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 | $0.00014 | $0.00302 |
| Opus 5 | $0.00007 | $0.00151 |
| Sonnet 5 | $0.00003 | $0.00060 |
| Haiku 4.5 | $0.00001 | $0.00030 |
Grade A, and why
threadlink 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 yesterday.
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.
What it actually says
/threadlink
Save decision context and optionally link a file to a thread.
Usage
/threadlink <thread> "content" [file]
Arguments
thread- Thread name (project-level, e.g., "myproject")content- Context to save (focus on the "why")file(optional) - File path to attach to the thread
Examples
/threadlink myproject "Chose JWT for stateless auth"
/threadlink api-v2 "Added rate limiting for security" src/middleware/ratelimit.ts
Instructions
When this command is invoked:
-
Use the
threadlinking_snippetMCP tool to save the content:thread_id: the thread argumentcontent: the quoted contentsource: "claude-code"
-
If a file path was provided, also use
threadlinking_attach:thread_id: the thread argumentfile_path: the file path (resolve to absolute if relative)
-
Confirm what was saved and attached.
Thread Naming
Threads should be project-level, not task-level:
- Good:
myproject,api-v2,client-acme - Bad:
fix-bug-123,refactor-auth
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.

threadlink is a command published in the GitHub repository thrialectics/threadlinking (23 stars, last pushed 1mo ago), licensed MIT. It adds 14 tokens to every session and 302 once invoked, about $0.0001 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.

checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
implement
Execute the implementation plan by processing and executing all tasks defined in tasks.md.
