Add omp (Oh My Pi) as a STABLE, detected client surface with full
four-layer integration: MCP server registration, durable instructions,
skill, and three direct-MCP tiered subagent profiles (Scout/Verify/
Auditor). This matches Claude Code's integration depth — omp subagents
have direct MCP access (confirmed via ablation testing), unlike
parent-handoff-only clients (Pochi, Cursor, Rovo, Augment).
Schema (agent_clients.h):
New CBM_AGENT_CLIENT_OMP enum value, positioned before COUNT.
Profile (agent_clients.c):
- stability: CBM_AGENT_STABLE (auto-detected, auto-installed)
- capabilities: MCP | INSTRUCTIONS | SKILL | AGENT
No HOOK — omp's context event is fire-once advisory only; the
recommended upstream path is skill + agents + MCP, not TS hooks.
- detection_command: "omp" (specific enough per existing clients)
- marker: ~/.omp/agent (omp-managed config root)
- resolve_path: ~/.omp/agent/mcp.json
- json_client: true (uses standard mcpServers JSON edit path)
- agent_json_canonical: added to type:"stdio" branch alongside
GitLab Duo and Visual Studio (omp's schema expects this field)
Dialect (agent_profiles.h/.c):
New CBM_GRAPH_DIALECT_OMP, direct-capable (not in handoff-only list).
- tool prefix: "mcp__codebase_memory_mcp_" (single underscore,
hyphens→underscores — verified at runtime via omp device inventory)
- render: YAML frontmatter with tools (read/grep/glob + tier-specific
MCP tool allowlist), read-summarize: false (exact source verification
for evidence tiers — omp's read returns structural summaries by
default), autoloadSkills: [codebase-memory] (subagents start blank)
Install/uninstall (cli.c):
- install_omp_durable_context: writes AGENTS.md + skill +
3 tiered agent profiles to ~/.omp/agent/
- uninstall_omp_durable_context: removes managed block + skill +
tiered profiles
- legacy_omp_verify_agent_content: migration source for prior installs
- Wired into install_agent_client_registry and
uninstall_agent_client_registry loops
Design decisions (documented for reviewers):
1. No HOOK capability: omp's tool_call event can only block/pass (no
augmentation channel like Claude's additionalContext). A context-
event nudge was tested but is advisory-only and excluded from the
upstream path to keep the PR minimal.
2. read-summarize: false: omp's read tool returns structural summaries
by default; Tier 2/3 require exact snippets for material claims.
3. autoloadSkills: omp subagents start with no conversation history;
without autoload the skill decision matrix is never loaded.
4. Direct-capable (not handoff): ablation testing confirmed omp
subagents can call mcp__* tools directly. write→xd:// dispatch
does NOT work in subagents ("xd:// is not mounted in this session").
Test coverage:
- test_agent_clients.c: omp in stable_ids (19 entries), capabilities
array, json_schemas (type:stdio assertion), foreign_entries
- test_agent_profiles.c: omp in direct_dialects array, direct-capable
assertion, dedicated test verifying direct profile has
mcp__codebase_memory_mcp_ prefix + read-summarize + autoloadSkills,
and handoff profile excludes MCP tools
- test_cli.c: required_agents updated to 44, all 43→44 / 37→38 string
contracts updated across README/npm/index.html/llms.txt/main.c
Build: scripts/build.sh passes (exit 0).
Tests: scripts/test.sh passes (exit 0, all suites green).
Lint: scripts/lint.sh has one pre-existing error in pass_lsp_cross.h
(parameter name mismatch imp_keys/imp_vals vs imp_names/imp_qns),
unrelated to this change.
