From 1a9ac7ca1b047f4da022e5d5d255eac82a4d33a5 Mon Sep 17 00:00:00 2001 From: Pavel Date: Thu, 30 Jul 2026 15:24:06 +0300 Subject: [PATCH 01/12] Add migration helper for Tabnine CLI to opencode MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds migration_helper/ subtree with: - skills/migrate-from-tabnine-cli/ — interactive wizard skill that discovers Tabnine CLI (or Gemini CLI) configuration on disk, asks the user per category what to migrate, and translates fields into opencode's schema. Includes reference docs for source paths and field-by-field translation rules. - commands/migrate.md — /migrate slash command as an entry point to the wizard. - install.sh — bash installer that copies the skill and command into either ~/.config/opencode/ (default) or ./.opencode/ (--project). Shows a diff and prompts skip/overwrite/rename on collisions. Supports --overwrite to bypass prompts. - README.md — install (script or manual copy) and usage docs. - LICENSE — MIT, subtree-scoped. Root README gets one new section linking to migration_helper/README.md. --- README.md | 4 + migration_helper/LICENSE | 21 ++ migration_helper/README.md | 120 +++++++++ migration_helper/commands/migrate.md | 5 + migration_helper/install.sh | 184 ++++++++++++++ .../skills/migrate-from-tabnine-cli/SKILL.md | 171 +++++++++++++ .../references/mapping.md | 227 ++++++++++++++++++ .../references/source-map.md | 209 ++++++++++++++++ 8 files changed, 941 insertions(+) create mode 100644 migration_helper/LICENSE create mode 100644 migration_helper/README.md create mode 100644 migration_helper/commands/migrate.md create mode 100755 migration_helper/install.sh create mode 100644 migration_helper/skills/migrate-from-tabnine-cli/SKILL.md create mode 100644 migration_helper/skills/migrate-from-tabnine-cli/references/mapping.md create mode 100644 migration_helper/skills/migrate-from-tabnine-cli/references/source-map.md diff --git a/README.md b/README.md index 8f72d4a..f69ff2c 100644 --- a/README.md +++ b/README.md @@ -16,6 +16,10 @@ Installation, sign-in, and usage instructions are in the documentation: Supported platforms: macOS (x64, arm64), Linux (x64, arm64), and Windows (x64, arm64). +## Migrate from Tabnine CLI + +If you're switching from Tabnine CLI (or Gemini CLI), the [Migration helper](migration_helper/README.md) copies your MCP servers, skills, subagents, and slash commands into opencode.

Order: + +1. **Target scope for this session** — global (`~/.config/opencode/`) or project (`./.opencode/` in the current worktree). Ask once at the start of the session. It can be overridden per-category if the user wants. +2. **MCP servers** — multi-select from the discovered list. Warn on any name conflict with an existing `mcp.` in the target `opencode.json`. +3. **Skills** — multi-select. Warn on any target-folder collision. +4. **Agents** — multi-select. For each selected agent, ask a follow-up: `subagent` (default) or `primary` mode. Explain the difference in one sentence. +5. **Commands** — multi-select if any were found. +6. **Extensions** — for each extension found, list what it bundles (MCPs / skills / agents / commands) and ask whether to unpack each component into the target. Do not migrate the extension manifest itself; opencode has no equivalent. + +Never present a "migrate all" shortcut without also showing the individual list. The user asked for a wizard — respect that. + +## Phase 3 — Translate and write + +Per opencode's schema (see `references/mapping.md` next to this SKILL.md for the full field-by-field table). Highlights: + +### MCP servers + +Tabnine stores `mcpServers: { name: { url?, httpUrl?, command?, args?, env?, headers?, type? } }` in `settings.json`. + +Translate to opencode `mcp: { name: { type, url|command, headers?, env?, enabled } }`: + +- If the source has a `url` or `httpUrl` field → `type: "remote"`, `url: `. +- If the source has a `command` field → `type: "local"`, `command: [, ...args]` (opencode requires an array). +- Preserve `headers` and `env` verbatim. +- Set `enabled: false` if the enablement file marks this server disabled; otherwise `enabled: true` (opencode's default). +- Never copy `mcp-oauth-tokens.json`. OAuth tokens will not carry over; the user will re-authenticate on first use. Tell them this after writing. + +Merge into `opencode.json`'s `mcp` object rather than replacing it. Preserve `$schema`, `plugin`, and any other keys already present. If the file doesn't exist, create it with `"$schema": "https://opencode.ai/config.json"`. + +### Skills + +Copy the entire skill folder (SKILL.md and all sibling files) to `/skills//`. Frontmatter is compatible verbatim — both systems require `name` and `description`. Do not edit the SKILL.md. + +If the skill body references Gemini-specific tools (`gemini`, `gemini -p`, `tui-tester`, etc.), do **not** silently rewrite them. Instead, after copying, note the affected skills to the user with one line each so they can fix them later. Rewriting prompts changes semantics. + +### Agents + +Read the source `.md`, split frontmatter from body, translate frontmatter, keep body verbatim. + +Field mapping (drop anything not listed): + +| Tabnine frontmatter | opencode frontmatter | Notes | +| --- | --- | --- | +| `name` | `name` | Keep. | +| `description` | `description` | Keep. | +| `display_name` | — | Drop. opencode has no equivalent. | +| `model` | `model` | Keep only if it's already `provider/model-id`. Values like `inherit`, `claude-4-opus`, `Claude 4.8 Opus` must be dropped (subagents inherit by default; primaries fall back to global `model`). | +| `temperature` | `temperature` | Keep. | +| `max_turns` | `steps` | Rename. Keep integer value. | +| `timeout_mins` | — | Drop. opencode has no per-agent timeout. Mention this to the user for that agent. | +| `tools` | — | Drop. opencode uses per-tool `permission` instead. Suggest an equivalent permission block only if the user asks — do not guess. | +| `mcp_servers` | — | Drop. opencode agents cannot declare private MCPs. Offer to move the definitions into top-level `mcp` in `opencode.json`. | +| — | `mode` | Add. Use the value the user chose in Phase 2 (`subagent` or `primary`). | + +Write to `/agent/.md` (opencode also accepts `agents/`, but the singular form is canonical in the schema examples — pick one and stick with it; if the target already has a plural folder, use that). + +### Commands + +Tabnine command TOMLs look like: + +```toml +description = "..." +prompt = """ +Multi-line prompt with {{args}} or $ARGUMENTS references +""" +``` + +Translate to opencode markdown: + +```markdown +--- +description: "…" +--- + + +``` + +Replace Tabnine's `{{args}}` placeholder with opencode's `$ARGUMENTS`. Leave `$ARGUMENTS`, `$1`, `$2` alone if already present. + +Write to `/command/.md`. Nested subfolders in the source (`commands/foo/bar.toml`) become filename-mangled names or nested folders — mirror the source structure. + +### Extensions + +Do not migrate `tabnine-extension.json` as a unit. For each component the user opted into, apply the rules above to the extension's `mcpServers`, `skills/`, `agents/`, `commands/` entries. Prepend the extension name to the migrated item's `name` field if a collision exists (`-`), and mention this to the user. + +## Phase 4 — Post-write summary and warnings + +After all writes succeed, print a summary: + +- What was written (grouped by category, with target paths). +- Any items that were **skipped** due to collisions or user opt-out. +- Any agents where `tools`, `mcp_servers`, `timeout_mins`, or `model` fields were dropped, with a one-liner suggesting where the user should look next. +- Any skills whose bodies reference Gemini-specific tools, flagged for manual review. +- OAuth reminder for any migrated remote MCP servers (Atlassian, Mixpanel, GitHub, etc.): tokens do not carry over. +- **Restart reminder**: "Quit and restart opencode for these changes to take effect. Running sessions keep using the already-loaded config." + +Note about Claude Code skills at `~/.claude/skills`: opencode auto-scans this path already. Do NOT copy skills from there into `~/.config/opencode/skills/` unless the user explicitly asks — you'd end up with duplicates (opencode will load both and warn). If discovery finds Claude Code skills, tell the user they're already visible to opencode and skip them by default. + +## When things go wrong + +- **`ConfigInvalidError` on startup after migration**: the user's `opencode.json` has a rejected field. Recover with `OPENCODE_DISABLE_PROJECT_CONFIG=1 opencode` (project) or by manually editing the global file. Point them at the escape hatches in the `customize-opencode` skill. +- **Duplicate skill name warning at load time**: two skills with the same `name` exist in scanned paths. Rename one or delete the older copy. +- **MCP server appears but returns auth errors**: normal on first use — re-authenticate via the MCP's OAuth flow. Do not attempt to copy tokens from `~/.tabnine/agent/mcp-oauth-tokens.json`. +- **User wants to reverse the migration**: the wizard doesn't delete Tabnine sources, so reversing means deleting the newly created files under `/{mcp entries, skills/*, agent/*.md, command/*.md}`.

Tabnine's tools is a YAML list of ALLOWED tool names (evals/concurrency-safety.eval.ts:14), so dropping it granted the migrated agent every tool including bash, write and edit — a privilege escalation created by the migration. Translate it to a deny-by-default permission block instead, with a name map (read_file -> read, run_shell_command -> bash, ...) since the two systems name tools differently. Flag the cases where the mapping unavoidably widens privilege (replace -> edit gains write) and list unmapped names rather than dropping them. MCP timeout defaults differ by two orders of magnitude: Tabnine MCP_DEFAULT_TIMEOUT_MSEC is 600000 (mcp-client.ts:103), opencode defaults to 5000.

New Phase 2.5 resolves every selected item to an absolute destination and prints a plan — target root and how it resolved, MCP endpoints being granted, each planned write with a create/backup/overwrite/rename verb, and the permission changes including any that widen privilege — then stops for explicit approval. A category selection is no longer approval to write. Phase 4 now reconciles actuals against that plan and names any unplanned write, so a partial failure leaves a manifest instead of a glob. Doubles as the dry-run mode. Core rule 3 now requires a timestamped backup before overwriting skills, agents and commands, matching what opencode.json already got; overwrite was previously unrecoverable for those. Collision handling was specified three different ways (rule 3 offered skip/overwrite/rename, Phase 2 only warned, Phase 3 merged without asking). Unified: Phase 2 flags, Phase 2.5 asks and records the verb, opencode.json stays the documented exception. QA pass on my own edits, all found by reading the result rather than by the checks: - "see core rule on privilege above" pointed at a rule that does not exist; now points at the tool map and states the risk inline. - The unknown-frontmatter-key claim said such keys "silently do nothing". opencode passes them to the model provider as request options, so a stale key can reach the provider and be rejected. - Phase 5's preamble asserted a restart was required and then explained why it was not. Rewritten: the commands are accurate immediately, the restart is for the user's running session. - The Phase 1 inventory example printed "MCPs (3)" including a built-in, demonstrating the exact confusion the rule below it forbids. - Duplicated Phase 1 lead-in, a stale "in this order" reference to a table that is gone, an orphaned Claude-skills paragraph left inside Phase 5, and a double blank line. - "Worth verifying on disk" replaced with three explicit checks. Moved verification and troubleshooting into references/verification-and-recovery.md with a JIT trigger, since both are only needed on request or on failure. Gave source-map.md a real trigger and deleted the vague "see references/" pointer the rubrics call out by name. Added a Gotchas section consolidating the facts that were buried mid-paragraph.

Discovery only searched the working directory and below. Tabnine also walks upward from the session directory to the project root (findUpwardGeminiFiles), so running the wizard from packages/api would silently miss the repository-root context file — usually the most important one. Discovery now searches upward as well, stopping at the repository root or $HOME, and states that ancestor and cwd files migrate cleanly because opencode loads from the session directory upward. Only files below it carry the loading caveat. The downward search can also match many files in a monorepo, which would make the plan unreadable and the per-file prompt unusable. Above roughly ten matches the wizard now groups them by depth with counts and sizes, and offers to accept them as a group, as a group with named exceptions, or individually. Grouping keeps the prompt readable without removing the decision. --- migration_helper/skills/migrate-tabnine-context/SKILL.md | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) diff --git a/migration_helper/skills/migrate-tabnine-context/SKILL.md b/migration_helper/skills/migrate-tabnine-context/SKILL.md index 1aafc8b..aef69c7 100644 --- a/migration_helper/skills/migrate-tabnine-context/SKILL.md +++ b/migration_helper/skills/migrate-tabnine-context/SKILL.md @@ -21,7 +21,12 @@ You are migrating the user's Tabnine CLI context/memory files into opencode's `A 1.
