Dispatches scoped-write explorer subagents in parallel for general research and exploration of any codebase, topic, or domain. The operator passes --path (output directory), --agents (parallel count), and --prompt (research question). The parent scouts the territory first to divide work, dispatches N explorer subagents that each write one analysis file at <path>/analysis/NN_analysis_<slug>.md following a seven-section schema, then synthesizes <path>/analysis/summary.md. The skill self-contains the explorer subagent definition and prompts the operator to install it at .claude/agents/explorer.md when absent. Use when running parallel multi-area research that must produce written artifacts. Do not use for competitor-only research already covered by cy-research-competitors, single-file lookups answerable by Explore, or edits to existing code.

Generic parallel-research workflow. Use when a question requires deep reads across multiple distinct areas and the operator needs written artifacts (not chat output). The skill dispatches explorer subagents in parallel; each writes one analysis file. The parent then synthesizes a final summary.
The skill is self-contained. It ships two explorer subagent definitions side by side so the same skill works on both major harnesses:
Claude Code: assets/explorer-agent.md → installed to .claude/agents/explorer.md (Markdown with YAML frontmatter).
OpenAI Codex CLI: assets/explorer-agent.toml → installed to .codex/agents/explorer.toml (single TOML document with sandbox_mode = "workspace-write" and the scoped-write contract carried in developer_instructions).
The parent verifies installation for the active harness before every dispatch.

Reference Index
references/dispatch-rules.md — the scoped-write contract: what the subagent may write, may read, may run; tool allow/forbid lists; parent responsibilities; parallelism cap; failure handling. Must be embedded verbatim in every subagent prompt.
references/checklist.md — seven-section output validation checklist (installation, inputs, scout, dispatch, files, schema, summary). Run before authoring summary.md.
assets/analysis-template.md — the canonical seven-section schema every subagent fills (Overview, Mechanisms/Patterns, Relevant Sources, Transferable Patterns, Risks/Mismatches, Open Questions, Evidence) plus a Scope header.
assets/explorer-agent.md / assets/explorer-agent.toml — the bundled subagent definitions for Claude Code and Codex CLI. Installed by scripts/install-explorer.sh.
scripts/install-explorer.sh — bootstrap helper. Writes the explorer definition to the active harness's expected path. Refuses to overwrite.
Bundled Path Rule
Resolve every bundled helper relative to the directory that holds this SKILL.md. When a command appears below as scripts/<name>, treat the actual invocation as <agent-exploration-dir>/scripts/<name> — expand <agent-exploration-dir> to the absolute skill directory before running.
Required Inputs
--path <dir> (required): Output directory. Analysis files are written under <path>/analysis/. Any project-relative or absolute directory works (for example docs/research/<topic>/, tasks/<slug>/, or a path outside the repo). The skill is not tied to any specific project layout.
--agents <num> (optional, default 3, hard cap 8): Number of explorer subagents to dispatch in parallel. Caps prevent runaway dispatch when the prompt is vague.
--prompt <text> (required): The research question. Quoted multi-line strings are supported. If omitted, the parent asks the operator before continuing.
If --path or --prompt is missing, the parent asks the operator a single clarification before continuing. Never invent defaults for either.
File numbering is zero-padded to two digits (01, 02, …, 08).
Each slug is a short kebab-case identifier the parent assigns during the scout (Step 3), reflecting that slice's focus.
summary.md is parent-authored synthesis, not a subagent output.
Procedures
Step 1: Verify the explorer subagent is installed
Detect the active harness:
If the runtime is Claude Code (project contains .claude/ or CLAUDE.md), the expected install path is .claude/agents/explorer.md.
If the runtime is Codex CLI (project contains .codex/ or AGENTS.md), the expected install path is .codex/agents/explorer.toml.
If both are present, both targets must be installed (or the operator must opt out per-target).
For each expected target, check whether the file exists.
If every expected target is present, proceed to Step 2.
If any expected target is missing, ask the operator a single question naming the missing targets: e.g. "The explorer subagent is not installed for Claude Code (.claude/agents/explorer.md) and Codex CLI (.codex/agents/explorer.toml). Install both now? [yes/no/claude-only/codex-only]". Do not proceed silently.
On any "yes" answer, run the bundled bootstrap helper (scripts/install-explorer.sh — bootstrap helper, writes one or two files) with the matching --target:
<agent-exploration-dir>/scripts/install-explorer.sh --target both (default)
<agent-exploration-dir>/scripts/install-explorer.sh --target claude
<agent-exploration-dir>/scripts/install-explorer.sh --target codex
Add --user to install into $HOME instead of the nearest project root. The helper refuses to overwrite existing files and prints OK / SKIP per target.
On "no", abort the dispatch with a one-line message. Do not dispatch the explorer subagent before installation completes — the dispatch will fail with "agent not found".
After installation, re-check that the expected target file(s) exist before continuing.
Step 2: Resolve inputs
Parse --path, --agents, --prompt from the invocation. If --path or --prompt is missing, ask the operator and stop.
Default --agents to 3 when omitted. Reject values below 1 or above 8 — ask the operator to choose a value in range.
Resolve --path to an absolute path. If the directory does not exist, ask the operator whether to create it before continuing.
Create <path>/analysis/ if absent. The subagents refuse to write into a missing directory.
Step 3: Parent-led initial scout (MANDATORY — do not skip)
The scout is the load-bearing step that prevents wasted parallel dispatch. The parent must do this work itself before any subagent is launched.
Perform a brief read-only exploration of the problem space using Glob, Grep, and targeted Read calls. The scout's job is to learn enough about the territory to divide it well — not to produce analysis content. Cap the scout at 8–15 tool calls; deep reading belongs to the subagents.
From the scout, identify exactly --agents distinct slices that are:
Non-overlapping — two slices should not require reading the same primary files for the same purpose.
Independently answerable — a slice's analysis must not depend on another slice's output.
Aligned with the operator's --prompt — every slice serves the original research question.
For each slice, assign:
A two-digit ordinal (01..08).
A short kebab-case slug (≤ 4 words) reflecting that slice's focus (e.g. state-machine, event-bus, auth-boundaries).
A focused per-slice prompt that names the slice question, the primary source paths/URLs to read, and any cross-references the subagent should use.
Briefly tell the operator the slice list (one line per slice: NN – slug – focus) before dispatching. Do not ask for approval unless the slices look thin or overlap; just announce and proceed.
If the scout reveals that fewer than --agents non-overlapping slices exist, reduce the dispatch count and tell the operator. Do not pad slices to hit the requested count.
Step 4: Dispatch explorer subagents in parallel
Gist tripwires — the contract items the parent must enforce in every prompt:
The prompt names three things: slice scope, slug+ordinal, exact target file path. If any is missing, the subagent must refuse and ask back.
The subagent gets exactly one Write — at the named target path — and nothing else. No Edit, no git/make/package managers, no writes outside <path>/analysis/.
All subagents dispatch in the same parallel batch with subagent_type: explorer. Wait for the full set before continuing.
STOP. Read references/dispatch-rules.md in full before composing any subagent prompt. That file contains the complete scoped-write contract, tool allow/forbid lists, parent responsibilities, and failure handling. The bullets above are tripwires, not the contract — the contract must be embedded verbatim in every subagent prompt.
STOP. Read assets/analysis-template.md in full before composing any subagent prompt. That file is the canonical seven-section schema every subagent fills. The schema must be embedded in the prompt; do not paraphrase it.
Compose one explorer subagent prompt per slice. Every prompt MUST include:
The operator's original --prompt verbatim, prefixed by a short orientation line.
The slice's focused question and the primary sources to read.
The exact target path: <path>/analysis/NN_analysis_<slug>.md (absolute path).
references/dispatch-rules.md content embedded verbatim (copy-paste, do not paraphrase).
The seven-section schema from assets/analysis-template.md.
Dispatch all subagents in the same Agent batch with subagent_type: explorer on every call. Wait for every subagent to return before continuing — a partial set is unacceptable.
Step 5: Verify outputs
Gist tripwires — the floor items that catch most failures:
Exactly N files at the expected NN_analysis_<slug>.md paths under <path>/analysis/.
All seven schema sections present in each file; no empty sections without a gap-note + Open Question.
At least one cited source per file sample-checked (Read for local paths, well-formedness for URLs).
STOP. Read references/checklist.md in full before declaring outputs verified. That file is the seven-section output validation checklist (installation, inputs, scout, dispatch, files, schema, summary). Every item must pass; failing items trigger a re-dispatch of the offending slice. The three bullets above are tripwires, not the contract.
If a section is empty, a file is missing, a cited path is fake, or the schema is incomplete, re-dispatch the offending subagent with the schema embedded and a request to fill the gap. The parent never authors the missing analysis content — the subagent owns the write.
Step 6: Synthesize summary.md
Read every <path>/analysis/NN_analysis_<slug>.md in full.
Author <path>/analysis/summary.md with these sections:
Research Question — the operator's --prompt, verbatim.
Slice Map — table mapping each NN – slug to its slice question and one-line finding.
Convergences — patterns or risks that appear in two or more analyses, with cross-citations to the slice files.
Divergences — places where slices disagree or where one slice surfaces a finding the others miss.
Risks & Open Questions — consolidated, deduplicated list pulled from each analysis's Open Questions and Risks/Mismatches sections.
Recommended Next Steps — short, actionable list. Each step cites the slice file(s) that support it.
Index — bullet list of <path>/analysis/NN_analysis_<slug>.md paths so a future reader can drill in.
summary.md is parent-authored. Do not dispatch a subagent for this step.
When Not To Use
Single-file lookups ("where is X defined?", "what does function Y return?"): use Explore or direct Grep/Read. This skill is overkill.
Edits to existing code: explorer is scoped-write — it can only create new analysis files, not modify anything else.
Tightly scoped competitor / reference-repo research in projects that already ship a more specialized variant (for example a project-local skill that mirrors a fixed competitor catalog). Use that variant when it exists; use this skill as the generic fallback.
Error Handling
Operational tripwires only — the full failure taxonomy lives in references/dispatch-rules.md (Failure Handling) and references/checklist.md.
Active-harness target missing and operator declines install: abort the dispatch with a one-line message. Do not attempt to inline-define the subagent in the dispatch prompt.
--path directory cannot be created: stop and report the filesystem error. Do not fall back to the current working directory silently.
--agents out of range: ask the operator for an in-range value. Do not auto-clamp.
Scout cannot find --agents non-overlapping slices: reduce the dispatch count, inform the operator, and proceed with the smaller set.
Contract violation, schema-incomplete analysis, fabricated evidence, or ambiguous-prompt refusal:STOP. Re-read references/dispatch-rules.md in full before re-dispatching. The parent never authors the missing content; the subagent owns the write.
Network/disk error during dispatch: fail the round entirely. Do not produce a half-set of analyses. Re-dispatch after the error is resolved.
