The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond.
Delivery workflow harness for agent coding tools
Dely adds a managed workflow around agent work: you ask for a change, approve the design, let one session implement it, and let another session review it. The repo ships the workflow contract, agent-specific plugin packaging, and setup files that write the right guidance into your project.
Builders who want agent sessions to move through design, implementation, and review in a repeatable way.
You can turn a loose request into a reviewed pull request without re-explaining the process at each step.
What it does
Design approval step
Stops the run at a design contract before implementation starts.
Isolated implementation and review sessions
Uses separate sessions so the implementer and reviewer do not share the same working context.
Orca supervision and preflight checks
Depends on Orca CLI capabilities and checks that orchestration is available before delivery starts.
Project setup into AGENTS.md
Writes one managed block into `AGENTS.md` so the workflow can run inside the project.
Plugin packaging for multiple harnesses
Ships installable plugin definitions for Claude Code, Codex, Cursor, Grok, Antigravity, and Copilot.

README
dely
Ask for a change; Dely takes it through design approval, implementation, independent review, and a pull request you merge.

Quickstart
Install Orca, then Dely.
- Install the desktop app.
- Register the CLI (it ships with the app): Settings → General → Orca CLI. See the CLI overview.
- Enable orchestration: Settings → Experimental. See orchestration.
- Preflight:
orca open
orca status --json
orca orchestration run-list --json
dely:delivery stops if this preflight fails. On Linux the binary is
orca-ide (see the install docs).
Optional agent skills orca-cli and orchestration:
https://www.onorca.dev/docs/cli/skills
Then:
- Install
delyin the harness (Install). - Open a session in the project.
- Invoke
dely:setup(optional). - Ask for a change.
Project setup
In the project, invoke dely:setup.
It asks Quick (this harness for both phases) or Customize (pick harness,
model, and effort for implement and review), then writes one managed
block into AGENTS.md. Skip it and dely:delivery uses the current
harness and that harness's defaults.
Install
The plugin is dely, from the dely marketplace at
https://github.com/hieuphung97/dely.git. The skill name is delivery;
invoke it as dely:delivery. Kiro CLI has no plugin verb; use
### Kiro CLI below.
Claude Code
claude plugin marketplace add https://github.com/hieuphung97/dely.git
claude plugin install dely@dely
claude plugin list # verify it is installed
claude plugin update dely # update (restart required to apply)
claude plugin uninstall dely # uninstall
Codex CLI
codex plugin marketplace add https://github.com/hieuphung97/dely.git
codex plugin add dely@dely
codex plugin list # verify it is installed
codex plugin marketplace upgrade # update: see below
codex plugin remove dely@dely # uninstall
codex plugin marketplace add --ref <ref> pins the marketplace to a tag
such as v0.17.0 or an exact full commit SHA. There is no
codex plugin update: use codex plugin marketplace upgrade. Do not use
codex plugin install.
Grok Build
grok plugin install hieuphung97/dely
grok plugin list # verify it is installed
grok plugin update dely # update
grok plugin uninstall dely # uninstall
grok plugin install takes a git URL, GitHub shorthand, or local path.
Pin with @tag, for example hieuphung97/dely@v0.17.0. A local directory
needs --trust.
Antigravity CLI
agy plugin install https://github.com/hieuphung97/dely.git
agy plugin list # verify it is installed
agy plugin install https://github.com/hieuphung97/dely.git # refresh: no `plugin update` subcommand
agy plugin uninstall dely # uninstall
agy plugin install takes a git URL or a local path.
Cursor Agent CLI
cursor-agent plugin marketplace add https://github.com/hieuphung97/dely.git
# verify it is installed
cursor-agent plugin marketplace list
# re-index, no fetch
cursor-agent plugin marketplace update dely
# refresh: remove and re-add (remove drops the marketplace, not the plugin)
cursor-agent plugin marketplace remove dely
cursor-agent plugin marketplace add https://github.com/hieuphung97/dely.git
The snapshot is addressed by commit, so marketplace update only re-indexes
and does not fetch. Remove and re-add the marketplace to pick up new commits,
then choose Uninstall from the Installed tab and install again from the
Marketplace tab of the /plugin panel.
Add the marketplace first with cursor-agent plugin marketplace add, then in
a Cursor Agent session type /plugin and press Enter. Open the Marketplace
tab, type dely in the search box, press Enter on dely (dely), and choose
Install for you (user scope) (or Install for all collaborators on this repository (project scope)).
To uninstall, open the Installed tab, select dely, and choose
Uninstall. cursor-agent plugin marketplace remove removes the marketplace
entry and leaves the plugin installed.
Type /dely to filter the palette to Dely's /delivery and /setup.
GitHub Copilot CLI
copilot plugin marketplace add https://github.com/hieuphung97/dely.git
copilot plugin install dely@dely
copilot plugin list # verify it is installed
copilot plugin update dely # update
copilot plugin uninstall dely # uninstall
copilot plugin marketplace remove dely # removes the marketplace, not the plugin
Kiro CLI
npx skills add hieuphung97/dely --agent kiro-cli --global --skill delivery --skill setup
npx skills list --agent kiro-cli --global # verify it is installed
npx skills update --global # update
npx skills remove --agent kiro-cli --global --skill delivery --skill setup # uninstall
Invoke the skills in a Kiro CLI session as /delivery and /setup.

How Dely works
Ask for a change. Approve the design when asked. Dely implements, a different session reviews, then opens a PR. You merge. A Spike investigates only — no delivery run.
The workflow contract is skills/delivery/SKILL.md.
Troubleshooting
dely:deliverystops immediately. Orca is not running or a required capability is absent, including orchestration. Run the Quickstart preflight, then retry.- A harness still runs the old workflow after you edited this checkout. You edited the source, not an installed copy. Reinstall or update the plugin in the harness.
- Codex still behaves the same after
codex plugin marketplace upgrade. Confirm the remote has new commits. A delivery already running keeps the plugin version from its start; open a new session after the upgrade. AGENTS.mdpins don't seem to apply in Claude Code. Put@AGENTS.mdinCLAUDE.md; Claude Code does not readAGENTS.mddirectly.
