Citation Fixer Skill
Convention: see conventions/quality.md for
the canonical citation format every fix should match.
>
Output rule: all links MUST be deterministic (built from API data,
not composed by LLM). See _output-rules.md.
Contract
This skill guarantees:
- Every brain page is scanned for citation compliance.
- Missing citations are flagged with specific location.
- Malformed citations are fixed to match the standard format.
- (v0.25.1) Tweet / post references without URLs are resolved via
X API and patched with deterministic https://x.com/<handle>/status/<id> links.
- Results reported with counts (scanned, fixed, remaining).
Phases
1. Scan pages. List pages and read each one, checking for inline [Source: ...] citations. 2. Identify issues:
- Facts without any citation
- Citations missing date
- Citations missing source type
- Citations with wrong format
- (v0.25.1) Tweet references without
x.comURLs
3. Fix format issues. Rewrite malformed citations to match conventions/quality.md. 4. (v0.25.1) Resolve tweet references via the X API integration. 5. Report results. Count: pages scanned, citations found, issues fixed, tweets resolved, remaining gaps.
Tweet resolution pipeline (v0.25.1 extension)
For each broken tweet reference, follow this chain. The actual API call goes through whatever X integration the host has configured (typical shape: a recipe under recipes/x-api/ with handle / search-all endpoints).
Step 1: Identify broken references
Scan the page for patterns that indicate tweet references without URLs:
- Contains words like
tweeted,posted,said on X,RT,retweet,
X post
- Contains quoted text that looks like a tweet (short, punchy, often
starts with a quote)
- Has
[Source: ... X/Twitter ...]without anx.comURL - References engagement metrics (likes, impressions) without a link
Step 2: Extract searchable content
From each broken reference, extract:
- The handle (if mentioned:
@<username>) - The quoted text (if available)
- The approximate date (often present in surrounding timeline entries)
Step 3: Search for the actual tweet
Use the host's X API integration. Query patterns:
# Handle + quoted text:
from:<handle> "<exact quote fragment>"
# Quoted text only:
"<exact quote fragment>"
# Original of a retweet:
"<exact quote>" -is:retweetStep 4: Verify and extract metadata
Once a candidate is found:
- Confirm the text matches the quoted fragment.
- Pull the tweet id, author handle, engagement metrics (likes / RTs /
impressions).
- Construct the URL:
https://x.com/<handle>/status/<tweet_id>.
Step 5: Patch the brain page
Replace the broken citation with a proper one:
Before:
"<quote fragment>" [Source: <some hand-wavy attribution>]After:
"<full verified quote>" — <N> likes, <N> RTs, <N> impressions
[Source: [X/<handle>, YYYY-MM-DD](https://x.com/<handle>/status/<tweet_id>)]Batch mode
When sweeping many pages:
Find candidate pages
# Pages mentioning tweets but with no x.com links
for f in $(find . -name "*.md" -not -path "./node_modules/*"); do
refs=$(grep -ci "tweet\|posted\|x post\|RT\|retweet\|said on X" "$f")
links=$(grep -c "x.com/.*/status/" "$f")
if [ "$refs" -gt 2 ] && [ "$links" -eq 0 ]; then
echo "$f"
fi
donePriority order
1. Recently created / updated pages — fresh broken refs are easiest to resolve while context is fresh. 2. High-traffic pages (frequent reads / writes from other skills). 3. Everything else — bulk cleanup over time.
Rate limiting
- X API: respect the host's tier limits; don't hammer.
- Target ~50 pages per batch run.
- 1-3 API calls per page (search + verify).
- Batch-commit every 10-20 pages so a partial failure doesn't lose
progress.
Output format
Citation Audit Report
=====================
Pages scanned: N
Citations found: N
Issues fixed: N
Tweet links resolved: N
Remaining gaps: N (pages with uncitable facts)Anti-Patterns
- ❌ Inventing citations for facts that have no source. Flag them.
- ❌ Removing facts that lack citations (flag them; don't delete).
- ❌ Fixing citations without reading the full page context.
- ❌ Batch-fixing without checking quality on a sample first
(see conventions/test-before-bulk.md).
- ❌ Composing tweet URLs by guessing the tweet id. Always go through
the X API; deterministic links only.
Integration
This skill can be called:
- Manually — "fix citations on this page"
- As a batch cron — weekly sweep of pages with broken refs
- By other skills —
enrichormedia-ingestcan call citation-fixer
before commit to validate output
Metrics
If running as a recurring batch, track state in a small JSON file under ~/.gbrain/citation-fixer-state.json:

"pages_scanned": 0,
"citations_fixed": 0,
