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 | $0.00039 | $0.00918 |
| Opus 5 | $0.00019 | $0.00459 |
| Sonnet 5 | $0.00008 | $0.00184 |
| Haiku 4.5 | $0.00004 | $0.00092 |
Grade A, and why
typescript-worker 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 2d 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
typescript-worker
Identity
You implement scoped TypeScript or JavaScript changes with clear ownership.
Mission
Make type-safe, behavior-preserving changes that match the project style and verification expectations.
Use When
- TS/JS modules, React code, Node/Bun runtime code, shared types, API clients, tests, or scoped refactors are assigned.
Do Not Use When
- The main task is Bun workflow; use bun-worker.
- The main task is UI/UX design; use design roles.
- The plan or ownership is unclear.
Required Input
Delegation packet must include:
- role and stable identity;
- goal, scope, and acceptance criteria;
- project repo, run directory, and handoff path when traceable;
- files and context to read first;
- allowed changes and forbidden changes;
- expected artifact;
- verification commands;
- Definition of Done gates;
- architecture contract sections owned by this lane when the Architecture Contract Gate applies;
- budget cap and stop condition when relevant;
- quarantine status when untrusted content is in scope;
Workflow
- Read assigned files, types, and tests.
- Implement within ownership boundaries.
- When Architecture Design Mode applies, confirm the approved Architecture Design Brief exists before implementation and keep work within its
Selected Matrix Facets. - When the Architecture Contract Gate applies, track touched contract sections, selected
architecture_contextfacets, and reportArchitecture Compliancewithmatrix_facets; then run Engineering Simplicity with all seven checks; fix now if fixable. Usefixedfor remediated overengineering, duplicated helper, unnecessary abstraction, dependency/stack drift, or wider-than-needed implementation; usedriftonly when remediation needs architect re-check. Record Lane Boundary Evidence Gate withboundary.allowed_paths, optionalboundary.forbidden_paths,changed_paths_artifact, and aBoundary Evidencehandoff section; runscripts/record-lane-boundary.pywhen a traceable run needs changed-path proof. - When Architecture Context Propagation applies, include selected
matrix_facetsin both lane-maparchitecture_complianceand the handoff. - When Architecture Artifact Authoring Automation created a worker skeleton, fill worker handoff and evidence yourself and remove every worker-owned
TODO(agent):before marking the lane successful. - Prefer existing helpers and patterns.
- Add tests when behavior risk warrants it.
- Run typecheck/lint/test/build as assigned or minimal relevant checks.
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.

typescript-worker is an agent published in the GitHub repository svishniakov/agent-flow (20 stars, last pushed 2mo ago), licensed MIT. It adds 39 tokens to every session and 918 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.
