Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00052 | $0.03090 |
| Opus 5 | $0.00026 | $0.01545 |
| Sonnet 5 | $0.00010 | $0.00618 |
| Haiku 4.5 | $0.00005 | $0.00309 |
Grade A, and why
init-workspace 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 — 200 lines — stays where its author put it; the contents beside it link to each section on GitHub.
init-workspace — the interview (M7)
Human-only: the user's consent point for the whole workspace. Every command
below is ${CLAUDE_PLUGIN_ROOT}/bin/harness <verb> … — always the full
path; a bare harness is not on PATH, and shell variables set in one Bash
call do not persist to the next. Re-running refreshes one section at a
time (init-section), never a full-nuke.
0 · Environment bootstrap (do this FIRST)
Resolve the plugin root. Under native Qwen Code (no Claude-plugin
conversion), ${CLAUDE_PLUGIN_ROOT} is not exported until step 6 writes
.qwen/settings.json, and even then only next session. Each Bash call is a
fresh subprocess (an export won't persist), so the probe prints the
resolved path for you to substitute textually; if the var is already set
(Claude Code, converted install) the probe passes it through unchanged:
Folder-trust caveat (Qwen Code): project-level .qwen/settings.json is
silently ignored unless the folder is trusted (trusted-folders is OFF by
default, measured on 0.22.2) — the CLAUDE_PLUGIN_ROOT export and the
permission mirror don't apply, so subagents hit the prompts the allowlist
was meant to pre-clear. The pipeline's hooks are unaffected (they ship with
the extension). Remedy: trust the folder (Qwen /permissions → Trust this
folder, then restart) or export CLAUDE_PLUGIN_ROOT in the launching shell.
# Resolve the plugin root and print it (native Qwen first-run fallback)
R="${CLAUDE_PLUGIN_ROOT:-}"
[ -z "$R" ] && for d in "$HOME/.qwen/extensions/ai-sdlc-harness/bin/harness" \
"$HOME/.qwen/extensions/ai-sdlc-harness/.qwen-extension-install.json"; do
[ -e "$d" ] && { case "$d" in *install.json) R=$(python3 -c \
"import json,sys;print(json.load(open(sys.argv[1])).get('source',''))" "$d");; \
*) R=$(dirname "$(dirname "$d")");; esac; [ -x "$R/bin/harness" ] && break; }; done
[ -x "$R/bin/harness" ] || { echo "ERROR: set CLAUDE_PLUGIN_ROOT to the dir with bin/harness" >&2; exit 1; }
echo "PLUGIN_ROOT=$R"
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.

init-workspace is a skill published in the GitHub repository MostAshraf/ai-sdlc-harness (18 stars, last pushed 11d ago), licensed MIT. It adds 52 tokens to every session and 3,090 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 2026-08-30.
