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 12 tools

The MCP server exposes 12 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_criteria auto-creates a goal when none is active
• start_goal begins a new independent goal (fresh criteria + task plan)
• switch_goal moves between goals; list_goals shows all with status
• reset_goal deletes 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)

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_modules on Windows, /usr/local/lib/node_modules on 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.url path 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

1. Set criteria — set_acceptance_criteria with role=reviewer (you verify) or role=agent (agent self-claims, you confirm later)
2. Set task plan — set_task_plan to decompose the goal into atomic tasks with deliverables and dependencies
3. Execute — update_task_status as tasks progress (pending → in_progress → completed)
4. Validate — validate_criterion with evidence_type=command for high-confidence evidence
5. Check — can_complete_goal to verify all required criteria are formally passed

OpenClaw native plugin

The @cckyros/goal-acceptance-openclaw package is an OpenClaw native plugin that registers all 12 tools directly in-process (no MCP stdio overhead).

openclaw plugins install "npm:@cckyros/goal-acceptance-openclaw@rc"

Note: The @rc tag 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 12 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-acceptance system prompt section with task progress and next-actionable ordering
• Intercepts agent/turn-stopping and 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, passed is marked self-claimed. Optional verbose (default false).
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.

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:

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	12 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.
