What it does
Cwng Impact Map is an agent skill from new-usemame/Calibre-Web-NextGen. Query Calibre-Web-NextGen's static cps impact map before changing a Python file, symbol, or Flask route, including confidence and blind-spot data.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Backend & APIs. It works with Flask and Python. The repository describes itself as: Community continuation of Calibre-Web-Automated. Attempting to maintain with rapid iteration. Please feel free to help out by filing Issues, Feature Requests, PRs, and chatting… The licence is GPL-3.0.
When your agent uses it
- Backend & APIs work in your project
Example prompts
- “/cwng-impact-map”
Requirements
- Python 3
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- reached_by sites, especially live_routes_reaching_target;
- downstream reaches sites;
- confidence on every cited hop; and
- blind_spots.count, the leading reasons, and relevant file:line records.
What it can do on your machine
Read from SKILL.md and the folder at commit d2844f7. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
python3git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Cwng Impact Map loads about 1.1k tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 553 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

CWNG impact map
Use this skill when a change under cps/ needs a fast, evidence-linked impact
survey. The map is a recall-oriented hint, not an authority.
From the repository root, query the most specific target available:
python3 scripts/impact_map.py query 'cps/module.py:module_level_symbol'
python3 scripts/impact_map.py query 'blueprint.endpoint'
python3 scripts/impact_map.py query '/literal/or/<converter:rule>'Use --format json when another tool will consume the result, and increase
--depth only when the direct neighborhood is insufficient.
Report these together:
reached_bysites, especiallylive_routes_reaching_target;- downstream
reachessites; - confidence on every cited hop; and
blind_spots.count, the leading reasons, and relevantfile:linerecords.
Treat exact_local_symbol, exact_import_symbol,
exact_import_module_attribute, and route_reconciled as high-confidence
static evidence. Treat class_member_coarse and attribute_name_guess as
leads that require source inspection. Never turn absence from the result into a
claim of no impact.
Before relying on a snapshot, refresh into a separate output directory. Set
TARGET to the file, symbol, or route being investigated, then run from a clean
checkout with the repo virtualenv:
python3 scripts/impact_map.py refresh \
--output-dir "$TMPDIR/impact-map" --summary "$TMPDIR/impact-map-summary.md"
python3 scripts/impact_map.py query "$TARGET" \
--map "$TMPDIR/impact-map/impact-map.json"Read the currency summary's checked commit, current/committed cps tree SHAs,
drift flags, recall number, and every miss. Compare generated_from.cps_tree_sha
with git rev-parse HEAD:cps; a different checkout SHA alone may only identify a
tooling commit. Refresh compares complete artifacts, so matching cps SHAs do not
rule out generator or oracle drift. CI publishes the same three files as the
impact-map-<checked SHA> download; a PR artifact can describe a merge candidate.
Stale snapshots and misses caused by current symbols moving or disappearing are
advisory results, including historical/current path mismatches. Contributors do
not need to commit regenerated JSON for these results. Missing historical
commits, malformed inputs, and generation errors fail refresh: resolve the
reported error before using its outputs. A failed accepted attempt removes old
currency metadata; a directory without impact-map-currency.json is incomplete.
Use separate directories for concurrent attempts and keep summary/output paths
separate from repository inputs and each other.
Refreshing the committed snapshots is a maintainer action. When that is the intended task, run:
python3 scripts/impact_map.py build
python3 scripts/impact_map.py recallShow full SKILL.md (244 more words)Show less
Two limits you must state when you use this
1. The map stops at Python. It has zero nodes outside cps/*.py — no
templates, no frontend. Measured over the last 400 cps-touching commits, 35%
also changed cps/templates/* (10%) or frontend/src/* (29%). So for roughly
a third of real changes the map structurally cannot name a consumer that exists.
If you change a serializer, a route's response shape, or anything a page renders,
the React or Jinja consumer will not appear — its absence is not evidence.
2. Recall depends entirely on what you ask about. The headline historical figure is ~80%, and that is measured on caller/consumer pairs where both ends are module-level Python symbols. Raw co-change recall across all changed symbols is 12.49%, with 37% of changed symbols getting nothing named at all. The honest range is therefore [12.5%, 80%], and which end you are at depends on your target.
You do not have to guess which: every query prints the matched module's unresolved-call count and reasons, and that number is informative rather than constant — across the 168 modules with 20 or more call sites it ranges from 0.000 to 0.870 (p10 0.262, median 0.440, p90 0.658). A module reported at 87% unresolved is telling you the answer is thin; one at 15% is telling you it is solid. Read that number every time and report it alongside the result.
Read docs/impact-map.md only when updating the generator, route oracle,
confidence taxonomy, or historical case set.
