What is purge-initiative-artifacts-app?

A procedure for deleting temporary engineering documents for one completed initiative while preserving source code, tests, accepted architecture decisions, and other protected records. An initiative is a defined piece of product or engineering work identified by an INIT-* code.

Use it to clean up feasibility reports, technical reviews, implementation plans, wave reports, verification reports, learning notes, and still-draft architecture records after an initiative closes.

It removes working papers that are no longer needed while limiting deletion to an approved list and a single initiative. Git history remains available as an archive.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00106	$0.01502
Opus 5	$0.00053	$0.00751
Sonnet 5	$0.00021	$0.00300
Haiku 4.5	$0.00011	$0.00150

Security

Grade A, and why

purge-initiative-artifacts-app 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 4d 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 — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purge initiative artifacts (app)

Lane: engineering / app repo (profile: development).

Delete PURGE-set files under the app repo for one initiative. Do not delete durable KEEP roots. Git history remains the archive.

This skill is independent of meta/PM purge. Do not require, invoke, or document /purge-initiative-artifacts-meta as a prerequisite or next step — orchestration order lives only in pinned workflow.yaml.

Normative allowlist / refuse: prayog-skills/references/artifact-write-contract.md.

NON-NEGOTIABLE

Resolve layout from .harness/profile.yaml or references/layout-defaults.md.
Require initiative id INIT-*. Scope deletes to that initiative only.
Delete only the app PURGE allowlist when present:
- {reports_dir}/Initiative-Feasibility-Report-{INIT}.md
- {reports_dir}/Technical-Review-{INIT}.md
- {reports_dir}/Implementation-Plan-{INIT}.md
- {reports_dir}/Pre-Implement-{INIT}-W*.md
- {reports_dir}/Wave-Execution-{INIT}-W*.md
- {reports_dir}/Live-Verify-{INIT}-W*.md
- {reports_dir}/Ground-Report-*-W*.md for this initiative/spec
- {reports_dir}/Learning-Extract-{INIT}-W*.md
- {adr_dir}/adr-*-*.md that are still Draft (not Accepted)
Refuse (never delete): {product_spec_dir}/INIT-*.md for this initiative; Accepted ADRs; anything under source_roots, unit_tests_dir, live_verify_dir scripts, fixtures_dir packs; .harness/; product source; {as_built_dir}/implementation-status.md (index) and {as_built_dir}/Implementation-Status-{INIT}.md (this initiative's detail) — both KEEP, never on the PURGE allowlist.
Idempotent: missing allowlisted files → ok. Empty delete set → still pass with rationale in handoff signals.
Work on the initiative-closure head cut from integration (develop) when bound; do not invent a branch. Fill handoff.forge for commit_workspace when pin requires commit. When pin next is an open_draft_pr external-action (eng closure PR), fill title/body from signals without creating a reports/ file (see output template).
No Gateflow authorize-before-delete. No merge. Never apply *-lgtm.
No report file. Do not write Purge-*.md (or any new artifact) under {reports_dir}. Goal achieved = handoff envelope (+ baton when bound) with delete/refuse lists in signals. Chat may repeat the same summary.
Dual-walker: same procedure for human /purge-initiative-artifacts-app and Gateflow orch.

What ships with it

7 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.

purge-initiative-artifacts-app is a skill published in the GitHub repository drivestream-lab/prayog-skills (2 stars, last pushed 5d ago), licensed MIT. It adds 106 tokens to every session and 1,502 once invoked, about $0.0005 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.
