Citation Gatekeeper

Citation Gatekeeper Skill

Purpose

This skill is the single authority over the thesis bibliography. No paper enters references.bib without explicit human approval. No \cite{} command references a paper that has not passed through this gatekeeper. It enforces a strict human-in-the-loop workflow for all citations, ensuring the thesis only references papers the author has actually read and deliberately chosen to include.

The Cardinal Rule

Nothing is cited without the human saying YES.

This is non-negotiable. No other skill, no automation, no convenience shortcut can bypass this rule. The human (thesis author) must explicitly approve every single paper before it can appear in the bibliography or be referenced in any .tex file.

Approval Workflow

Step 1: Review Queue

The gatekeeper reads from thesis/latex/bibliography/pending-papers.json, which is populated by the research-scout skill. Each entry has a status of pending, approved, rejected, or duplicate.

Step 2: Present to Human

Papers are presented for review, either one at a time or in batches:

Single Review Format:

--- Paper Review ---

5. [Score 3] "MetaGPT: Meta Programming for Multi-Agent Collaboration"
   Hong et al., 2024, ICLR   →  03-verwandte-arbeiten
   Decision: ___

Step 3: Process Decisions

For each paper, the human chooses one of three options:

YES — Approve

1. Paper is moved from pending-papers.json to approved-papers.json
2. A BibLaTeX entry is generated and added to references.bib
3. The paper's status in pending-papers.json is updated to approved
4. The approved_date is recorded

NO — Reject

1. The paper's status in pending-papers.json is updated to rejected
2. A rejection_reason field is added (provided by human or prompted)
3. The paper is NOT removed from pending-papers.json (audit trail)
4. The paper will not be presented again unless explicitly requested

LATER — Defer

1. The paper remains in pending-papers.json with status pending
2. No changes are made
3. The paper will appear in the next review session

File Management

• Format: Array of paper objects (see research-scout SKILL.md for schema)

approved-papers.json

• Location: thesis/latex/bibliography/approved-papers.json
• Managed by: citation-gatekeeper (sole writer)

BibLaTeX Entry Rules

• Use proper entry types: @article, @inproceedings, @book, @thesis, @online, @report
• Handle German characters with LaTeX encoding: {\"u} for ue, {\"a} for ae, {\"o} for oe, {\ss} for ss
• Use and to separate authors, with and others for long author lists
• Include doi when available
• Include url always
• Use consistent key format: [firstauthor_lastname][year][keyword] (e.g., qian2024chatdev)
• For German-language sources, add langid = {german} field

Validation Capabilities

Audit Citations by Chapter

Show all \cite{} commands in a given chapter and their approval status:

--- Citation Audit: 04-konzept ---

\cite{qian2024chatdev}     → APPROVED (2026-02-22)
\cite{wu2024autogen}       → APPROVED (2026-02-20)
\cite{TODO:mcp-spec}       → TODO PLACEHOLDER (needs real paper)
\cite{smith2023agents}     → NOT FOUND in approved list!

Find Orphan Citations

Detect \cite{} commands in .tex files that reference keys not present in references.bib:

--- Orphan Citations Found ---

04-konzept.tex:42     \cite{smith2023agents}     → Key not in references.bib
05-impl.tex:118       \cite{jones2024mcp}        → Key not in references.bib

Action: These must either be approved through the gatekeeper or removed.

Find Unused Approved Papers

Detect papers in approved-papers.json / references.bib that are never cited in any .tex file:

--- Unused Approved Papers ---

mueller2024survey    "A Survey on Agent Architectures"
  Approved: 2026-02-15
  Approved for: 03-verwandte-arbeiten
  Cited in: NOWHERE

Action: Either cite in an appropriate section or consider removing from bibliography.

Find TODO Citations

Scan all .tex files for \cite{TODO:*} placeholders:

--- TODO Citations ---

02-grundlagen.tex:28    \cite{TODO:mas-history}
  Context: "Multi-Agenten-Systeme wurden erstmals formalisiert"
  Need: Foundational MAS paper (Wooldridge, Jennings era)

04-konzept.tex:95       \cite{TODO:mcp-specification}
  Context: "Das MCP definiert einen standardisierten Kanal"
  Need: Official MCP specification or announcement

Total: 7 TODO citations remaining

Integration with Other Skills

Rules

1. No paper enters references.bib without explicit human YES -- this is absolute
2. Only this skill writes to references.bib -- no other skill, no manual edits without going through the gatekeeper
3. Only this skill writes to approved-papers.json -- single source of truth for approvals
4. Rejected papers stay in pending-papers.json -- never deleted, marked as rejected for audit trail
5. Every approval is dated -- approved_date is always recorded
6. The human can revoke approval -- remove from approved, remove from references.bib, update status
7. Regular audits are encouraged -- run orphan/unused/TODO checks before any major milestone
8. BibTeX keys are stable -- once a key is assigned and used in .tex files, it must not change
