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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00016 | $0.00387 |
| Opus 5 | $0.00008 | $0.00193 |
| Sonnet 5 | $0.00003 | $0.00077 |
| Haiku 4.5 | $0.00002 | $0.00039 |
Grade A, and why
develop 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 4d 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.
What it actually says
Develop
Guided feature development through a 6-phase SDLC pipeline with plan persistence.
Quick Start
/develop add user authentication # Full pipeline
/develop add logout button --auto # Autonomous mode
/develop create plan for X --plan-only # Plan only
/develop @arkhe/specs/01-auth/ # Resume existing
/develop @arkhe/specs/01-auth/ --verify-arch # Verify architecture alignment
/develop @arkhe/specs/01-auth/ --verify-impl # Verify implementation completeness
/develop @arkhe/specs/01-auth/ --verify-arch --verify-impl # Full audit
Flags
| Flag | Effect |
|---|---|
--plan-only |
Stop after Phase 2 (save plan, don't implement) |
--validate |
Enable opus-level validation in Phase 4 |
--phase=N |
Execute specific phase only |
--auto |
Autonomous mode (no checkpoints) |
@path |
Resume from existing plan |
--verify-arch |
Verify implementation matches plan.md architecture |
--verify-impl |
Verify implementation meets spec.md requirements |
Implementation
Invoke the Skill tool with skill name "core:sdlc-develop" and arguments: $ARGUMENTS
The skill handles all six phases: Discovery → Requirements → Architecture → Workstreams → Implementation → Summary.
For detailed phase documentation, see core/skills/sdlc-develop/SKILL.md.
What this file has done since we first saw it
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.

develop is a command published in the GitHub repository joaquimscosta/arkhe-claude-plugins (21 stars, last pushed 20d ago), licensed MIT. It adds 16 tokens to every session and 387 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
