Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00040 | $0.03228 |
| Opus 5 | $0.00020 | $0.01614 |
| Sonnet 5 | $0.00008 | $0.00646 |
| Haiku 4.5 | $0.00004 | $0.00323 |
Grade A, and why
synthesis 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.

Tapestry Synthesis
Analyze a stored Tapestry artifact: $ARGUMENTS
When to use this skill
Use this skill when:
- A user wants interpretation or analysis of already-ingested content
- You need to consolidate multiple sources into research notes
- The user asks for synthesis, insights, or higher-level understanding
- You need to organize ingested content into the knowledge base hierarchy
- The deterministic ingest is complete and model-based reasoning is needed
Overview
This skill is the workflow layer for model-eligible reasoning.
Use it after deterministic ingest has already produced:
- a capture JSON file
- a normalized feed JSON file
- a Markdown knowledge-base note
- a structured handoff payload describing the recommended analysis
The package runtime does not call any model APIs directly. This skill owns the interpretation step.
This skill is also responsible for maintaining the book-like knowledge base under knowledge-base/.
Important: The synthesis mode configuration controls when this skill should be invoked:
auto: Agent evaluates note accumulation and decides whether to merge (intelligent, load-based)manual: Only runs when explicitly requested by userbatch: Runs after multiple ingests to process all at oncedeterministic: Runs automatically after every single ingest (high overhead)
See config/tapestry.config.json for current mode setting.
Workflow
- Identify the target:
- if the user gave a stored note path, use it directly
- if the user gave a URL and it has not been ingested yet, run
$tapestry-ingestfirst
- IMPORTANT: Change to the project root directory before running the script:
cd /path/to/your/tapestry/project
python synthesis/_scripts/load_context.py \
"$ARGUMENTS"
Or use the --project-root flag:
python synthesis/_scripts/load_context.py \
--project-root /path/to/your/tapestry/project \
"$ARGUMENTS"
- Read the returned handoff payload carefully:
digestis the deterministic baselineanalysis.skill,analysis.instructions, andanalysis.deliverabledescribe the intended workflownote_text,feed_payload, andcapture_payloadare the factual source materials- Identify the language by reading the content naturally (title, body, comments)
- Ensure the book hierarchy exists:

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.
- 9d ago First seen · 321 lines · 40 tokens per session scan A 41c73268525a
synthesis is a skill published in the GitHub repository NatsuFox/Tapestry (64 stars, last pushed 4mo ago), licensed MIT. It adds 40 tokens to every session and 3,228 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
