+## The `agents` Field: DO NOT ADD
 
-### Agents MUST use explicit file paths
+> WARNING: **CRITICAL:** Do NOT add an `"agents"` field to `plugin.json`. The Claude Code plugin validator rejects it entirely.
 
-The validator **does not accept directory paths for `agents`**.
+### Why This Matters
 
-Even the following will fail:
+The `agents` field is not part of the Claude Code plugin manifest schema. Any form of it -- string path, array of paths, or array of directories -- causes a validation error:
 
-```json
-{
-  "agents": ["./agents/"]
-}
+```
+agents: Invalid input
 ```
 
-Instead, you must enumerate agent files explicitly:
+Agent `.md` files under `agents/` are discovered automatically by convention (similar to hooks). They do not need to be declared in the manifest.
 
-```json
-{
-  "agents": [
-    "./agents/planner.md",
-    "./agents/architect.md",
-    "./agents/code-reviewer.md"
-  ]
-}
-```
+### History
 
-This is the most common source of validation errors.
+Previously this repo listed agents explicitly in `plugin.json` as an array of file paths. This passed the repo's own schema but failed Claude Code's actual validator, which does not recognize the field. Removed in #1459.

 ### Plugin Manifest Gotchas
 
-If you plan to edit `.claude-plugin/plugin.json`, be aware that the Claude plugin validator enforces several **undocumented but strict constraints** that can cause installs to fail with vague errors (for example, `agents: Invalid input`). In particular, component fields must be arrays, `agents` must use explicit file paths rather than directories, and a `version` field is required for reliable validation and installation.
+If you plan to edit `.claude-plugin/plugin.json`, be aware that the Claude plugin validator enforces several **undocumented but strict constraints** that can cause installs to fail with vague errors (for example, `agents: Invalid input`). In particular, component fields must be arrays, `agents` is not a supported manifest field and must not be included in plugin.json, and a `version` field is required for reliable validation and installation.
 
 These constraints are not obvious from public examples and have caused repeated installation failures in the past. They are documented in detail in `.claude-plugin/PLUGIN_SCHEMA_NOTES.md`, which should be reviewed before making any changes to the plugin manifest.

 # Changelog
 
+## 2.0.0-rc.1 - 2026-04-28
+
+### Highlights
+
+- Adds the public ECC 2.0 release-candidate surface for the Hermes operator story.
+- Documents ECC as the reusable cross-harness substrate across Claude Code, Codex, Cursor, OpenCode, and Gemini.
+- Adds a sanitized Hermes import skill surface instead of publishing private operator state.
+
+### Release Surface
+
+- Updated package, plugin, marketplace, OpenCode, agent, and README metadata to `2.0.0-rc.1`.
+- Added `docs/releases/2.0.0-rc.1/` with release notes, social drafts, launch checklist, handoff notes, and demo prompts.
+- Added `docs/architecture/cross-harness.md` and regression coverage for the ECC/Hermes boundary.
+- Kept `ecc2/` versioning independent for now; it remains an alpha control-plane scaffold unless release engineering decides otherwise.
+
+### Notes
+
+- This is a release candidate, not a GA claim for the full ECC 2.0 control-plane roadmap.
+- Prerelease npm publishing should use the `next` dist-tag unless release engineering explicitly chooses otherwise.

+# Cross-Harness Architecture
+
+ECC is the reusable workflow layer. Harnesses are execution surfaces.
+
+The goal is to keep the durable parts of agentic work in one repo:
+
+- skills
+- rules and instructions
+- hooks where the harness supports them
+- MCP configuration
+- install manifests
+- session and orchestration patterns
+
+Claude Code, Codex, OpenCode, Cursor, Gemini, and future harnesses should adapt those assets at the edge instead of requiring a new workflow model for every tool.
+
+## Portability Model
+
+| Surface | Shared Source | Harness Adapter | Current Status |
+|---------|---------------|-----------------|----------------|
+| Skills | `skills/*/SKILL.md` | Claude plugin, Codex plugin, `.agents/skills`, Cursor skill copies, OpenCode plugin/config | Supported with harness-specific packaging |
+| Rules and instructions | `rules/`, `AGENTS.md`, translated docs | Claude rules install, Codex `AGENTS.md`, Cursor rules, OpenCode instructions | Supported, but not identical across harnesses |
+| Hooks | `hooks/hooks.json`, `scripts/hooks/` | Claude native hooks, OpenCode plugin events, Cursor hook adapter | Hook-backed in Claude/OpenCode/Cursor; instruction-backed in Codex |
+| MCPs | `.mcp.json`, `mcp-configs/` | Native MCP config import per harness | Supported where the harness exposes MCP |
+| Commands | `commands/`, CLI scripts | Claude slash commands, compatibility shims, CLI entrypoints | Supported, but command semantics vary |
+| Sessions | `ecc2/`, session adapters, orchestration scripts | TUI/daemon, tmux/worktree orchestration, harness-specific runners | Alpha |
+
+## What Travels Unchanged
+
+`SKILL.md` is the most portable unit.
+
+A good ECC skill should:
+
+- use YAML frontmatter with `name`, `description`, and `origin`
+- describe when to use the skill
+- state required tools or connectors without embedding secrets
+- keep examples repo-relative or generic
+- avoid harness-only command assumptions unless the section is clearly labeled
+
+The same source skill can be installed into multiple harnesses because it is mostly instructions, constraints, and workflow shape.
+
+## What Gets Adapted
+
+Each harness has different loading and enforcement behavior:
+
+- Claude Code loads plugin assets and has native hook execution.
+- Codex reads `AGENTS.md`, plugin metadata, skills, and MCP config, but hook parity is instruction-driven.
+- OpenCode has a plugin/event system that can reuse ECC hook logic through an adapter layer.
+- Cursor uses its own rule and hook layout, so ECC maintains translated surfaces under `.cursor/`.
+- Gemini support is install/instruction oriented and should be treated as a compatibility surface, not as full hook parity.
+
+Adapters should stay thin. The shared behavior belongs in `skills/`, `rules/`, `hooks/`, `scripts/`, and `mcp-configs/`.
+
+## Hermes Boundary
+
+Hermes is not the public ECC runtime.
+
+Hermes is an operator shell that can consume ECC assets:
+
+- import selected ECC skills into a Hermes skills directory
+- use ECC MCP conventions for tool access
+- route chat, CLI, cron, and handoff workflows through reusable ECC patterns
+- distill repeated local operator work back into sanitized ECC skills
+
+The public repo should ship reusable patterns, not local Hermes state.
+
+Do ship:
+
+- sanitized setup docs
+- repo-relative demo prompts
+- general operator skills
+- examples that do not depend on private credentials
+
+Do not ship:
+
+- OAuth tokens or API keys
+- raw `~/.hermes` exports
+- personal workspace memory
+- private datasets
+- local-only automation packs that have not been reviewed
+
+## Today vs Later
+
+Supported today:
+
+- shared skill source in `skills/`
+- Claude Code plugin packaging
+- Codex plugin metadata and MCP reference config
+- OpenCode package/plugin surface
+- Cursor-adapted rules, hooks, and skills
+- `ecc2/` as an alpha Rust control plane
+
+Still maturing:
+
+- exact hook parity across all harnesses
+- automated skill sync into Hermes
+- release packaging for `ecc2/`
+- cross-harness session resume semantics
+- deeper memory and operator planning layers
+
+## Rule For New Work
+
+When adding a workflow, put the durable behavior in ECC first.
+
+Use harness-specific files only for:
+
+- loading the shared asset
+- adapting event shapes
+- mapping command names
+- handling platform limits
+
+If a workflow only works in one harness, document that boundary directly.

+# HOOK-FIX-20260421 Addendum — v2.1.116 argv 重複バグ
+
+朝セッションで commit 527c18b として修正済み。夜セッションで追加検証と、
+朝fix でカバーしきれない Claude Code 固有のバグを特定したので補遺を記録する。
+
+## 朝fixの形式
+
+```json
+"command": "C:/Users/sugig/.claude/skills/continuous-learning/hooks/observe-wrapper.sh pre"
+```
+
+`.sh` ファイルを直接 command にする形式。Git Bash が shebang 経由で実行する前提。
+
+## 夜 追加検証で判明したこと
+
+Node.js の `child_process.spawn` で `.sh` ファイルを直接実行すると Windows では
+**EFTYPE** で失敗する：
+
+```js
+spawn('C:/Users/sugig/.claude/skills/continuous-learning/hooks/observe-wrapper.sh', 
+      ['post'], {stdio:['pipe','pipe','pipe']});
+// → Error: spawn EFTYPE (errno -4028)
+```
+
+`shell:true` を付ければ cmd.exe 経由で実行できるが、Claude Code 側の実装
+依存のリスクが残る。
+
+## 夜 適用した追加 fix
+
+第1トークンを `bash`（PATH 解決）に変えた明示的な呼び出しに更新：
+
+```json
+{
+  "hooks": {
+    "PreToolUse": [{
+      "matcher": "*",
+      "hooks": [{
+        "type": "command",
+        "command": "bash \"C:/Users/sugig/.claude/skills/continuous-learning/hooks/observe-wrapper.sh\" pre"
+      }]
+    }],
+    "PostToolUse": [{
+      "matcher": "*",
+      "hooks": [{

+      }]
+    }]
+  }
+}
+```
+
+この形式は `~/.claude/hooks/hooks.json` 内の ECC 正規 observer 登録と
+同じパターンで、現実にエラーなく動作している実績あり。
+
+### Node spawn 検証
+
+```js
+spawn('bash "C:/Users/sugig/.claude/skills/continuous-learning/hooks/observe-wrapper.sh" post',
+      [], {shell:true});
+// exit=0 → observations.jsonl に正常追記
+```
+
+## Claude Code v2.1.116 の argv 重複バグ（詳細）
+
+朝fix docの「Defect 2」として `bash.exe: bash.exe: cannot execute binary file` を
+記録しているが、その根本メカニズムが特定できたので記す。
+
+### 再現
+
+```bash
+"C:\Program Files\Git\bin\bash.exe" "C:\Program Files\Git\bin\bash.exe"
+# stderr: "C:\Program Files\Git\bin\bash.exe: C:\Program Files\Git\bin\bash.exe: cannot execute binary file"
+# exit: 126
+```
+
+bash は argv[1] を script とみなし読み込もうとする。argv[1] が bash.exe 自身なら
+ELF/PE バイナリ検出で失敗 → exit 126。エラー文言は完全一致。
+
+### Claude Code 側の挙動
+
+hook command が `"C:\Program Files\Git\bin\bash.exe" "C:\Users\...\wrapper.sh"`
+のとき、v2.1.116 は**第1トークン（= bash.exe フルパス）を argv[0] と argv[1] の
+両方に渡す**と推定される。結果 bash は argv[1] = bash.exe を script として
+読み込もうとして 126 で落ちる。
+
+### 回避策
+

+3. `BAD:` `"C:\Program Files\Git\bin\bash.exe" "<path>"` — 1トークン目が quoted で空白込み
+
+## 結論
+
+朝fix（直接 .sh 指定）と夜fix（明示的 bash prefix）のどちらも argv 重複バグを
+踏まないが、**夜fixの方が Claude Code の実装依存が少ない**ため推奨。

+ただし朝fix commit 527c18b は既に docs/fixes/ に入っているため、この Addendum を

+# ECC Hook Fix — 2026-04-21
+
+## Summary
+
+Claude Code CLI v2.1.116 on Windows was failing all Bash tool hook invocations with:
+
+```
+PreToolUse:Bash hook error
+Failed with non-blocking status code:
+C:\Program Files\Git\bin\bash.exe: C:\Program Files\Git\bin\bash.exe:
+cannot execute binary file
+
+PostToolUse:Bash hook error  (同上)
+```
+
+Result: `observations.jsonl` stopped updating after `2026-04-20T23:03:38Z`
+(last entry was a `parse_error` from an earlier BOM-on-stdin issue).
+
+## Root Cause
+
+`C:\Users\sugig\.claude\settings.local.json` had two defects:
+
+### Defect 1 — UTF-8 BOM + CRLF line endings
+
+The file started with `EF BB BF` (UTF-8 BOM) and used `CRLF` line terminators.
+This is the PowerShell `ConvertTo-Json | Out-File` default behavior, and it is
+what `patch_settings_cl_v2_simple.ps1` leaves behind when it rewrites the file.
+
+```
+00000000: efbb bf7b 0d0a 2020 2020 2268 6f6f 6b73  ...{..    "hooks
+```
+
+### Defect 2 — Double-wrapped bash.exe invocation
+
+The command string explicitly re-invoked bash.exe:
+
+```json
+"command": "\"C:\\Program Files\\Git\\bin\\bash.exe\" \"C:\\Users\\sugig\\.claude\\skills\\continuous-learning\\hooks\\observe-wrapper.sh\""
+```
+
+When Claude Code spawns this on Windows, argument splitting does not preserve
+the quoted `"C:\Program Files\..."` token correctly. The embedded space in
+`Program Files` splits `argv[0]`, and `bash.exe` ends up being passed to
+itself as a script file, producing:
+
+```
+bash.exe: bash.exe: cannot execute binary file
+```
+
+### Prior working shape (for reference)
+
+Before `patch_settings_cl_v2_simple.ps1` ran, the command was simply:
+
+```json
+"command": "C:\\Users\\sugig\\.claude\\skills\\continuous-learning\\hooks\\observe.sh"
+```
+
+Claude Code on Windows detects `.sh` and invokes it via Git Bash itself — no
+manual `bash.exe` wrapping needed.
+
+## Fix
+
+`C:\Users\sugig\.claude\settings.local.json` rewritten as UTF-8 (no BOM), LF
+line endings, with the command pointing directly at the wrapper `.sh` and
+passing the hook phase as a plain argument:
+
+```json
+{
+  "hooks": {
+    "PreToolUse": [
+      {
+        "matcher": "*",
+        "hooks": [
+          {
+            "type": "command",
+            "command": "C:/Users/sugig/.claude/skills/continuous-learning/hooks/observe-wrapper.sh pre"
+          }
+        ]
+      }
+    ],
+    "PostToolUse": [
+      {
+        "matcher": "*",
+        "hooks": [
+          {
+            "type": "command",
+            "command": "C:/Users/sugig/.claude/skills/continuous-learning/hooks/observe-wrapper.sh post"
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+Side benefit: the `pre` / `post` argument is now routed to `observe.sh`'s
+`HOOK_PHASE` variable so events are correctly logged as `tool_start` vs
+`tool_complete` (previously everything was recorded as `tool_complete`).
+
+## Verification
+
+Direct invocation of the new command format, emulating both hook phases:
+
+```bash
+# PostToolUse path
+echo '{"tool_name":"Bash","tool_input":{"command":"pwd"},"session_id":"post-fix-verify-001","cwd":"...","hook_event_name":"PostToolUse"}' \
+  | "C:/Users/sugig/.claude/skills/continuous-learning/hooks/observe-wrapper.sh" post
+# exit=0
+
+# PreToolUse path
+echo '{"tool_name":"Bash","tool_input":{"command":"ls"},"session_id":"post-fix-verify-pre-001","cwd":"...","hook_event_name":"PreToolUse"}' \
+  | "C:/Users/sugig/.claude/skills/continuous-learning/hooks/observe-wrapper.sh" pre
+# exit=0
+```
+
+`observations.jsonl` gained:
+
+```
+{"timestamp":"2026-04-21T05:57:54Z","event":"tool_complete","tool":"Bash","session":"post-fix-verify-001",...}
+{"timestamp":"2026-04-21T05:57:55Z","event":"tool_start","tool":"Bash","session":"post-fix-verify-pre-001","input":"{\"command\":\"ls\"}",...}
+```
+
+Both phases now produce correctly typed events.
+
+**Note on live CLI verification:** settings changes take effect on the next
+`claude` CLI session launch. Restart the CLI and run a Bash tool call to
+confirm new rows appear in `observations.jsonl` from the actual CLI session.

+# install_hook_wrapper.ps1 argv-dup bug workaround (2026-04-22)
+
+## Summary
+
+`docs/fixes/install_hook_wrapper.ps1` is the PowerShell helper that copies
+`observe-wrapper.sh` into `~/.claude/skills/continuous-learning/hooks/` and
+rewrites `~/.claude/settings.local.json` so the observer hook points at it.
+
+The previous version produced a hook command of the form:
+
+```
+"C:\Program Files\Git\bin\bash.exe" "C:\Users\...\observe-wrapper.sh"
+```
+
+Under Claude Code v2.1.116 the first argv token is duplicated. When that token
+is a quoted Windows executable path, `bash.exe` is re-invoked with itself as
+its `$0`, which fails with `cannot execute binary file` (exit 126). PR #1524
+documents the root cause; this script is a companion that keeps the installer
+in sync with the fixed `settings.local.json` layout.
+
+## What the fix does
+
+- First token is now the PATH-resolved `bash` (no quoted `.exe` path), so the
+  argv-dup bug no longer passes a binary as a script.
+- The wrapper path is normalized to forward slashes before it is embedded in
+  the hook command, avoiding MSYS backslash handling surprises.
+- `PreToolUse` and `PostToolUse` receive distinct commands with explicit
+  `pre` / `post` positional arguments, matching the shape the wrapper expects.
+- The settings file is written with LF line endings so downstream JSON parsers
+  never see mixed CRLF/LF output from `ConvertTo-Json`.
+
+## Resulting command shape
+
+```
+bash "C:/Users/<you>/.claude/skills/continuous-learning/hooks/observe-wrapper.sh" pre
+bash "C:/Users/<you>/.claude/skills/continuous-learning/hooks/observe-wrapper.sh" post
+```
+
+## Usage
+
+```powershell
+# Place observe-wrapper.sh next to this script, then:
+pwsh -File docs/fixes/install_hook_wrapper.ps1
+```
+
+The script backs up `settings.local.json` to
+`settings.local.json.bak-<timestamp>` before writing.
+
+## PowerShell 5.1 compatibility
+
+`ConvertFrom-Json -AsHashtable` is PowerShell 7+ only. The script tries
+`-AsHashtable` first and falls back to a manual `PSCustomObject` →
+`Hashtable` conversion on Windows PowerShell 5.1. Both hook buckets
+(`PreToolUse`, `PostToolUse`) and their inner `hooks` arrays are
+materialized as `System.Collections.ArrayList` before serialization, so
+PS 5.1's `ConvertTo-Json` cannot collapse single-element arrays into
+bare objects. Verified by running `powershell -NoProfile -File
+docs/fixes/install_hook_wrapper.ps1` on a Windows 11 machine with only
+Windows PowerShell 5.1 installed (no `pwsh`).

+# patch_settings_cl_v2_simple.ps1 argv-dup bug workaround (2026-04-22)
+
+## Summary
+
+`docs/fixes/patch_settings_cl_v2_simple.ps1` is the minimal PowerShell
+helper that patches `~/.claude/settings.local.json` so the observer hook
+points at `observe-wrapper.sh`. It is the "simple" counterpart of
+`docs/fixes/install_hook_wrapper.ps1` (PR #1540): it never copies the
+wrapper script, it only rewrites the settings file.
+
+The previous version of this helper registered the raw `observe.sh` path
+as the hook command, shared a single command string across `PreToolUse`
+and `PostToolUse`, and relied on `ConvertTo-Json` defaults that can emit
+CRLF line endings. Under Claude Code v2.1.116 the first argv token is
+duplicated, so the wrapper needs to be invoked with a specific shape and
+the two hook phases need distinct entries.
+
+## What the fix does
+
+- First token is the PATH-resolved `bash` (no quoted `.exe` path), so the
+  argv-dup bug no longer passes a binary as a script. Matches PR #1524 and
+  PR #1540.
+- The wrapper path is normalized to forward slashes before it is embedded
+  in the hook command, avoiding MSYS backslash handling surprises.
+- `PreToolUse` and `PostToolUse` receive distinct commands with explicit
+  `pre` / `post` positional arguments.
+- The settings file is written UTF-8 (no BOM) with CRLF normalized to LF
+  so downstream JSON parsers never see mixed line endings.
+- Existing hooks (including legacy `observe.sh` entries and unrelated
+  third-party hooks) are preserved — the script only appends the new
+  wrapper entries when they are not already registered.
+- Idempotent on re-runs: a second invocation recognizes the canonical
+  command strings and logs `[SKIP]` instead of duplicating entries.
+
+## Resulting command shape
+
+```
+bash "C:/Users/<you>/.claude/skills/continuous-learning/hooks/observe-wrapper.sh" pre
+bash "C:/Users/<you>/.claude/skills/continuous-learning/hooks/observe-wrapper.sh" post
+```
+
+## Usage
+
+```powershell
+pwsh -File docs/fixes/patch_settings_cl_v2_simple.ps1
+# Windows PowerShell 5.1 is also supported:
+powershell -NoProfile -ExecutionPolicy Bypass -File docs/fixes/patch_settings_cl_v2_simple.ps1
+```
+
+The script backs up the existing settings file to
+`settings.local.json.bak-<timestamp>` before writing.
+
+## PowerShell 5.1 compatibility
+
+`ConvertFrom-Json -AsHashtable` is PowerShell 7+ only. The script tries
+`-AsHashtable` first and falls back to a manual `PSCustomObject` →
+`Hashtable` conversion on Windows PowerShell 5.1. Both hook buckets
+(`PreToolUse`, `PostToolUse`) and their inner `hooks` arrays are
+materialized as `System.Collections.ArrayList` before serialization, so
+PS 5.1's `ConvertTo-Json` cannot collapse single-element arrays into bare
+objects.
+
+## Verified cases (dry-run)
+
+1. Fresh install — no existing settings → creates canonical file.
+2. Idempotent re-run — existing canonical file → `[SKIP]` both phases,
+   file contents unchanged apart from the pre-write backup.
+3. Legacy `observe.sh` present → preserves the legacy entries and
+   appends the new `observe-wrapper.sh` entries alongside them.
+
+All three cases produce LF-only output and match the shape registered by
+PR #1524's manual fix to `settings.local.json`.
