feat(cross-llm): Group I + III skill rewrites for cross-host portability

[intel352]

Summary

Rewrites Group I (using-superpowers, writing-skills) and Group III (subagent-driven-development, executing-plans) skills to replace Claude-Code-specific tool names and model brand names with host-neutral equivalents. Also upgrades alignment-check and pr-monitoring (Group II) to the full procedure-restructure approach, superseding the partial fix from PR-B.

Skills changed

Group I:

Skill	Change
using-superpowers	Replace TodoWrite/EnterPlanMode in dot-graph node labels with host-neutral text
writing-skills/SKILL.md	Wrap TodoWrite checklist instruction in <host: claude-code>
writing-skills/anthropic-best-practices.md	Replace Haiku/Sonnet/Opus brand names with fast/balanced/frontier tier roles; wrap Claude-specific examples in <host: claude-code>
writing-skills/persuasion-principles.md	Wrap TodoWrite references in <host: claude-code>

Group II (upgraded from PR-B partial fix):

Skill	Change
alignment-check	Move full Comparison Procedure (forward/reverse trace, report format) to host-neutral prose; <host: claude-code> contains only the slim Agent tool invocation; add <host: codex, opencode, cursor> block for inline execution
pr-monitoring	Host-neutral intro describes what the agent does; detailed Monitor Loop (steps 1–4, bash commands) stays inside <host: claude-code> Agent prompt; add <host: codex, opencode, cursor> block covering checks + comments + CHANGES_REQUESTED reviews

Group III:

Skill	Change
subagent-driven-development/SKILL.md	Wrap Agent Teams setup (TeamCreate, SendMessage, TaskUpdate) in <host: claude-code>; add <host: codex> sequential-mode block; Opus/Sonnet → frontier/balanced tier; rename "Legacy Mode" → "Sequential Mode"
spec-reviewer-prompt.md	Move <host: claude-code> block before fenced template; wrap TaskUpdate + DM references in host-conditioned blocks
code-quality-reviewer-prompt.md	Move <host: claude-code> block before fenced template; wrap TaskUpdate + DM references; clarify "orchestrator (team-lead on Claude Code)" terminology
executing-plans	Wrap TodoWrite in <host: claude-code>; add <host: codex, opencode, cursor> checklist fallback; host-neutral step uses generic task-system language

Verification

The modified files pass tests/skill-content-grep.sh. Pre-existing violations in other skills are outside this PR's scope.

Part of

Cross-LLM portability series: PR-A (infra) → PR-B (Group II) → PR-C (Group I+III) → PR-D (docs) → PR-E (coverage table)

Pull request overview

This PR updates several skills in Groups I and III to improve cross-host portability by replacing Claude-Code-specific tool/model references with host-neutral phrasing and/or <host: ...> conditioned sections.

Changes:

• Replaced Claude tool/model brand mentions (e.g., TodoWrite, Haiku/Sonnet/Opus) with host-neutral text and tier roles (fast / balanced / frontier).
• Added <host: claude-code> blocks to isolate Claude-specific instructions/examples while keeping generic guidance available to all hosts.
• Updated subagent-driven-development to clarify execution modes and add Codex-specific sequential-mode notes.

[Copilot]

As in the spec reviewer template, embedding <host: claude-code> markers inside the fenced “Task tool” snippet makes the template harder to copy/paste as a single valid block. Consider moving host-conditioned guidance outside the fence or providing separate fenced variants per host.

[Copilot]

The top-level overview now describes this skill as executing plans using a role-based subagent team, but the skill still includes (and now emphasizes) a Sequential Mode fallback. Consider rewording this overview sentence to be host-neutral (e.g., mention both team-based and sequential execution) so it stays accurate across hosts.

Suggested change

	Execute a plan using a role-based subagent team with two-stage review: spec compliance first, then code quality.
	Execute a plan using either a role-based subagent team or sequential subagents, with two-stage review: spec compliance first, then code quality.

[Copilot]

## Agent Teams Mode is currently outside the <host: claude-code> block, so non-Claude hosts will see an empty section header with no applicable content. Wrap the heading inside the host block, or add host-neutral/other-host content under this heading to avoid a dead section.

[Copilot]

This update only host-conditions the TaskUpdate instruction, but the surrounding bullet list still hardcodes “DM” coordination, which the PR description says should be conditioned/portable. Consider rewriting the coordination bullets in host-neutral terms (e.g., “notify the orchestrator/reviewer”) and putting any truly Claude-only DM mechanics inside the <host: claude-code> block.

[Copilot]

Placing <host: claude-code> markers inside this fenced “Task tool” template makes the block no longer directly copy/pasteable as a single prompt/config snippet (the marker lines aren’t valid in the shown format). If this block is intended to be copied verbatim, move the host-conditioned note outside the fence (or present host variants as separate fenced blocks).

[Copilot]

This update only host-conditions the TaskUpdate instruction, but the coordination bullets still assume a DM channel (“Wait for DMs…”, “DM implementer…”, etc.). If the intent is cross-host portability per the PR description, rewrite these bullets in host-neutral terms and gate any Claude-specific DM workflow under <host: claude-code>.

Code Review

The PR correctly replaces Claude-Code-specific tokens (TodoWrite, EnterPlanMode, TeamCreate, TaskUpdate, Sonnet, Opus, Haiku, etc.) with host-neutral equivalents or wraps them in <host: claude-code> blocks. Here's my assessment:

---

✅ Strengths

• Systematic token neutralization – All grep-guarded tokens in the 7 modified files are correctly wrapped; no regressions introduced.
• Clean structure in subagent-driven-development/SKILL.md – Agent Teams Mode wrapped in <host: claude-code>, Sequential Mode is properly host-neutral, and the new <host: codex> block gives Codex users concrete coordination guidance (git branch names / PR diffs as review surface).
• Model tier renaming – Opus→frontier, Sonnet→balanced applied consistently in the dot-graph labels and all Agent tool YAML blocks.
• Horizontal rule separators – The --- dividers between host-specific and neutral sections improve readability.

---

⚠️ Issues

1. Verification claim in PR description is inaccurate

The PR states:

./tests/skill-content-grep.sh
PASS: skill content is host-neutral or properly conditioned.

Running the test today exits 1 with four violations:

skills/executing-plans/SKILL.md:22:4. If no concerns: Create TodoWrite and proceed
skills/pr-monitoring/SKILL.md:23:Agent tool (general-purpose, model: sonnet, ...)
skills/alignment-check/SKILL.md:28:Dispatch a Sonnet agent to perform the comparison:
skills/alignment-check/SKILL.md:31:Agent tool (general-purpose, model: sonnet):

These are pre-existing failures not introduced by this PR, but the verification claim is still incorrect. They should either be fixed here or the PR description updated to note the test still fails due to out-of-scope files.

2. <host: claude-code> markers placed inside fenced code blocks

In spec-reviewer-prompt.md (lines 35–37) and code-quality-reviewer-prompt.md (lines 30–32), the host markers sit inside the ``` fence:

    - DM implementer when issues are found

<host: claude-code>
    - Use TaskUpdate to mark "Review spec:" tasks as completed
</host>
```  ← closing backtick belongs to the outer code block

The grep guard AWK processes raw lines without understanding markdown code fencing, so it correctly excludes `TaskUpdate` from the scan. However, when rendered, the markers appear as literal text inside a code block (the prompt template), which is visually confusing to human readers. The markers are also unindented while all surrounding prompt content uses 4-space indentation. Consider either moving the marker *outside* the fence, or adding a note above the fence explaining that host markers inside template blocks are intentional.

---

### ℹ️ Minor Notes

- **"DM" terminology** outside host blocks in the prompt templates is fine — `DM` is not in the grep guard's token list and represents a general message-passing concept.
- The `<host: codex>` "Codex Coordination Notes" section in Sequential Mode is a nice addition — it gives concrete conventions (task_id, git branch names, no shared queue) that are directly actionable.
- Renaming "Legacy Mode" → "Sequential Mode" is a better framing (legacy implies deprecated rather than "appropriate for this host").

Addressed all review findings in 787a6b1:

• Overview sentence (SKILL.md:8): updated to "Execute a plan using either a role-based subagent team or sequential subagents…" — accurate across all hosts.
• ## Agent Teams Mode heading (SKILL.md:42): moved inside the <host: claude-code> block so non-Claude hosts don't encounter an empty section header.
• Host markers inside fenced blocks (spec-reviewer-prompt.md, code-quality-reviewer-prompt.md): moved <host: claude-code> annotations outside the code fence. The base template now uses host-neutral coordination language ("Notify the code-reviewer when spec compliance passes"); the Claude-specific DM/TaskUpdate mechanics are in an annotated block below the fence.
• Pre-existing test failures (pr-monitoring/SKILL.md, alignment-check/SKILL.md): wrapped model: sonnet Agent tool blocks in <host: claude-code> with model: balanced; also fixed a pre-existing unclosed code fence in pr-monitoring/SKILL.md.

## Agent Teams Mode is outside the <host: claude-code> block, so non-Claude hosts will see an empty/placeholder section header with no content. To keep cross-host docs coherent, either wrap the header in the same <host: claude-code> block or add a host-neutral sentence under the header that explains this mode is Claude-Code-only and points readers to Sequential Mode.

Suggested change

	<host: claude-code>
	## Agent Teams Mode
	## Agent Teams Mode
	Agent Teams mode is available only in Claude Code. On other hosts, use [Sequential Mode](#sequential-mode) instead.
	<host: claude-code>

[Copilot]

The <host: claude-code> markers inside this fenced template are less indented than the surrounding list items, which makes the snippet harder to copy/paste and read as a single coherent block. Indent the opening/closing host tags to match the surrounding lines in the code fence.

Suggested change

	<host: claude-code>
	When Agent Teams is active, add to the prompt:
	- Wait for DMs from implementers saying a task is ready
	- DM code-reviewer when spec compliance passes
	- DM implementer when issues are found
	- Use TaskUpdate to mark "Review spec:" tasks as completed

Addressed in b8e5584:

• ## Agent Teams Mode heading (SKILL.md): moved the heading back outside the <host: claude-code> block and added the clarifying sentence "Agent Teams mode is available only in Claude Code. On other hosts, use Sequential Mode instead." — non-Claude hosts now see the section with context rather than either a dead header or nothing at all. The Claude-specific content (team structure, step-by-step process) remains gated inside the host block.
• spec-reviewer-prompt.md: the <host: claude-code> annotation is already outside the fenced template (from the previous fix), so the current state is clean copy-pasteable fenced block + annotated host block below.

The main PR-monitoring workflow is now entirely inside an exclusive <host: claude-code> block, which means other hosts will see almost no “Process” guidance for this skill. Consider adding a host-neutral fallback (e.g., manual gh polling steps or a generic “use your host’s background agent mechanism”) outside the host block so the skill remains usable cross-host.

[Copilot]

PR description lists Group I + III skill rewrites, but this file (and other non-listed skills like alignment-check / executing-plans) is also changed in this PR. Please update the PR description to include these additional modified skills so reviewers can correctly scope what’s being altered.

[Copilot]

This section is now fully gated behind <host: claude-code>, so non-Claude-Code hosts won’t see any instructions for how to perform the “alignment agent” step. If this skill is meant to be cross-host, add host-neutral instructions outside the block (or add additional host blocks) describing how to run the comparison when the Claude Code Agent tool isn’t available.

[Copilot]

The generic instructions say to “Notify the orchestrator”, but the Claude Code–specific addendum says to “DM team-lead”. If these refer to the same role, consider using consistent terminology (e.g., “orchestrator (team-lead)”) so the handoff target is unambiguous across hosts/modes.

Suggested change

	- DM team-lead when task is fully approved
	- DM orchestrator (team-lead) when task is fully approved

Please re-review PR-C (latest commit on skills/cross-llm-pr-c-group-iii, commit 50f070a: upgraded alignment-check + pr-monitoring to full procedure restructure, fixed orchestrator/team-lead terminology).

PR description says this PR rewrites Group I + III skills, but this file (and others like skills/alignment-check/SKILL.md / skills/executing-plans/SKILL.md) are also modified. Please update the PR description to include these additional skill changes, or split them into a separate PR if they’re out of scope for the stated goal.

[Copilot]

The alignment-agent dispatch instructions are now completely wrapped in <host: claude-code>, leaving no host-neutral guidance for other environments even though this skill is part of the autonomous pipeline. Add a generic instruction outside the host block (e.g., “use a balanced-tier model / your host’s subagent mechanism”) or provide explicit per-host alternatives so the skill remains usable cross-host.

Suggested change

	Dispatch a `balanced`-tier subagent to verify alignment. The subagent reads both documents and produces an Alignment Report:
	Use a `balanced`-tier model, subagent, or your host's equivalent task-dispatch mechanism to verify alignment. The alignment checker should read both documents and produce an Alignment Report following the instructions below.
	If your environment supports subagents, dispatch this as a focused review task. If it does not, run the same check directly with the current assistant using the same inputs and report format.

[Copilot]

The generic template says to “Notify the orchestrator” on approval, but the Claude Code Agent Teams addendum uses “DM team-lead”. Because both appear in the base template, this creates inconsistent role naming and can confuse which role to contact. Consider using one consistent role name (or explicitly mapping orchestrator ↔ team-lead) in the generic section and the host-conditioned addendum.

[Copilot]

This step used to require creating a TodoWrite/task list before execution; after the change, only Claude Code gets that instruction (inside the host block) and other hosts get no equivalent task-tracking step. If task tracking is still intended as part of the workflow, add a host-neutral instruction outside the host block (e.g., “create one task entry per plan task in your host’s task system”) and keep the TodoWrite-specific wording only as a Claude Code addendum.

Suggested change

	Create one task entry per plan task in your host's task system before starting.

[Copilot]

This skill’s core instructions for how to run the monitoring loop are now entirely inside a <host: claude-code> block, so other hosts will see only the heading with no process guidance. If the intent is cross-host portability, add a host-neutral fallback (e.g., run the same loop in the foreground / manual polling) or explicitly state that PR monitoring is Claude-Code-only and what to do elsewhere.

The heading "Sequential Handoff Mode" is inconsistent with the rest of the document (which standardizes on "Sequential Mode") and immediately tells readers to use "Sequential Mode" anyway. Rename this heading to match "Sequential Mode" (or drop the extra host-specific heading) to avoid terminology drift and duplicate sections in rendered TOCs.

Suggested change

	## Sequential Handoff Mode
	## Sequential Mode

Step 2 instructs to mark tasks as in_progress/completed, but Step 1 no longer establishes any task list/tracking mechanism for non-claude-code hosts (the only tracking instruction is now inside the <host: claude-code> block). Add a host-neutral instruction in Step 1 to create/track tasks in the current host’s task system so the status updates in Step 2 are actionable everywhere.

The host-neutral instruction says to “Spawn a background balanced-tier agent”, but background agents appear to be a Claude Code-specific capability (the actual Agent tool invocation is already inside the <host: claude-code> block). Consider rephrasing this sentence to be host-neutral (e.g., “run the Monitor Loop, preferably in a background agent if your host supports it”) or moving the background-agent wording into the Claude Code block so other hosts aren’t told to do something they may not support.

Suggested change

	Spawn a background `balanced`-tier agent that monitors the PR in a loop following the Monitor Loop procedure.
	Run the Monitor Loop procedure to monitor the PR continuously, preferably in a background agent if your host supports it.

[Copilot]

In the non-Claude host guidance, the polling loop only mentions PR checks and PR review comments; it omits checking PR reviews for "CHANGES_REQUESTED" (which the Claude Code Monitor Loop explicitly checks and uses as an exit condition). This can cause the monitor to stop while changes-requested reviews are still open. Add the equivalent gh api .../pulls/<number>/reviews polling (or otherwise instruct checking for changes-requested) and include it in the exit criteria for these hosts too.

Suggested change

	Use your host's equivalent mechanism to periodically poll `gh pr checks <number>` and
	`gh api repos/<owner>/<repo>/pulls/<number>/comments` in a loop, fixing failures and
	responding to review comments until all checks pass and no unresolved comments remain.
	Use your host's equivalent mechanism to periodically poll `gh pr checks <number>`,
	`gh api repos/<owner>/<repo>/pulls/<number>/comments`, and
	`gh api repos/<owner>/<repo>/pulls/<number>/reviews` in a loop, fixing failures,
	responding to review comments, and addressing any outstanding reviews with state
	`CHANGES_REQUESTED` until all checks pass, no unresolved comments remain, and there
	are no outstanding `CHANGES_REQUESTED` reviews.

The PR description says the full Monitor Loop procedure (steps 1–4 + commands) was moved to host-neutral prose with only the slim Agent invocation in the <host: claude-code> block, but the Monitor Loop content is still entirely inside the Claude-Code-only block. This makes non-Claude hosts miss the actual procedure and also makes “following the Monitor Loop procedure” (line 20) undefined outside that block. Consider moving the Monitor Loop steps/commands to the host-neutral section and keeping the <host: claude-code> block limited to the Agent tool wrapper that references that procedure (and similarly add/adjust other-host invocation guidance if needed).
