Shared documentation for other do-* skills, including available MCP services, discovery steps, and service-readiness checks. MCP is a way for an agent to use external tools and services.

Use it indirectly through task execution, review, and quality-assurance skills that need tool discovery or checks for running application services.

It keeps common instructions in one place and helps execution skills know which services are available and ready.

Install

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.

Any agent

npx skills add fabio-barboza/development-orchestrator --skill do-shared

Clone the repo

git clone --depth 1 https://github.com/fabio-barboza/development-orchestrator

Made for: Claude Code, Codex.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00058	$0.00466
Opus 5.5	$0.00023	$0.00186
Sonnet 5.5	$0.00012	$0.00093
Haiku 4.5	$0.00006	$0.00047

Security

Grade A, and why

do-shared 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 1mo 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

Shared Resources

Purpose

Centralizes references consumed by multiple do-* execution skills. Avoids duplication of the MCP capability registry and the discovery procedure across skills.

references/do-mcp-capabilities.md: Registry mapping each configured MCP server to its capabilities, tool prefix, runtime requirements, and unavailability handling.
references/do-mcp-discovery-instructions.md: Standard procedure for discovering MCP servers in the active AI tool's configuration file and applying the capability guard.
references/do-service-readiness.md: Standard procedure for checking, reusing, and starting services (frontend dev server, backend API, broker, database) before invoking MCP tools or E2E tests. Enforces "check first, reuse if running, start only when needed, never kill running services".

Consumers

The following skills read these references at runtime:

do-execute-task
do-execute-qa
do-execute-qa-bugfix
do-execute-review

Usage

This skill is not user-invocable. Other do-* skills cite the absolute path (e.g., do-shared/references/do-mcp-capabilities.md) when their procedure requires the registry or the discovery flow.

Error Handling

If a consumer skill cannot locate do-shared/references/do-mcp-capabilities.md, halt and report the missing dependency — do not fall back to hardcoded MCP assumptions.
If a new MCP is configured by the user but absent from the registry, add an entry to do-shared/references/do-mcp-capabilities.md following the existing schema; no skill code needs to change.

References

MCP Registry: do-shared/references/do-mcp-capabilities.md
MCP Discovery: do-shared/references/do-mcp-discovery-instructions.md
Service Readiness: do-shared/references/do-service-readiness.md

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

do-shared is a skill published in the GitHub repository fabio-barboza/development-orchestrator (30 stars, last pushed 17d ago), licensed MIT. It adds 58 tokens to every session and 466 once invoked, about $0.0002 per session on Opus 5.5. 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.
