passes; "the library section is byte-identical to `template.sh`" is a compliance check on the skill's internals wearing this section's name. Include it wherever the tells are crisp; omit the heading where they stay vague.
+Optional. A short, checkable list of the observable signals that tell the reader the skill is actually doing its job — what they should see when it fires, and by absence when it hasn't. Include it when a skill has crisp tells (e.g. `to-spec` writes without re-interviewing you; a leading word reappearing in the trace); omit the heading when the signals are vague.

+Rewrite the `writing-for-agents` docs page around what people actually get wrong.
+
+The old page was a table of contents for the skill: the two loads, then a bullet per lever. It answered none of the questions the rename and the AMA threads have been generating for months — where `writing-great-skills` went, whether the agent or the human is doing the writing, why you shouldn't just ask Claude to write the skill for you, and how you know when a document is done.

+The rewrite keeps the levers to one compact list and spends the page on the judgement calls instead:
+
+- **The defining constraint is now stated up front** — the default move is deletion, not explanation, because the reader has already read everything. This is also the answer to "why not let the model write it", so it leads.
+- **The scope is stated as a test**, not a list: does an agent read this document and act? Skills, `AGENTS.md`, specs, tickets and runtime prompts all pass it.
+- **A "Common questions" section** answers the nine highest-volume ones directly, including the rename, the "streamline" failure where an agent trims for length and cuts behaviour, whether to rewrite documents per model, the skill that only works on the one task it was built from, and the leading-word question from non-native English speakers.
+- **"It's working if"** added, led by the sharpest signal: the document gets shorter as it gets better, and duplication is the most reliable sign it was never tested.
+- **`Where it fits`** says plainly that it has no chain neighbour: it sits underneath the set rather than beside one skill, and the documents the other skills leave behind are the text it governs.

 ## What it does
 
 `code-review` reviews the diff between `HEAD` and a fixed point you supply — a commit, branch, tag, or merge-base — along two separate axes: **Standards** (does the code follow this repo's documented conventions?) and **Spec** (does it implement what the originating issue or spec asked for?). It runs each axis as its own parallel sub-agent and reports them side by side. It never merges or re-ranks the two sets of findings — keeping them separate is the whole point, because a change can pass one axis and fail the other, and a single blended verdict lets one mask the other.

+## The levers
 
-- **Context pointers** — the reference held in context that names out-of-context material and encodes when to reach it. A skill description and an `AGENTS.md` line pointing at a doc are the same object; the pointer's *wording*, not its target, decides when and how reliably the agent reaches through it.
-- **Information hierarchy** — the ladder from in-file step, to in-file reference, to disclosed reference behind a pointer. **Progressive disclosure** is the move down that ladder so the top stays legible; **co-location** decides what sits beside each piece once placed.
-- **Completion criteria** — the clarity and demand of each step's done-condition, and the **legwork** it drives; the defence against **premature completion**.
-- **Leading words** — a compact concept already in the model's pretraining (*tight*, *red*, *tracer bullet*) that the agent thinks with while running the document; hunt restatements a single word can retire.
-- **Pruning** — single source of truth, relevance, and the no-op test applied sentence by sentence, against **sediment** and **sprawl**. Single source of truth reaches past the document into the environment: a doc restating what's already in `package.json`, a config file, or `--help` output is a **cache** of a lookup that was never expensive, and it's the copy that goes stale. Cache what the agent can't find by looking — the unwritten convention, the reason behind a choice.

+- **Pruning** — single source of truth, relevance, and the no-op test applied sentence by sentence, against **duplication**, **sediment** and **sprawl**.
+
+## Common questions
+
+**Where did `/writing-great-skills` go?**
+It is this skill, renamed in v1.1. Practitioners were already pointing it at `AGENTS.md`, docs, specs, tickets and runtime prompts long before the name caught up; structure, leading words and pruning turn out to be the craft of any text an agent reads. There is no alias — reinstall under the new name.
+
+**"Writing for agents" — so the agent does the writing?**
+The other way round. You are the author; the agent is the reader. That is the whole difficulty of the genre: you are writing for a reader who has already read everything, so explanation is waste and precision is the entire job.
+
+**Can't I just ask the agent to write it for me?**
+You can, and it will produce something verbose. Left alone the model explains what it already knows, and it will not apply the no-op test or reach for a leading word on its own. Use the reference on the draft — a review pass is where most of its value lands.
+
+**I asked an agent to trim a document and it cut the functionality.**
+Agents told to "streamline" optimise for length, because length is the thing they can see. The no-op test is behavioural, not aesthetic: delete the line and ask whether the agent's behaviour changed. When a sentence fails, delete the whole sentence rather than trim words from it — and settle a disagreement about it by running the document, not by arguing.
+
+**How do I know when it's done?**
+When it works, and you can no longer find duplication, sediment or no-ops. There is no automated eval here; the check is a manual run plus the failure-mode vocabulary as a diagnostic. When a document misbehaves, that vocabulary is also the repair kit — name the failure mode first, then fix that.
+
+**Should this live in `CLAUDE.md` or somewhere else?**
+Ask which load you want to pay. `CLAUDE.md` loads into every session unconditionally; material behind a pointer costs only the pointer's own line until it fires. Anything that applies in one context out of ten is paying context load the nine other times.
+
+**Do I need to rewrite my documents for each new model?**
+Mostly no, and over-fitting to one model is its own trap. Updating for a new model is usually another no-op pass rather than a rewrite.
+
+**My skill only works on the exact task I built it from.**
+The common route — do the work once, then have the agent write it up as a skill — over-indexes on that one run, and the exemplars come out too specific. Keep the run as evidence, then abstract deliberately: strip what belonged to that repo and those files, and write for the class of task.
+
+**English isn't my first language. Do I lose the leading-word advantage?**
+No — finding the word that packs the most behaviour into the fewest tokens is work the reference does for you. It is one of the things it is for.
+
+## It's working if
+
+- The document gets shorter as it gets better, and you are surprised how little is left.
+- You can point at a leading word and watch it doing work in more than one place.
+- Nothing is stated twice, in any form. Duplication is the most reliable sign a document was never tested.
+- Reference that only one branch needs sits behind a pointer rather than in the main file.

+This is a reach-for-it-anytime standalone reference. It has no neighbour in the chain because it sits underneath the whole set rather than beside any one skill: every skill here was written against it, and the documents the other skills leave behind — a `CONTEXT.md` and its ADRs, a spec, a ticket — are exactly the text it governs once an agent has to read them.
