Corentic Package Manager (CPM)

A CPM package is an agent package consisting of an APM manifest plus a team configuration (team-profile.yaml). The Corentic Package Manager translates this package into the native configuration of a target harness.

Translation targets:

Target harness	Status
oh-my-opencode-slim	✅ implemented
oh-my-pi	planned
Codex / Claude / Copilot	vision

Deterministic – the CPM does not guess. It assumes no availability and never picks models automatically.

CPM package                 User                        Runtime
apm.yml +            +   model-mapping.yaml   →   cpm render  →  .opencode/
team-profile.yaml        (model class →               oh-my-opencode-slim.json
(roles, model             concrete model ID)          (or later: native config
 classes, MCPs/skills)                                of another harness)

Prerequisites

• Python 3.10+ with PyYAML (pip install pyyaml)
• OpenCode with the oh-my-opencode-slim plugin installed
• A CPM package with a team-profile.yaml

Quickstart

# 1. Create the model mapping – interactively, choosing from your opencode models
python3 cpm.py init --fill

# 2. Guided: read team profile, check/fill mapping, render
cd <project>
python3 /path/to/cpm.py setup --package /path/to/package

# 3. Activate
opencode          # project config gets loaded
/preset acme-job-applications
# Reload OpenCode -> team is active (by design: no hot-swap)

Alternatively manually:

# 1. Create the model mapping once
mkdir -p ~/.config/cpm
cp examples/model-mapping.yaml ~/.config/cpm/model-mapping.yaml
$EDITOR ~/.config/cpm/model-mapping.yaml   # adapt to your own models

# 2. Validate (dry run)
python3 cpm.py check --package examples/package

# 3. Render
cd <project>
python3 /path/to/cpm.py render --package /path/to/package

The three files

File	Owned by	Purpose	Edit manually?
team-profile.yaml	Package author	Roles, model classes, MCP/skill allowlists per role	Yes (author)
~/.config/cpm/model-mapping.yaml	User	Model class → concrete model ID (+ optional variant/temperature)	Yes (user)
.opencode/oh-my-opencode-slim.json	generated	Preset with concrete model IDs	No – always re-render

Plus a provenance file .opencode/oh-my-opencode-slim.cpm-provenance.json documenting which role received which model.

Command reference

python3 cpm.py init   [--mapping FILE] [--fill]          # create/fill mapping
python3 cpm.py setup  --package DIR [--mapping F] ...    # guided flow
python3 cpm.py render --package DIR [--mapping F] [--output F] [--dry-run]
python3 cpm.py check  --package DIR [--mapping F]        # dry-run validation

init – create the mapping

Creates ~/.config/cpm/model-mapping.yaml (if not present). With --fill, all PLACEHOLDER classes are asked interactively: the CPM lists every model from your opencode.json(c), you pick by number or enter a model ID manually.

setup – guided flow

The one-command path: shows the team profile in plain language, creates a missing mapping, interactively asks for missing model classes (same selection as init --fill), renders and prints the activation steps.

render / check

Option	Default	Meaning
--package	.	CPM package directory containing team-profile.yaml
--mapping	~/.config/cpm/model-mapping.yaml	Local mapping table
--output	<package>/.opencode/oh-my-opencode-slim.json	Target file
--team-file	team-profile.yaml (alternatively team.yaml)	Alternative profile filename

Merge behavior: Existing presets in the target file remain untouched; only the preset for this team ID is replaced. Multiple packages coexist in the same project. Activation is explicit via /preset <name>.

Team profile schema (corentic.team-profile/v1)

schema: corentic.team-profile/v1
id: acme.job-applications          # becomes the preset name (namespaced)
description: ...

roles:
  - id: researcher                 # domain role
    purpose: ...                   # becomes prompt/description for custom agents
    runtime_agent: librarian       # optional: harness builtin or 'custom'
                                   # (default: role id as custom agent)
    model_class: fast-research     # required, must exist in the mapping
    capabilities:
      mcps: [websearch, openviking]  # MCP allowlist ([] = none)
      skills: [job-application]      # skill allowlist ([] = none)

The runtime_agent field is deliberately harness-neutral: the adapter decides how the role is represented in the target harness. Builtins recognized by the oh-my-opencode-slim adapter: orchestrator, oracle, librarian, explorer, fixer, designer, council, observer. Everything else (or runtime_agent: custom) creates a custom agent including prompt and orchestratorPrompt derived from the purpose field.

Mapping formats

model_classes:
  fast-research: ollama/qwen3.5:9b              # simple
  high-reasoning:                               # extended
    model: ollama/qwen3.6:35b-a3b-q4_K_M
    variant: thinking
    temperature: 0.3

All extra fields are passed through 1:1 into the agent entry of the preset.

What the CPM checks

1. Team profile present, schema known, id and roles present
2. Every model_class has a mapping entry (otherwise error with fix hint)
3. MCPs matched against ~/.config/opencode/opencode.json(c) (warning, not fatal)
4. Roles without MCPs/skills -> note

Examples

Example	Based on	Team
examples/package/	Own job-application package (OpenViking + ShareLaTeX)	acme.job-applications – Researcher, Writer, Checker, Notifier
examples/microsoft-design-review/	Official microsoft/apm-sample-package	acme.design-review – Reviewer (Oracle), Style-Checker (Fixer), Accessibility-Auditor
examples/microsoft-issue-autopilot/	Official apm-issue-autopilot from the microsoft/apm repo	acme.issue-autopilot – Triager, Shepherd, PR-Writer, Reviewer (+ GitHub MCP)

The two Microsoft examples are thin CPM wrappers: their own apm.yml pulls the official package as a versioned APM dependency (microsoft/apm-sample-package#v1.0.0 or monorepo subpath microsoft/apm/packages/apm-issue-autopilot) and only adds the team recommendation.

cd corentic-package-manager/examples

# Dry run: what would be generated?
python3 ../cpm.py check --package package --mapping model-mapping.yaml
python3 ../cpm.py check --package microsoft-design-review --mapping model-mapping.yaml
python3 ../cpm.py check --package microsoft-issue-autopilot --mapping model-mapping.yaml

# Render into the example project
python3 ../cpm.py render --package package \
  --mapping model-mapping.yaml \
  --output package/.opencode/oh-my-opencode-slim.json

Expected result: preset acme-job-applications with five agents – orchestrator, librarian (alias researcher), custom agent writer, oracle (alias checker), custom agent notifier. The researcher gets no LaTeX access, the writer sees no job-search tools, the notifier gets no external access at all.

Then:

cd package && opencode
/preset acme-job-applications

Troubleshooting

Problem	Cause/Fix
Model class X is not mapped	Add to the mapping, re-render
Warning: MCP ... not configured	Set up the MCP in opencode.jsonc or remove it from the profile
/preset does not show anything new	Reload OpenCode after rendering; presets do not apply mid-session
Preset lost after manual editing	The file is generated – changes belong in the mapping or team profile
YAML errors	Follow the line number in the error message

Deliberate limits

• The CPM does not start agents and orchestrates nothing at runtime – that is the job of the target harness.
• MCP/skill allowlists are capability scoping, not a sandbox. Irreversible actions need server-side authorization + human approval.
• Model availability is checked against opencode.json(c) names, not via API health checks.
