sync-docs

sync-docs is a skill for Claude Code from juliusz-cwiakalski/agentic-delivery-os. It costs 14 tokens per session (8,778 once invoked), scanned A, original, MIT.

A guide for updating system documentation after an approved software change has been implemented. It uses the change record and its supporting plans and notes to describe what the system now does.

In plain words
What is it for?
Use it after implementing a change to update functional behavior, interfaces, system-wide requirements, and recorded decisions in documentation under doc/spec/.
Why use it?
It prevents the main specification from becoming outdated or requiring readers to search through old change folders. It also leaves out proposed details that were not actually delivered.

SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Privilege Escalation · line 677
    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
  • medium Excessive Agency · line 11
    Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.
    Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.

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 9d 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 — 869 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a world-class technical documentation writer that ensures current system specification is up to date after change implementation.

Success: A reader can understand the current system from doc/spec/** without needing the change folder.

<discovery_rules> Locate change folder: search doc/changes/**/*--<workItemRef>--*/ If not found, search: doc/changes/**/chg-<workItemRef>-spec.md Spec file: chg-<workItemRef>-spec.md; derive slug & change.type from frontmatter. Plan file: chg-<workItemRef>-plan.md Folder pattern: doc/changes/YYYY-MM/YYYY-MM-DD--<workItemRef>--<slug>/ </discovery_rules>

<source_extraction> From the change documentation folder for this change (at minimum the change spec and implementation plan, and when present the per-change test plan, execution notes, and examples.json):

  • Functional capabilities (F-#) actually delivered (cross-check against acceptance criteria evidence AC-* PASSED lines).
  • Interfaces (API-#, EVT-#, DM-#) with finalized contracts (omit speculative ones lacking acceptance evidence).
  • NFRs (NFR-#) that modify or add system-wide thresholds.
  • Decision log entries (DEC-#) that affect enduring architecture (copy into ADR if not already recorded; ensure ADR references present).
  • Data model changes (DM-#) confirmed by implementation steps.
  • Telemetry additions (logs, metrics) that become part of observability baseline.
  • Security/privacy changes.

<target_updates> System documentation areas potentially updated:

  1. /doc/spec/features/ — Each enduring behavior mapped to a feature spec file (create or update). File naming: feature-<slug-or-domain>-<short>.md.
  2. /doc/spec/api/ — Update endpoint descriptions. Synchronize with OpenAPI under /doc/contracts/rest/openapi.yaml.
  3. /doc/spec/nonfunctional.md — Merge new/updated NFR thresholds.
  4. /doc/contracts/rest/openapi.yaml & /doc/contracts/events/asyncapi.yaml — Add/modify operations/events.
  5. /doc/contracts/events/schemas/ — Add new payload schema files if events created.
  6. /doc/domain/events-catalog.md — Insert or update domain event descriptions.
  7. /doc/quality/test-specs/ — Ensure test spec entries exist for each acceptance criterion referencing workItemRef.
  8. Cross-links: Update front matter with links.related_changes: ["<workItemRef>"] and link ADRs.

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.
