sync-docs

A documentation-maintenance rule set for keeping related project documents consistent. It covers files such as README.md, onboarding pages, agent guides, and skills.

In plain words
What is it for?
Updating a documented convention across all relevant files after editing any documentation surface.
Why use it?
The same project rules can become different across documents when only one copy is updated. It makes related documentation changes part of the same task.

Made for: Claude Code, Codex.

Per session 79 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.
When invoked 1,473 The whole file, excluding the scripts and references it only reads on demand.

Origin original No closer match found in the catalogue.
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

sync-docs 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Keep the documentation in sync

This project documents the same conventions in several places, for different audiences. They must agree. Whenever you change one, you are responsible for propagating the change to every other surface that covers the same thing — in the same unit of work, not "later." A convention that says one thing in the README and another in a skill is worse than no docs.

The documentation surfaces (the canonical set)

Surface Audience / purpose
documentation.html The big Stripe-style single-page onboarding site for humans. Deep, narrative, examples.
README.md The full human onboarding doc in the repo. Deep explanations, kept in sync with documentation.html.
docs/conventions.txt The terse, authoritative rulebook. When rules conflict, this wins — so it must always reflect the decision.
AGENTS.md Canonical, tool-agnostic agent guide (Cursor/Codex/Copilot read this directly). Golden rules + skill index.
CLAUDE.md Claude Code entry point — imports AGENTS.md; Claude-specific notes only.
.claude/skills/*/SKILL.md Step-by-step playbooks an agent executes. The operational form of the conventions.
database/schema.sql Documentation of every table (column-order / naming template at top).
docs/*.md, docs/*.txt Topic docs (auth-migration, workflow, etc.).
mcp/content/ + generated MCP bundle Downstream packaged framework knowledge. Regenerate with the repository's MCP bundler and verify no source/bundle drift whenever canonical docs or skills change.
create-orbital-app templates (sibling repository) Downstream starter copies of framework files/docs/skills. Sync intentionally and run its template drift verification whenever canonical framework surfaces change.

The rule

Editing one documentation surface is not complete until you have checked every other surface for the same content and updated the ones that need it.

This applies in both directions: change the README → check the HTML, conventions, AGENTS, and the relevant skill(s). Change a skill → check whether the rule it encodes also lives in the README/HTML/conventions/AGENTS. Etc.

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.

sync-docs is a skill published in the GitHub repository Hackbyrd/orbital-express (14 stars, last pushed 13d ago), licensed MIT. It adds 79 tokens to every session and 1,473 once invoked, about $0.0004 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.
