Saves the main session's quota and context. Picks the model from ROUTING.md unless the user names one, and never routes back to the host's own model (except an Opus subagent under an Opus host, which keeps the main context clean). Use for mechanical, large work: scaffolding, boilerplate, repetitive edits across many files, test stubs, docstrings, format conversions, a fully specified function or module, or bulk reading of media and long documents. Also use when the user says /delegate, \"delegate this\", \"send this to Codex/Gemini/Claude\", or \"don't burn tokens on this\". The host always plans, specs and verifies; the delegate only types. Do NOT delegate debugging, architecture, cross-file refactors, security code, anything subtle, or work under ~40 lines." --- # Delegate **Host** = the agent running this skill (Claude Code or Codex CLI). **Delegate** = another model the user also pays for, reached through its own CLI. Each has its own quota. **Bulk typing happens in the delegate. Thinking happens in the host.** | Host | Delegate | | --- | --- | | Read the codebase, understand the flow | — | | Decide the design, pick the files | — | | Write a spec with every decision already made | — | | — | Type the code / read the media | | Run it, read the diff, verify | — | | Fix or re-delegate | — | **Verification is always the host's.** "Done" from a delegate is not evidence. Run the check, read the diff, and confirm it did what was asked *and nothing else*. **Your own rules.** If `${XDG_CONFIG_HOME:-~/.config}/delegate-router/LOCAL.md` exists, read it first. It is the user's file, outside this repo (CLI paths, effort limits, data gates, extra routes); **where it disagrees with this file or ROUTING.md, it wins.** ## 1. Judge: every time, before delegating Delegating costs the host tokens too: it writes the spec and reads the result. **Delegate when ALL of these hold:** 1. **Bulk:** roughly 40+ lines of output, the same edit across 3+ files, or a large media/document read. 2. **Decided:** no design judgement left. Every choice is in the spec. 3. **Verifiable:** a command proves it worked (a test, a run, a diff check). 4. **Contained:** one file, or files that needn't be reasoned about together. **Never delegate:** - Debugging. Root-causing needs the whole picture. - Architecture, interface design, or naming the rest of the codebase depends on. - Cross-file refactors whose edits must stay consistent. - Security, auth, money or trust-boundary code. A strong reviewer may *review* it; no delegate types it. - Anything under ~40 lines. **The spec would be longer than the code.** - Anything the user is actively following along with. **The honest test:** *if writing the spec takes longer than writing the code, write the code.* Say so in one line and move on. ## 2. Pick the model 1. **Check what's installed and new** (offline itself, under a second; with `BACKGROUND=1` it may start a detached online check, at most every 12 h): `python3 /scripts/model_watch.py status` It prints the delegate CLIs on this machine, and any new model release it found. If it reports something new, tell the user once in one line, then carry on with the current map. A line starting `delegate-router: ROUTE ... (applied)` replaces that ROUTING.md row's first candidate for this run; `(proposed)` lines are reported to the user, not acted on. 2. **The user named a model?** Use it. Done. 3. **Otherwise read [ROUTING.md](ROUTING.md)** (same folder) and take the row that matches the task. Walk its candidates in order and take the first one that is **installed**, is **not the host's own model**, and **runs on another subscription than the host** when the row has one (ROUTING.md, "How to read a row", has the plans and the two rows that skip this). One exception: under an Opus host, the `opus-implementer` subagent is allowed, because it keeps file reads and tool turns out of the main context. Don't route from memory. ## 2b. Scout before the spec (optional, needs Jev) Only when `JEV=1` in `~/.config/delegate-router/config.env`. Otherwise skip this step. **When:** the task's files aren't named yet, and about 5+ candidate files would otherwise be read just to find the ones that matter. **Data gate:** scouting sends file paths and contents to TypeSafe. Only public or low-sensitivity code. **Never** client work, secrets or config, credentials, personal data. ```bash cd && rg -l | uv run --quiet /scripts/jev.py scout "" --top 15 ``` 1. **Read only the top files** needed to design the spec, plus files the task names, and any `skipped:` or `(cut)` file that could matter. **A low score is not proof.** 2. **Put the confirmed file list in the spec**: "Read only these files: …; don't explore beyond them unless one imports something you need." 3. **Verification never uses Jev.** Read the full diff yourself. ## 3. Run it Write the spec to a temp file first (`packet.md`) and pass it in. **Never print a delegate's full output into the host's context**: read its short summary and the diff. ### Codex (`codex exec`): agent mode, edits real files ```bash codex exec -m -c model_reasoning_effort= \ --ignore-user-config --ignore-rules -c features.apps=false \ -s workspace-write -C -o /delegate-out.md \ "$(cat /packet.md)" < /dev/null ``` - **Always pass `-m` and the effort.** Codex's own default model may not be the one you want. - **Isolation flags.** The sandbox confines shell commands, not integrations, and a packet can carry injected instructions. `--ignore-user-config` skips your `config.toml` (and the MCP servers set there), `--ignore-rules` skips execpolicy rules that could allow a command outside the sandbox, and `features.apps=false` turns off apps, which are on by default. Plugins and admin-managed config can still apply. Login still works; it isn't in that file. - **`-o`** writes only the final message to a file. **`< /dev/null`** prevents a stdin hang. - **Sandbox:** `workspace-write` to implement, `read-only` to review. Never full access, never a `--dangerously-bypass-*` flag. - Outside a git repo, add `--skip-git-repo-check`. - **Put this in every packet:** "Do not remove or weaken any existing test." Codex's sandbox has no network by default, and some models delete tests they can't run or try workarounds when access is denied. - Run it in the background when the host allows it. ### Gemini (`agy -p`): plan mode, text out ```bash mkdir -p /handoff && cd /handoff && \ agy -p "$(cat /packet.md)" --model --sandbox --mode plan \ < /dev/null > /gemini-out.txt 2> /gemini-err.txt ``` - **Input files:** copy only the files it needs into the handoff folder, name them in the prompt, delete the copies afterwards. File content goes to Google. - **Code output:** end the spec with "Output ONLY code, no markdown fences, no commentary". Strip fences anyway, then write the result to the target file with a short script. - `agy -p` is an agent with tools. `--mode plan` stops it editing and `--sandbox` restricts its terminal. The handoff folder only decides what it is pointed at: **it is not a read boundary**, and `agy` has no switch to turn off your integrations. Send it only packets you wrote, never untrusted text. Use its text output only; it doesn't generate images. ### Claude: the `opus-implementer` subagent - **Host is Claude Code:** use the Agent tool with `subagent_type: "opus-implementer"` and the full spec. **Don't pass `model`**: a per-call model overrides the agent definition (Opus at medium effort). It spends Claude quota; what it saves is the host's context. It runs with **the host session's own permissions**, not a separate sandbox: the same prompts and rules as if the host did the edit. For OS-level confinement, turn on Claude Code's sandbox (`/sandbox`). - **Host is Codex:** run it as a CLI from the repo root. If the Codex session is sandboxed (`workspace-write`, not full access), the call runs inside that sandbox and inherits its write limits: ```bash cd && claude -p --agent opus-implementer --permission-mode acceptEdits \ "$(cat /packet.md)" < /dev/null > /claude-out.md ``` Codex's sandbox blocks network by default. **Don't approve the escalation**: an approved command runs outside the sandbox. Set `network_access = true` in `~/.codex/config.toml` instead (see the README), which keeps the sandbox. Without network, `claude` reports "Not logged in". - A user hook that writes outside the repo (a cache, a log) fails inside Codex's sandbox and can block the prompt while `claude` still exits 0. Check `claude-out.md`, not the exit code. If a hook is the cause, add `--settings '{"disableAllHooks":true}'` for this call only. - The agent reports back **only** the files changed and the check result, not the code. - **Claude as a read-only reviewer** (either host): no command tools, no user settings or MCP, file tools confined to the repo: ```bash cd && claude -p --restricted --strict-mcp-config --tools "Read,Grep,Glob" \ --model claude-opus-5-5 --effort medium --permission-mode plan --no-session-persistence \ "$(cat /packet.md)" < /dev/null > /review.md ``` ## 4. Write the spec Decisions already made. Name the file, the function, the imports, and what must not change. Bad, because it needs judgement the delegate doesn't have: > Add caching to the API layer. Good, because it is mechanical: > In `src/api/fetch.py`, wrap `get_user` in `functools.lru_cache(maxsize=512)`. Add > `import functools` with the other stdlib imports. Change nothing else in the file. Always end with the scope fence **"Change nothing else."** ## 5. The loop 1. **Judge.** Apply the four gates. If any fails, write the code in the host and say why in one line. 2. **Pick.** The user's named model, otherwise ROUTING.md (installed, not the host, another plan first). 3. **Scout** (only with Jev on, when 2b applies). 4. **Spec.** Include the scope fence. For Codex, add the test-safety line. 5. **Run.** On failure or quota-out, fall through to the next candidate; don't retry the same model. 6. **Verify.** Run the check. Read the diff. Confirm the scope was respected. 7. **Report.** Tell the user what went to which model, what came back and what needed fixing. Never present unverified output as done. If the output is wrong, decide once: re-delegate with a tighter spec, or fix it in the host. A second failure means the task wasn't delegable. **Cost note:** report the saving when it's material, e.g. "~200 lines typed on Codex quota; this session paid for the spec and the review." Don't claim a saving when the spec and review cost as much as the code would have. ```` ## File: skills/delegate/scripts/jev.py size: 9731 sha: 48e06336aa3455f5b1c256de190681da63da44d7 upstream: https://github.com/pvjbuilds/delegate-router/blob/main/skills/delegate/scripts/jev.py ```text # /// script # requires-python = ">=3.10" # dependencies = ["typesafe-sdk==0.7.2"] # /// """Optional Jev (TypeSafe) decision calls for delegate-router.

Benchmarks are a prior, not proof: **a check run on the actual task beats any benchmark.** Neutral benchmarks pick a new model's first route; before it takes that route, the maintainer runs it through the bench (`bench/` in the repo root) against the model that holds the route now. History: 2026-09-30 said "don't run trial calls to confirm them". 2026-10-27 the maintainer changed it to bench each new model on routine tasks. `git pull` in the repo brings a newer snapshot. `model_watch.py status` says when this file is more than 60 days old or when your CLIs list a model it doesn't cover yet. ## How to read a row Walk the candidates in order and take the first one that: 1. **is installed** (`model_watch.py status` lists the CLIs), 2. **is not the host's own model.** Same model, same quota: no gain. One exception: inside Claude Code, the `opus-implementer` subagent is allowed even when the host is Opus, because it keeps the file reads and tool turns out of the main context, and 3. **runs on another subscription than the host**, when the row has one installed. The subscription goes by CLI: `codex` is the OpenAI plan, `claude` and `opus-implementer` the Anthropic plan, `agy` the Google plan. This spreads the work across the plans you pay for. If no candidate on another plan is installed, take the first one on the host's plan and say so in one line. Two rows skip rule 3 and walk in plain order: - **Must be right**: correctness matters more than quota. - **Trivial edits**: a rename isn't worth a stronger model's quota; the cheap model stays first even on the host's plan. If nothing in a row qualifies, the host does the work itself. ## Default route | Task | Candidates, in order | CLI and model ID | Effort | |---|---|---|---| | **Bulk code** from a written spec: new module, boilerplate, test stubs, many-file mechanical edits | 1. GPT-6.1 Terra
2. GPT-6.1 Sol
3. Claude Opus 5.5 | `codex` · `gpt-6.1-terra`
`codex` · `gpt-6.1-sol`
`opus-implementer` · `claude-opus-5-5` | medium
high
medium | | **Must be right**: correctness matters more than quota, terminal-heavy agent work, or a spec the first pick already failed | 1. Claude Opus 5.5
2. GPT-6.1 Sol | `opus-implementer` · `claude-opus-5-5`
`codex` · `gpt-6.1-sol` | medium
high | | **Trivial edits**: reformatting, renames, mechanical find-and-replace | 1. GPT-6 Luna
2. Claude Opus 5.5 | `codex` · `gpt-6-luna`
`opus-implementer` · `claude-opus-5-5` | medium
medium | | **Images**: screenshots, scanned pages, charts (image files) | 1. GPT-6.1 Terra
2. Gemini 3.8 Flash | `codex exec -i ` · `gpt-6.1-terra`
`agy` · `gemini-3.8-flash-high` | medium
(in the ID) | | **Media and long reads**: PDF, video, audio, long documents | 1. Gemini 3.8 Flash
2. Claude Opus 5.5 | `agy` · `gemini-3.8-flash-high`
`opus-implementer` · `claude-opus-5-5` | (in the ID)
medium | | **Single-file text** with no repo access: a conversion, a fixture, a draft | 1. Gemini 3.8 Flash
2. GPT-6.1 Sol | `agy` · `gemini-3.8-flash-high`
`codex` · `gpt-6.1-sol` | (in the ID)
medium | | **Hard reasoning**: maths, proofs, algorithms, science, very large documents | 1. GPT-6 Astra | `codex` · `gpt-6-astra` | low, raise only if needed | | **Review**: security review, second opinion on a design or a diff | 1. GPT-6 Astra (read-only)
2. Claude Opus 5.5 (read-only) | `codex -s read-only` · `gpt-6-astra`
`claude -p --restricted` · `claude-opus-5-5` (SKILL.md has the full command) | low
medium | **Quota out.** A usage-limit error usually names its reset time. Say it in one line and fall through to the next candidate; don't stall. If a CLI call fails, report that model as missing, never quietly drop it. ## Why these picks In our own words; the numbers live on the trackers linked at the bottom. - **GPT-6.1 Terra** is the default typist since 2026-11-01, the maintainer's pick to spend fewer tokens. On our bench (`bench/`) it passed 10/10 on 2026-10-27, as GPT-6.1 Sol high did, on fewer tokens. It runs on the Codex plan's separate quota. After a failed run, escalate to GPT-6.1 Sol, then Opus, rather than retrying Terra. - **GPT-6.1 Sol** is the second typist. On independent intelligence indexes it lands close to Opus at medium effort for a fraction of the cost per task. On terminal and agentic coding trackers it leads Terra clearly, so it takes over when Terra fails a packet. - **Claude Opus 5.5 at medium effort** is the must-be-right choice and the fallback for everything. It leads on agentic tool use and production software engineering. Medium is its knee: each step up costs much more per point gained. - **Claude Sonnet 5.5 is not routed.** It is cheaper per token but uses far more tokens, so it costs more per task at equal quality. **Compare cost per task, not price per token.** - **GPT-6 Astra** leads on maths, science, abstract reasoning, very long-context retrieval and security work. It is slow and expensive, so it gets hard problems and reviews, not bulk typing. - **Gemini 3.8 Flash** is fast and cheap, and strong at video and other media. It is weak at multi-step agent work, so it runs in plan mode and only its text output is used. - **GPT-6.1 Terra** also reads images. Independent multimodal scores put it at or near the top of the field, and it is cheap per task. `codex exec -i` takes image files only, so PDF, video and audio stay with Gemini. - **GPT-6 Luna** is very cheap and fast but clearly weaker. Mechanical edits only. - **Not routed:** Claude Haiku 5.5 (`claude-haiku-5-5`; the strongest small model, but very verbose and it spends the Claude quota that cheaper Codex and Gemini tiers spare), Claude Haiku 4.5 (replaced by Haiku 5.5), Claude Fable 5.1 (Opus 5.5 scores higher and costs less), older GPT and Gemini tiers. ## Rules - **High effort is the ceiling for a delegate.** xhigh and max buy a few points at 2–3× the cost per task. - **Reviewers run read-only.** A packet can carry injected instructions; only an implementer gets write access. Codex delegates also skip your config and rules and turn apps off (see SKILL.md for the flags and what they don't cover). - **Caveats to put in every packet:** - Codex models: "Do not remove or weaken any existing test." Some GPT models try workarounds when access is denied, and Codex's sandbox has no network by default. - Gemini: reads media and returns text. It runs in plan mode, so don't ask it to edit files or run commands, and it doesn't generate images. - **Handoff overhead** (writing the spec, reading the report and the diff) is real. Worth it for another quota pool or for keeping the host's context clean; not worth it to move work to a model that costs more per task. ## When two models disagree (council) 1. **Blind first.** The reviewer gets the artifact and what it must satisfy, never the host's conclusion. 2. **Adversarial prompt:** "Find what is wrong. Don't validate. If nothing is wrong after a thorough look, say so explicitly." 3. **Classify each finding:** the brief was unclear → real, fix it → real trade-off, the user decides → noise. 4. **Tiebreak:** a benchmark lead settles it only if the question sits squarely in that model's lead area **and** the gap is bigger than the error bar. Otherwise run a check on the real task, or take it to the user. 5. **Three rounds at most**, then the user decides. ## Keeping this current - **For users:** `git pull`. The watch (`model_watch.py`) tells you when a release lands before this file catches up. With `AUTO_UPDATE_CLI=1` it also updates the CLI and proves the model answers. - **Release notes the watch reads:** the Codex changelog, OpenAI news, Anthropic's release notes, the Claude Code changelog and Google's Gemini API changelog. Plan access is decided by the vendor's own wording ("available in Codex and ChatGPT", "for Pro subscribers"). - **For the maintainer, on a new model (~15 min):** 1. Confirm plan access in the vendor's release notes. 2. Re-read the trackers below for every model in the table, not just the new one. 3. Bench it: `python3 bench/bench.py codex|claude|agy [effort]`, then the current holder of the route it would take. It takes the route only if it passes more tasks, or as many for no more cost. Results append to `bench/results.tsv`. 4. Redo the route table and "Why these picks". Bump the snapshot date. 5. For a new Opus, update `model:` in `agents/opus-implementer.md`. 6. Commit, then run `model_watch.py ack`. **Trackers**, in order of trust: [Artificial Analysis](https://artificialanalysis.ai) (runs its own evals, publishes cost per task) · [BenchLM](https://benchlm.ai) (per-field scores, shows uncertainty) · [llm-stats](https://llm-stats.com). Vendor launch posts pick favourable benchmarks. ``` ## File: README.md upstream: https://github.com/pvjbuilds/delegate-router/blob/main/README.md ````text

delegate-router workflow: your task goes to the host agent (Claude Code or Codex CLI), which judges it, picks a model from ROUTING.md (one on another of your subscriptions first), writes a spec, hands the packet to a delegate model (Codex, Gemini via agy, or a Claude subagent), and verifies the diff. The bench gates route changes, model_watch.py re-checks the routes every 12 hours, and the optional Jev scout picks the files for the spec.

# delegate-router: multi-model task delegation for Claude Code and Codex CLI **One agent thinks, another types.** delegate-router is an agent skill (SKILL.md, the Agent Skills format) for **Claude Code** and **OpenAI Codex CLI** that works as an LLM router for coding work. It hands bulky, already-decided work (boilerplate, scaffolding, test stubs, mechanical edits across many files, reading media and long documents) to another model you already pay for: **Codex** (GPT models), **Gemini** through the Antigravity `agy` CLI, or a **Claude Opus** subagent. The host keeps the design and the verification, and saves its own quota and context. - **Routing by task, not by habit.** [ROUTING.md](skills/delegate/ROUTING.md) maps each kind of task to an ordered list of models, chosen from independent benchmarks and cost per task. It skips any CLI you don't have, never routes back to the host's own model (except an Opus subagent under an Opus host, which keeps the main context clean), and prefers a model on another of your subscriptions, so the work spreads across the plans you pay for. - **A judge before every handoff.** Four gates (bulk, decided, verifiable, contained) and a never-delegate list (debugging, architecture, security code, anything under ~40 lines). - **The host always verifies.** A delegate's "done" isn't evidence: the host runs the check and reads the diff. - **Routes that keep up on their own.** Every 12 h, `model_watch.py` notices new models in your CLIs and the vendors' release notes, re-checks the routes against a fresh benchmark snapshot, and tells you when a route should change. A tracker rescaling its scores moves nothing; a model that really beats the holder does. **New in v1.4:** work goes to a model on another of your subscriptions first, so your main agent's quota isn't spent twice ([how](#which-model-does-it-pick-when-my-main-agent-is-codex)). Each route is judged on its own benchmark, and a route switches only on a cost per task measured on our bench ([how](#routes-that-keep-themselves-current)). See the [changelog](CHANGELOG.md). Interactive diagram: [docs/workflow.html](docs/workflow.html) (open it locally). ## Requirements - macOS or Linux, `git`, `python3` 3.9+. - **Your main agent is [Claude Code](https://code.claude.com/docs) (`claude`) or [Codex CLI](https://github.com/openai/codex) (`codex`)**, plus at least one more of Codex, Gemini through the [Antigravity CLI](https://antigravity.google) (`agy`), or Claude. Other main agents and other providers (DeepSeek, local models) aren't supported yet. Each CLI needs its own subscription or API access; delegate-router adds no accounts and no API keys. - Optional: [uv](https://docs.astral.sh/uv/) and a TypeSafe key, only for Jev. ## Install ```bash git clone https://github.com/pvjbuilds/delegate-router ~/.delegate-router ``` ```bash ~/.delegate-router/install.sh ``` Clone to a fixed path: the install links to it, so moving the folder later breaks the links. The installer finds your CLIs, links the skill, and asks a few questions. Enter takes the default; `--yes` takes every default. Re-running it keeps your earlier answers. | Question | Default | What it does | |---|---|---| | Install for Claude Code? | yes, if found | Links `~/.claude/skills/delegate`; no removes that link | | Install for Codex CLI? | yes, if found | Links `~/.agents/skills/delegate`; no removes that link | | Background checks for new models? | yes | At most every 12 h, only when the skill runs. No daemon, no cron. | | Update the CLI and probe a new model? | no | Updates through the channel the CLI came from (Homebrew cask, npm, or its own updater), then sends a one-word, read-only probe | | Turn on Jev? | no | See [Jev](#jev-optional) | If `claude` is installed, the installer also links the `opus-implementer` agent into `~/.claude/agents`: both hosts use it to reach Claude Opus. It never overwrites a file or folder that isn't its own, and never edits your Claude Code or Codex settings. It prints two optional snippets instead: - **Codex as host.** Codex's sandbox blocks network by default, so calling the `claude` CLI from inside Codex asks for approval. Don't approve it: an approved command runs outside the sandbox. Instead add to `~/.codex/config.toml`, which keeps the sandbox on: ```toml [sandbox_workspace_write] network_access = true ``` - **Claude Code session-start notice.** A `SessionStart` hook that runs `model_watch.py status`, so new-model notices show when a session opens. Restart Claude Code or Codex after installing. ### Install with an AI agent Paste this into Claude Code or Codex: > Install delegate-router: clone https://github.com/pvjbuilds/delegate-router to > ~/.delegate-router, run `~/.delegate-router/install.sh --yes`, show me the two snippets it > prints, and tell me to restart. `--yes` takes every default and asks nothing. The agent should not apply the printed snippets for you: they change your own settings. ## Use Ask the host to delegate, or type `/delegate`: > Delegate this: add typed stubs for the 14 endpoints in `api/routes.py`, one per function, > each raising `NotImplementedError`. The host judges the task, picks the model, writes the spec, runs the delegate, reads the diff and reports back: what went where, what came back, what it fixed. Name a model to override the map ("send this to Gemini"). ## Routing, briefly | Task | First choice | Fallback | |---|---|---| | Bulk code from a spec | GPT-6.1 Terra (Codex) | GPT-6.1 Sol, then Claude Opus 5.5 | | Must be right, or the first pick failed | Claude Opus 5.5 | GPT-6.1 Sol | | Trivial mechanical edits | GPT-6 Luna (Codex) | Claude Opus 5.5 | | Images, screenshots, scanned pages | GPT-6.1 Terra (Codex) | Gemini 3.8 Flash | | PDFs, video, audio, long documents | Gemini 3.8 Flash (agy) | Claude Opus 5.5 | | Hard reasoning, security review (read-only) | GPT-6 Astra (Codex) | Claude Opus 5.5 | Your main agent's own plan is skipped where the row has an alternative, so the work lands on another subscription: on a Codex host, bulk code goes to Claude Opus 5.5; on a Claude Code host, it stays on GPT-6.1 Terra. **Must be right** and **Trivial edits** keep their order on every host. To keep your own plan first, say so in your [LOCAL.md](#your-own-rules). The reasons, effort levels, caveats and the council protocol for when two models disagree are in [ROUTING.md](skills/delegate/ROUTING.md). Benchmarks are a prior; a check on the real task beats them. ## Staying current ```bash git -C ~/.delegate-router pull ``` That brings new rules, tasks and bench results. Between releases, `model_watch.py` tells you what's new, routes included: ```bash python3 ~/.delegate-router/skills/delegate/scripts/model_watch.py status ``` - `status` makes no network calls itself. It lists your delegate CLIs, any new release it found, and any model your CLIs list that ROUTING.md doesn't cover yet. With background checks on, it also starts `run --if-due` in the background, which goes online at most every 12 h. - `run` does the checking: model catalogs (`codex debug models`, `agy models`, Anthropic's models page) and five vendor release-note pages. It's capped at 10 names, and every step, CLI update and probe included, stops at 15 minutes. - `ack` marks everything current as reviewed. ### Routes that keep themselves curre ````
