## MCP Code-Indexing Tooling
This repo configures two MCP servers for structural code analysis, registered in `opencode.jsonc`:
| Server | Purpose | Runtime |
|---|---|---|
| `ast-grep` | Structural pattern search (AST-level grep) | `uvx` (Python/uv) |
| `codebase-memory` | Relationship mapping, dependency graphs, blast-radius analysis | `codebase-memory-mcp` binary |
### Prerequisites
- `uvx` available on `PATH` (for `ast-grep`)
- `codebase-memory-mcp` binary installed and on `PATH`
### Intended usage layering
When analyzing code, prefer tools in this order to minimize overhead:
1. **`ast-grep` first** — structural pattern matching; fastest and most targeted
2. **`codebase-memory` next** — relationship/blast-radius queries when structure alone is insufficient
### Role allocation (summary)
Per-agent tooling scopes are defined in each agent's guidance file under `agents/`. The high-level allocation:
- **coder**: `ast-grep` only for targeted implementation discovery; avoid `codebase-memory` unless explicitly needed
- **explorer / researcher / sme / reviewer / tester**: `ast-grep` + `codebase-memory`
- **critic / designer / librarian**: no code-indexing tooling guidance (use standard tools)
Detailed per-agent behavioral guidance lives in `agents/*.md` files and is not duplicated here.

Memory uses one persistent system: **basic-memory**.

- **Always parallelize independent work.** Any tool calls that do not depend on each other's output must be issued in the same message as parallel calls — never sequentially. This applies to bash commands, file reads, and subagent delegations alike.
- Before issuing a sequence of calls, ask: *"Does call B require the result of call A?"* If not, send them together.
## Skill Loading Policy
- Relevant skills are **not optional**. When a task matches a skill's trigger conditions, the lead must load that skill proactively before proceeding with ad hoc execution.
- Keep skill usage operational: use skills to drive planning, decomposition, debugging, verification, and workflow enforcement instead of relying on generic reminders.
- `AGENTS.md` defines this as policy; concrete skill trigger rules and enforcement behavior belong in `agents/lead.md`.
## Human Checkpoint Triggers
When implementing features, the Lead must stop and request explicit user approval before dispatching coder work in these situations:
@@ -313,3 +350,69 @@ Before implementing a feature, the lead must verify its understanding of what th
When in doubt, ask. A 30-second clarification prevents hours of rework on a fundamentally misunderstood feature.
This complements the Clarification Rule above — that rule covers *ambiguous requirements*; this rule covers *requirements that seem clear but may be misunderstood*. The test: "If I'm wrong about what this means, would I build something completely different?" If yes, verify.
## Proactive Bug Search
Do not limit quality work to the requested diff. The Lead should actively search for likely related defects before and after implementation.
### Minimum proactive bug-hunt pass
For any non-trivial feature or bug fix, inspect nearby risk surfaces in addition to the primary edit point:
- sibling components/handlers in the same feature area
- duplicated or copy-pasted logic paths
- recent churn hotspots and TODO/FIXME comments
- adjacent validation, error handling, empty-state, and permission logic
- parallel codepaths that should stay behaviorally consistent
This pass is not open-ended archaeology; it is a focused search for bugs that are likely to be coupled to the requested work.
### Discovery and review expectations
- During DISCOVER, include a short "likely bug surfaces" list in the findings when the task is non-trivial.
- During EXECUTE, require reviewer and tester prompts to check for **related regressions and likely adjacent bugs**, not just direct spec compliance.
- If proactive bug hunting finds unrelated non-blocking issues, record them in project memory or a backlog note rather than silently folding them into the current task.
- If a discovered bug is blocking correctness of the current task, treat it as in-scope and explicitly add it to the plan.
### Bug-fix workflow
- Prefer reproduction-first debugging: capture the failing scenario, failing test, or concrete bug path before fixing when feasible.
- After the fix, re-run the same scenario as the primary verification step.
- For bug fixes without an automated regression test, document the exact manual reproduction and re-verification path.
## Planning Rigor
Planning should be detailed enough to reduce rework, not just to describe intent.
### Plan minimums
Every non-trivial plan must include, per task or feature:
- the exact user-visible outcome
- explicit acceptance criteria
- edge cases and error cases
- non-goals / what is intentionally out of scope
- verification method
- impacted files, systems, or integration surfaces
- likely breakage or regression surfaces
### Required pre-mortem
Before EXECUTE, add a short pre-mortem section to the plan for non-trivial work:
- what is most likely to fail
- which assumption is most fragile
- what would force a redesign or user checkpoint
- what regression is easiest to miss
The goal is to surface rework risks early, before coder dispatch.
### Retry learning loop
When review or testing fails and a retry is needed, update the plan with a brief note covering:
- what was misunderstood or missed
- what new constraint was discovered
- what changed in the execution approach
Do not resend the same plan unchanged after a failed cycle unless the failure was purely mechanical.

- likely touches more than 2 files
- more than one independently meaningful task
- user-visible behavior changes
- cross-system integration or data flow changes
- verification requires more than one command or more than one validation mode

- 2+ plausible technical approaches with materially different tradeoffs.
- Unfamiliar framework/API/library/protocol behavior is central to the change.
- Auth/security/permissions/secrets/trust boundaries are involved.

# Creating Agents
Use this skill when you need to add or revise an agent definition in this repo.
## Agents vs Skills
- **Agents** define runtime behavior and permissions in `agents/*.md`.
- **Skills** are reusable instruction modules under `skills/*/SKILL.md`.
- Do not treat agent creation as skill creation; each has different files and checks.
## Source of Truth
1. Agent definition file: `agents/<agent-name>.md`
2. Dispatch permissions for new dispatchable agents: `agents/lead.md`
- `permission.task.<agent-name>: allow` must be present for lead dispatch.
3. Human-readable roster: `AGENTS.md`
- Keep the roster table synchronized with actual agent files.
4. Runtime overrides: `opencode.jsonc`
- May override/disable agent behavior.
- Does **not** register a new agent.
## Agent File Conventions
For `agents/<agent-name>.md`:
- Use frontmatter first, then concise role instructions.
- Keep tone imperative and operational.
- Include only permissions and behavior needed for the role.
- Align with existing files such as `agents/lead.md` and `agents/coder.md`.
Typical frontmatter fields in this repo include:
- `description`
- `mode`
- `model` (for subagents where needed)
- `temperature`
- `permission`
- `permalink`
Mirror nearby agent files instead of inventing new metadata patterns.
Note: `agents/lead.md` is the only `mode: primary` agent. New agents should normally mirror a comparable subagent and use `mode: subagent` with an explicit `model`.
## Practical Workflow (Create or Update)
1. Inspect `agents/lead.md` and at least one similar `agents/*.md` file.
2. Create or edit `agents/<agent-name>.md` with matching local structure.
3. If the agent must be dispatchable, add `permission.task.<agent-name>: allow` in `agents/lead.md`.
4. Update `AGENTS.md` roster entry to match the new/updated agent.
5. Review `opencode.jsonc` for conflicting overrides/disable flags.
## Manual Verification Checklist (No Validation Script)
Run this checklist before claiming completion:
- [ ] `agents/<agent-name>.md` exists and frontmatter is valid/consistent with peers.
- [ ] Agent instructions clearly define role, scope, and constraints.
- [ ] `agents/lead.md` includes `permission.task.<agent-name>: allow` if dispatch is required.
- [ ] `AGENTS.md` roster row exists and matches agent name/role/model.
- [ ] `opencode.jsonc` does not unintentionally disable or override the new agent.
- [ ] Terminology stays consistent: agents in `agents/*.md`, skills in `skills/*/SKILL.md`.

# Creating Skills
Use this skill when you need to add or revise an opencode skill under `skills/`.
## Skills vs OpenAI/Codex Source Model
- Treat this repo as **opencode-native**.
- Do **not** use OpenAI/Codex-specific artifacts such as `agents/openai.yaml`, `init_skill.py`, `quick_validate.py`, or `scripts/references/assets` conventions from the old source model.
- A skill is discovered from `skills/*/SKILL.md` only.
## Required Structure
1. Create a folder at `skills/<skill-name>/`.
2. Add `skills/<skill-name>/SKILL.md`.
3. Keep `<skill-name>` equal to frontmatter `name`.
Frontmatter must contain only:
```yaml
---
name: <skill-name>
description: <what it does and when to load>
permalink: opencode-config/skills/<skill-name>/skill
---
```
## Naming Rules
- Use lowercase kebab-case.
- Keep names short and action-oriented.
- Match folder name and `name` exactly.
## Body Writing Rules
- Write concise, imperative instructions.
- Lead with when to load and the core workflow.
- Prefer short checklists over long prose.
- Include only repo-relevant guidance.
## Companion Notes (`*.md` in skill folder)
Add companion markdown files only when detail would bloat `SKILL.md` (examples, deep procedures, edge-case references).
- Keep `SKILL.md` as the operational entrypoint.
- Link companion files directly from `SKILL.md` with clear “when to read” guidance.
- Do not create extra docs by default.
## Practical Workflow (Create or Update)
1. Inspect 23 nearby skills for local style and brevity.
2. Pick/update `<skill-name>` and folder path under `skills/`.
3. Write or revise `SKILL.md` frontmatter (`name`, `description`, `permalink` only).
4. Draft concise body sections: purpose, load conditions, workflow, red flags/checks.
5. Add minimal companion `.md` files only if needed; link them from `SKILL.md`.
6. Verify discovery path and naming consistency:
- file exists at `skills/<name>/SKILL.md`
- folder name == frontmatter `name`
- no OpenAI/Codex-only artifacts introduced
