Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 8 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00259 | $0.04029 |
| Opus 5 | $0.00130 | $0.02014 |
| Sonnet 5 | $0.00052 | $0.00806 |
| Haiku 4.5 | $0.00026 | $0.00403 |
Grade A, and why
build-plan-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 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 — 237 lines — stays where its author put it; the contents beside it link to each section on GitHub.
build-plan-workflow — configure the /plan phase and write the claude-slack-bridge_plan wrapper
You run locally inside Claude Code (not via the Slack daemon). All clarifications go through AskUserQuestion. Do not call mcp__claude-slack-bridge__ask_on_slack from this skill — Slack is only the runtime channel for /process itself, not for setup.
This skill is the plan-workflow phase of /process-setup. By the time it returns, either:
- The user opted in, the inputs were captured, and
.claude/skills/claude-slack-bridge_plan/SKILL.mdhas been generated (status:configured); or - The user opted out at Step 1 — no helper skill is written and the caller is told the literal label
plan-workflow: skip(status:skipped).
Return values the caller needs (printed as a fenced JSON block at the end of the final reply):
status—configuredorskipped.label—plan-workflow: configuredwhen configured,plan-workflow: skipwhen skipped.has_existing_plan_process—true/false(only present when configured).existing_plan_reference— slash command or path to the user's existing plan flow (only whenhas_existing_plan_process == true).
The plan artifact is always saved to the fixed path .roadmap_features/<branch>/plan/feature_plan.md, where <branch> is the current git branch name. This is not configurable — do not ask the user where to save it.
Do not skip ahead to writing the helper skill until Step 3 has actually captured everything it needs.
Step 1 — does the user want a plan step at all?
Ask via AskUserQuestion:
Do you want a plan step in your /process workflow? (the plan step produces a markdown plan doc, saves it in the repo, opens a PR for review, and only then hands off to the next step)
Options:
- Yes, set up the plan step — continue to Step 2.
- No, help me create one — the user has no existing planning process and wants one built inline. Record
has_existing_plan_process = false,existing_plan_reference = null,existing_plan_path = null. Skip Step 2 entirely and jump straight to theplan_kindcapture described below, then continue to Step 3.
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.
- 8d ago First seen · 237 lines · 259 tokens per session scan A d22583b75150
build-plan-workflow is a skill published in the GitHub repository tomeraitz/claude-slack-bridge (33 stars, last pushed 18d ago), licensed MIT. It adds 259 tokens to every session and 4,029 once invoked, about $0.0013 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.
