aigd-sync

aigd-sync is a skill for Claude Code, Codex from ProdaZhang/aigd. It costs 110 tokens per session (1,127 once invoked), scanned A, original, MIT.

A game-design integration skill that updates the project's shared specifications after an individual system is finalized. It keeps the global design, combined HTML prototype, and implementation guide aligned with each completed system.

In plain words
What is it for?
Use it after handing off a system to merge its results into the global specification, update the integrated prototype and implementation guide, and record cross-system acceptance checks.
Why use it?
It prevents changes in one game system from leaving the overall design or prototype outdated. It also tracks downstream effects and consolidates shared values such as names, numbers, and units.

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

aigd-sync 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.

AIGD · sync (sync-back integration) [minimal skeleton]

Package contract: install the whole aigd package (the orchestrator aigd/+references/ and the 6 sub-skills (including aigd-ui-capture) placed at the same level in this environment's skills directory, following the host agent, e.g. Claude Code's .claude/skills/), don't copy this skill alone — this package's sub-skills rely on aigd/ at the same level to fetch the methodology, copying it alone breaks the link.

Positioning

Cross-cutting action (not a linear "step 5"): triggered after every system's handoff, a continuous / milestone-style sync-back. Writes each single system's results back to the project layer, keeping the spine consistent with the whole; manages "downstream impact".

Read / produce / write back

  • Read: the manifest (full), each system's status, the project charter.
  • Produce / change:
    • Global-spec consolidation (enums / number ranges / units deduplicated and aligned).
    • spec/integration-acceptance.md (land the results of the "integration check" below into cross-system acceptance; the implementation master guide points to it).
    • Overall prototype (integration demo) — a single html file, placed where the project charter "directory layout" specifies (engineering layout → docs/prototypes/).
    • impl-overview.md (handoff-package entry point: the start-here for downstream AI).
  • Write back: ① shared item changed → per "recipe 4" reverse-look-up in two categories (point-to-point → table A "depended-on-by (downstream)" / broadcast-type → table C "referenced shared source of truth") → mark affected already-finalized systems Recheck (record in table D); ② recheck passed → that system Recheck → Final, refresh table D's finalization time (= this recheck's confirmation time) — this is the only exit from the Recheck state; not handling it leaves that state hanging forever.

Recipe

  1. After a system is finalized: absorb its enums / number ranges into the global spec.
  2. Merge that system into the overall prototype (integration demo).
  3. Refresh the implementation master guide (system list / build order / contract locations / acceptance entry).
  4. Run downstream impact, in two categories (each reverse-looks-up a different column):
    • Point-to-point system edge (one system's output consumed by several others) changed → reverse-look-up table A "depended-on-by (downstream)", mark those few downstream Recheck (record in table D).
    • Broadcast-type shared source of truth (enums / text structure / id namespace, see manifest table F) changed → backward-compatible (pure append) needs no recheck; breaking change → reverse-look-up table C "referenced shared source of truth" to find the systems that listed it (broadcast-type sources aren't in table A "depended-on-by") → mark those systems Recheck in table D, don't blow up the whole table.
  5. Recheck the Recheck systems: verify whether their references to the "changed shared item" still hold → if they hold, status back to Final, refresh table D; if not, bounce (back to iterate/concept, and per the bounce rules cascade to its downstream again).

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.
