Add Rule as a first-class canonical kind (rules/<name>.md, loaded like
agents) and propagate it the way each harness actually loads it:
- claude-code: native ~/.claude/rules directory symlink (preserves rule
path-scoping frontmatter); rules NOT folded into CLAUDE.md.
- opencode/kilo/zed/crush: fold rule bodies into the global AGENTS.md
always-on instructions file (frontmatter stripped). crush has no global
instructions file, so register the absolute AGENTS.md path in
options.context_paths (defaults are re-prepended at load, so nothing is
clobbered).
- goose: fold into ~/.config/goose/.goosehints.
- cagent: fold into the per-agent instruction.
Also:
- Wire markdown agents to opencode (~/.config/opencode/agents) and fix the
kilo agents symlink: plural ~/.config/kilo/agents (singular "agent" is a
silent no-op on current Kilo CLI).
- Add ManagesAgents/ManagesRules to HarnessCapabilities + ImportResult.Rules;
claude-code/opencode import rules/agents round-trip.
- Centralize instruction selection in Bundle.InstructionText /
InstructionTextWithRules (replaces per-adapter override duplication).
- init scaffolds + imports rules; README capability matrix gains
Agents/Rules columns with native-vs-folded footnotes.
Grounded each harness's sink against official docs + config source this
session. Gate: gofmt, go vet, go test -race ./..., golangci-lint (0),
govulncheck (clean).
