No agent definition referenced that rule as a persistence mode + and neither recovery ladder carried a rung for it: `skills/explore/reference/dispatch.md` and + `skills/research/context/dispatch.md` had rungs for a bad envelope, a live agent to resume, and a + refused resume, and none for *the worker could not write*. Following the rule anyway guaranteed a + halt — an empty slice holding only the parent's pre-dispatch baseline is exactly what + `check-dispatch-artifact.sh` exits 1 on, and both `SKILL.md` files declared any non-zero exit to + halt the workflow. Two documents in one plugin prescribed opposite outcomes for the same run, and + the correct one was the unreachable one. + + Compounding it, no payload value could say what had happened. `status` was `complete | truncated` + and `truncated` is the turn-budget stop whose ladder consequence is *discard the partial slice*; + `complete` requires an `artifact:` pointer the run had no file to name. Both available values + misdescribed a run that finished its work and could not save it, and the only honest one routed + the parent to throw the work away. Observed consequence: a parent reinvented the by-value rule ad + hoc in a resume message, because the rule the plugin already owned could not be reached from the + failure it was written for. + + **`persistence: written | by-value` is now its own payload axis** on both agents, deliberately + separate from `status` and from `coverage` — `truncated` keeps meaning the budget stop, so the + discard rung stays correct, and `coverage` stays a statement about exploration and the corpus + ledger rather than about the disk. On the by-value path the agent returns its index, sidecars and + ledger as verbatim bodies after the YAML block, `artifact:` names the path the parent must write + to (a destination, not a claim that a file exists), and both ladders gained the matching rung + ahead of the resume rung: **the parent writes the slice from the payload, then re-runs the same + gate.** + + **The exception is to the halt, not to the gate**, and both `SKILL.md` files now say so in those + terms. The workflow proceeds only on a subsequent exit 0 — for research, from both the artifact + gate and the coverage-ledger gate. `persistence: by-value` routes the parent and grades nothing; + a by-value payload that returns *findings* instead of artifact bodies is a failed dispatch, not a + fallback, because a claim the gate is invited to accept on the agent's word is the same laundering + the source-tier discipline refuses everywhere else. A by-value slice earns its exit 0 from the + identical command, freshness check included: the parent writes after its own pre-dispatch `touch`. + + This also closes the seam where exit 1 read identically for "never ran" and "ran well, could not + persist". The script is right to grade disk state and nothing else; the branch belongs one level + up, in the ladder, where gate step 1 has already put the payload in the parent's hands. + + **Three conditions bind the parent's write, because the recovery path must not become a hole in + the rules it recovers into.** The by-value rung is the only place in this contract where a + filename the *worker* produced becomes a write the *parent* performs, and the parent holds wider + write permission than the sandboxed worker — a researcher in particular spends its whole run + ingesting untrusted third-party pages. So: filenames are checked **before** anything reaches disk + and only the contract's own names are accepted (`EXPLORE.md` / `EXPLORE-
.md`, + `RESEARCH.md` / `RESEARCH-
.md` / `research-checklist.md`), as bare filenames; a directory + separator, a `..` segment or a leading `/` makes the payload a failed dispatch rather than a name + to sanitize. The explorer's **collision rule still applies** — a slice root already holding an + unrelated `EXPLORE.md` gets a parent-assigned sub-slice here too, because overwriting the index + that rule protects would be a silent, unrecoverable loss arriving through the recovery path. And + the research side's **unbounded-corpus rule is unchanged** — a run that recorded the corpus as + unbounded wrote no ledger and owes none here, so the coverage gate is re-run only when a ledger + was owed; running it against a file nobody was supposed to write exits 2, a FAIL, and would halt a + complete run on a check that never applied to it. + +- **`agents/researcher.md` described a tool grant it never made.** The file declared no `tools:` key + and no `disallowedTools:` key, so it inherited every tool available to a subagent — while its own + "Tool honesty" section asserted "`Edit` is absent from your tool list" and "`Agent` is listed." + Both sentences are false there. The paragraph is a verbatim copy from `agents/explorer.md`, where + the `tools:` allowlist at line 4 makes both of them true; it was carried into a file whose + frontmatter inverts them. Inheritance was not only derivable but observed — the agent's own + transcript shows it calling `ToolSearch` and `WebFetch`, neither of which appears in the + explorer's allowlist. + + The harm is not tidiness. This is an unattended `maxTurns: 40` worker whose entire write boundary + is instruction-held, and the false inventory — understating the pool by roughly a dozen tools + including a second shell and the whole session MCP set — is the calibration input for that + boundary. Least-privilege understatement is the dangerous polarity. + + The section now states what is true: no allowlist is declared, the pool is inherited, `Edit` and + `PowerShell` are held, `Agent` is inherited and conditionally filtered at the depth limit, the MCP + pool is held, and the memory-tier boundary holds by instruction and by nothing else. **No `tools:` + allowlist was added** — an allowlist removes every MCP tool, and the skill's third mandatory + discipline requires doc-MCP servers in the tool spread, so the allowlist would break the discipline + it was meant to protect. A narrow `disallowedTools:` denylist is the instrument instead. + + Three decisions are now written down rather than left accidental. **`NotebookEdit` is denied** — + nothing in the contract writes notebooks. **`Edit` is kept, deliberately**: `research-checklist.md` + rows go `[ ]` → `[x]` as phases proceed, and denying `Edit` would force a full-file rewrite of the + coverage ledger at every phase boundary. **`EnterWorktree`/`ExitWorktree` are denied and + `isolation: worktree` is not set on either agent**, because these artifacts are graded off disk by + the parent, in the parent's checkout, against a slice path the parent resolved before dispatch — + work written into an isolated copy of the repository lands where that gate never looks, and the run + would read as having produced nothing. Isolation and a disk-graded handoff are incompatible by + construction; this plugin chose the handoff. The explorer/researcher asymmetry is now stated in + both files as the deliberate thing it is. + + One thing the fix does **not** claim: it does not make the write boundary enforceable. You cannot + deny "Bash writing a file" without denying `Bash`, which the research discipline needs. Both agents + instead gain an explicit instruction that a refused `Write` is an answer rather than an obstacle — + do not route the same write through `Bash` to get around it. That is grounded in the transcript + asymmetry it was observed as (three `Write` calls refused while a Bash-mediated write succeeded to + the same directory tree), not in any documented rule about which guard covers which tool. + +- **Nothing restated the input, so a corrupted scope or topic passed every gate.** Every refusal + mechanism in the plugin was a presence test — preload token present or `MISSING`, envelope field + present or absent, index on disk or not, ledger rows marked or not, `artifact:` pointer present or + not — so none of them could fire on an input that arrived present and wrong. Observed 2026-08-10: + an argument naming *another* plugin's `${CLAUDE_PLUGIN_DATA}` directory reached a dispatched agent + rewritten to this plugin's own path. The agent was asked a factually wrong question and answered + it correctly, which is the most expensive shape of wrong available. + + Both agents now echo the envelope back — `scope_as_received:` / `topic_as_received:`, quoted + verbatim, explicitly not paraphrased or normalized — and both acceptance gates compare it against + the envelope the parent wrote. A mismatch is a failed dispatch even when the artifact is complete + and every mechanical check exits 0. A payload lacking the field is an out-of-date agent definition, + not a pass. + + The accompanying caveat in `skills/explore`, `skills/research` and `skills/research-deep` is + written as an observation rather than a mechanism, on purpose. What is documented (both pages + fetched 2026-08-11) is that skill and agent content is a substitution site for the three + `${CLAUDE_*}` path placeholders "anywhere the placeholder appears", and that no escape exists for + them — "A backslash before any other `$` is left unchanged" covers `$ARGUMENTS` and declared + argument names, not these. What is documented nowhere is whether argument-supplied text is itself + scanned for those placeholders. The caveat therefore states the observation, the two documented + facts, and the gap, and **carries an unconditional 2027-02-11 expiry** so the claim cannot go stale + invisibly. The echo-back is the part that works under either reading. + + The caveat also states its own boundary, because two nearby claims read as if they were about one + thing. This is about placeholder-shaped text a **caller** supplies on the inline path or in a + dispatch prompt. It is a different question from what the adjacent paragraph says about a + `$ARGUMENTS` placeholder the plugin's **own body** carries on the preload path, and it is evidence + for neither side of it. That older claim is untouched here and is tracked separately. + +### Added + +- `plugins/discovery/agents/tool-honesty.test.sh` — a contract test over this plugin's own agent + definitions, locking the class of drift the second entry describes rather than the one instance of + it: prose claiming a tool is absent from (or present in) a tool list must be backed by a `tools:` + key that actually omits (or lists) it, every agent must declare its posture in frontmatter rather + than leaving the prose as the only inventory, neither agent may set `isolation:`, and both payload + contracts must carry the `persistence:` and echo-back fields. Scoped to this plugin's agents on + purpose — a repo-wide sweep would fail this plugin's test on another plugin's drift. + +- `scripts/check-dispatch-artifact.test.sh` gains the by-value pair: a slice holding only the + pre-dispatch baseline exits 1, and the same slice exits 0 once the parent writes it from the + payload, with freshness and pointer checks both passing. The pair is the point — the first half + proves the exception answers a failure the gate really produces, the second proves the recovery + routes *through* the gate rather than around it. + +- Eval cases on both skills covering the outcomes the new axis has to keep apart: a by-value + recovery that must be written and re-graded rather than discarded, a by-value payload carrying + findings instead of artifact bodies (a failed dispatch, not a fallback), an echo-back mismatch + that fails a dispatch whose artifact is otherwise perfect, a by-value payload naming a file + outside the contract (rejected before anything is written), an explore-side recovery into a slice + root already holding an unrelated index, and a research-side recovery of an unbounded corpus, + which owes no ledger and must not be graded against one. + ## [0.13.1] ### Fixed diff --git a/plugins/discovery/agents/explorer.md b/plugins/discovery/agents/explorer.md index 53141b2716..dfc5b74d55 100644 --- a/plugins/discovery/agents/explorer.md +++ b/plugins/discovery/agents/explorer.md @@ -72,10 +72,26 @@ mutating Bash — no writes, moves, deletes, or installs, and no git-state chang exactly two permitted destinations: the artifact files inside the memory-slice path named in your dispatch prompt, and the memory root's self-ignoring `.gitignore` guard when it is absent. -`Edit` is absent from your tool list.

Each writes the normal `RESEARCH.md` index, its sidecars, and its own `research-checklist.md` inside that sub-slice; those filenames are fixed, so N agents pointed at one slice root would overwrite one another's index and ledger rather than producing separable artifacts. **This session owns each topic's post-dispatch boundary — synthesis is the last step, not the only one.** Close "The post-dispatch boundary" below for **each** topic, then synthesize the slice-root `RESEARCH.md` from the per-topic indexes. Skipping it produces the worst available artifact: a root `RESEARCH.md` presenting claims as gate-passed when the rows that matter were never graded by anyone.
