papi-build

papi-build is a skill for Claude Code from getpapi/papi. It costs 26 tokens per session (2,029 once invoked), scanned A, original, MIT.

A build-execution guide for carrying out work through PAPI's build process. It covers branch setup, checks before implementation, and an audit after the build.

In plain words
What is it for?
Use it to start and complete an implementation task, handle already-shipped work that lacks proof, and check the result against the recorded task.
Why use it?
It reduces the risk of implementing work without confirmed scope, authority, dependencies, or completion evidence. It also distinguishes restoring missing evidence from doing a new build.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

papi-build 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 today.

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.

papi-build

For missing evidence on an existing shipped task, follow papi-plan's Already-shipped work with missing evidence route. Ordinary build completion is for actual implementation; evidence restoration preserves assignment and historical cycle and does not count a new build.

Completion authority before scheduling or building

Read the task's complete scope, structured completionAction, dependencies and assignee before proposing a task set or starting work. When scope requires final decision resolution, read the actual decision and persist its structured link through board_edit before scheduling. For action: resolve, name the remaining decision action and its current authorized resolver using the canonical decision policy. Owner, per-type and group-quorum permissions must be revalidated at plan apply and task claim; unknown authority refuses final completion. Arbitrary notes, caller-reported retry guidance and a prepared proposal are not permission or human acceptance.

Keep proposal preparation in a separate action: prepare task and retain its completed output. Hand the final action: resolve task to an authorized resolver only after explicit assignment confirmation. Do not recommend rebuilding Done/In Review preparation. An optional manual approval blocks release only when a task has an explicit dependency or typed blocker.

Reconcile board assignment with branch/PR contents. Transferring tasks or creating a branch at an already merged commit cannot remove those tasks from the original PR's historical diff. Disclose already-merged scope, preserve recipient commits and approval attribution, and use a scoped corrective change when needed; never rewrite shared main or force-push a teammate's branch to claim separation.

Cycle PR preparation

Follow the owning repository's actual branch, qualification and release contract. Read its workflow before selecting checks; PAPI maintainer scripts are not requirements for customer projects. Finish authorized metadata before qualifying the final tree once, and rerun affected checks after substantive changes. Record the exact head and evidence. Never treat local-only commits as shipped.

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.
