coding
### Turn an issue into a tested patch
Coding agents inspect repositories, edit files, run tests and return evidence. The useful deliverable is not plausible code; it is code proven to work.

coding
### Reproduce and repair real repository bugs
[SWE‑bench](https://isaiuseful.com/benchmarks.html.md#swe-bench) gives agents real GitHub issues and grades the resulting patches with tests. It is a practical model for bounded maintenance work.

coding
### Continue a project across agent sessions
A harness can preserve progress notes, git history and test state so a later context window resumes work instead of rebuilding an understanding from scratch.

coding · planning
### Plan a migration before touching the code
A specification workflow can inventory affected behavior, propose milestones and preserve non-goals before an agent starts a cross-cutting upgrade.

coding · verification
### Turn a reported bug into a regression test
Before accepting a fix, require a test that fails on the original behavior and passes after the patch. This is a practitioner verification rule, not a finding from the benchmark.
- [Practitioner method →](https://simonwillison.net/2025/Dec/18/code-proven-to-work/)
research
### Produce a cited research brief
Deep-research agents browse many sources, synthesize them and return citations. The researcher still checks provenance, coverage and whether each citation supports the claim.
- [Vendor capability report →](https://openai.com/index/introducing-deep-research/)
research
### Recover primary sources from weak clues
LLMs can act as secondary librarians: turn a remembered quote, chart or claim into candidate sources, while the human verifies the original material.
- [Practitioner examples →](https://simonwillison.net/tags/ai-assisted-search/)

### Compare revisions across a policy set
A proposed workflow can load named document versions into a bounded collection, ask for candidate differences and verify each one against the originals. The linked project supplies retrieval, not a purpose-built policy-diff guarantee.
- [Retrieval implementation →](https://github.com/Mintplex-Labs/anything-llm)
operations
### Run long, bounded workflows
Agent harnesses can retain task state, resume after context limits, run checks and stop on explicit completion conditions instead of relying on a single conversation.
- [Vendor implementation report →](https://www.anthropic.com/engineering/effective-harnesses-for-long-running-agents)
operations
### Operate software that has no API
Computer-use agents inspect screenshots, click and type in existing interfaces. Use narrow accounts, allowlisted sites and approval gates because visual automation is inherently brittle.
- [Vendor capability release →](https://www.anthropic.com/news/3-5-models-and-computer-use)

### Transcribe and search meetings
Whisper turns recordings into searchable transcripts. A follow-on model can extract decisions, owners and unanswered questions while the recording remains the canonical source.
- [Transcription implementation →](https://github.com/openai/whisper)

### Route, classify and draft from an inbox
A proposed workflow can route inbound messages, retrieve policy and prepare a response behind human approval. The linked guide documents routing and tool-use patterns, not this exact inbox deployment.
- [Vendor engineering pattern →](https://www.anthropic.com/engineering/building-effective-agents)
operations
### Run repeatable agent loops with state and review
A practitioner pattern combines scheduled runs, a state file, isolated worktrees, tools, a separate verifier and human review. It is a method proposal, not evidence of a measured reliability gain.

### Assist customer-support agents
A generative assistant can retrieve answers and suggest responses while the support worker remains responsible. A 5,179-worker field study measured higher issues resolved per hour.
- [Field study →](https://www.nber.org/papers/w31161)

small business · routing
### Qualify inbound requests before a person replies
A proposed routing workflow can classify requests by explicit criteria, retrieve the relevant offer and prepare follow-up questions without making commitments. The source documents the routing pattern, not a measured sales result.
- [Vendor engineering pattern →](https://www.anthropic.com/engineering/building-effective-agents)

- [Randomized-trial preprint →](https://arxiv.org/abs/2410.03017)
healthcare · draft only
### Prepare replies to patient messages
AI can prepare drafts for clinician review. A five-week single-group study found 20% adoption and no measured time savings; lower surveyed burden and exhaustion were observational, so the safe claim is feasibility—not proven efficiency.

Customer-reported implementation published by GitLab.
CI/CD troubleshooting · vendor case study
### Investigate a failed pipeline and prepare a proposed fix
Barclays uses GitLab Duo to explain failed job logs, identify a likely root cause and suggest a fix inside its developer workflow. GitLab's customer story describes one manager resolving a pipeline issue in seconds; that anecdote is not a controlled delivery-speed measure. Review the diagnosis and change before merge, and keep log and code access within approved controls.

chat-only mental model
### Ask, receive text, copy it somewhere
- No tools
- No direct inspection
- No memory of the work environment
- No deterministic completion check
agent mental model
### Observe, act, test, recover and report
- Reads relevant files and systems
- Uses terminals, APIs and applications
- Maintains task state and reusable skills
- Stops when tests or approval gates say it is done
**Mobile operating rule:** remote chat only exchanges messages; a remote assistant reads selected context and uses selected tools; a remote operator can change another machine or account. The phone-sized interface does not shrink the host-side permission boundary.
