# Best Coding-Agent Documentation Tests to Run Before an SDK Release

## TL;DR

- **Final working-code test.** Pass when the package stays installed, an authenticated call succeeds, and the saved repository reproduces the expected output.
- **SDK method and version test.** Pass when the agent uses methods supported by the version installed in a current or legacy repository.
- **Documentation route and quickstart test.** Pass when links resolve to the right pages and the agent can find, run, and verify the example.
- **Safe authentication test.** Pass when sandbox setup works without unsafe shortcuts and paid or production actions still require human approval.
- **API error recovery test.** Pass when the agent corrects a bad request and completes the task.

The ranking follows each failure's effect on a real coding-agent task. After a focused documentation fix, [rerun the same task](https://www.withgauge.com/resources/how-to-test-coding-agents-integrate-your-api/).

## What a documentation test actually checks before a release

A pre-release documentation test follows a real coding agent through three separate checks. First, retrieval shows whether the agent finds the right instructions for the task and repository. Next, installation shows whether it selects and keeps the compatible SDK package. Finally, implementation shows whether the saved code runs and produces the expected result. Passing one check does not establish that the next one passed.

Retrieval deserves its own check because agents spend meaningful time in documentation. In a [sample of 500 coding-agent runs](https://www.withgauge.com/blog/what-makes-good-agent-documentation/), documentation accounted for 55% of page fetches. That figure describes the sample, not every agent run. A successful fetch can still lead to an incompatible install or code that fails when you run it.

Before an SDK release, give a real coding agent a task in a representative repository and set the pass criteria in advance. Inspect the pages it fetched, the package it installed, and the final repository it left behind. The ranked tests below use those observations to find release-blocking failures, rather than judging whether the documentation reads well.

## 1. Final working-code verification

A coding agent passes this test only when the code it leaves in the repository runs and produces the expected result. Give the agent a representative repository and a task that uses the release candidate SDK to read a fixed sandbox record. Before the run, define the expected record ID and the command that will check it. A convincing final message from the agent does not count as a pass.

Check three results separately. First, the SDK package must remain in the saved dependency manifest and lockfile. If the agent installs it and then removes or replaces it, check whether the quickstart names a version compatible with the repository's runtime and dependencies. Second, an authenticated sandbox request must succeed. If authentication fails, inspect whether the docs give the agent a usable sandbox setup path and explain any required human approval. An actual credential or API failure needs a product-side fix, not a documentation edit.

Finally, check out the agent's saved repository in a clean environment, follow its documented setup steps, and run the agreed verification command. The test passes only if the installed package remains in use, the authenticated call succeeds, and the saved code yields the expected record ID on a repeat run. If the agent's session worked but the clean checkout fails, fix the missing dependency, configuration step, or runnable example, then repeat the test. The [SDK quickstart verification checklist](https://www.withgauge.com/resources/agent-ready-sdk-quickstart-template-verification-checklist/) treats installation, authentication, and reproducible output as separate checks.

## 2. Stale or invented SDK method and version checks

A working documentation link cannot tell you whether an agent chose the right SDK method. The agent may read a real page, then write a method that no longer exists or install a package version that cannot run in your repository.

Run the same integration task in three representative repositories with current, legacy, and incompatible setups. Inspect the agent's trace and saved code to see which SDK version, runtime, dependencies, and authentication path it chose. The current repository should run with the documented example. The legacy repository should follow a supported version-specific path or identify the migration it needs, while the incompatible repository should report the constraint rather than produce code that appears complete.

When the agent mixes versions or invents a method, pin the installation version beside the example and name the exact supported runtime and dependencies. Check the repository's installed packages before changing the instructions. The [SDK compatibility matrix guide](https://www.withgauge.com/resources/how-to-build-agent-facing-sdk-compatibility-matrix/) covers how to document those routes, but the release test passes only when the agent selects the right route and its saved code runs.

## 3. Broken or guessed documentation URLs, including redirects and soft 404s

A broken documentation link can leave a coding agent guessing even after it appears to have fetched a page. In a representative repository, ask the agent to implement one SDK call, then give it an outdated URL and a plausible but nonexistent reference URL. Inspect the fetches and saved code. The test passes when the agent reaches the current documentation, uses its instructions, and completes the call. A successful fetch alone does not count as a pass.

When a page has one direct replacement, send a permanent redirect to that page. When no direct replacement exists, return a real 404 with pointers to likely canonical pages. Avoid a soft 404, such as a missing page that returns a success status or silently lands on a generic page, because the agent may treat that response as the reference it needed. After fixing the route, rerun the same task and check whether the agent uses the right page. Put required code and constraints near the top of long pages, since [agent extraction can omit instructions buried deeper in the page](https://www.withgauge.com/blog/what-makes-good-agent-documentation/).

## 4. Quickstart and setup-path completeness

In a [sample of 500 coding-agent runs](https://www.withgauge.com/resources/what-documentation-do-coding-agents-fetch/), setup, README, and quickstart pages accounted for 59% of documentation fetches. That makes the setup path a useful release test. An agent may find a quickstart and install the SDK but still lack the instructions needed to run an example and check its output.

Give a coding agent an existing repository and ask it to add one sandbox API call using only documentation it finds. Inspect the pages it fetches, the commands it runs, and the code it leaves behind. The test passes when the agent can follow a path from its first entry page through installation, configuration, a runnable example, and an explicit verification step. A successful package install alone does not count.

If the agent never finds the quickstart, link the current page from the entry point it fetched. If it installs the package but cannot run or check the example, add the missing code or verification instruction at that point in the path. The [SDK quickstart template and verification checklist](https://www.withgauge.com/resources/agent-ready-sdk-quickstart-template-verification-checklist/) can help you check for omissions without replacing the agent run.

## 5. llms.txt and map-file accuracy

An `llms.txt` file passes this test only when its links lead the agent to the right instructions for a working integration. The file can help an agent navigate your docs, but its presence alone does not show that the agent used it or that the code works. Gauge's [guide to writing llms.txt](https://www.withgauge.com/blog/how-to-write-a-good-llms-txt-file/) treats it as a short map to authoritative pages, not a replacement for those pages or a proven citation tactic.

Give a coding agent a representative repository and ask it to add an SDK integration. Inspect which map links it follows, whether those routes open the current setup and reference pages, and whether the saved code runs successfully. A valid link is only a retrieval pass. If the agent follows a stale route or reaches the wrong version, correct or remove the link, then rerun the same task. The test passes when the agent reaches the intended page and completes the integration.

## 6. Safe authentication and required human approval

Run the authentication test in a representative repository with only the sandbox access your policy permits. Ask a coding agent to configure the SDK and make a test request, then give it a task that requires human approval. Inspect the agent trace and final repository to classify the run using the [four authentication outcomes](https://www.withgauge.com/resources/how-to-remove-api-key-friction-for-coding-agents/).

- **Authorized autonomous setup.** The agent obtains permitted sandbox access, completes the test request, and keeps secrets out of source control. The sandbox instructions pass.
- **Expected approval pause.** The agent stops before an action that requires approval and tells you what it needs. Keep that pause for paid plans, destructive work, and production access.
- **Unexpected manual-only stall.** The agent stops during sandbox setup even though your policy permits a self-serve route. Document the authorized route and rerun the task.
- **Unsafe workaround.** The agent bypasses a required approval or exposes a key in saved code. Make the boundary explicit in the documentation and rerun the task to check that the agent stops safely.

Gauge can help you inspect the run and retest after a focused documentation change. The test diagnoses authentication friction. Gauge does not issue keys, change your authentication policy, or remove required approvals.

## 7. API error recovery

Send a deliberately invalid request during the same repository task you use for release testing. For example, give a required field an unsupported value, then inspect the agent's trace and saved code. The test passes when the agent uses the error to correct the request and completes the task with a verified API response. A retrieved error page or a successful package install does not count as recovery.

Check whether the error identifies the **field**, explains the **reason** for rejection, names the **accepted input**, states whether a **retry is safe**, gives an **exact fix**, and tells the agent how to **verify** the correction. If the agent guesses a new value or repeats a request that could create a duplicate action, make the error message more specific and [rerun the task](https://www.withgauge.com/resources/how-to-write-api-error-messages-for-coding-agents/).

If the agent follows a clear correction and the API still rejects a valid request, investigate the API behavior. Documentation and error-message edits can clarify correct behavior, but they cannot repair a broken endpoint.

## 8. Controlled rerun after a single documentation change

A controlled rerun checks whether a documentation fix changes what the agent actually does. Before the first run, choose a representative repository task and define what counts as done. For example, require the agent to leave the SDK installed and save code that makes an authenticated request and produces the expected output. A fetched page or successful install alone does not pass the test. [Gauge's testing guide](https://www.withgauge.com/resources/how-to-test-coding-agents-integrate-your-api/) recommends setting acceptance checks before the session and inspecting the final repository.

Run the task again after changing one documentation page. Keep the prompt, starting repository, agent, and model the same. Gauge can run these sandboxed sessions with real coding agents, then show which pages the agent searched and fetched, which packages it installed or removed, and what its commands and errors reveal. Inspect the full trace and final repository diff in both runs. If the agent still calls an outdated method, revise the version-specific instructions rather than treating the new page fetch as a pass.

The fix passes when the rerun meets the preset acceptance checks without introducing an unsafe workaround. Compare setup completion, unexpected human intervention, abandonment, and the final verified result across both runs. A required approval pause still counts as correct behavior when the task reaches a paid or production action. Gauge helps you diagnose and retest the documentation change. You still publish the docs and fix any broken API behavior yourself.

## Ranked test summary

Run each gate in the same representative repository with a [real coding agent](https://www.withgauge.com/resources/how-to-test-coding-agents-integrate-your-api/).

| Rank/Test | Failure caught | Observable pass criterion |
| --- | --- | --- |
| 1. Final working code | A finished-looking but broken integration | Package remains installed, authenticated call succeeds, and saved code reproduces the expected output. |
| 2. SDK methods and versions | Invented methods or incompatible dependencies | Agent uses supported methods and versions for the repository. |
| 3. Documentation URLs | Guessed links, bad redirects, or soft 404s | Agent reaches the intended page and uses its instructions. |
| 4. Quickstart path | Missing setup or verification steps | Agent installs, configures, runs, and verifies the example. |
| 5. Map-file routes | Stale links in `llms.txt` | Agent follows a current route into working code. |
| 6. Authentication | Unsafe workarounds or unexpected stalls | Agent completes authorized setup and pauses for required approval. |
| 7. API error recovery | An error the agent cannot correct | Agent fixes the request and completes the task. |
| 8. Controlled rerun | An unverified documentation fix | The same task passes after one targeted documentation change. |

## What a passing release actually looks like

A release passes when a coding agent finds the right documentation, keeps the correct SDK installed, and produces working code in the saved repository. Check each result separately. A successful page fetch cannot prove the package installed, and a successful install cannot prove the code makes an authenticated request.

After a focused documentation fix, [rerun the same task](https://www.withgauge.com/resources/how-to-test-coding-agents-integrate-your-api/) with the prompt, repository, agent, and model unchanged. Release only when the final repository passes the checks you set before the run.

## FAQs

### How do these tests differ from a compatibility matrix or quickstart checklist?

A [compatibility matrix](https://www.withgauge.com/resources/how-to-build-agent-facing-sdk-compatibility-matrix/) tells an agent which SDK version fits a repository, while a [quickstart checklist](https://www.withgauge.com/resources/agent-ready-sdk-quickstart-template-verification-checklist/) describes what setup and verification should include. These tests check what a coding agent actually does with that guidance in a representative repository. A passing document review cannot replace a working run.

### How often should you rerun the tests before a release?

Run the tests against the release candidate, then rerun any failed task after you make a focused documentation change. Keep the prompt, repository starting state, agent, and model fixed so you can compare the results. Repeat the relevant tasks if you change examples, version guidance, authentication instructions, or documentation routes before release.

### Does passing a retrieval test mean the implementation works?

No. An agent can fetch the right page and still install the wrong package version or save code that fails. Check retrieval, package installation, and the final repository separately, then run the saved code to confirm the expected result.

### How do human approvals fit into automated testing?

An automated test can check whether the agent pauses at the required approval point instead of bypassing it or getting stuck earlier. Paid, destructive, and production actions still need the required human approval, even when sandbox setup can proceed without it. [Gauge can help inspect the run](https://www.withgauge.com/resources/how-to-remove-api-key-friction-for-coding-agents/) and retest a documentation fix, but it does not grant approval or issue credentials.
