iflow-build

iflow-build is a skill for Claude Code, Codex, Cursor from jepegit/issue-flow. It costs 18 tokens per session (2,454 once invoked), scanned A, original, MIT.

A workflow skill for implementing a confirmed plan for the current issue, following the project's documented coding conventions. An issue is a tracked piece of work, and a plan describes how to complete it.

In plain words
What is it for?
It helps carry out the planned code changes for an issue while respecting repository guidance and the project's required workflow.
Why use it?
It keeps implementation aligned with existing project rules and the decisions already made during planning. It separates coding work from planning the solution.

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

iflow-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 3d 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 — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.

issue-flow — issue build (/iflow-build)

Follow this skill to begin implementation from issue notes and project rules. Planning itself lives in /iflow-plan; this skill is implementation-only. Stay aligned with .cursor/rules/issueflow-rules.mdc when present.

Invoke: type iflow build in chat, or /iflow-build from the slash menu (iflow-build also works).

MODEL & EXECUTION DIRECTIVE

Profile: reasoning — Prioritize deep thinking and careful trade-offs over speed or token economy.

In Cursor: switch to a thinking-capable model before invoking this step (not Auto-only).

Keep scope tight to what this step requires.

Resolve project root (multi-root workspaces)

Before any git, gh, or .issueflows/ path operation in this workflow:

Resolution order (stop when unambiguous):

  1. Explicit hints in slash input — root:<path>, repo:<folder-basename> (directory name, e.g. cellpy-core), or repo:owner/name.
  2. CLI fast pathissue-flow agent resolve [-C <start>] [--from-file <active-file>] [--json]. Use the returned project_root and repo; pass -C <project_root> to other issue-flow agent … subcommands. When the answer came from the workspace registry, the payload sets resolved_via_workspace_default: true.
  3. Branch context — exactly one workspace repo whose branch matches ^\d+- → that root.
  4. Single scaffold — exactly one .issueflows/ tree visible in the workspace → that root.
  5. Workspace default — an issueflow-workspace.toml at the workspace root (created with issue-flow workspace init) may name a default member repo; use it when no scaffold matched above. Tell the user the default was used.
  6. Ambiguousstop and ask; never guess between sibling repos.

After resolution, treat the result as <project_root> and <owner/repo>:

  • Git: git -C <project_root> … (or issue-flow agent … -C <project_root> for supported ops).
  • GitHub: pass an explicit repo on every gh call — never rely on gh's implicit cwd default. For most commands use --repo <owner/repo>; exception: gh repo view takes the repo as a positional arg (gh repo view <owner/repo> …) and rejects --repo.
  • Paths: all .issueflows/… paths are under <project_root>.

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.

iflow-build is a skill published in the GitHub repository jepegit/issue-flow (4 stars, last pushed 20d ago), licensed MIT. It adds 18 tokens to every session and 2,454 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 2026-08-31.
