feature-development-workflow

A workflow guide for implementing an authorised new feature. It sorts work by complexity and sets expectations for decisions, implementation, integration, review, and completion.

In plain words
What is it for?
Use it when adding a user-visible capability, such as workspace exports or notification preferences, and when the work needs decisions, implementation evidence, review, and a completion report.
Why use it?
It helps teams apply an amount of process that matches the size and risk of a feature, while avoiding feature-specific gates for fixes, refactors, documentation, or planning.

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

feature-development-workflow 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.

The scan reads SKILL.md. This mod also ships 1 executable file (tests/test_skill_contract.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The opening of the file, as written. The whole thing — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Feature Development Workflow

Use this skill for a user-authorized request to deliver a new capability. It preserves decision, implementation, review, and completion evidence while scaling the process to the feature's actual risk and scope. It is guidance, not a runtime guard: loading this skill does not install a package, enable an integration, change settings, or create hard enforcement.

When to Use

Use when the request adds a user-visible, product, system, interface, workflow, or integration capability and the agent is expected to implement it.

Do not use for:

  • Bug fixes that restore documented or intended existing behavior.
  • Refactors with no new capability.
  • Documentation-only, test-only, formatting-only, or dependency-maintenance work.
  • Planning, research, review, troubleshooting, incident response, operations, or a question without requested feature delivery.
  • Installation, enablement, publication, deployment, or configuration changes unless that action is separately authorized.

Should trigger

  • “Add a workspace export feature with authorization rules and a CSV download.”
  • “Implement a new notification preference channel and migrate existing defaults.”
  • “Create a small user-facing toggle that enables the requested display behavior.”
  • “Build this new integration endpoint and deliver it with tests.”

Should not trigger

  • “Fix the crash when an empty CSV is uploaded.”
  • “Refactor the cache module without changing behavior.”
  • “Add API documentation and unit tests for the existing endpoint.”
  • “Research options for notification providers before we choose one.”
  • “Review this pull request for security issues.”

Ambiguous requests

A request such as “add a tiny flag” may be a feature, a bug fix, or a configuration change. Inspect the affected behavior and user intent before routing. If it is feature delivery, classify it; otherwise use the workflow appropriate to the actual task.

Invocation Design

  • Invocation mode: model-invoked after explicit package enablement.
  • Leading concept: feature implementation workflow.
  • Route only when delivery of a new capability is requested; do not use this as a catch-all engineering process.
  • Creation of this package is inert. Review it before any later installation or enablement, which requires explicit authorization.

What ships with it

2 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.

Changes

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.

feature-development-workflow is a skill published in the GitHub repository Firstp1ck/pi-coding-agent-forge (74 stars, last pushed 2d ago), licensed MIT. It adds 48 tokens to every session and 1,727 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.
