Introduction
goal-acceptance

English | 中文
Acceptance-criteria-driven goal completion for autonomous AI agents.
Prevents agents from prematurely declaring "done" by locking immutable acceptance criteria before work begins, tracking validation status with evidence, linking criteria to task progress, respecting dependency ordering, and enforcing completion checks.
Advantages
1. Cross-platform compatibility
goal-acceptance works with any AI agent platform that supports MCP or Agent Plugins. One package, multiple runtimes:
| Platform | How it connects | Turn-stopping enforcement |
|---|---|---|
| Claude Code | MCP stdio server | Model voluntarily calls tools |
| Cursor | MCP stdio server | Model voluntarily calls tools |
| Devin | MCP stdio server | Model voluntarily calls tools |
| OpenClaw | Native plugin (@cckyros/goal-acceptance-openclaw) or Agent Plugin bundle | Model voluntarily calls tools |
| DeepSeek Harness | Cordis plugin (@cckyros/dsh-goal-acceptance) | Yes — agent.steer() forces continuation |
| Any MCP client | stdio MCP server | Model voluntarily calls tools |
| Any Agent Plugins client | plugin.json + mcp.json + skills | Model voluntarily calls tools |
| Any JS/TS runtime | Core library (@cckyros/goal-acceptance-core) | Programmatic —you control it |
The core state machine is zero-dependency and runs in any JS/TS runtime (Node.js, Bun, Deno, browser). The MCP server adds only the MCP SDK. The Cordis plugin adds DeepSeek Harness integration. You pick the layer you need.
2. MCP server with 13 tools
The MCP server exposes 13 tools covering the full goal-acceptance lifecycle:
- Criteria management: set, get, amend
- Task plan management: set task plan, get task plan
- Validation: validate criterion with typed evidence
- Progress tracking: update task status
- Completion gate: can complete goal
- Multi-goal management: start goal, list goals, switch goal, reset goal
See MCP Tools below for the full list.
Multi-goal isolation
Each goal has its own event file under ${PLUGIN_DATA}/goals/{goalId}.json —multiple projects and windows can share one server without lock conflicts:
set_acceptance_criteriaauto-creates a goal when none is activestart_goalbegins a new independent goal (fresh criteria + task plan)switch_goalmoves between goals;list_goalsshows all with statusreset_goaldeletes a messed-up goal so you can start over- The active goal survives server restarts (
current-goal.txt)
3. Dual-role validation (anti self-grading)
set_acceptance_criteria accepts a role parameter (agent / reviewer /
dual). When role=agent, validate_criterion marks passed as
selfClaimed=true — can_complete_goal blocks completion until a reviewer
formally confirms. This breaks the "self-grading" loop where an agent both
does the work and signs off on it.
4. Typed evidence
validate_criterion accepts evidence_type (command / file / url /
text). text evidence is flagged lowConfidence=true so reviewers can
spot subjective claims at a glance. command evidence (test output, CLI
results) is high-confidence.
5. Task decomposition with dependency validation
set_task_plan lets you decompose a goal into atomic tasks, each with a
concrete deliverable. The engine validates: unique IDs, unambiguous
descriptions, non-empty deliverables, no self-dependencies, no unknown
dependencies, and no dependency cycles (including indirect cycles).
6. Event-sourced persistence
All state changes are append-only events. The engine replays events on every read, enabling durable persistence, exact state restoration across restarts, and a full audit trail of every decision.
7. Slim responses by default
MCP tool responses are slim by default (4-field summary). Pass verbose=true
for the full summary. This minimizes token overhead during normal operation.

## Quick Start
### Core library (any JS/TS runtime)
```sh
npm install @cckyros/goal-acceptance-core
import { GoalAcceptanceEngine, InMemoryAcceptanceStore } from '@cckyros/goal-acceptance-core'
const engine = new GoalAcceptanceEngine(new InMemoryAcceptanceStore())
// Lock criteria before work begins
await engine.setCriteria([
{ id: 'api-200', description: 'GET /health returns 200', required: true, method: 'test', taskIds: ['task-1', 'task-2'] },
{ id: 'docs', description: 'README updated', required: false, method: 'manual', dependsOn: ['api-200'] },
])
// Update task progress as work proceeds
await engine.updateTaskStatus({ taskId: 'task-1', status: 'completed' })
await engine.updateTaskStatus({ taskId: 'task-2', status: 'completed' })
// When all linked tasks are done, the criterion is "ready to validate"
const summary = engine.summarize()
console.log(summary.readyToValidate.map(c => c.id)) // —['api-200']
// Record validation with evidence
await engine.validateCriterion({
criterionId: 'api-200',
status: 'passed',
evidence: 'curl /health —HTTP 200 OK',
})
// Check if goal can complete
const { allowed, reason } = engine.canComplete()
console.log(allowed, reason)
// —true, undefined
MCP server (Devin, Claude Code, Cursor, etc.)
Three installation methods, pick one:
Method A: Global install (recommended)
npm install -g @cckyros/goal-acceptance-mcp
Find the installed bin path, then add to your MCP client config:
{
"mcpServers": {
"goal-acceptance": {
"command": "node",
"args": ["/path/to/global/node_modules/@cckyros/goal-acceptance-mcp/bin/mcp-server.mjs"],
"env": {
"PLUGIN_DATA": "/path/to/persistent/data"
}
}
}
}
Find the global path:
npm root -g(e.g.C:\nvm4w\nodejs\node_moduleson Windows,/usr/local/lib/node_moduleson macOS/Linux).
Method B: npx (no pre-install needed)
npx downloads the package on-demand to a temporary cache. No global install required, but adds a few seconds of startup latency on first run.
{
"mcpServers": {
"goal-acceptance": {
"command": "npx",
"args": ["-y", "@cckyros/goal-acceptance-mcp"],
"env": {
"PLUGIN_DATA": "/path/to/persistent/data"
}
}
}
}
Windows + nvm users: If npx fails to start the server, use Method A instead. nvm junctions can cause
import.meta.urlpath mismatch in some Node.js versions.
Method C: Local install (project-level)
npm install @cckyros/goal-acceptance-mcp
{
"mcpServers": {
"goal-acceptance": {
"command": "node",
"args": ["./node_modules/@cckyros/goal-acceptance-mcp/bin/mcp-server.mjs"],
"env": {
"PLUGIN_DATA": "/path/to/persistent/data"
}
}
}
}
Devin CLI config
Devin uses %APPDATA%\devin\mcp_config.json (Windows) or ~/.config/devin/mcp_config.json (macOS/Linux). Add the goal-acceptance entry to mcpServers using any method above, then restart Devin.
Standalone usage
# In-memory (resets on restart)
node ./node_modules/@cckyros/goal-acceptance-mcp/bin/mcp-server.mjs
# Persistent across restarts
PLUGIN_DATA=/path/to/data node ./node_modules/@cckyros/goal-acceptance-mcp/bin/mcp-server.mjs
The server writes acceptance-events.json under $PLUGIN_DATA. If PLUGIN_DATA
is not set, state is in-memory only (lost on restart).
Typical workflow
- Set criteria —
set_acceptance_criteriawithrole=reviewer(you verify) orrole=agent(agent self-claims, you confirm later) - Set task plan —
set_task_planto decompose the goal into atomic tasks with deliverables and dependencies - Execute —
update_task_statusas tasks progress (pending—in_progress—completed) - Validate —
validate_criterionwithevidence_type=commandfor high-confidence evidence. Defaultrole=agent: passed criteria are self-claimed. - Confirm —
confirm_criterion(independent reviewer agent only) with freshevidence_type=command/file/urlevidence. Converts self-claimed to formal pass. - Check —
can_complete_goalto verify all required criteria are formally passed
OpenClaw native plugin
The @cckyros/goal-acceptance-openclaw package is an OpenClaw native plugin that registers all 13 tools directly in-process (no MCP stdio overhead).
openclaw plugins install "npm:@cckyros/goal-acceptance-openclaw@rc"
Note: The
@rctag is required because the package is in pre-release. Once a stable version is published, the tag can be omitted.
After install, restart the gateway:
openclaw gateway restart
Verify:
openclaw plugins inspect goal-acceptance
# Status: loaded, Format: openclaw
The 13 tools are now available in OpenClaw sessions. Shape: non-capability is normal for tool plugins —tools are registered via defineToolPlugin, not the capability system.
Agent Plugin (portable bundle format)
The MCP package doubles as an Agent Plugin package. Point any Agent Plugins-capable client at the package root:
node_modules/@cckyros/goal-acceptance-mcp/
├── plugin.json # Agent Plugin manifest
├── mcp.json # stdio MCP server config
└── skills/ # Portable Agent Skills
├── set-acceptance-criteria/SKILL.md
├── get-acceptance-criteria/SKILL.md
├── validate-criterion/SKILL.md
├── update-task-status/SKILL.md
├── amend-acceptance-criteria/SKILL.md
└── can-complete-goal/SKILL.md
The client will discover the skills, start the stdio MCP server, and surface the tools.
DeepSeek Harness (Cordis plugin)
The Cordis plugin is the only variant that can force the agent to continue
working when it tries to stop early. It intercepts agent/turn-stopping and
steers the agent back with dependency-aware priority ordering.
npm install @cckyros/dsh-goal-acceptance
# cordis.yml
plugins:
goal-acceptance:
autoSteerUncompleted: true
maxSteeringTurns: 5
The plugin:
- Registers 5 model tools (
set/get/validate_acceptance_criteria,update_task_status,amend_acceptance_criteria) - Injects a
policy:goal-acceptancesystem prompt section with task progress and next-actionable ordering - Intercepts
agent/turn-stoppingand steers the agent back with dependency-aware priority ordering when required criteria are still pending
Note: The Cordis plugin requires DeepSeek Harness packages as peer dependencies (
@deepseek-ai/dsh-agent,dsh-llm,dsh-session,dsh-tools,dsh-system-prompt,dsh-goal,dsh-invariants,cordis). Install it inside a DeepSeek Harness project where these are already present. The core and MCP packages build independently.
MCP Tools
| Tool | Description |
|---|---|
set_acceptance_criteria | Lock the criteria list. Each criterion may link to task IDs and declare dependencies. Optional role parameter (agent/reviewer/dual, default dual) controls self-claim behavior. Must be called before implementation. |
get_acceptance_criteria | Read current criteria, task progress, summary, task plan, ready-to-validate list, and next-actionable ordering. Optional verbose parameter (default true; pass false for slim summary only). |
set_task_plan | Set and lock the task decomposition plan. Each task must have a unique id, unambiguous description, and concrete deliverable. Dependency cycles are rejected. Requires criteria to be locked first. |
get_task_plan | Read the current task decomposition plan with live task statuses. |
validate_criterion | Record status (pending/in_progress/passed/failed/blocked/not_run) and evidence. passed and failed require evidence. Optional evidence_type (command/file/url/text, default text). When role=agent (default), passed is marked self-claimed. Optional verbose (default false). |
confirm_criterion | Reviewer-only. Confirm a self-claimed passed criterion with independent re-verification evidence. Requires evidence_type of command/file/url (text rejected). Converts self-claimed to formal pass, unblocking can_complete_goal. Must be called by an independent reviewer agent, not the agent that did the work. |
update_task_status | Update a linked task's status (pending/in_progress/completed/failed). When all tasks linked to a criterion are completed, it becomes ready to validate. Optional verbose (default false). |
amend_acceptance_criteria | Append new criteria after the initial lock. Requires a reason. Existing criteria are not modified. |
can_complete_goal | Check whether all required criteria are formally passed (self-claimed does not count). Returns { allowed: boolean, reason?: string }. |
start_goal | Start a new independent goal with fresh state (optional title). The new goal becomes active. Use when the current goal is locked and you need a new task. |
list_goals | List all goals with ID, title, criteria counts, and active flag. |
switch_goal | Switch the active goal to an existing goal by ID. |
reset_goal | Delete the current goal and all its data permanently. |
Criterion Status Lifecycle
┌──────────— —pending ——initial state after setCriteria
└────┬─────— — ┌──────────┼──────────— — — — — — — ┌──────────—┌────────—┌────────— │in_progress——passed ——failed — └──────────—└────────—└────────— — — — — — ┌────────— — — │blocked — — — └────────— — — ┌────────— └──────────┘─────│not_run — └────────— ```
| Status | Meaning | Evidence required |
|--------|---------|-------------------|
| `pending` | Not yet started | No |
| `in_progress` | Being worked on | No |
| `passed` | Verified successful | Yes |
| `failed` | Verified unsuccessful | Yes |
| `blocked` | Cannot verify in current environment | No |
| `not_run` | Explicitly skipped (non-required only) | No |
## Completion Gate
`canComplete()` returns `{ allowed: boolean, reason?: string }`:
- **Allowed**: all required criteria are formally `passed` (not self-claimed), or no criteria are locked.
- **Not allowed**: any required criterion is `pending`, `in_progress`, `failed`,
`blocked`, or `not_run`.
- **Not allowed (self-claimed)**: all required criteria are `passed` but some are
`selfClaimed=true` (set by an agent, not yet reviewer-confirmed). The reason
will indicate how many are awaiting reviewer confirmation.
## Event Sourcing
The engine is event-sourced. The store holds an append-only list of:
- `goal-acceptance/set` —locks the criteria list (with role)
- `goal-acceptance/task-plan` —locks the task decomposition plan
- `goal-acceptance/validate` —updates one criterion's status (with evidence type, self-claimed flag)
- `goal-acceptance/task-update` —updates a linked task's status
- `goal-acceptance/amend` —appends new criteria after the initial lock
On every read, the engine replays events from the store. This enables:
- Durable persistence (file, database, session log)
- Replay-exact state restoration
- Audit trail of all decisions
### Custom Store
Implement `GoalAcceptanceStore` for your persistence backend:
```typescript
import type { GoalAcceptanceStore, GoalAcceptanceEvent } from '@cckyros/goal-acceptance-core'
class MyDbStore implements GoalAcceptanceStore {
get events(): readonly GoalAcceptanceEvent[] {
// Return all events in append order
}
async append(event: GoalAcceptanceEvent): Promise<void> {
// Persist the event
}
}
Four-Way Compatibility
| Capability | Cordis plugin | MCP server | Agent Plugin | OpenClaw native |
|---|---|---|---|---|
| Model tools | set/get/validate/update_task/amend | 13 tools (see MCP Tools) | same as MCP | same as MCP (in-process) |
| System prompt / Skills | policy:goal-acceptance | skills/ | skills/ | skills/ |
| Turn-stopping enforcement | yes (agent.steer(), dependency-aware) | no | no | no |
| Cross-client portable | no (Harness only) | yes (any MCP client) | yes (any Agent Plugins client) | no (OpenClaw only) |
| Persistent state | dsh-session log | $PLUGIN_DATA/acceptance-events.json | same as MCP | same as MCP |
| Dual-role validation | no | yes (role parameter) | yes | yes |
| Typed evidence | no | yes (evidence_type parameter) | yes | yes |
| Task decomposition plan | no | yes (set_task_plan / get_task_plan) | yes | yes |
| Slim responses | no | yes (verbose parameter) | yes | yes |
| In-process calls (no stdio) | yes | no | no | yes |
The Cordis plugin is the only variant that can force the agent to continue working when it tries to stop early. The MCP, Agent Plugin, and OpenClaw native variants rely on the model voluntarily calling the tools and following skill instructions.
