…d edit The tools table is regenerated when a sync is applied; the skills table was not, so every skill added in the monorepo failed `host/readme.test.ts` here until someone wrote its row by hand. It has happened twice — `browser-evidence` (currents-dev/currents#3779) is the second — and each time it reds the sync check on the monorepo PR that adds the skill, for a reason in this repository. `sync-readme-tools.mjs` now writes both tables. The skills rows come from `loadSkills()`, which the build and the tests already read, rather than from a regex over source: it resolves the name off the directory and refuses a skill whose frontmatter disagrees, so a generated link cannot point at a directory that is not there. The row text is the description's first sentence, the rule the tools table already applies. A skill's description carries the phrases that make an agent reach for it after that sentence, which is guidance for a model rather than a table of contents. This rewrites the existing `collect-evidence` row, which had been shortened by hand. `--check` covers both tables and names the one that drifted.

…nder Three cases the tables would render wrong, none of which any current description or skill reaches — so no row changes. A `|` in a description closes its cell early and adds a column. Nothing catches it: `host/readme.test.ts` reads names out of the first cell and never looks at the shape of the row. Cells are escaped before the widths are measured. `firstSentence` broke on every period followed by a space, so a description reading "Use e.g. the runId" became the row "Use e.g.", and `!` or `?` ended no sentence at all. A break is now punctuation, space, then a capital — which keeps "git branch, etc. Requires projectId" splitting where it should, and leaves an abbreviation or a decimal alone, because those continue in lower case or in a digit. A skill named `visual#diff` rendered a link to `skills/visual`, the `#` being a fragment. Rejected at load rather than encoded at use: `encodeURIComponent` leaves `(` and `)`, which close a markdown link destination, and the name also goes into a `skill://` URI. The class is the one `host/readme.test.ts` already reads a name back with, so a name outside it would be missing from the table it was just written to.

changed the title
…ashes Nothing ran `--check`. `npm run verify`, CI and the sync all regenerate or ignore the tables rather than failing on a stale one, and `host/readme.test.ts` compares names, not the description beside them — so editing a frontmatter description, or editing a generated row by hand, left a README that disagreed with its source and passed everything. `verify` now runs the check, which is where a developer meets it and where the sync meets it after applying the script. The cell escape put a backslash before `|` without escaping the backslashes already there, so a description reading `a \| b` became `a \\| b` — a literal backslash and then a live delimiter, which is the corruption the escape exists to prevent. Backslashes are escaped first. No description in either catalog carries one today, so no row changes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…urce The regex captures what sits between the quotes, so every escape in it is still two characters, and only the quotes were being decoded. A description declaring `C:\Users` was carried as a backslash pair, which the markdown escape added last commit then doubled again — the README would have shown two backslashes where the tool declares one. Before that escape the pair rendered as one backslash by accident, two mistakes cancelling; now the literal is decoded first and escaped once. One pass rather than chained replaces, so a decoded backslash is not read again as the start of the next escape. Decoding also makes `\n` a real newline, which would end a table row wherever it fell, so a cell's whitespace runs collapse to a single space. No description in either catalog contains a backslash, so no row changes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

User description
What this fixes
The README has two generated-looking tables, and only one of them is generated.
sync-readme-tools.mjsrewrites the tools table and a sync runs it, so a tool added in the monorepo arrives with its row. The skills table has no generator, so a skill added in the monorepo arrives without one — andhost/readme.test.tsasserts the table matchesgetSkills()in both directions, so it fails until somebody writes the row here by hand.That has now happened twice.
browser-evidence(currents-dev/currents#3779) is the second, and #192 was the hand-written fix for it. Each time it redsbuilds and passes in currents-mcpon the monorepo PR that adds the skill, for a reason that lives in this repository and cannot be fixed from there.What it does
sync-readme-tools.mjswrites both tables.--checkcovers both and names whichever drifted.The skills rows come from
loadSkills()— the same function the build and the tests read — rather than from a regex over source. That matters more than reuse: it resolves a skill's name from its directory and refuses one whose frontmatter disagrees, so a generated[name](skills/name)link cannot point at a directory that is not there.host/readme.test.tsreads the name back out of that link, so the two agree by construction.The row text is the description's first sentence, which is the rule the tools table already applies. A skill's description continues past that sentence into the phrases that make an agent reach for it ("Use when asked to ..."), which is guidance for a model, not a table of contents.
Both table splices are now anchored to the start of a line, so a description that happens to contain
| Toolcannot be mistaken for the table header.What changes in the README
Both existing rows, which had been written by hand, become the first sentence of each skill's own description — and they sort by directory name, which is the order
loadSkills()returns:Longer, and no longer able to drift from the skill it describes. If a row reads too long, the place to shorten it is the SKILL.md frontmatter, where the agent reads it too.
Verified
npm run verifypasses on the rebase: format, types, build, 768 tests.browser-evidence: dropping the directory in as a sync would,--checkfailed naming the skills table,npm run sync-readmewrote the row, andreadme.test.tspassed — the failure this removes, reproduced and then gone.awkdisagrees only because the em dash is three bytes.Relationship to #192
Rebased onto it now that it has merged. Its
registerPromptfix and itsskills/browser-evidence/directory both stand; what this replaces is the hand-written README row it also carried, which is now generated. The conflict between the two was the skills table itself, resolved by taking main's README and runningnpm run sync-readmeover it.Had this landed first, #192 would have needed the directory and the mock and no README edit at all.
Not in scope: the README sentence "The server publishes every skill as an MCP resource" that currents-dev/currents#3780 makes incomplete — prompts belong beside it. That sentence describes code this copy has not received yet, so it belongs on the sync that brings
