Write Inline Documentation and README for an Undocumented Python Module
“Write inline documentation and a README for a previously undocumented internal Python module”
Summary · Write docstrings for all functions, classes, and methods in an existing undocumented internal Python module, plus a README covering purpose, installation, usage, and examples.
AI handles the mechanical and structural parts of code documentation very well—generating docstrings, formatting a README, inferring parameter types—and dramatically cuts drafting time. It falls short of 'excellent' because internal modules carry context (architectural decisions, known quirks, business logic) that AI cannot infer from code alone, and factual errors in generated docs require a competent reviewer to catch before shipping.
Where AI helps most
Instant draft generation of all docstrings and README structure in a single pass, eliminating the per-function reading-and-writing loop that consumes most of an expert's time.

Worker comparison
six profiles| Worker | Time | Cost | What you actually get | Conf. |
|---|---|---|---|---|
|
01
Solo Individual
DIY on your own time, no contract, no schedule
|
3–6 hours | $0 (own time, no hire) | No hiring friction since they are doing it themselves. The main pain is comprehension: someone without Python experience will struggle to accurately describe function behavior, parameter types, return values, and edge cases. Documentation tends to be generic or misleading rather than genuinely useful. If the module is handed to other developers later, this output is likely to need a full rewrite. | medium |
|
02
Solo Expert
Hire a freelance specialist, day rate, scoped per job
|
1–2.5 hours | $100–300 (at $75–120/hr) | Output quality is high, but sourcing a credible freelance Python developer or technical writer takes real effort: vetting portfolios, granting codebase access, signing an NDA if the code is sensitive, and a briefing call all happen before work starts. On a fixed-price one-off, revision rounds are typically limited and scope can creep silently if the module turns out larger or more intricate than initially described. Wall-clock time from engagement to delivery is often several days even if hands-on effort is under two hours. | high |
|
03
Small Team
Coordinate 2 or 3 freelancers, handoffs and gaps
|
2–4 hours | $400–900 (blended rate across 2–3 contributors) | A developer writing drafts while a tech writer polishes them yields better output, but handoff friction adds time. Style reconciliation between contributors is a real cost. Getting the original code author to review for accuracy is ideal but their calendar availability often pushes wall-clock delivery into the following week. Quality is the best among human options, but the process has more coordination surface area to go wrong. | medium |
|
04
Agency
Account-managed, billable hours, formal scope and SOW
|
4–8 hours billed | $800–2,000 (including onboarding and minimum engagement floors) | Agencies frequently apply a half-day or full-day minimum billing floor regardless of actual effort. Onboarding to an internal codebase—understanding naming conventions, dependencies, architectural intent—is billable and non-trivial. If the module has structural problems, the agency may flag refactoring as a prerequisite, expanding scope unexpectedly. Revision rounds are typically capped in the contract, and disputes over scope are common when the module is larger than described in the initial brief. | medium |
|
05
Enterprise
RFP, procurement, multi-stakeholder approvals
|
1–3 weeks wall-clock; ~4–8 hours of actual work | $1,500–4,000 (fully loaded headcount cost) | Internally, this task goes through ticket creation, sprint planning, PR submission, style guide compliance review, and often multiple stakeholder approvals before it is considered done. Different teams frequently disagree on documentation format. The actual hands-on work is modest, but organizational overhead dominates elapsed time. Calendar-time from assignment to merged documentation routinely stretches to weeks in typical enterprise engineering orgs. | medium |
|
AI
AI (Claude / Agent)
AI plus competent human review
|
25–65 minutes (including human review) | $10–60 (API or subscription cost plus reviewer time) | AI can ingest the full module and produce a complete draft of all docstrings plus a structured README in minutes. The main failure modes are: hallucinating behavior that does not match actual code logic, missing undocumented side effects, inferring wrong parameter types from ambiguous naming, and lacking internal business context that explains why the module exists. A competent developer reviewing and correcting the draft is not optional—plan on 20–45 minutes of focused review. Performance degrades meaningfully on highly complex or poorly structured code. Works best when function naming is reasonably descriptive. | high |
