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.

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 | $0.00051 | $0.03654 |
| Opus 5 | $0.00026 | $0.01827 |
| Sonnet 5 | $0.00010 | $0.00731 |
| Haiku 4.5 | $0.00005 | $0.00365 |
Grade A, and why
backstage-techdocs 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Backstage TechDocs
Wire the docs-like-code pipeline correctly, and tell apart the four places it breaks: the entity annotation, the mkdocs source, the generator, and the publisher.
Preconditions
- Release line from
backstage.json; TechDocs packages resolved withyarn why @backstage/plugin-techdocs-backendandyarn why @techdocs/cli. - Backend generation:
backend.add(import('@backstage/plugin-techdocs-backend'))inpackages/backend/src/index.tsis the new backend system; acreateRouterinpackages/backend/src/plugins/techdocs.tsis legacy — migrate it (backstage-plugin-migrate) before adding a build-strategy module. - Frontend generation: NFS (default since v1.49) registers TechDocs and its addon modules as
featuresfrom/alphaexports; legacy hasTechDocsIndexPage/TechDocsReaderPageinside<FlatRoutes>and anEntityTechdocsContenttab inEntityPage.tsx. - The effective merged config, not
app-config.yamlalone:yarn backstage-cli config:print --lax. Production almost always overridestechdocs.*inapp-config.production.yaml. - Whether the runtime has Docker (for
runIn: docker) or Python withmkdocs-techdocs-core(forrunIn: local).
Procedure
- Read the triple before anything else.
techdocs.builder,techdocs.generator.runIn,techdocs.publisher.typedetermine which failures are even possible.builder: 'local'— the backend generates and publishes on demand when a user opens the docs tab. Out-of-the-box default.builder: 'external'— the backend only reads pre-built docs from storage. It will never build, no matter what is wrong with the source. This is the recommended production architecture.publisher.type:'local'|'awsS3'|'googleGcs'|'azureBlobStorage'.localwrites totechdocs.publisher.local.publishDirectory, defaulting to astaticdir at the backend root — pod-local, lost on restart, and invisible to sibling replicas.
- Check the entity side second. In
catalog-info.yaml,metadata.annotations['backstage.io/techdocs-ref']is the only thing that points TechDocs at source:dir:.— docs live besidecatalog-info.yaml;dir:./sub-folderfor a subdirectory.url:https://github.com/org/repo/tree/<branch>(GitLaburl:https://host/org/repo, Bitbucket.../src/<branch>, Azure.../_git/<repo>). Suffix a subdirectory path with/so relative paths resolve.- An entity with no
techdocs-refgets no docs tab content. A monorepo child that should show a parent's docs usesbackstage.io/techdocs-entity: <kind>:<namespace>/<name>(plusbackstage.io/techdocs-entity-pathto deep-link), not a duplicatetechdocs-ref. - A
url:target must be reachable by anintegrations.*credential in the backend's config, not just yours (backstage-repo-discovery).
- Check the source layout third. At the root of whatever
techdocs-refresolves to:mkdocs.yml(ormkdocs.yaml) plus adocs/directory containing at minimumindex.md. Minimum config:
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.

backstage-techdocs is a skill published in the GitHub repository bendaamerahmed/backstage-idp-plugin (1 stars, last pushed 28d ago), licensed MIT. It adds 51 tokens to every session and 3,654 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 2026-08-31.
