Take the offer — step 4 needs a run. Read the score the way the skill +does: a **1.000 on a first attempt means re-read the criteria**, not celebrate, and +a failure is a question about *which layer* is wrong (the prompt, or the skill or +tool it depends on) before it is a prompt edit. + +Now review what you already have.

An armed criterion's definitive effective FAIL — a native live-fail, or the decide_within timeout expiring — may end the run under the weighted ceiling rule (deferred while any pass-capable armed criterion is still undecided); set on_pass: stop to also end the run on a live PASS. An empty block (stop_early: {}) is the idiomatic distractor arming: fail-stop on misfire, nothing else.

When False the judge is NOT spawned — the criterion returns a skipped result (score=1.0, details='(skipped: enabled=false)') with no LLM cost. Useful for A/B comparisons across experiment variants where you want to keep the criterion in the YAML but not run it under a specific variant. | +| `files` | Paths whose contents are pre-attached to the judge prompt. Plain entries are sandbox-relative; entries prefixed with '$TASK_DIR/' are read from the host filesystem relative to the task YAML's parent directory (useful for shared rubrics outside the sandbox). Missing files are rendered as '' so the rubric can penalize them. Empty by default — without entries, the judge inspects the sandbox copy via its tools instead. | +| `include_reference` | When true (default) and task.reference is set, mount the reference for the judge. For ``code`` / ``file`` references, the content is inlined into the prompt. For ``directory`` references, the tree is copied into ``_reference/`` in the judge's working dir for Read/Glob browsing. Silently omitted if no reference is configured. Set to false if a reference is configured for ``reference_comparison`` only and should NOT be visible to the LLM grader. | +| `include_agent_output` | Include the latest agent turn's raw output in the judge prompt (UNTRUSTED). Default false because agent_judge has live tool access to the sandbox copy and can ``Read`` the agent's files directly — inlining narration is usually redundant. | +| `include_tool_calls` | Include summarized tool-call telemetry from the latest agent turn. | +| `include_dialog` | Include the full user<->agent conversation across all turns. In simulation mode the user side is generated by an LLM simulator and may invent premises — the judge should treat any claim made only by the simulated user as possibly fabricated, and not penalize the agent for going along with it unless the task description contradicts it. | +| `max_dialog_chars` | Aggregate cap on dialog text rendered into the judge prompt. Prevents an N-turn simulation from blowing out the judge's context window. Per-message truncation uses max_file_chars; trailing turns are dropped when this aggregate budget is exceeded (a degraded note is recorded). | +| `max_file_chars` | Per-message truncation budget for trajectory blocks (agent_output, dialog turns). agent_judge no longer pre-attaches files — the judge reads them via its tools — so this only applies to trajectory injection. | +| `max_turns` | Inner-loop turn limit for the judge agent. Generous default — typical judge runs use 5-15 turns; the cap mostly matters when grading complex multi-file solutions where the judge needs to read across many files. ``turn_timeout`` (default 300s) bounds wall-clock per turn, so the practical cost cap is tokens, not time. | +| `turn_timeout` | Wall-clock timeout for the judge turn (seconds). Minimum 10. | +| `agent` | Judge agent configuration (built-in kinds only — agent_judge runs a Claude Code sub-agent). Defaults to a sonnet, bypass-permissions, read-only toolkit suitable for investigation-style judging. Override fields per task as needed. For security, the judge always runs with setting_sources=[] regardless of what this field declares — see _build_agent_config. | +| `capture_transcript` | When true, persist a ``JudgeTranscript`` (tool calls + token usage + raw verdict + rendered prompts) to a sibling ``judge-.yaml`` file next to ``task.json``. Set to false to drop the transcript when on-disk size matters (e.g. 1000-row datasets). The verbose ``findings`` field on the result is persisted regardless — only the trajectory log is gated by this flag. | +| `max_transcript_chars` | Aggregate cap on captured transcript text (raw_verdict + judge_prompt + judge_system_prompt + tool detail / result_preview lines). Budget is split 60% verdict / 30% prompt / 10% system, with tool calls taking priority. Truncation marks the transcript as ``truncated=True``. | + +### `classification_match` + +Match a single label written by the agent to a file against ground truth. + +| Field | What it is | +| --- | --- | +| `path` | Path to the file (relative to sandbox) containing the agent's predicted label | +| `expected_label` | Ground-truth label for this row | +| `allowed_labels` | Canonical label set. File content not in this set is treated as '(other)'. | + +Optional: + +| Field | What it is | +| --- | --- | +| `case_sensitive` | When False (default), matching is case-insensitive and labels are canonicalised. | + +### `command_executed` + +Check whether the agent executed specific commands/tools. + +Optional: + +| Field | What it is | +| --- | --- | +| `tool_name` | Tool name filter (e.g., 'Bash'). None = any tool. | +| `command_pattern` | Regex to match command parameters.

When False the judge is NOT called — the criterion returns a skipped result (score=1.0, details='(skipped: enabled=false)') with no LLM cost. Useful for A/B comparisons across experiment variants where you want to keep the criterion in the YAML but not run it under a specific variant. | +| `files` | Paths whose contents are shown to the judge. Plain entries are sandbox-relative; entries prefixed with '$TASK_DIR/' are read from the host filesystem relative to the task YAML's parent directory (useful for shared rubrics outside the sandbox). Missing files are rendered as '' so the rubric can penalize them. | +| `include_reference` | When true (default) and task.reference is set, include the reference solution in the judge prompt. Silently omitted if no reference is configured. Never shown to the agent. Set to false if you want the reference to drive a non-judge consumer (e.g. ``reference_comparison``) without showing it to the LLM grader. | +| `include_agent_output` | When true, include the latest agent turn's raw output in the judge prompt. Wrapped as UNTRUSTED DATA. No-op when turn_records is unavailable. Default false because the agent's narration is usually redundant with the files it produced (declared via ``files`` or visible to the agent_judge via tool access). | +| `include_tool_calls` | When true, include a summary of the latest agent turn's tool calls (via summarize_commands). No-op when turn_records is unavailable. | +| `include_dialog` | When true, include the full user<->agent conversation across all turns in the judge prompt. In simulation mode the user side is generated by an LLM simulator and may invent premises — the judge should treat any claim made only by the simulated user as possibly fabricated, and not penalize the agent for going along with it unless the task description contradicts it. | +| `max_dialog_chars` | Aggregate cap on dialog text rendered into the judge prompt. Prevents an N-turn simulation from blowing out the judge's context window. Per-message truncation uses max_file_chars; trailing turns are dropped when this aggregate budget is exceeded (a degraded note is recorded). | +| `model` | Judge model id (e.g. 'anthropic.claude-sonnet-4-6'). On a BedrockRoute / DirectRoute the value is auto-translated: trailing '-vN[:M]' suffixes and the 'anthropic.' prefix are stripped where the backend doesn't accept them; on Bedrock the cross-region inference-profile prefix is added based on AWS_REGION. | +| `temperature` | Sampling temperature for the judge model. 0.0 keeps grading deterministic. | +| `max_tokens` | Output token cap. Defaults to 2000 — large enough for the verbose verdict (score + rationale + a handful of findings) without runaway. | +| `max_file_chars` | Per-file content truncation applied before building the prompt. | +| `capture_transcript` | When true, persist a ``JudgeTranscript`` (raw verdict + rendered prompts + token usage) to a sibling ``judge-.yaml`` file next to ``task.json``. Set to false to drop the transcript when on-disk size matters (e.g. 1000-row datasets). The verbose ``findings`` field on the result is persisted regardless — only the per-call transcript file is gated by this flag. | +| `max_transcript_chars` | Aggregate cap on captured transcript text (raw_verdict + judge_prompt + judge_system_prompt, plus tool-call detail / result preview lines for agent_judge). Budget is split 60% verdict / 30% prompt / 10% system.

Establish the subject before applying them. + +Signals that a task's subject is the framework rather than an agent: `agent: {type: none}`; a +`smoke`-style tag; a criterion whose satisfaction is produced by `pre_run`, by the container +image, or by `template_sources`; or a description that names a framework mechanism instead of +a capability. + +For those tasks: + +- **Check 3 does not apply.** Reading back what the setup wrote *is* the measurement — a + criterion satisfiable by "inaction" is the correct design, not a no-op detector. +- **A prompt that names the exact string a criterion greps for is correct**, not the + can't-fail trap.

Could this pass for the wrong reason? + +The framing question, asked before anything else: + +> **What is the cheapest thing an agent could do that scores full marks?** + +Answer it out loud. If the cheapest path does not resemble the work the task claims to +test, the criteria are wrong — not the agent. Then walk the mechanical checks: + +| # | Check | Fix | +|---|---|---| +| 1 | Does a `command_executed` criterion credit an invocation that **failed**? | Set `require_success: true` whenever the command's success is what is being graded. The default is `false`, which counts a crashed invocation as evidence the work was done. | +| 2 | Does the pattern also match a help probe, or a longer word that contains it? | Add `exclude_pattern` and word boundaries. Cover **both** `--help` and `-h`; an agent that runs `tool --help` and gives up otherwise satisfies a bare `tool` pattern. | +| 3 | Would an agent that does **nothing** pass? | List the criteria satisfiable by inaction — `min_count: 0`, a `max_count: 0` negative, a `file_exists` on a file the setup already created. A task passes only when **every** scoring criterion (`weight` above 0) meets its own `pass_threshold`, so if inaction satisfies all of them the task is a no-op detector. If it satisfies only some, total their `weight` against the task's: that share is how much of the score is free. | +| 4 | Does a regex alternation launder the assertion? | An alternation branch that makes the payload opaque — matching an indirection flag such as `--from-file` instead of the content that flag points at — proves nothing. Keep the shape criterion on the shape-visible form and add a companion check on the payload itself. | +| 5 | Does `min_count` express a *count* where the description promises distinct *content*? | Assert the distinct content. Three calls to the same endpoint satisfy `min_count: 3` and demonstrate none of the coverage the description claims. | +| 6 | Is the end state reachable without the system under test? | Ask whether local file manipulation alone could satisfy every criterion. If an agent could hand-write the expected output instead of calling the tool, the tool is not being tested. | +| 7 | Does a criterion match a literal the **prompt already dictates**? | Then it cannot fail — the agent was told the answer, and you are grading transcription. Either the literal is a real requirement (keep it in the prompt and score what the agent *did with it*) or it is the thing under test (drop it from the prompt). Never both. See section 0 first: for a framework-plumbing task a dictated literal is the correct design. | + +*Seen in the wild:* every one of these has shipped in a real suite and passed review. +Check 1 is the most common by a wide margin — the field defaults to the permissive value, +so it is what you get by not thinking about it. Check 3 is the most expensive, because a +no-op detector reports a healthy score forever and nobody looks at it again. + +## 2. Does anything check the output's *content*? + +At least one criterion must inspect what the output **says**, not merely that it exists. A +suite of `file_exists` checks passes when the agent writes an empty file, and `touch out.json` +satisfies every one of them. + +Exempt (see section 0): a framework-plumbing task whose subject is that a file arrives at all, +and a classification suite whose rows have no artifact to inspect — there the aggregate across +rows is the content check. + +## 3. Grade behaviour, not self-reports + +A criterion that reads a file the prompt asked the agent to write *about its own work* +grades a claim, not an outcome. "Write a summary of the changes you made to `report.md`" +plus a criterion checking `report.md` mentions the change tests whether the agent can +describe itself, which it can. + +Grade the artifact the work produced, or the command that produced it. If a self-report is +genuinely the deliverable, then something else must independently establish the facts it +reports. + +*Seen in the wild:* a task whose only content check read the agent's own changelog entry. + +## 4.

Two failure shapes: + +- **The judge is the only signal.** A single `llm_judge` at high weight means the task's + verdict is one model's opinion, re-rolled on every run. Add deterministic criteria for + everything checkable and let the judge grade only the part that genuinely needs judgement. +- **The rubric conjoins N conditions at `pass_threshold: 1.0`.** This is the + highest-variance shape available: every condition must land in one generation, so the + score swings on wording. Split it into one criterion per condition, each independently + scored and weighted. + +*Seen in the wild:* a six-clause judge rubric at `pass_threshold: 1.0` that scored +anywhere from 0.4 to 1.0 across identical runs. + +## 5. Scope match + +Read `initial_prompt` and `description` against the criteria as a set: + +- Everything the prompt **asks for** should be graded. An ungraded instruction is either + dead prompt text or a silent coverage hole. +- Everything the description **claims** should be exercised. A task described as testing + error handling whose criteria only check the happy path is mis-labelled, and the label + is what people trust when they read a suite summary. + +Deleting a criterion without trimming the prompt is the usual way this drifts — the prompt +still asks, nothing still checks. + +*Seen in the wild:* a task whose prompt asked for three output files after the criteria for +two of them had been removed as flaky. It scored 1.0 while testing a third of its subject. + +## 6. Fixture lifecycle + +**This section is the canonical home for these checks.** The skills that *apply* this rubric +point here rather than restating them. (`/coder-eval:analyze` separately diagnoses the same +failure from the other end — a finished run's residue signature — which is a different job +from reviewing a task file, so it states its own version.) + +It fires only when a task touches state **outside** the sandbox — a tenant, a hosted +service, a shared account, a remote registry. A task confined to its own temporary +directory is exempt: the sandbox is the reset. + +- **`pre_run` resets to a known state; `post_run` cleans up.** Removing either is how a + task self-poisons: one bad run leaves residue, and the criterion then fails on every + subsequent run forever. A task that passes once and fails permanently afterwards is the + signature. +- **Grade "the agent did it *this run*", not "the state is right now."** End-state grading + false-passes when something else already produced the state, and false-fails when + something else undoes it mid-run. Gate on evidence the agent itself produced — its + commands, its output files — and keep the end-state re-read as a complementary, + lower-stakes check. +- **Run-unique fixture names.** A fixed name collides with a concurrent run and inherits + stale residue from a crashed one. A date-stamped name is a throwaway that accumulates + inside a permanent account. +- **Cleanup must be reachable on the failure path.** Record each identifier as it is + created, not after the last one succeeds — otherwise a failure mid-sequence orphans + everything created before it. `post_run` commands do not affect pass/fail, so they still + run when the task fails; that is what makes them the right place for teardown. +- **Ordering contract.** Experiment-defaults `pre_run` runs first (baseline setup), then + the task's.

Then, for each task it +explains, replace those issues with a bare reference to the theme rather than restating them; +when every issue on a task is theme-captured, the task collapses to a one-line entry naming the +themes and no per-task severity of its own. + +**A theme never lowers a severity.** Clustering changes where a finding is *reported*, not how +bad it is — and the summary counts every issue once, at the severity of the theme that owns +it.

None → say so and stop. +- A directory: use the `SKILL.md` inside it. +- A name: find the matching skill directory. + +The **bare skill name is the directory name** containing `SKILL.md`. Read the +frontmatter `description` and keep it in front of you: that string is what the model +matches against, so it is the primary input to row design and the thing you will end +up recommending edits to. + +**Measure its length while you are there — two separate budgets truncate it, and either +one produces a low-recall result that looks exactly like bad wording.** + +1. **Per-skill truncation.** `description` and `when_to_use` are concatenated and cut at a + fixed character budget — **1,536 characters**, configurable via the + `skillListingMaxDescChars` setting. Trigger text past the cutoff cannot affect + activation at all, so it may as well not exist. +2. **The whole-listing budget, which matters more in exactly the repositories that run + activation suites.** The listing always contains every skill *name*, but its total + character budget scales at about **1% of the model's context window**, shared across + **every** skill the user has installed. When it overflows, Claude Code drops + descriptions **starting with the skills you invoke least**. + +The second one has a consequence worth stating plainly: in a many-skill repository a skill +can score near-zero recall with a **perfectly good description**, because its description +was never in the listing. Rewriting the wording then fixes nothing. And the drop order is +least-invoked-first, so a *newly authored* skill — which is by definition rarely invoked, +and is exactly what someone runs this suite on — is the most likely victim. That is a +systematic bias against the skill under test. + +Levers, if the listing is the problem: `skillListingBudgetFraction` (the 1% default), the +`SLASH_COMMAND_TOOL_CHAR_BUDGET` environment variable (a fixed character count), and +`skillOverrides` set to `"name-only"` to free budget from skills you do not need matched. + +If the skill has **no `description`** in its frontmatter, stop and report that as the +finding — a skill with no description can never be model-invoked, so a suite would +score zero recall by construction and tell you nothing you don't already know. + +## Step 2 — Confirm coder-eval is installed + +Run `coder-eval --version`. Installing this plugin did not install the CLI, and the +suite cannot be validated or run without it. + +If it is missing, follow `${CLAUDE_PLUGIN_ROOT}/reference/cli-setup.md`: offer the +install, **ask before running it**, and confirm with `coder-eval --version` +afterwards. Never install unprompted, and do not continue if the user declines. + +## Step 3 — Design the rows + +This step is the whole experiment. The rest is mechanics. + +**Positive rows** — requests a real user would plausibly make that the description +claims to cover. Paraphrase; never copy phrasing out of the description. A row lifted +from the description tests string matching, not activation. Vary the vocabulary and +include at least one oblique row where the user describes their *problem* rather than +the operation the skill performs. + +**Distractor rows** — adjacent requests the skill should *not* claim, especially ones +that share vocabulary with the description. These are what make precision meaningful. + +**Sibling-owned rows** *(optional)* — requests that legitimately belong to a **named +other skill in the same repository**, with `expected_skill` set to that sibling. In a +multi-skill repository, misrouting between two adjacent skills is the common failure, and +a plain distractor only shows *that* a misfire happened, not *where it went*. These rows +say where. + +Add them when two skills have overlapping subject matter and you want to know which one +wins. They cost extra rows, and **every row is a full agent run** — so treat them as a +targeted follow-up, not a default. + +**Never name the skill in a prompt.** That tests obedience, not activation: + +- Bad: "Use the pdf-forms skill to fill in this application." +- Good: "I need to fill in the fields on this application PDF and send it back." + +This rule is unaffected by sibling-owned rows: `expected_skill` is a **label** in the +dataset, read by the criterion and never shown to the agent. The row's `prompt` still must +not name any skill, the sibling included. + +**Sizing.** Minimum 3 positive + 3 distractor. Aim for **8–12 of each** for a signal +you can act on — recall over 3 rows moves in 33-point jumps, which is too coarse to +tell a real regression from noise. The shipped template holds 6 rows because that is +the illustrative minimum, not a target. Any sibling-owned rows are **on top** of that: +8–12 positives plus 8–12 distractors is already 16–24 runs, so state the resulting total +before writing the suite. + +**Refuse to generate a suite with no distractor rows.** With no negatives, precision +is 1.0 by definition and half the result is meaningless. Say why and ask for the +adjacent cases instead. + +## Step 4 — Write the suite + +Copy the two template files into the user's task directory (`tasks/` if it exists, +otherwise ask): + +- `${CLAUDE_PLUGIN_ROOT}/reference/templates/activation.yaml` +- `${CLAUDE_PLUGIN_ROOT}/reference/templates/activation-rows.jsonl` + +Then substitute, keeping the JSONL beside the YAML (`dataset.paths` entries resolve +relative to the task file): + +- `task_id` → `<skill-name>-activation` +- `skill_name` → the **bare** skill name +- each positive row's `expected_skill` → the same bare name; distractor rows keep `""`; + a sibling-owned row's `expected_skill` → that **sibling's** bare name +- every row's `prompt` → the requests designed in step 3, one JSON object per line + +**Then make the skill reachable, which is the step that decides whether the suite measures +anything.** The task runs in a fresh sandbox that contains none of the user's files, so the +agent is offered no skills unless the task says where they live. That is the `agent.plugins` +block in the template: `path` is the directory **containing** the skill's own directory — +for `.claude/skills/pdf-forms/SKILL.md` that is `.claude/skills`. Tell the user to export it +before running, and to use the same variable in CI: + +```bash +export SKILL_SOURCE_PATH="$(pwd)/.claude/skills" +``` + +Keep it an environment variable rather than baking an absolute path into the YAML — the +suite is committed and re-run on other machines. If the variable is unset the skill is simply +absent, every positive row scores 0, and the result is indistinguishable from a skill that +never triggers, so confirm it is set before reporting any low-recall finding. + +`skill_name` must be the bare name even when the skill comes from a plugin and is +invoked as `plugin:skill` — the checker strips the namespace before comparing. A +namespaced value here silently scores zero recall on every row, which reads exactly +like a broken skill. + +For criterion fields beyond this template, read +`${CLAUDE_PLUGIN_ROOT}/reference/criteria.md`. + +## Step 5 — Validate before spending anything + +`coder-eval plan <path-to-activation.yaml>` must exit 0. It is a schema check only — +it does not read the dataset file — so also confirm the JSONL sits next to the YAML +and has one object per line. + +## Step 6 — Run + +Every row is a full agent run: **N rows means N runs and real token cost**. State the +row count and the agent/model that will be used, then ask before starting. + +```bash +coder-eval run <path-to-activation.yaml> +``` + +The criterion is agent-agnostic — it detects Claude engaging the skill via the `Skill` +tool, and any agent without that tool (Codex, for instance) by reading the skill's +files off disk — so the same suite works whichever agent the task resolves to. + +## Step 7 — Report and interpret + +Present recall, precision, F1 and the confusion matrix, then say what they mean: + +- **Low recall** (misses rows it should have caught): **rule out truncation and listing + eviction before concluding the description under-claims.** Both produce a low-recall + result indistinguishable from bad wording, and both are cheap to check: `/doctor` + estimates the listing's context cost and its biggest contributors, and the **Skills row + in `/context`** reports the listing size *after* the budget is applied — that is what the + model actually received. Only once the description is demonstrably *in* the listing and + inside the per-skill cutoff is the wording the culprit: it does not name the situations, + file types, or phrasings that should trigger it. +- **Low precision** (fires on distractors): the description over-claims and is + stealing adjacent requests. Narrow it, and say explicitly what the skill is *not* + for. +- **Misfires concentrated on one sibling** (with sibling-owned rows): that is a boundary + dispute between two descriptions, not one vague description. Fixing the skill under test + alone tends to move the failure rather than remove it — say explicitly what **each** of + the two skills is not for, and re-run. +- **Both high**: report the numbers and the row count, and note that a small suite + says little — offer to widen it. + +Point at the frontmatter `description` as the thing to edit, quote the specific rows +that failed as evidence, and offer to re-run after the edit so the change is measured +rather than assumed.
