flow-deliver

flow-deliver is a skill for Claude Code from nyldn/claude-octopus. It costs 23 tokens per session (7,741 once invoked), scanned A, original, MIT.

A delivery-stage review process that uses outside AI providers to validate, score, and review work. It is part of the Double Diamond, a four-stage design and development process.

In plain words
What is it for?
Use it to review a project, document, or software change for quality, completeness, and readiness.
Why use it?
It checks whether development is complete and gathers structured feedback before delivery.

Skill for Claude Code

Written for Claude Code: disable-model-invocation in frontmatter. Also seen: agent in frontmatter; reads .claude/ paths; mentions CLAUDE.md.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

About the project

Claude Octopus is an orchestration project that sends research, design, and coding tasks to Claude Code and other AI model providers so their results can be compared. Developers use it for multi-model work, disagreement detection, reviews, persistent context, and an optional workflow that moves from discovery through delivery. The catalogue entries are its commands, skills, agents, instructions, hooks, plugins, and settings.

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 A, and why

flow-deliver scanned grade A with 0 findings 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 10d ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

{{PREAMBLE}}

Pre-Delivery: State Check

Before starting delivery:

  1. Read .octo/STATE.md to verify Develop phase complete
  2. Update STATE.md:
    • current_phase: 4
    • phase_position: "Delivery"
    • status: "in_progress"
# Verify Develop phase is complete
if [[ -f ".octo/STATE.md" ]]; then
  develop_status=$("${HOME}/.claude-octopus/plugin/scripts/octo-state.sh" get_phase_status 3)
  if [[ "$develop_status" != "complete" ]]; then
    echo "⚠️ Warning: Develop phase not marked complete. Consider completing development first."
  fi
fi

# Update state for Delivery phase
"${HOME}/.claude-octopus/plugin/scripts/octo-state.sh" update_state \
  --phase 4 \
  --position "Delivery" \
  --status "in_progress"

⚠️ EXECUTION CONTRACT (MANDATORY - CANNOT SKIP)

This skill uses ENFORCED execution mode. You MUST follow this exact sequence.

STEP 1: Detect Work Context (MANDATORY)

Analyze the user's prompt and project to determine context:

Knowledge Context Indicators:

  • Document terms: "report", "presentation", "PRD", "proposal", "document", "brief"
  • Quality terms: "argument", "evidence", "clarity", "completeness", "narrative"

Dev Context Indicators:

  • Code terms: "code", "implementation", "API", "endpoint", "function", "module"
  • Quality terms: "security", "performance", "tests", "coverage", "bugs"

Also check: What is being reviewed? Code files -> Dev, Documents -> Knowledge

Capture context_type = "Dev" or "Knowledge"

Step 1b: Detect Dev Subtype (if Dev context)

When context_type is Dev, determine the subtype to inject domain-appropriate validation criteria into the review prompt. Append the matching validation supplement after the user's prompt when calling orchestrate.sh in Step 4.

Subtype Trigger keywords Validation supplement
frontend-ui "page", "widget", "component", "UI", "HTML", "CSS", "form", "dashboard", "layout" Verify: all referenced files exist (scripts, stylesheets, images). Check ARIA labels and roles, keyboard navigability, touch target sizes (44px min). Flag innerHTML usage. Confirm progressive enhancement (fallbacks for navigator.share, localStorage, etc). Test self-containment: does this work if opened/run with zero setup?
cli-tool "CLI", "command-line", "terminal", "script", "flag", "argument" Verify: --help flag works, exit codes are meaningful (0/1/2), stderr vs stdout used correctly, argument edge cases handled (missing args, invalid input, --unknown-flag).
api-service "API", "endpoint", "REST", "GraphQL", "gRPC", "server", "route" Verify: input validation at every endpoint, consistent error response format, auth on protected routes, rate limiting considered, schema/contract documented.
infra "deploy", "terraform", "docker", "CI", "pipeline", "Kubernetes", "helm" Verify: operations are idempotent, no hardcoded secrets, rollback path exists, health checks included, destroy operations require confirmation.
data "ETL", "pipeline", "migration", "schema", "database", "SQL" Verify: migrations are reversible, data validation at ingestion, backup strategy documented, no data loss on failure.
general Default if no subtype matches No supplement — use standard review criteria.

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.
