fix(ci): gate playground badges on a real compile - #501
Conversation
174 of 306 badges opened on a compilation error instead of a working example. Two causes, both from guessing instead of checking. 169 snippets had no @meta block, so they died on "@meta block is required". The gate for that was `looksComplete || trimmedCode.length > 30`, which effectively passes everything. The other 12 carried `@use github.com/acme/agent-skills/...`; prepareCodeForPlayground comments out imports the playground cannot fetch, but its regex needed the target to start with `@`, and a host-style target does not, so it stayed live and the playground tried to clone a repository that does not exist. Heuristics only approximate the real question, so ask it directly: every candidate now compiles through browser-compiler, the engine the playground runs, with the formatters a first-time visitor has enabled. Badge only when it passes. The --check gate from #472 is already in CI, so this holds itself now. Three things fall out of it: - remote and URL imports get commented out like registry ones already were - a fragment with no @meta gets one supplied for the encoded state, so the badge works without padding every example in the docs with four lines of boilerplate - when disabling imports leaves nothing of the example, the badge is dropped. That snippet does compile once it has a @meta, but it opens on an empty project, and a button promising a demo that shows nothing is worse than none Also moved the script off `ts-node --esm` to the swc-node runner every other script here uses, since it now imports workspace sources. Refs #500
Mechanical regeneration so the new invariant holds on first run. 109 badges that opened on an error are gone, the rest re-encode against the same prepared state the gate validated. Verified nothing but badge blocks moved: stripped every playground-link-start/end block from both sides and diffed all 33 touched files, zero differences. That also rules out the fence-splitting this regex has caused before. Refs #500

Clears six SonarCloud findings on the previous commit, and the first one turned out to be hiding a real gap. The two import regexes tripped S5843 at complexity 22 and 26. Rather than golfing them under the limit, the classification moved to one small regex that splits an import line plus three cheap tests on the target. That also removed the S6535 unnecessary escape. Widening it that way caught imports the old patterns silently let through, all of which the playground cannot fetch either: a nested scope (`@company/@org/base`), a caret range (`@company/skills/release@^2.0.0`), parameterized inheritance (`@stacks/react-app(projectName: "my-app")`), remote skill filters (`github.com/owner/repo/skills(includes: [...])`), and placeholder lines carrying a trailing comment. Those snippets used to keep a live import and get dropped by the compile gate, so this recovers badges instead of losing them: 197 to 198, still zero failures. Rest of the findings: S4123 wanted the map callback in Promise.all to be async so no plain false is mixed in with promises, S6582 an optional chain, and S3776 a smaller main, so file collection and reporting moved out into their own functions.

The wider classifier disables imports the old patterns left live, so those snippets now compile and get a badge back. 198 badges, all compiling, none opening on an empty project. Same content-safety check as before: stripped every badge block from both origin/main and the working tree, diffed all 38 touched files, zero differences. Refs #500
CodeRabbit caught a real hole in the @meta synthesis. In "Common Mistakes to Avoid" the section titled Missing @meta Block shows a Wrong example with no @meta and a Correct one with it. Supplying the header for the encoded state made the Wrong example compile, so the badge handed the reader a working playground for the exact thing the page had just told them not to do. My change caused that, the old heuristic never got that far. A badge on an anti-pattern is wrong either way: if the snippet compiles it contradicts the lesson, if it does not the button is broken. So a fence introduced by wrong / incorrect / bad / avoid / don't / never, or by a cross mark, gets no badge at all. Preferred a rule over a skip marker on that one fence because the survey found seven such fences across three pages, and the next contributor writing a Wrong example should not have to remember the marker. 194 badges now, still zero failures and zero opening on an empty project. Refs #500
Regeneration after the anti-pattern rule. Seven fences across ai-migration-best-practices.md, fix-block-shapes.md, and security.md lose their badge; nothing else about them changes. Refs #500

Good catch on the The Missing @meta Block section shows Wrong without the header and Correct with it. Supplying the header for the encoded state made the Wrong example compile, so the badge handed the reader a working playground for the exact thing the page had just told them not to do. The old heuristic never reached that snippet, so my change is what introduced it. Went with a rule rather than a skip marker on that one fence. A badge on an anti-pattern is wrong either way: compiles and it contradicts the lesson, fails and the button is broken. So a fence introduced by wrong / incorrect / bad / avoid / don't / never, or by a cross mark, now gets no badge. Surveyed the docs first and found seven such fences across ai-migration-best-practices.md, fix-block-shapes.md and security.md, and I would rather not rely on the next person writing a Wrong example remembering the marker. Fixed in f1ba8ef with the regeneration in d1296c4. 194 badges, all compiling, none opening on an empty project, and zero left under a negative marker. |
Clears S7750. Same result, the scan stops at the first non-blank line from the end instead of building a filtered copy first. Badge output is unchanged, --check reports no drift. Refs #500
Commenting out every import the playground cannot fetch was costing real examples. An @inherit or @use line is often the whole point of a section, so disabling it left either a broken badge or a demonstration of nothing, and 69 of the 116 unbadged fences were unbadged for exactly that reason. ShareableState already carries a file list and the playground already resolves against it, so the imports stay live and travel with a placeholder file each. Registry and remote targets land at <target>.prs, the way the bundled registry is keyed; local targets keep their path. Only what no placeholder fits, a path traversing out of the virtual project, is still commented out. Parameterized imports get params derived from the call site, and that buys more than passing validation: the caller's own values interpolate into the output, so @inherit @stacks/react-app(projectName: "Checkout App", port: 8080) renders with "Checkout App" rather than a placeholder. Types come from the literal, quoted to string, true/false to boolean, numeric to number. Placeholder blocks are generic but not empty, because an example that overrides or extends a path needs that path to exist in the parent. Every stub opens with a line saying it was supplied here and is not documentation, same as the @meta header already does. Also stopped disabling targets the bundled registry already answers. @core/base, @core/quality and @core/security resolve untouched, and @core/security alone appeared in nine unbadged fences, so that was pure loss. 194 badges to 237, of which 69 now carry 120 placeholder files. Zero compile failures, zero opening on an empty project, and no encoded state contains a commented-out import any more. Refs #500
43 fences get a badge back now that their imports resolve instead of being commented out, and the ones that already had one re-encode with live imports. Content-safety check as before: stripped every badge block from both origin/main and the working tree, diffed all 38 touched files, zero differences. Refs #500
Clears S8786. The argument matcher had `\s*` on both sides of the colon and an unquoted alternative overlapping the quoted ones, so parts of the pattern competed for the same characters and it backtracked super-linearly. Separator is now explicit spaces and tabs, and the unquoted alternative excludes quotes, so nothing overlaps. Literals get trimmed since the wider class can pick up trailing space. Badge output is unchanged, --check reports no drift. Refs #500

Remove both playground badges from mixed example fences.

Avoid Deep Nesting fence, which also contains both. The ### 1. Keep Fragments Focused fence is mixed too, so moving the first badge there can still make the badge appear to endorse a negative example.

Prevent a stub from replacing example.prs.
stubFileName maps ./example and ./example.prs to example.prs. The stub then replaces the entry in files. The compiler validates that stub, and the encoded state opens it as the entry file. The badge can therefore open placeholder content instead of the documentation example.
🐛 Suggested fix
for (const [path, content] of supplied.stubs) {
- files.set(path, content);
+ if (!files.has(path)) {
+ files.set(path, content);
+ }
}The import then refers to the entry itself, so the compiler rejects the circular dependency and emits no badge.

Under "Missing @meta Block" the reader is told the snippet is wrong and then left with no way to see what wrong looks like. Opening the playground on "@meta block is required" is the whole lesson, so the badge is worth having as long as it says up front that it fails. A fence opts in with <!-- playground-link-expect-error -->, placed by hand. Only the author knows whether the compiler error is the mistake the section teaches, and it often is not: of the seven Wrong examples in the docs, three compile cleanly because the page is teaching a convention rather than a compile error, and one fails on an unrelated missing sibling file. Guessing from the prose would have produced four misleading badges. An opted-in fence is encoded verbatim. No @meta header, no placeholder imports, because the preparation would repair the very mistake: that example compiles the moment the header it is criticised for lacking is supplied. The gate inverts with it. A normal badge needs the snippet to compile, an error badge needs it to fail, and a snippet that compiles under the marker fails the run in every mode rather than quietly losing its badge. That turns the marker into a claim the compiler has to agree with: if a page calls something wrong and the compiler accepts it, someone hears about it. Wording and colour differ too. The same blue "Try in Playground" on a snippet that opens on an error reads as a broken button, so these say "See the error in Playground" in red. 240 badges: 237 run, 3 fail on purpose, zero where the button promises one thing and the compiler does the other. Refs #500
Adds the expect-error marker to the three Wrong examples whose compiler error is the mistake the section teaches: Missing @meta Block gives PS001, Loose Multi-line Strings in Objects and Forgetting Commas in Arrays give PS2000 parse errors pointing at the exact spot. The other four Wrong examples stay unbadged. Three of them compile cleanly and one fails on a missing sibling, so an error badge would have shown the reader something other than the lesson. Refs #500
Clears S3358 and S8786. The candidate preparation was a nested ternary, now a named function, which also gives the "encoded verbatim" reasoning somewhere proper to live. The argument matcher still backtracked: its unquoted alternative could start on whitespace, so it competed with the `[ \t]*` in front of it for the same spaces and the engine had to try every split. Excluding whitespace from that first character makes every part of the pattern match a disjoint set. Badge output is unchanged, --check reports no drift. Refs #500
Third attempt at S8786, this time without guessing at the analyser. Expressing `name: value` pairs as one pattern needs character classes on both sides of the separator that overlap on whitespace, so the engine has to try every way of splitting a run of spaces. Narrowing the classes twice did not settle it. Replaced with a small scan: split on commas outside quotes, then take the text either side of the first colon. Linear by construction, nothing left for the analyser to object to, and it reads closer to what the code means. The only pattern left is an anchored check on the parameter name. Badge output is unchanged, --check reports no drift. Refs #500
CodeRabbit caught two badges in multi-file.md sitting on fences that hold a "# ✅ Good" half and a "# ❌ Bad" half in one block. One badge cannot speak for both, and supplying the placeholder files made it worse than before: the Bad imports now resolve, so the badge actively demonstrated that `@use ./fragments/stuff` works fine right under the line calling it Bad. precedesNegativeExample only reads the prose in front of the fence, so it could not see this. Now the body is checked too, restricted to comment lines so a restriction like `- "Never log secrets"` is not mistaken for one. Six fences carry such a marker, three of which had a badge. Second finding from the same review: a `@use ./example` import would produce a placeholder named example.prs, which is the entry file name, and the placeholder would overwrite the example itself. No page does that today, so the badge would have been silently wrong the day someone wrote it. That name now falls into the same branch as a path traversing out of the project and stays disabled. 237 badges, 234 that run and 3 that fail on purpose, none where the button and the compiler disagree and none whose entry got overwritten. Refs #500
Picks up the pages the Deno work added on main and drops the three badges from fences that teach good and bad in the same block. Refs #500

Both valid, thanks. The mixed fences are the worse of the two and it is my change that made them worse. Before, the Bad imports in those blocks were commented out; once I started supplying placeholder files they resolve, so the badge was actively showing that The f1ba8ef and 2997a76 for the code, regeneration in 3b5140c. Also merged main since #488 landed while this was in flight, so the badges now cover the pages the Deno work added. 237 badges: 234 run, 3 fail on purpose under the new expect-error marker. Zero where the button promises one thing and the compiler does another, zero whose entry file got overwritten. |

CodeRabbit caught a truncation I had looked straight at and not recognised. The import line matcher took the target with \S+, which stops at the first space, so `@use ./phases/triage(severity: "critical")` yielded `./phases/triage(severity:` and the placeholder landed under that name instead of the one the compiler resolves. The import then failed and the gate dropped the badge. My very first survey printed `local: ./phases/triage(severity:` in the target list. I read it as display truncation. 21 import lines across 6 pages were affected: the parameterized inheritance examples in inheritance.md, language.md and security.md, the skill phases in skill-composition.md, the payment policy in real-life-checkout-service.md, and the remote skill filters in language.md. Taking the rest of the line and scanning for the target rather than widening the pattern to `(\S+\(.*\)|\S+)`: a greedy `.*` would swallow a trailing comment that happens to contain a closing paren, and this file has already collected two backtracking findings. Whitespace ends the target only outside parentheses, which also leaves `as alias` and trailing comments where they belong. 252 badges now, up from 244, 77 of them carrying placeholder files. Still zero where the button and the compiler disagree. Refs #500
Eight fences get a badge back now that their parameterized imports resolve under the right placeholder name. Refs #500

Good catch, and an embarrassing one: my very first survey printed Real scope is 21 import lines across 6 pages, all the parameterized ones: inheritance.md, language.md, security.md, skill-composition.md, real-life-checkout-service.md, plus the remote skill filters in language.md. Each produced a placeholder under a name the compiler never asks for, so the import failed and the gate dropped the badge. Went with a scan over the rest of the line rather than widening the pattern to 8173e2b for the fix, 4b2bafa for the regeneration. 252 badges now, up from 244, 77 carrying placeholder files, still zero where the button and the compiler disagree.

Clears S8786 on the widened import matcher. Taking the rest of the line with `(.*)` let it compete with the `[ \t]+` separator in front of it for the same spaces, so the engine had to try every split. Forcing the first captured character to be non-space removes the overlap. Badge output is unchanged, --check reports no drift. Refs #500

Description
174 of 306 "Try in Playground" badges opened on a compilation error instead of a
working example. Two causes, both from guessing rather than checking.
169 snippets had no
@metablock and died on@meta block is required. The gatemeant to catch that was
looksComplete || trimmedCode.length > 30, which passeseffectively everything. The other 12 carried
@use github.com/acme/agent-skills/...:prepareCodeForPlaygroundcomments outimports the playground cannot fetch, but its regex needed the target to start
with
@, and a host-style target does not, so it stayed live in the encodedstate and the playground tried to clone a repository that does not exist.
A static heuristic can only approximate "will the playground run this", so this
asks the question directly. Every candidate snippet is compiled through
@promptscript/browser-compiler, the engine the playground itself runs, with theformatters a first-time visitor has enabled. A badge is emitted only when that
compile succeeds. The
--checkdrift gate from #472 is already wired into CI, sothe invariant now holds itself.
Three behaviours fall out of that:
@metagets one supplied for the encoded state, so thebadge works without padding every example in the docs with four lines of
boilerplate that would distract from what the example teaches
dropped. Such a snippet does compile once it has a
@meta, but it opens on anempty project, and a button that promises a demonstration and delivers nothing
is worse than no button
Result: 306 badges down to 197, and all 197 compile. Also moved the script off
ts-node --esmonto the swc-node runner every other script here uses, since itnow imports workspace sources.
