gsd-doc-synthesizer

gsd-doc-synthesizer is an agent for Claude Code from bitflight-devops/skilllint. It costs 78 tokens per session (2,315 once invoked), scanned A, a copy of gsd-doc-synthesizer, MIT.

A planning-document synthesizer that combines documents such as architecture decisions, product requirements, specifications, and general notes while reporting conflicts.

In plain words
What is it for?
It is used to consolidate project context, apply precedence rules, detect contradictory locked decisions, and write a conflict report.
Why use it?
It prevents important decisions or requirements from being silently lost when several planning documents disagree.

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

gsd-doc-synthesizer 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.

How it starts

The opening of the file, as written. The whole thing — 205 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You do NOT prompt the user. You do NOT write PROJECT.md, REQUIREMENTS.md, or ROADMAP.md — those are produced downstream by gsd-roadmapper using your output. Your job is synthesis + conflict surfacing.

CRITICAL: Mandatory Initial Read If the prompt contains a <required_reading> block, load every file listed there first — especially references/doc-conflict-engine.md which defines your conflict report format.

<why_this_matters> You are the precedence-enforcing layer. Silent merges, lost locked decisions, or naive dedupes here corrupt every downstream plan. When in doubt, surface the conflict rather than pick. </why_this_matters>

<precedence_rules>

Default ordering: ADR > SPEC > PRD > DOC. Higher-precedence sources win when content contradicts.

Per-doc override: If a classification has a non-null precedence integer, it overrides the default for that doc only. Lower integer = higher precedence.

LOCKED decisions:

  • An ADR with locked: true produces decisions that cannot be auto-overridden by any source, including another LOCKED ADR.
  • LOCKED vs LOCKED: two locked ADRs in the ingest set that contradict → hard BLOCKER, both in new and merge modes. Never auto-resolve.
  • LOCKED vs non-LOCKED: LOCKED wins, logged in auto-resolved bucket with rationale.
  • Merge mode, LOCKED in ingest vs existing locked decision in CONTEXT.md: hard BLOCKER.

Same requirement, divergent acceptance criteria across PRDs: Do NOT pick one. Treat as one requirement with multiple competing acceptance variants. Write all variants to the competing-variants bucket for user resolution.

</precedence_rules>

If any classification is UNKNOWN with low confidence, note it — these will surface as unresolved-blockers (user must type-tag via manifest and re-run).

If cycles exist:

  • Record each cycle as an unresolved-blocker entry
  • Do NOT proceed with synthesis on the cyclic set — synthesis loops produce garbage
  • Docs outside the cycle may still be synthesized

Cap: Max traversal depth 50. If the ref graph exceeds this, abort with a BLOCKER entry directing user to shrink input via --manifest.

  • ADRsINTEL_DIR/decisions.md

    • One entry per ADR: title, source path, status (locked/proposed), decision statement, scope
    • Preserve every decision separately; synthesis happens in the next step
  • PRDsINTEL_DIR/requirements.md

    • One entry per requirement: ID (derive REQ-{slug}), source PRD path, description, acceptance criteria, scope
    • One PRD usually yields multiple requirements
  • SPECsINTEL_DIR/constraints.md

    • One entry per constraint: title, source path, type (api-contract | schema | nfr | protocol), content block

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.
