+# Anthropic CLI (`ant`)
+
+The `ant` CLI exposes every Claude API resource as a shell subcommand. Compared to `curl`: request bodies are built from typed flags or piped YAML instead of hand-written JSON, `@path` inlines file contents into any string field, `--transform` extracts fields with a GJSON path (no `jq`), list endpoints auto-paginate (cap total results with `--max-items N`; `--limit` only sets the server page size), and the `beta:` prefix auto-sets the right `anthropic-beta` header.
+
+## When to use the CLI vs the SDK
+
+**CLI for the control plane, SDK for the data plane.** Agents and environments are relatively static resources you define, configure, and debug with `ant` — check the YAML into your repo, apply from CI, inspect from a terminal. Sessions are dynamic and driven by your application through the SDK — create per task, stream events, react to tool calls, integrate into your product. Both hit the same API; the split is about where the call lives, not what's possible.
+
+| | Control plane → `ant` | Data plane → SDK |
+|---|---|---|
+| Resources | agents, environments, skills, vaults, files | sessions, events |
+| Cadence | Once per deploy / ad-hoc | Every task / every turn |
+| Lives in | `*.yaml` in your repo + CI + terminal | Application code |
+| Typical calls | `create < agent.yaml`, `update --version N`, `list`, `retrieve`, `archive`, `--debug` | `sessions.create()`, `events.stream()`, `events.send()` |
+
+## Install and auth
+
+```sh
+# macOS
+brew install anthropics/tap/ant
+xattr -d com.apple.quarantine "$(brew --prefix)/bin/ant"
+
+# Linux / WSL — pick the release from github.com/anthropics/anthropic-cli/releases
+curl -fsSL "https://github.com/anthropics/anthropic-cli/releases/download/v${VERSION}/ant_${VERSION}_$(uname -s | tr A-Z a-z)_$(uname -m | sed -e s/x86_64/amd64/ -e s/aarch64/arm64/).tar.gz" \
+ | sudo tar -xz -C /usr/local/bin ant
+
+# Or from source (Go 1.22+)
+go install github.com/anthropics/anthropic-cli/cmd/ant@latest
+```
+
+Auth is `ANTHROPIC_API_KEY` from the environment. Override the host with `ANTHROPIC_BASE_URL` or `--base-url`.
+
+## Command structure
+
+```
+ant [:] [flags]
+```
+
+Beta resources (agents, sessions, environments, deployments, skills, vaults, memory stores) live under `beta:` — the CLI auto-sends the right `anthropic-beta` header, so don't pass it yourself unless overriding with `--beta `.
+
+```sh
+ant models list
+ant messages create --model {{OPUS_ID}} --max-tokens 1024 --message '{role: user, content: "Hello"}'
+ant beta:agents retrieve --agent-id agent_01...
+ant beta:sessions:events list --session-id session_01...
+```
+
+`ant --help` lists resources; append `--help` to any subcommand for its flags.
+
+## Global flags
+
+| Flag | Purpose |
+| --- | --- |
+| `--format` | `auto` (default: pretty if TTY, compact if piped), `json`, `jsonl`, `yaml`, `pretty`, `raw`, `explore` (interactive TUI) |
+| `--transform` | GJSON path applied to the response (per-item on list endpoints). Not applied when `--format raw`. |
+| `-r`, `--raw-output` | If the transformed result is a string, print it without quotes (jq semantics). Pair with `--transform` for scalar capture. |
+| `--max-items` | Cap total results returned from auto-paginating list endpoints (distinct from `--limit`, which is the server page size). |
+| `--format-error` / `--transform-error` | Same as `--format`/`--transform`, applied to error responses. `-r` does not apply to the error path — use `--format-error yaml` for unquoted error scalars. |
+| `--base-url` | Override API host |
+| `--debug` | Print full HTTP request + response to stderr (API key redacted) |
+
+## Output — `--transform` + `--format`
+
+`--transform` takes a [GJSON path](https://github.com/tidwall/gjson/blob/master/SYNTAX.md). On list endpoints it runs **per item**, not on the envelope.
+
+```sh
+ant beta:agents list --transform '{id,name,model}' --format jsonl
+```
+
+**Extract a scalar for shell use:** pair `--transform` with `-r` (`--raw-output` — prints strings unquoted, jq-style):
+
+```sh
+AGENT_ID=$(ant beta:agents create --name "My Agent" --model '{id: {{SONNET_ID}}}' \
+ --transform id -r)
+```
+
+## Input — flags, stdin, `@file`
+
+**Flags** — scalar fields map directly. Structured fields accept relaxed-YAML syntax (unquoted keys) or strict JSON. Repeatable flags build arrays (each `--tool`, `--event`, `--message` appends one element):
+
+```sh
+ant beta:agents create \
+ --name "Research Agent" \
+ --model '{id: {{OPUS_ID}}}' \
+ --tool '{type: agent_toolset_20260401}' \
+ --tool '{type: custom, name: search_docs, input_schema: {type: object, properties: {query: {type: string}}}}'
+```
+
+**Stdin** — pipe a full JSON or YAML body. Merged with flags; flags win on conflict (for array fields, any flag **replaces** the stdin array entirely — it does not append). Quote the heredoc delimiter (`<<'YAML'`) to disable shell expansion inside the body:
+
+```sh
+ant beta:agents create <<'YAML'
+name: Research Agent
+model: {{OPUS_ID}}
+system: |
+ You are a research assistant. Cite sources for every claim.
+tools:
+ - type: agent_toolset_20260401

+
+**`@file` references** — inline a file's contents into any string-valued field. Inside structured flag values, quote the path. Binary files are auto-base64'd; force with `@file://` (text) or `@data://` (base64). Escape a literal leading `@` as `\@`.
+
+```sh
+ant beta:agents create --name "Researcher" --model '{id: {{SONNET_ID}}}' --system @./prompts/researcher.txt
+
+ant messages create --model {{OPUS_ID}} --max-tokens 1024 \

+ {type: document, source: {type: base64, media_type: application/pdf, data: "@./scan.pdf"}},
+ {type: text, text: "Extract the text from this scanned document."}
+ ]}' \
+ --transform 'content.0.text' -r
+```
+
+Flags that natively take a file path (e.g. `--file` on `beta:files upload`) accept a bare path without `@`.
+
+## Version-controlled Managed Agents resources
+
+This is the recommended flow for defining agents and environments — check the YAML into your repo and sync via `create` (first time) / `update` (thereafter). See `shared/managed-agents-core.md` for the field reference.
+
+```yaml
+# summarizer.agent.yaml
+name: Summarizer
+model: {{SONNET_ID}}
+system: |
+ You are a helpful assistant that writes concise summaries.
+tools:
+ - type: agent_toolset_20260401
+```
+
+```sh
+# Create (once) — capture the ID
+AGENT_ID=$(ant beta:agents create < summarizer.agent.yaml --transform id -r)
+
+# Update (CI) — needs ID + current version (optimistic lock)
+ant beta:agents update --agent-id "$AGENT_ID" --version 1 < summarizer.agent.yaml
+```
+
+Same pattern for environments (`ant beta:environments create|update < env.yaml`), then start a session with both IDs:
+
+```sh
+ant beta:sessions create --agent "$AGENT_ID" --environment-id "$ENV_ID" --title "Task"
+ant beta:sessions:events send --session-id "$SID" \
+ --event '{type: user.message, content: [{type: text, text: "Summarize X"}]}'
+ant beta:sessions:events list --session-id "$SID" --transform 'content.0.text' -r
+ant beta:sessions:events stream --session-id "$SID" # live event stream
+```
+
+### Interactive session loop (stream-before-send)
+
+`ant beta:sessions:events stream` only delivers events emitted *after* the stream opens — so open it **before** sending the kickoff to avoid missing early events. Use process substitution to hold the stream on a file descriptor, send, then read:
+
+```sh
+exec {stream}< <(ant beta:sessions:events stream --session-id "$SID" \
+ --transform '{type,text:content.#(type=="text").text,err:error.message}' --format yaml)
+
+ant beta:sessions:events send --session-id "$SID" > /dev/null <<'YAML'
+events:
+ - type: user.message
+ content:
+ - type: text
+ text: Summarize the repo README
+YAML
+
+type=
+while IFS= read -r -u "$stream" line; do
+ case "$line" in
+ type:\ session.status_idle) break ;;
+ type:\ session.error)
+ IFS= read -r -u "$stream" next || next=
+ case "$next" in err:\ *) msg=${next#err: } ;; *) msg=unknown ;; esac
+ printf '\
+[Error: %s]\
+' "$msg"; break ;;
+ type:\ *) type=${line#type: } ;;
+ text:*)
+ [[ $type == agent.message ]] || continue
+ val=${line#text: }
+ case "$val" in '|-'|'|') ;; *) printf '%s' "$val" ;; esac ;;
+ \ \ *)
+ if [[ $type == agent.message ]]; then printf '%s\
+' "${line# }"; fi ;;
+ esac
+done
+exec {stream}<&-
+```
+
+This works for interactive exploration and demos. For application code that needs to react to `agent.tool_use` / `agent.custom_tool_use` events, reconnect after drops, or dedup against `events.list`, use the SDK — see `shared/managed-agents-client-patterns.md`.
+
+## Scripting patterns
+
+`--transform id -r` on a list endpoint emits one bare ID per line — compose with `xargs`, or use `--max-items N` to bound the result set without piping through `head`:
+
+```sh
+FIRST=$(ant beta:agents list --transform id -r --max-items 1)
+ant beta:agents:versions list --agent-id "$FIRST" --transform '{version,created_at}' --format jsonl
+```
+
+Error shaping mirrors the success path (note: `-r` does not apply to error output — use `--format-error yaml` for an unquoted scalar here):
+
+```sh
+ant beta:agents retrieve --agent-id bogus --transform-error error.message --format-error yaml 2>&1
+```
+
+Shell completion: `ant @completion {zsh|bash|fish|powershell}`.
+
+For the full, always-current reference (including per-endpoint flags), WebFetch the **Anthropic CLI** URL in `shared/live-sources.md`.

+## Client Configuration
+
+### Per-request overrides
+
+Use `with_options()` to override client settings for a single call without mutating the client:
+
+```python
+client.with_options(timeout=5.0, max_retries=5).messages.create(
+ model="{{OPUS_ID}}",
+ max_tokens=1024,
+ messages=[{"role": "user", "content": "Hello"}],
+)
+```
+
+### Timeouts
+
+Default request timeout is 10 minutes. Pass a float (seconds) or an `httpx.Timeout` for granular control. On timeout the SDK raises `anthropic.APITimeoutError` (and retries per `max_retries`).
+
+```python
+import httpx
+
+client = anthropic.Anthropic(timeout=20.0)
+client = anthropic.Anthropic(
+ timeout=httpx.Timeout(60.0, read=5.0, write=10.0, connect=2.0),
+)
+```
+
+### Retries
+
+The SDK auto-retries connection errors, 408, 409, 429, and ≥500 with exponential backoff (default 2 retries). Set `max_retries` on the client or via `with_options()`; `max_retries=0` disables.
+
+### Async performance (aiohttp backend)
+
+For high-concurrency async workloads, install `anthropic[aiohttp]` and pass `DefaultAioHttpClient` instead of the default httpx backend:
+
+```python
+from anthropic import AsyncAnthropic, DefaultAioHttpClient
+
+async with AsyncAnthropic(http_client=DefaultAioHttpClient()) as client:
+ ...
+```
+
+### Custom HTTP client (proxy, base URL)
+
+Use `DefaultHttpxClient` / `DefaultAsyncHttpxClient` — not raw `httpx.Client` — so the SDK's default timeouts and connection limits are preserved:
+
+```python
+from anthropic import Anthropic, DefaultHttpxClient
+
+client = Anthropic(
+ base_url="http://my.test.server.example.com:8083", # or ANTHROPIC_BASE_URL env var
+ http_client=DefaultHttpxClient(proxy="http://my.test.proxy.example.com"),
+)
+```

Each `POST /v1/agents/{id}` (update) creates a new immutable version (numeric timestamp, e.g. `1772585501101368014`). The agent's history is append-only — you can't edit a past version.

On native Windows the flag has no effect.

-${ADDITIONAL_CONTEXT_BLOCK}${PREVIOUS_AGENT_SUMMARY}
-IMPORTANT:
-- You have NO tools available — do not attempt to call any tool
-- This is a one-off response — there will be no follow-up turns
-- Respond with ONLY a JSON object on a single line, nothing else (no code fences, no prose)
-
-The JSON must have exactly these fields:
-{"status_category":"blocked|review_ready","status_detail":"...","title":"...","needs_action":"..."}
-
-Formatting: all fields except title accept markdown. Use `backticks` for file names, function names, and shell commands. Use [text](url) for PRs and documents. Keep title plain text.
-
-Frame fields in terms of user-visible behavior. Describe what the user will observe, what now works differently, or what broke or got fixed. Don't over-index on implementation details or specific lines of code unless the user is in the weeds with you — this summary is intentionally high-level. Good: "Login no longer loops on expired tokens", "Settings now sync across restarts".
-
-status_category — pick one based on who unblocks the session next:
-- blocked: Claude hit genuine ambiguity or a missing piece it can't route around — conflicting requirements, an unanswerable design question, context only the user has. NOT for awaiting review or normal handoffs: if Claude produced a deliverable and is waiting for eyes, use review_ready. Blocked indicates that a session is stuck, not waiting further direction or general review.
-- review_ready: Claude produced something the user should look at — a PR, a plan, a diff, a document, a pushed branch, or a conversational answer. This is the default end state; the user (not this classifier) decides when work is "done".
-
-status_detail — A 5-12 word blurb, scannable in an inbox row. Present tense, concrete, names the subject AND the cause in one breath — "Blocked on retry logic merge: three call sites conflict", "PR #1234 ready: tests green, auth code needs review". The reader should know both WHAT state the conversation is currently in, and WHY without opening the session. Present tense, concrete.
-
-title — a short (3-6 words) title shown to the user in a list of all of their sessions. This title should be specific and actionable for the user to distinguish between other streams of work. Name the feature or bug being worked on, not the activity. Ex: "Fix infinite login redirect on /code". Keep this stable — only change this from your previously generated title if the session's focus has shifted. Write as a noun phrase or imperative, no subject.

-needs_action — A 5-12 word blurb, scannable in an inbox row. Present tense, concrete, names the subject AND the cause in one breath — "Blocked on retry logic merge: three call sites conflict", "PR #1234 ready: tests green, auth code needs review".

ALSO OFFER PROACTIVELY: after you finish work that has a natural future follow-up, end your reply with a one-line offer to schedule a background agent to do it. Strong signals: a feature flag / gate / experiment / staged rollout was just shipped (offer a one-time agent in ~2 weeks to open a cleanup PR or evaluate results), a new alert/monitor was created (offer a recurring agent to triage it), a TODO/migration with a "remove once X" condition was left behind (offer a one-time agent to do the removal). Skip the offer for refactors, bug fixes, and anything that is done once it ships. Name a concrete action and cadence ("in 2 weeks", "every Monday") and only offer when the run just succeeded — do not pitch a schedule for something that has not happened yet.
