Best Claude use cases for agent setup & config

Start Claude Code with --advisor opus: Sonnet 5 codes, Haiku 5.5 subagents search, Opus is consulted only at 3 checkpoints.

1. Start Claude Code with: claude --model sonnet --advisor opus
2. Create three read-only Haiku 5.5 subagents: search (maps the repo), grep (finds call sites), docs (pulls the API reference).
3. Add one rule to CLAUDE.md: consult the advisor before locking a plan, after the same error hits twice, and before calling a task done.

The i-have-adhd skill makes coding assistants put the action first, number the steps and drop filler.

1. Paste into your CLI: “Install the i-have-adhd skill/plugin from https://github.com/ayghri/i-have-adhd, refer to the repo’s AGENTS.md for instructions.”
2. Expect: action first, numbered steps, no “Hope this helps!”.

GPT-6.1 Sol plans and reviews only; local Qwen workers on one RTX 3090 do every write. Slower but cheaper.

1. Let the orchestrator read, plan, delegate and review; refuse every write or shell call it tries.
2. Only workers touch files (local Qwen 3.8 27B in the source).
3. Measure cost and time per task (77% cheaper; 43 min vs under 7).

Nimrod reads each agent’s local session files into one SQLite log, injects a project brief at session start and answers queries over MCP.

1. Read each agent’s own session store (JSONL or SQLite on disk) without writing to it.
2. Extract what was asked, files touched, commands run and how it ended into one local SQLite database; no model writes to the log.
3. Inject a short project brief at the start of each session.

A 20-line Stop hook runs the test suite whenever Claude tries to finish and sends it back on failure.

1. Add a Stop hook that runs your tests when Claude tries to finish.
2. If tests fail, return the failure so Claude goes back to work.
3. Related: one rulebook that overrides everything, “lanes” for job size, and permissions.ask for git push.

After agents burned $200 of credits chatting, an auditor agent lists every agent and what it costs.

1. Give one agent the auditor job. In Claude Code the author pastes a prompt that starts “You’re my agent auditor. List every…”.
2. List every running agent, what it does and what it costs.
3. Flag agents that talk to each other without producing anything; the author lost $200 of credits this way.

Instead of one PROGRESS.md, ordered runlevel-style state files plus fork/wait subagents survived two 230k-token compactions.

1. Don’t trust the auto-summary after compaction; keep state on disk.
2. Avoid a single TODO.md/PROGRESS.md scratchpad; it gets stale or overwritten.
3. Use ordered, lexically numbered state files per step, like SysV /etc/init.d runlevels, that the agent re-reads to resume.

No worktrees: sessions agree on a split, stage only their own hunks by id, and stop if the hunk count changes.

1. Have sessions agree on a split by message and list the files each will touch.
2. For shared files, stage only your own changes hunk by hunk, matched by an id in the changed lines.
3. Use a small command that lists hunks and stages matching ones; if the hunk count changed between listing and staging, stage nothing and stop.

A non-typing builder: Kiro writes, Claude reviews, she decides. Both agents over-hardened a throwaway; a rigor budget fixed it.

1. Split roles: Kiro builds, Claude reviews against your rules, you validate and decide.
2. Tag throwaway code explicitly, and tell both agents what the tag means; they won’t watch it for you.
3. Compliance gate: ~10 minutes before implementing, check you’re allowed to build it the way you intend.

A YAML spec the planner must emit and implementers echo back cut wrong-problem retries from 31% to 7% in a Claude Code loop.

1. Treat the handoff as an interface, not a message: the planner must emit one fenced block that validates against a schema (task_id, goal, target files, acceptance criteria…).
2. Have the implementer echo the spec back in its own words before touching code; reject mismatches.
3. Reuse the same spec as the input for the verifier agent.

Many cheap models speak the Anthropic API, so a small tool (cameo) lets Opus delegate to them as subagents.

1. Note that many cheap models expose Anthropic-compatible endpoints.
2. Wrap each one so Claude Code can launch it as a subagent (the author’s cameo, built by Opus in one shot from a short prompt).
3. Keep your main session on Claude; delegate grunt work to the cheaper subagents.

A shop agent’s CLAUDE.md, split from 548KB to under a 45KB cap, regrew in 18 days; per-section limits and moving rules to skills held.

1. Split a bloated CLAUDE.md into a short core plus skills.
2. A total-size cap alone invites the wrong deletions; add structure tests (body size, line count, longest line, footer budget).
3. When a section grows, move it into the skill that uses it (approval rules, fetch commands) instead of trimming elsewhere.

DeepSeek V4.1 Flash passed every run of his two-task test at about two cents a task (self-reported, "a field report and not a ranking").

1. Point OpenCode at OpenRouter (gateway optional): The author routes everything through LiteLLM with names like cloud-coder, fallbacks and per-app budgets.
2. Run your own two-task bake-off: One easy and one hard task with hidden tests; two runs per model; grade pass/fail, time and cost.
3. Pick the cheapest model that passes: For him: DeepSeek V4.1 Flash as default.
