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 | $0.00067 | $0.00546 |
| Opus 5.5 | $0.00027 | $0.00218 |
| Sonnet 5.5 | $0.00013 | $0.00109 |
| Haiku 4.5 | $0.00007 | $0.00055 |
Grade A, and why
trellis-spec-bootstrap 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 1mo 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.
This is a copy
100% identical to trellis-spec-bootstrap — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 42 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Trellis Spec Bootstrap
Use this skill to create or refresh .trellis/spec/ guidelines from the real codebase. One capable agent owns the full loop: analyze the repository, choose the spec boundaries, write the docs, and verify the result. The workflow does not depend on a specific host, CLI, or agent brand.
Workflow
- Confirm Trellis is initialized and inspect the current
.trellis/spec/tree. - Analyze the repository architecture with the best available tools: GitNexus, ABCoder, language tooling, and direct source reads.
- Decompose the spec work by package and layer only when that reflects the actual codebase.
- Fill or reshape the spec files with concrete patterns, file paths, examples, and anti-patterns from the project.
- Verify that the final specs are internally consistent and contain no template placeholders.
Reference Routing
| Need | Read |
|---|---|
| Repository architecture analysis | references/repository-analysis.md |
| Spec work decomposition and task planning | references/spec-task-planning.md |
| Writing high-signal Trellis spec files | references/spec-writing.md |
| GitNexus and ABCoder MCP setup | references/mcp-setup.md |
Operating Rules
- Treat templates as starting points, not contracts. Delete, rename, split, or add spec files when the repository calls for it.
- Prefer source-backed rules over generic advice. Every important recommendation should point at a real file or repeated local pattern.
- Keep execution single-owner by default. Optional helper agents are an implementation detail, not a requirement or user-visible dependency.
- Do not write platform-specific instructions unless the target project already standardizes on that platform.
- Do not leave placeholder text, empty headings, or copied boilerplate in
.trellis/spec/.
Done Criteria
.trellis/spec/describes the project as it exists now.- Each relevant package or layer has practical coding guidance with real examples.
- Non-applicable template sections are removed.
index.mdfiles match the final spec file set.- Any required setup or analysis assumptions are documented in the relevant spec or task notes.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

trellis-spec-bootstrap is a skill published in the GitHub repository tincopper/neeko (12 stars, last pushed yesterday), licensed Apache-2.0. It adds 67 tokens to every session and 546 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to trellis-spec-bootstrap, differing in 0 lines, and is treated as a copy.

kirocrew-app-dev
Build, package, and publish Kiro Crew external apps. Covers app.json manifests, UI components, crons, skills, lifecycle hooks, development mode, registry publishing, and common pitfalls.
goal-conductor
Own a goal too large for one session ('clear the flaky-test backlog', 'push N PRs green') end to end via the work ledger — decompose into items, one session per item, read worker status as data, verify claims with the acceptance evaluator, decide each round until done. Use when handed such a goal.
cost-efficiency-analyzer
Analyzes cost structure, cost efficiency, and expense management from P&L data. Use when the user asks about costs, expenses, COGS, operating expenses, cost ratios, cost control, spending efficiency, margin compression from cost side, or wants to understand where money is going. Also use for "are we spending too…
computer-use
Read and drive native desktop apps through the accessibility layer — list apps, snapshot a window as a numbered element tree, then click/type/scroll/drag by element index or screen coordinates. Use for a desktop app, not a web page. macOS + Windows; off unless enabled in Settings.
security-conductor
Operating procedure for the kirocrew-security-conductor agent. Use when a security conductor session is seeded, inspected or debugged. Run vulnerability discovery on one target as a supervised fleet — one auditor per attack surface, an independent verifier per finding, two human gates.
feature-demo-recording
Record a demo video of a web feature from a real browser. Two modes -- a NARRATED film where measured voiceover drives the timeline (designed slides, subtitles, punch-in camera, rendered from an HTML timeline), and a SILENT evidence clip for a PR or a QA pass. Use when the user asks to record a video, demo, or screen…
