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 | $0.00067 | $0.02416 |
| Opus 5 | $0.00034 | $0.01208 |
| Sonnet 5 | $0.00013 | $0.00483 |
| Haiku 4.5 | $0.00007 | $0.00242 |
Grade A, and why
build-right-execution 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 8d 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 — 232 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Build Right Execution
Use this skill after pre-execution work has produced product truth, MVP scope, operating rules, and an executable task queue.
Core rule:
Do one task.
Prove the current state.
Change narrowly.
Verify with the right evidence.
Update the tracker.
Then move to the next task.
Required Reading
- Always read
references/workflow.mdbefore acting. - Read
references/gates.mdbefore task selection, after task intake, and before advancing to another task. - Always read
references/review-and-delegation.mdbefore the review phase. Its Standards, Spec, and correctness/evidence axes apply to every task; trigger rules determine review depth and whether extra independent review is required. - Read
references/evidence-contract.mdbefore completing or updating a task. - Read
references/execution-discipline.mdafter task intake. Select its bug, feature, or refactor lane from the task's existingTypeand stated goal; do not add a mandatory task field. - Read
../build-right-engineering-principles/references/principles.mdbefore implementation or review when a task touches architecture boundaries, public APIs, package ownership, provider adapters, generated code, error semantics, tests, observability, security, or enforceable policy. - Use
assets/templates/task-template.mdwhen creating a missing task or splitting an overbroad task. - Use bundled helper scripts only through the full Bun command form shown
below. Do not rely on PATH aliases or invoke short names such as
continue-checkas shell commands. - Invoke every managed helper used as evidence as its own direct Bun shell
command. Do not chain it with
&&,;, pipes, redirects, or trailing commands; the native evidence gate binds success to that isolated invocation. - Use the state resolver before selecting a task or advancing through a queue. Report and reconcile its decision before continuing.
- The managed execution entrypoint performs setup orchestration before calling
the separate read-only
scripts/continue-check.tsresolver and provider adapter when task bindings exist. Never ask the user to invoke provider setup, validation, progress, synchronization, archive, or any provider command. - Use the execution helper for deterministic task, contract, and gate signals. Treat script output as input to judgment, not authority.
What ships with it
38 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.
- 8d ago First seen · 232 lines · 67 tokens per session scan A 96db1dc83e6c
build-right-execution is a skill published in the GitHub repository pax-k/build-right (4 stars, last pushed 1mo ago), licensed MIT. It adds 67 tokens to every session and 2,416 once invoked, about $0.0003 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 2026-08-31.
