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.

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 5.1 | $0.00059 | $0.01893 |
| Opus 5 | $0.00030 | $0.00946 |
| Sonnet 5 | $0.00012 | $0.00379 |
| Haiku 4.5 | $0.00006 | $0.00189 |
Grade A, and why
dev-pipeline 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 6d 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.

Development Pipeline Skill
Use this skill when the user asks to build a feature, fix a bug, or implement a plan using the multi-agent development pipeline.
Spec-driven phasing (gated workflow)
The run_dev_pipeline MCP tool implements a 4-phase gated workflow. Do not advance to the next phase until the current one is validated.
SPECIFY ──→ PLAN ──→ TASKS ──→ IMPLEMENT

Phase 1 — Specify
Before producing the spec, surface assumptions explicitly:
ASSUMPTIONS I'M MAKING:
1. This runs in the existing nexus-agents MCP server (not a new process)
2. New CLI flag goes through the existing dispatch table (cli-command-catalog.ts)
3. Storage uses the existing FileAuditStorage path (not a new backend)
4. Output schema follows the Result<T, E> pattern per CLAUDE.md
→ Correct me now or I'll proceed with these.
The spec's purpose is to surface misunderstandings before code gets written. Silent assumptions are the most dangerous form of misunderstanding.
Phase 2 — Plan
Convert the spec into a sequenced plan: which files change, in what order, with what tests. Each step references the canonical path (per CLAUDE.md "Canonical Paths") so future readers can navigate.
Phase 3 — Tasks
Break the plan into atomic tasks suitable for fan-out. Each task has:
- A clear acceptance criterion (the test that asserts success)
- A bounded output (no "list all", per
.rules/subagent-coordination.md) - A scope (one directory or one canonical path, not "the codebase")
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.

dev-pipeline is a skill published in the GitHub repository nexus-substrate/nexus-agents (18 stars, last pushed today), licensed MIT. It adds 59 tokens to every session and 1,893 once invoked, about $0.0003 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.
