feat(agent): harness adapter — miner-auto-dev profile + driving loop (#781)

[JSONbored]

Closes #781

What & why

Phase 2 (#770) — final piece. Extends init-client into a first-class auto-dev profile that wires the miner's local harness (Claude Code/Codex/Cursor) to the gittensory MCP + the plan→implement→push driving loop. With this, Phase 2 is complete.

How

New miner-auto-dev agent profile in the published CLI (packages/gittensory-mcp/bin/gittensory-mcp.js). Unlike the existing human-approved-only profiles, it is gate-throttled:

• Wires the Phase-2 tools — gittensory_run_local_scorer (feat(agent): local gittensor-root scorer MCP wrapper #782), gittensory_build_plan/plan_status/record_step_result (feat(agent): multi-step action DAG executor #783), gittensory_open_pr/file_issue/apply_labels/post_eligibility_comment/create_branch/delete_branch (feat(agent): miner write-tools (open_pr/file_issue/...) — local-executed #780), plus preflight / slop / predict-gate.
• 5-step driving loop: select reward-optimal work (respect the open-PR gate, credibility floor, time-decay) → plan a step DAG → harness implements locally → gate-check (scorer + slop + preflight) → push via the local write-tools only when the gate passes.
• formatAgentProfile renders the driving loop; the init-client note for an auto-dev profile reflects local execution after the gate (not the human-approved framing of the other profiles).

Boundary

Every GitHub write is run by the miner's own harness with its own credentials via a write-tool's returned command — gittensory supplies content + the gate only, never performs the write, never sees source.

Tests

The new profile round-trip (Phase-2 tools wired, driving loop present + gate-throttled, local-execution boundary + note, no token leakage). Existing profile tests unchanged (the new profile is intentionally not in the human-approved-only set). Full suite green (2118); CLI smoke + node --check ok.

Note: the published MCP CHANGELOG is regenerated at mcp-release time (not a per-PR gate), so it's intentionally untouched here.

Reviewed 2 changed file(s) — two independent AI reviewers.

Changed files: packages/gittensory-mcp/bin/gittensory-mcp.js, test/unit/mcp-cli-basics.test.ts

Suggested action: ✅ Safe to merge — both reviewers found no blocking issues.

Reviewer A · gpt-oss-120b — recommends ✅ merge
This PR adds a new "miner-auto-dev" agent profile with a detailed driving loop and updates CLI output to reflect its gate‑throttled local execution, plus a test verifying the new behavior.

Suggestions

• Confirm that the TypeScript type for agent profiles includes the new optional fields (drivingLoop, boundaries) to avoid compile errors.
• Update any documentation or README that lists available agent profiles to mention the new miner-auto-dev profile.
• Consider adding a test for a profile without a drivingLoop to ensure the CLI note fallback still works as expected.

Worth double-checking

• Potential TypeScript type mismatch if the profile interface is not extended for the new fields.
• Public output must continue to avoid forbidden terms; verify that the new description does not introduce any.

Reviewer B · mistral-small-3.1-24b-instruct — recommends ✅ merge
This PR adds a new agent profile 'miner-auto-dev' to the Gittensory MCP CLI. The profile includes detailed instructions for a plan-implement-push loop, recommended tools, and safety boundaries. The changes are well-documented and include corresponding tests.

Suggestions

• Consider adding a brief description of the new profile in the README or documentation to inform users about its purpose and usage.
• Ensure that the new profile's driving loop and safety boundaries are clearly communicated in any related documentation or user guides.

Worth double-checking

• Verify that the new profile does not introduce any security risks, especially regarding the handling of GitHub writes and credentials.
• Ensure that the new profile's driving loop and safety boundaries are thoroughly tested to prevent any unintended behavior or security vulnerabilities.
