implement

A command for carrying out implementation tasks listed in speckit task files, with progress tracking and required checks. It can run one task, a range, a phase, or a named group.

In plain words
What is it for?
It helps implement planned coding tasks, show project status, run task batches, resume unfinished work and apply the required verification steps.
Why use it?
It makes the task-execution process repeatable by checking project status first and requiring validation hooks before implementation begins. It also supports continuing from the last recorded point.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 9 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 2,705 The whole file, excluding the scripts and references it only reads on demand.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

implement scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 437 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Implement

Execute tasks from speckit/*-tasks.md with batch execution, gates, and mandatory hooks.

User Input

$ARGUMENTS

You MUST consider the user input before proceeding (if not empty).

Usage

/implement TASK-001           # Single task
/implement TASK-001..TASK-005 # Range
/implement "Phase 1"          # All in phase
/implement @foundation        # All with group
/implement --continue         # Resume from last
/implement                    # No argument - triggers status check

MANDATORY: Pre-Execution Hooks

CRITICAL: These hooks MUST execute BEFORE any task implementation begins.

Pre-Hook 1: Load Project Status

ALWAYS read .claude/memory/project-status.md first to understand:

  • Current phase and progress
  • What was completed in previous sessions
  • Any blockers or failed criteria from last run
  • Recommended next actions
Read: .claude/memory/project-status.md

Extract:
- Current Phase: [phase name]
- Progress: [X]/[Y] tasks ([Z]%)
- Last Activity: [date] - [what was done]
- Pending Actions: [list]

Pre-Hook 2: Validate Argument / Show Status

IF no argument provided OR invalid argument:

## Current Project Status

| Metric | Value |
|--------|-------|
| Project | Knowledge MCP |
| Current Phase | Phase [N]: [Name] |
| Progress | [X]/[Y] tasks ([Z]%) |
| Last Updated | [DATE] |

### Phase Progress
| Phase | Status | Completed/Total |
|-------|--------|-----------------|
| Phase 1 | ✓ COMPLETE | 6/6 |
| Phase 2 | IN PROGRESS | 3/8 |
| Phase 3 | PENDING | 0/5 |

### Recommended Next Action

Based on current state, you should run:

/implement "Phase 2"


Or to continue from where you left off:

/implement --continue


### Available Selectors

| Selector | What It Does |
|----------|--------------|
| `TASK-XXX` | Execute single task |
| `TASK-XXX..TASK-YYY` | Execute range |
| `"Phase N"` | Execute all in phase |
| `@group` | Execute all with group tag |
| `--continue` | Resume from last position |
| `--all` | Execute all pending tasks |

**Please specify which tasks to implement.**

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

implement is a command published in the GitHub repository ddunnock/claude-plugins (12 stars, last pushed 5mo ago), licensed MIT. It adds 9 tokens to every session and 2,705 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
