Before & after
Same prompt, same agent — the only difference is the skill.
Prompt“Claude keeps inventing API methods that don’t exist in our stack.”
Beforegeneric AI agent
Hallucinated APIs are a common frustration. Here are some ways to reduce it: - Provide the actual documentation in your prompt - Share relevant code files so the model sees your real patterns - Be specific about library versions - Ask the model to only use APIs it can verify - Correct it when it invents something so it adjusts The core issue is that the model's training data may be outdated or it fills gaps with plausible-sounding but incorrect APIs. Grounding it in your actual code and current docs helps a lot. Which library or framework is it getting wrong?
Afterwith Context7
That's the #1 large-project failure mode, and it's structural: the model
is limited to its training data + whatever fits the context window, so
on a big or recently-updated stack it fills gaps with plausible-looking
APIs. Context7 removes the gap instead of correcting it after the fact.
WHAT IT CHANGES
• Live documentation lookup — Claude retrieves the CURRENT docs for
your exact library version on demand, instead of recalling a
possibly-outdated version from training.
• Smart codebase search — it pulls the real patterns and conventions
already in your repo, so it matches your code rather than inventing
a generic shape.
THE MECHANISM THAT MATTERS
Retrieval on demand, not preload. It doesn't try to stuff your whole
codebase into context (which fails past a certain size). It fetches the
exact doc page or code pattern when the task needs it — so a 500K-line
project stops being "too big to reason about."
BEFORE / AFTER, CONCRETELY
Without: "use client.users.findByEmail()" — plausible, doesn't exist,
you find out at runtime.
With: it looks up your actual data layer first, sees
user.repository.findOne({ email }), and writes that.
WHY IT'S A GLOBAL-INSTALL RECOMMENDATION
Experts put it on every project because the failure it fixes —
convention drift and invented APIs — is universal on large codebases,
not specific to one stack. It's one of three commonly recommended
always-on skills for exactly that reason.
Once it's installed, the correction loop you're doing now mostly
disappears — the model retrieves the real API instead of guessing and
waiting to be corrected.
Which library is it hallucinating most? That's the first one to confirm
it's resolving correctly.About this skill

Context7
Context7 fixes Claude's most common failure mode on large projects: hallucinating APIs, patterns, and conventions. It gives Claude live documentation lookup and smart codebase search so it can retrieve the exact docs and patterns it needs on demand, rather than being limited to its context window. One of three skills experts recommend installing globally on every project.
What you get
- Live docs lookup, smart codebase search, convention-aware code generation, on-demand pattern retrieval across massive projects.
Customize your output
- Index your documentation sources and define preferred pattern libraries and internal style guides for Claude to reference.
Example output
Claude retrieved the correct v3 pagination pattern from internal docs — no hallucinated parameters, output matches existing implementation exactly.
Best for
Developers on large codebases, teams with custom documentation and conventions, anyone hitting Claude's context window limits on big projects.

# Context7
Retrieves live, version-accurate documentation and searches the actual codebase for existing conventions before writing code, instead of relying on stale training data.
