+Downstream applications like `llama-server` can then make informed decisions about special token parsing based on the `is_input` flag. In `libcommon`, `common_chat_templates_apply()` returns these parts as `common_chat_params::prompt` (see `common_chat_prompt` in `common/chat.h`).

 **Caveats:**
 - Special tokens dynamically constructed from user input will not function as intended, as they are treated as user input. For example: `'<|' + message['role'] + '|>'`.

+### Authentication
+
+A server started with `--api-key` (or any OpenAI-compatible endpoint behind a
+token) needs one here too. `--api-key` is sent as `Authorization: Bearer` on
+every eval request; it falls back to `$LLAMA_API_KEY`, which keeps the secret
+out of your shell history and off the process list.
+
+```bash
+# One key for every server
+python3 llama-eval.py --server http://localhost:8033 --api-key sk-... ...
+
+# From the environment
+export LLAMA_API_KEY=sk-...
+python3 llama-eval.py --server http://localhost:8033 ...
+
+# One key per server, in --server order
+python3 llama-eval.py \
+  --server http://server1:8033,http://server2:8033 \
+  --api-key sk-one,sk-two --threads 16,16 ...
+```
+
+The LLM grader authenticates too. It reuses the key of the server it runs on,
+so `--grader-type llm` without `--grader-server` needs nothing extra; a grader
+on a separate endpoint takes `--grader-api-key`.
+
+Endpoints on an opencode host additionally get an `x-opencode-session` header,
+generated fresh for every task. An agentic episode sends the same id on all of
+its turns, so opencode sees one session per task instead of one per request;
+other servers never see the header.
+
+## Agentic suite
+
+`--dataset agentic` is a different shape from the other code suites. It runs
+**SACB** (Simple Agent Coding Benchmark), hosted at
+[`ilintar/SACB`](https://huggingface.co/datasets/ilintar/SACB) -- 60 tasks over
+three hand-written repositories, in Python and TypeScript. Rather than
+answering one prompt, the model is given a small but real repository, a
+deliberately narrow tool set, and a bug report, and drives its own multi-turn
+conversation until it declares itself finished. It is then graded by running a
+test suite it was never allowed to see.
+
+```bash
+python3 llama-eval.py \
+  --server http://localhost:8033 --model my-model \
+  --dataset agentic --threads 1 --temperature 0
+```
+
+### The tools
+
+| tool | purpose |
+|---|---|
+| `list_files` | enumerate the tree |
+| `read_file` | read, with 1-based line numbers and optional line-range narrowing |
+| `search` | regular-expression search across the repository |
+| `edit_lines` | replace an inclusive line range |
+| `edit_replace` | replace an exact snippet, which must be unique |
+| `write_file` | write a whole file |
+| `lint` | run the language's linter and type checker |
+| `finish` | declare the change complete |
+
+Three constraints are deliberate:
+
+**There is no shell and no way to run the tests.** The only feedback channel is
+`lint`. A syntax or type error can be driven out mechanically; a logic error has
+to be reasoned about. A harness that lets an agent iterate against the test
+suite measures something closer to search than to understanding.
+
+**There are two edit tools**, one line-addressed and one content-addressed.
+Which one a model reaches for, and whether it keeps line numbers straight after
+its own earlier edit, is itself a signal.
+
+**The tests never touch the working tree.** They are held outside it and copied
+into a throwaway copy only after the agent has stopped, so they can be neither
+read nor edited. Every tool path is resolved and confinement-checked against the
+repository root, so a symlink planted inside the tree cannot reach outside it.
+
+### Scoring
+
+A task is **resolved** when every test that was failing now passes *and* nothing
+that was already passing broke. Both sets are derived by running the tests twice
+when the corpus is built -- once against the defective tree and once against the
+reference fix -- never hand-written, so a task whose defect no test exercises is
+rejected rather than shipped.
+
+Because many tasks contain several independent defects, the fraction of target
+tests passed is reported alongside, which separates "fixed two of the three
+faults" from "changed nothing". Process metrics are reported too: turns, tool
+calls, rejected calls, edits, and the peak conversation size.
+
+### Dependencies
+
+Nothing here is installed unless you select this suite, and then only for the
+language you actually run. `--agentic-lang python` provisions ruff and mypy;
+`--agentic-lang typescript` provisions the TypeScript compiler and uses node's
+own test runner. Neither touches the other, and no other suite touches either.
+
+### Useful flags
+
+| flag | meaning |
+|---|---|
+| `--agentic-lang` | restrict to one language, and provision only its toolchain |
+| `--agentic-max-turns` | give up after this many assistant turns (default 50) |
+| `--agentic-max-tokens` | cap generation per turn (default: no cap); bounds a model that falls into a repetition loop, but also cuts reasoning off mid-thought. Truncated turns are counted as `truncated_turns` |
+| `--agentic-context-limit` | abandon an episode once its context exceeds this many tokens |
+| `--agentic-transcripts DIR` | save each episode's full message history to `DIR/<task_id>.json`, plus a `DIR/<task_id>.html` showing every reasoning block, reply, tool call and tool result; the main report links to it |
+
+
+## Code suites (HumanEval, ClassEval)
+
+`--dataset humaneval` runs the 164 OpenAI HumanEval problems; `--dataset
+classeval` runs the 100 ClassEval class-generation tasks. Unlike the other
+suites these are not graded by matching text: the model's reply is parsed for a
+```` ```python ```` block, that code is combined with the task's own unit tests,
+and the result is **executed**.
+
+ClassEval asks for a whole class rather than one function, so it is scored the
+way upstream does - **class level** (every one of the task's tests passes, which
+is what feeds pass@k) and **method level** (what fraction of all 2196 test
+methods passed). The second number separates "generated nothing usable" from
+"got most of the class right", and both are printed at the end of a run.
+
+Give it more room to generate than HumanEval - a class with ten methods does not
+fit in a short budget:
+
+```bash
+python3 llama-eval.py \
+  --server http://localhost:8033 --model my-model \
+  --dataset classeval --threads 8 --n_predict 4096 --temperature 0
+```
+
+```bash
+# pass@1, greedy
+python3 llama-eval.py \
+  --server http://localhost:8033 --model my-model \
+  --dataset humaneval --threads 8 --n_predict 1024 --temperature 0
+
+# pass@10 -- each extra multiple of 164 is another sample per problem
+python3 llama-eval.py \
+  --server http://localhost:8033 --model my-model \
+  --dataset humaneval --n_cases 1640 --temperature 0.8 --top-p 0.95
+```
+
+`--grader-type exec` is the default for code suites, so neither it nor
+`--dataset-source` normally needs to be passed.
+
+### Execution sandbox - no Docker required
+
+Generated code is untrusted, but these suites need far less than a container to
+run safely. **The package set is derived from the dataset's own imports at
+startup**, not hardcoded and not taken from the upstream `requirements.txt` -
+which for ClassEval lists `torch`, `openai` and `transformers` that its *tests*
+never touch. So each suite installs exactly what it needs:
+
+| suite | third-party packages |
+|---|---|
+| HumanEval | **none** - every problem imports only stdlib (`typing, math, random, copy, string, collections, hashlib, re`) |
+| ClassEval | 13: `beautifulsoup4, gensim, lxml, netifaces, nltk, numpy, openpyxl, pandas, pillow, pypdf2, python-docx, reportlab, scipy` |
+
+Two of ClassEval's are *declared* rather than derived, because no import
+statement mentions them: `lxml` is selected by string
+(`BeautifulSoup(html, 'lxml')`, ClassEval_44 - without it that task silently
+drops from 23/23 to 7/23), and `scipy` is a hard gensim requirement. Note also
+that `PyPDF2` must **not** be modernised to `pypdf`: ClassEval_69's test imports
+`PdfFileReader`, a name pypdf removed.
+
+The venv is cached under `~/.cache/llama-eval/` (override with
+`LLAMA_EVAL_CACHE`) and rebuilt only when the package set, interpreter version
+or provisioning steps change; force one with `--rebuild-sandbox`. `uv` is used
+when available, which makes even the ClassEval venv build in seconds.
+
+**Interpreter selection.** A suite can prefer a different Python than the one
+running the tool, and declares it: ClassEval asks for 3.13, because gensim
+publishes no wheel past cp313 and its generated C no longer compiles on 3.14
+(it still uses `PyLongObject.ob_digit`). That interpreter is found automatically,
+including via `uv python`; `--sandbox-python` overrides it.
+
+3.14 is fully supported anyway. ClassEval uses exactly two gensim APIs
+(`utils.decode_htmlentities`, `matutils.unitvec`), both pure Python upstream, so
+on 3.14+ the suite drops gensim from the install set and provisions a small shim
+instead. Both paths score **100/100**.
+
+**Offline provisioning.** A suite that would otherwise fetch data at test time
+declares a provisioning step that runs once at venv build time, while the
+network is still up. ClassEval uses this to pre-seed exactly three nltk corpora
+(`punkt_tab`, `averaged_perceptron_tagger_eng`, `wordnet`, ~33 MB), so the tests
+themselves run with no network at all. Those are the *current* names - the
+dataset asks for `punkt` and `averaged_perceptron_tagger`, which nltk has since
+renamed, and seeding the legacy names too is not harmless: with a network
+available nltk considers them satisfied and re-fetches the modern ones anyway.
+The corpora are written *inside* the venv, not `~/nltk_data`, because `$HOME` is
+a tmpfs under the strongest isolation tier.
+
+Each candidate program runs in a throwaway directory as its own process group,
+under the strongest isolation the host offers:
+
+| tier | requires | isolates |
+|---|---|---|
+| `bwrap` | bubblewrap installed | read-only root, tmpfs `/tmp` and `$HOME`, **no network** |
+| `unshare` | `unshare --map-current-user` | **no network** |
+| `unshare-root` | any `unshare -r` | no network, but **runs as uid 0** - see below |
+| `rlimit` | always available | cpu/memory/file-size/process caps only |
+
+**Candidate code must not run as root**, which is why `unshare -r` is a
+last-resort tier that prints a warning. Root bypasses file permission bits, so a
+test asserting that writing to a `chmod 0444` file *fails* instead sees it
+succeed - ClassEval_50 scores 14/16 under uid 0 and 16/16 under uid 1000, with
+nothing in the output to suggest the sandbox caused it. Install bubblewrap.
+
+All tiers additionally cap CPU time, address space (4 GiB), file size and core
+dumps, and kill the whole process group on timeout (`--exec-timeout`, default
+15 s - raise it for ClassEval, whose tests do real work). Writes to the
+throwaway working directory are allowed, which is all the file-handling tasks in
+ClassEval need.
+
+Note that the weakest tier does not contain filesystem access. If you are
+scoring output from a model you do not trust, check the tier printed at startup.
+
+### Reproducibility
+
+Several tasks draw their test inputs from the *global, unseeded* RNG, so a
+verdict is not reproducible run to run - which adds noise exactly when you are
+comparing two models or two quantisations. `--exec-seed` (default `0`) seeds the
+RNG before each test; pass `--exec-seed -1` for the stock upstream behaviour.
+This does not change what the model is asked to compute.
+
+It matters more than it sounds. HumanEval/38, /50 and /53 are affected, and
+ClassEval_58 (duplicate mine placement) fails about 30% of the time on its own
+*reference* solution - measured here at 21/30 passes unseeded versus **30/30
+seeded**.
+
+### Dataset fidelity
+
+The canonical dataset runs **unmodified on current Python** - all 164 reference
+solutions pass on CPython 3.14 with no patches, so no forked or re-hosted copy
+is needed. `--dataset-source` accepts a local `.jsonl` or a HuggingFace repo id
+if you do want to point at a modified copy.
+
+HumanEval does contain a handful of long-standing defects where the *prompt*
+contradicts the graded test (notably HumanEval/47, /116 and /148). Those
+penalise a model that reads the docstring carefully, but correcting them makes
+the benchmark marginally easier and the resulting scores no longer comparable
+with published HumanEval numbers, so nothing is patched by default.
+
+ClassEval is different: the upstream data has defects that cap the achievable
+score below 100% for reasons unrelated to the model, so `--dataset classeval`
+defaults to a **patched fork**,
+[`ilintar/ClassEval`](https://huggingface.co/datasets/ilintar/ClassEval).
+Six edits over five tasks lift the reference solutions from 96/100 classes and
+2182/2196 test methods to **100/100 and 2196/2196**. Three repair tests nothing
+could pass:
+
+- **ClassEval_17** was a time bomb - a hard-coded 2024 date checked against
+  `datetime.now()`, unpassable since January 2024.
+- **ClassEval_48** asserted `get_hostname('0.0.0.0') == 'LAPTOP-2CS86KUM'`, the
+  dataset author's own machine name.
+- **ClassEval_31** compared floats with `assertEqual`, failing on a 4-ULP numpy
+  difference.
+
+The other three fix only the *reference* solutions (NumPy 2.0 removals in
+ClassEval_51, a 30%-flaky mine generator in ClassEval_58) and cannot affect a
+model's score. No `skeleton` was touched, so what the model is asked to write is
+byte-identical to upstream. Pass `--dataset-source FudanSELab/ClassEval` for the
+unpatched original.

+The existing code suites are single-shot -- one prompt, one reply, execute,
+grade. This one is not. The model is given a small but real repository and a
+deliberately narrow tool set, and has to find its way to the defect before it
+can fix it. That shape is what puts a run in the tens-of-thousands-of-tokens
+range without any artificial padding: the context grows because the model
+chose to read things.
+
+Three deliberate constraints:
+
+* No shell, and no way to run the tests. The only feedback channel is `lint`.
+  A syntax or type error can be driven out mechanically; a logic error has to
+  be reasoned about. Suites that let an agent iterate against the test suite
+  measure something closer to search than to understanding.
+* Two edit tools, one line-addressed and one content-addressed. Which one a
+  model reaches for, and whether it keeps line numbers straight after its own
+  earlier edit, is itself a signal.
+* Tests never touch the working tree. They are held outside it and copied in
+  after the agent has stopped, so they can be neither read nor edited.
+
+Everything here is imported lazily by llama-eval.py, and every dependency it
+needs is scoped to the language actually under test, so none of it is
+installed for anyone running the other suites.

+SYSTEM_PROMPT = """You are an expert {lang} engineer working in an existing repository.
+
+Resolve the user's request by editing files with the tools provided.
+
+How this session works:
+- You are working autonomously. There is no human watching; nobody will answer
+  questions, approve a plan, or read progress reports.
+- Every reply you send must contain at least one tool call until the task is
+  done. A reply that contains only text does nothing: no work happens and the
+  turn is wasted. Do not stop to describe what you are about to do; do it.
+- The session ends only when you call `finish`. Call it once the change is
+  made, and not before. Only the files as you leave them are evaluated.
+
+Important constraints:
+- You cannot run the code, the tests, or any shell command. The only feedback
+  available is the `lint` tool, which reports syntax and type problems.
+- The repository already has a test suite that will be run against your work
+  after you finish, but you cannot see it or run it. Do not create test files.
+- Read enough of the code to understand it before editing. A change that only
+  makes the symptom go away will usually fail the tests.
+- Make the smallest correct change. Do not reformat or refactor unrelated code.
+
+Keep calling tools until the change is complete, then call `finish`."""
