feat(cli): forward --skills flag in ACP mode

[NakePranob]

Description

Forward the --skills flag from the hermes acp CLI command to the ACP adapter's argument parser, enabling users to preload skills when launching the ACP server.

hermes acp --skills "my-skill" --skills "another-skill"
# or comma-separated:
hermes acp --skills "my-skill,another-skill"

Changes

• hermes_cli/main.py — forward args.skills to acp_main()

1 file, +3 lines.

• fix(acp): preload startup skills from --skills #30560 — Open competing PR that forwards --skills through the full ACP stack (CLI → entry → HermesACPAgent → SessionManager → build_preloaded_skills_prompt) with tests. This PR is intentionally scoped to the CLI layer only — the adapter-side skills plumbing is handled by companion PR feat(acp): adapter compliance v1 — capabilities, resource blocks, config modes, skills #57510 (feat(acp): adapter compliance v1). Together feat(acp): adapter compliance v1 — capabilities, resource blocks, config modes, skills #57510 + feat(cli): forward --skills flag in ACP mode #57511 cover the same ground as fix(acp): preload startup skills from --skills #30560, split across two focused PRs by concern.
• feat(acp): adapter compliance v1 — capabilities, resource blocks, config modes, skills #57510 — Companion adapter compliance PR that implements the full ACP skills stack (session-level skill preloading, entry-point integration, tests).

This was generated by AI during triage.

Related: #24466 (issue), #30560 (open competing PR). #30560 is the broader canonical fix — it forwards --skills from the CLI AND plumbs the skills through the full ACP stack (entry → HermesACPAgent → SessionManager → build_preloaded_skills_prompt) with tests. This PR is a subset (the CLI-forward half only), so it's related rather than a duplicate; a human should pick one path.

Thanks for the triage, @alt-glitch. Agreed that #30560 covers the same ground more broadly.

We intentionally scoped this PR to the CLI layer only because:

• The adapter-side skills plumbing (entry → HermesACPAgent → SessionManager → build_preloaded_skills_prompt) is already implemented in our companion PR feat(acp): adapter compliance v1 — capabilities, resource blocks, config modes, skills #57510 (feat(acp): adapter compliance v1), which includes full integration tests.
• Splitting by concern (CLI vs adapter) keeps both PRs focused and reviewable — feat(acp): adapter compliance v1 — capabilities, resource blocks, config modes, skills #57510 is already +892 lines; adding more scope there would make it unwieldy.

So #57511 (CLI-forward) + #57510 (adapter plumbing) together deliver the same outcome as #30560, just split across two focused PRs. Marking as related rather than duplicate.

Updated the PR body to clarify this relationship.

Thanks for isolating the CLI handoff. The reported gap is present on current main, but this change is not functional by itself.

Problems

• hermes_cli/main.py:12815-12826 currently drops args.skills, so the premise is valid. However, the proposed forwarded --skills is not accepted by acp_adapter/entry.py:116-146; its parser defines no such argument and calls parse_args() at line 146.
• The documented hermes acp --skills ... form is also not parsed by the ACP subcommand: hermes_cli/subcommands/acp.py:14-52 declares no --skills flag.
• Even after parsing, current ACP startup constructs HermesACPAgent() without startup skills (acp_adapter/entry.py:260), and session agent construction has no preload-prompt input (acp_adapter/session.py:584-645).

Suggested changes

• Integrate this handoff with the adapter/session preload path described in companion #57510 (or the broader #30560), and add an end-to-end regression test that verifies the startup skill reaches ACP session construction.
• Support or correct the post-subcommand syntax shown in the PR body.

Automated hermes-sweeper review.

Current acp_adapter.entry._parse_args() has no --skills argument (acp_adapter/entry.py:116-146), so this makes globally supplied skills fail argument parsing rather than preload them. Please land this with the adapter/session parser and injection path, plus coverage.
