docs agent failed: lost type info on generic parameters

Not specified by the original author.

TL;DR

Extract generics from the type declarations, not the runtime code. The agent parsed the emitted JavaScript where type parameters do not exist, so every generic rendered as a non-generic. Fix: run extraction against the TypeScript source or declaration files with the type checker, and render each type parameter with its name, constraint, and default.

The error

docs agent failed: lost type info on generic parameters

Steps

1. Pick a generic the docs render wrong, e.g. a class declared as Container of [T], and check what the docs page shows. Expected: the docs show the type with no type parameter listed.

2. Check what the extractor parses: if it reads compiled .js output or a plain JS AST, generics were erased before extraction began. Expected: you confirm the extractor input has no type information to begin with.

3. Point the extractor at the TypeScript source (or the generated .d.ts files) and use the TypeScript compiler API type checker to read type parameters, constraints, and defaults. Expected: the extractor now sees names like [T], constraints like extends [Base], and defaults.

4. Render each generic with its parameter list: name, constraint, and default, plus the type arguments at each use site. Expected: the Container page documents [T] with its constraint and default.

5. Re-run generation and spot-check generic functions, classes, and interfaces. Expected: no generic renders as a bare non-generic type.

Use this when

• reference docs show generic types without their type parameters
• constraints and defaults on type parameters are missing from the docs
• the pipeline extracts from compiled JS instead of TS source

Not for this skill when

• the language has no generics (the type info was never there)
• generics parse fine but overloads are wrong (a different extraction bug)
• you need runtime type reflection rather than static docs

Variant phrasings

• doc generator strips type parameters from generics
• reference docs missing generic constraints
• extractor ignores type arguments on generic classes
• typedoc-style output lost generics info

Why it happens

TypeScript erases generics at compile time, so any extractor reading JavaScript output or a JS-only AST sees a world where generics never existed. Only the type checker, working from source or declaration files, knows the type parameters.

Edge cases

• Declaration files out of sync with source: regenerate .d.ts from the current source before extracting.
• Generic defaults that reference other type parameters: render the default expression verbatim rather than trying to resolve it.
• Higher-kinded or conditional types: show the constraint text as written; do not attempt to simplify it.

TL;DR

Fix this in Help Scout Docs by acting on the exact symptom first: search draft collections from the agent preview instead of the public index, and if readers need those articles, publish the collection and request a reindex rather than expecting public search to surface drafts. Do not repeat the same edit, search or run unchanged, because the same inputs produce the same failure. Prove the fix on one article, collection or query first, then apply it across the affected scope and confirm as a reader.

Help Scout Docs search ignores articles inside draft collections

Use this when

• Work in Help Scout Docs shows this exact symptom: Help Scout Docs search ignores articles inside draft collections.
• The same symptom repeats after a retry with unchanged inputs.
• Readers or support agents are blocked until this item is corrected.

Not for this skill when

• The help center platform itself is down or returning outage notices. Resolve that first, then return here if this symptom remains.
• The content is correct and you only want a style or tone rewrite. That is an editorial pass, not this fix.

Steps

1. Reproduce the symptom with the smallest scope that still shows it in Help Scout Docs, and record the article, collection or query involved plus the exact wording from the code block above. Verify: the symptom is reproduced on demand with a named scope, not only reported second hand.
2. Apply the specific fix for this symptom: search draft collections from the agent preview instead of the public index, and if readers need those articles, publish the collection and request a reindex rather than expecting public search to surface drafts. Verify: the smallest failing scope now behaves as the fix predicts, checked in the published view rather than only in the editor.
3. Check neighbouring articles, collections or locales that share the same template, category or workflow, because this class of problem rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Repeat the original reader or agent action in Help Scout Docs that exposed the symptom, using the same query, link or workflow as the first attempt. Verify: the action completes and the original symptom does not appear.
5. Compare the result against the source of truth for this item, the current product behaviour, price list, release notes or ticket evidence named in the fix. Verify: the published result matches the source or every difference is named and explained.
6. Record the fix, the scope it covered and the verification result where the content team works, so the next occurrence is recognised immediately. Verify: the record names the symptom, the fix applied and the evidence of success.

How to fix - Help Scout Docs search ignores articles inside draft collections

The how to phrasing for the same problem in Help Scout Docs. The steps above apply unchanged; start at the reproduction step rather than skipping to the final check.

Help Scout Docs troubleshooting for this symptom

The symptom first phrasing used when the full message is hidden. Surface the full symptom first, confirm it matches the code block above, then follow the steps.

Why it happens

Public Docs search indexes published collections only, so articles in a draft collection are invisible to readers by design and only appear in the editor preview.

Edge cases

• The symptom appears in one locale, collection or audience view only. Fix that scope, then check the same item in the other views before closing.
• A cached or indexed copy keeps showing the old state after the fix. Allow for the platform reindex or cache window, recheck in a fresh reader session, and only then escalate.
• Two items have near identical titles. Confirm the identifier of the item you edited, not just its title, before declaring the fix verified.

Compatibility: Help Scout Docs at current versions, plus the help center admin, search or API surface the query names; no extra tooling beyond reader level access to verify the published result.

TL;DR

Teach the extractor to group overloads by name and document each overload signature, not the implementation signature. Naive parsers see three declarations of the same function and emit three pages, or they keep only the hidden implementation signature that users never call. Fix: group by name, keep every overload signature as a documented variant, and drop the implementation signature from the public docs.

The error

docs agent failed parsing overloaded function signatures

Steps

1. Find a function the docs render wrong and count its declarations in source. Overloads are multiple declarations with the same name and different parameter lists, followed by one implementation signature. Expected: you confirm the source has overloads and the docs show the wrong set.

2. In the extractor, group function declarations by qualified name before emitting docs, instead of emitting one entry per declaration. Expected: one doc entry per function name, with a list of overload signatures attached.

3. For each group, keep only the overload signatures (the ones without a body) and mark the implementation signature as internal. Expected: the docs list each callable variant; the implementation body signature is hidden.

4. Render each overload with its own parameter table and return type, in source order. Expected: readers see every way to call the function, matching the .d.ts or header file.

5. Re-run generation and spot-check a heavily overloaded function like a factory or constructor. Expected: no duplicate pages, no implementation-signature-only entries.

Use this when

• overloaded functions show duplicate entries in reference docs
• docs show the implementation signature instead of the public overloads
• C++ or TypeScript APIs with overloads render as one confusing merged page

Not for this skill when

• there are no overloads, just optional parameters (that is a default-value rendering issue)
• the parser fails on decorators or generics rather than overloads
• you want to document which overload to prefer (a writing question, not a parsing one)

Variant phrasings

• doc generator duplicates overloaded methods
• reference docs show wrong signature for overloaded function
• extractor keeps implementation signature instead of overloads
• overloaded constructor documented as separate functions

Why it happens

Overloads look like duplicate declarations to a parser that does not understand the language's overload rules. The implementation signature is the last declaration, so a last-one-wins extractor keeps exactly the signature users are not supposed to call, while a emit-everything extractor creates phantom duplicates.

Edge cases

• Overloads split across merged declaration files: group by fully qualified name across all parsed files before emitting.
• Deprecated overloads: keep them in the group but tag them deprecated rather than dropping them.
• Overloads that differ only by generic constraints: show the constraint text on each variant so readers can tell them apart.
