Project -> global boundary: - Split the reusability gate: NonReusableReason (machine-specific: absolute home paths) drops suggestions entirely; ProjectScopeReason (project-specific: repo-rooted ./scripts/... invocations, hardcoded release version tags) redirects them to ./.odek/skills instead of the global dir. Redirect is refused when the project dir resolves to the same location as the global dir (odek run from $HOME). - Confine micro-curation (MicroCuration/RunAutoCurate) to skills physically stored under the global dir via Skill.Source.Dir, so a project skill can never be merged into a global skill or deleted by the curator (fail-closed on empty source). - Wire projectDir through RunAutoSaveLoop and the CLI/serve/telegram call sites; reload + notifier events account for ProjectSaved.

Full reference: [docs/SECU - **Audit log** (`cmd/odek/audit.go` + `internal/session/audit.go`) — every `wrapUntrusted` call records source + content-hash + turn into `/audit/.json`. After each turn a divergence heuristic flags `suspicious_divergence=true` when the agent ingested untrusted content AND its actions or final response reference resources that either did not appear in the user's message or were introduced by the untrusted content itself (closing response-only exfiltration and reused-resource injection bypasses). Inspect with `odek audit ` / `odek audit --list`. - **Memory taint** (`internal/memory/provenance.go`) — `EpisodeProvenance` tracks Untrusted/Sources/UserApproved. Tainted episodes are stored but `Search()` filters them out, so a one-shot injection cannot persist via the episode pipeline. User must explicitly promote. - **Skill provenance gate** (`internal/skills/loader.go` + `cache.go` + `tools.go`) — `Skill.Provenance{Untrusted, Sources, NeedsReview}`. NeedsReview skills pin to Lazy regardless of `auto_load` and are excluded from lazy trigger matching (the matchers in `reloadLocked` are built only from promotable skills), so a flagged skill cannot be injected into context on a keyword match. Skills scanned from the project-local `./.odek/skills/` directory are distrusted like `./odek.json`: they are forced to `NeedsReview` with `"project"` in `Sources` until promoted. The auto-save path declines tainted suggestions by default. Agent-created skills via `skill_save` and patched skills via `skill_patch` are forced to `Untrusted` + `NeedsReview`, and `skill_patch` refuses edits that touch the YAML frontmatter, blocking an injected agent from flipping `auto_load` or clearing `needs_review`. All skill-body scans (load, save, patch, suggestion) go through `guard.ScanContentWithScope`, so the fast local rule scan runs even when the `skills` guard scope or the guard itself is disabled; the sidecar second opinion only runs when the scope is enabled (default: on). Taint derives from `memory.ToolCallTaints`, whose always-external set covers `browser` / `http_batch` / `transcribe` / `session_search` / `web_search` / `vision` / `delegate_tasks` (`shell` is deliberately excluded as the primary work tool). `odek skill promote --force` clears the flag after explicit user review. +- **Skill scope gates** (`internal/skills/selfimprove.go` + `curator.go`) — the auto-save pipeline classifies every suggestion by scope before writing. Machine-specific suggestions (`NonReusableReason`: absolute home-directory paths) are dropped entirely. Project-specific suggestions (`ProjectScopeReason`: repo-rooted `./scripts/...` invocations, hardcoded release version tags) are redirected to the project skills dir `./.odek/skills` — project-related skills are never promoted to the global `~/.odek/skills`, and the redirect is refused (suggestion dropped) when the project dir resolves to the same location as the global dir (e.g. odek run from `$HOME`). Post-session micro-curation (`MicroCuration` / `RunAutoCurate` / `ExecuteMicroCuration`) is confined via `Skill.Source.Dir` to skills physically stored under the global dir, so a project skill can never be merged into a global skill or deleted by the curator. `DetectCorrection` additionally requires explicit correction phrases plus a shared lead verb between the corrected commands, and derived trigger keywords filter shell operators, flags, and version fragments — together these suppress the "garbage skill" class (one-off commands saved as reusable knowledge). - **Sub-agent damage cap** (`cmd/odek/subagent.go::applySubagentTrust`) — `delegate_tasks` carries `trust_level` + `max_risk`. The mutated `DangerousConfig` is passed into the sub-agent's `odek.Config` so the engine enforces the cap. Untrusted ⇒ NonInteractive=deny, Destructive/CodeExec/Install/SystemWrite/NetworkEgress/Unknown/Blocked all forced to Deny. `max_risk` ⇒ everything above cap forced to Deny. MCP tools are not loaded into untrusted sub-agents, because the MCP `ToolAdapter` does not perform its own danger check and would otherwise bypass the cap. - **FD-based API key handoff** (`cmd/odek/subagent_key.go`) — parent writes key to a 0600 tempfile, immediately `unlink()`s, passes the FD via `cmd.ExtraFiles`. Sub-agent reads from `$ODEK_API_KEY_FD` and closes. Key never in `/proc//environ`. - **Approver friction** (`internal/danger/approver.go`, `cmd/odek/wsapprover.go`, `cmd/odek/shell.go`, `cmd/odek/perf_tools.go`) — both TTYApprover and WSApprover engage friction mode after 3 approvals of the same class in 60s: require typing literal `approve`, 1.5s pause. Trust-class shortcut disabled for `destructive` + `blocked` regardless. CLI `shell`/`parallel_shell` reuse a single TTYApprover instance per process so the counter and trust cache persist across prompts. diff --git a/cmd/odek/main.go b/cmd/odek/main.go index 18d2ef6..57cbffa 100644 --- a/cmd/odek/main.go +++ b/cmd/odek/main.go @@ -2011,7 +2011,7 @@ func runLearnLoop(messages []llm.Message, sm *skills.SkillManager, llmClient ski if skillsCfg.Verbose { verbose = os.Stderr } - if skills.RunAutoSaveLoop(filtered, userDir, sm, llmClient, skillsCfg, g, guardCfg, verbose) { + if skills.RunAutoSaveLoop(filtered, userDir, skills.ProjectSkillsDir(), sm, llmClient, skillsCfg, g, guardCfg, verbose) { return } diff --git a/cmd/odek/serve.go b/cmd/odek/serve.go index f62d560..2f7e9a7 100644 --- a/cmd/odek/serve.go +++ b/cmd/odek/serve.go @@ -1211,13 +1211,13 @@ func handlePrompt( resolved.Skills.Curation.SkipThreshold, resolved.Skills.Curation.SkipResetDays) _ = skipped if resolved.Skills.AutoSave.Enabled { - result := skills.AutoSaveSuggestions(filtered, userDir, resolved.Skills, g, resolved.Guard, false) + result := skills.AutoSaveSuggestions(filtered, userDir, skills.ProjectSkillsDir(), resolved.Skills, g, resolved.Guard, false) for _, name := range result.Saved { sm.Notifier.Notify(skills.SkillEvent{ Type: "saved", SkillName: name, Timestamp: time.Now().UTC(), }) } - if len(result.Saved) > 0 { + if len(result.Saved)+len(result.ProjectSaved) > 0 { sm.MarkDirty() sm.Reload() } diff --git a/cmd/odek/telegram.go b/cmd/odek/telegram.go index f8ec0aa..bdda6e8 100644 --- a/cmd/odek/telegram.go +++ b/cmd/odek/telegram.go @@ -2047,13 +2047,18 @@ func handleChatMessage( // Auto-save if enabled if skillsCfg.AutoSave.Enabled { - result := skills.AutoSaveSuggestions(filtered, userDir, *skillsCfg, telegramGuard, telegramGuardCfg, false) + result := skills.AutoSaveSuggestions(filtered, userDir, skills.ProjectSkillsDir(), *skillsCfg, telegramGuard, telegramGuardCfg, false) for _, name := range result.Saved { sm.Notifier.Notify(skills.SkillEvent{ Type: "saved", SkillName: name, Timestamp: time.Now().UTC(), }) } - if len(result.Saved) > 0 { + for _, name := range result.ProjectSaved { + sm.Notifier.Notify(skills.SkillEvent{ + Type: "saved", SkillName: name, Timestamp: time.Now().UTC(), + }) + } + if len(result.Saved)+len(result.ProjectSaved) > 0 { sm.MarkDirty() sm.Reload() // Run micro-curation diff --git a/docs/LEARNING.md b/docs/LEARNING.md index 0e249b2..79a1271 100644 --- a/docs/LEARNING.md +++ b/docs/LEARNING.md @@ -59,6 +59,7 @@ odek run --learn "set up CI with GitHub Actions" - **Auto-curation runs silently** — after every session where skills were saved, overlaps are merged, duplicates removed, and stale skills pruned. - **Learning is non-blocking** — skill detection and auto-save run in a background goroutine after the agent's response is delivered.

Full reference: [docs/SECU - **Audit log** (`cmd/odek/audit.go` + `internal/session/audit.go`) — every `wrapUntrusted` call records source + content-hash + turn into `/audit/.json`. After each turn a divergence heuristic flags `suspicious_divergence=true` when the agent ingested untrusted content AND its actions or final response reference resources that either did not appear in the user's message or were introduced by the untrusted content itself (closing response-only exfiltration and reused-resource injection bypasses). Inspect with `odek audit ` / `odek audit --list`. - **Memory taint** (`internal/memory/provenance.go`) — `EpisodeProvenance` tracks Untrusted/Sources/UserApproved. Tainted episodes are stored but `Search()` filters them out, so a one-shot injection cannot persist via the episode pipeline. User must explicitly promote. - **Skill provenance gate** (`internal/skills/loader.go` + `cache.go` + `tools.go`) — `Skill.Provenance{Untrusted, Sources, NeedsReview}`. NeedsReview skills pin to Lazy regardless of `auto_load` and are excluded from lazy trigger matching (the matchers in `reloadLocked` are built only from promotable skills), so a flagged skill cannot be injected into context on a keyword match. Skills scanned from the project-local `./.odek/skills/` directory are distrusted like `./odek.json`: they are forced to `NeedsReview` with `"project"` in `Sources` until promoted. The auto-save path declines tainted suggestions by default. Agent-created skills via `skill_save` and patched skills via `skill_patch` are forced to `Untrusted` + `NeedsReview`, and `skill_patch` refuses edits that touch the YAML frontmatter, blocking an injected agent from flipping `auto_load` or clearing `needs_review`. All skill-body scans (load, save, patch, suggestion) go through `guard.ScanContentWithScope`, so the fast local rule scan runs even when the `skills` guard scope or the guard itself is disabled; the sidecar second opinion only runs when the scope is enabled (default: on). Taint derives from `memory.ToolCallTaints`, whose always-external set covers `browser` / `http_batch` / `transcribe` / `session_search` / `web_search` / `vision` / `delegate_tasks` (`shell` is deliberately excluded as the primary work tool). `odek skill promote --force` clears the flag after explicit user review. -- **Skill scope gates** (`internal/skills/selfimprove.go` + `curator.go`) — the auto-save pipeline classifies every suggestion by scope before writing. Machine-specific suggestions (`NonReusableReason`: absolute home-directory paths) are dropped entirely. Project-specific suggestions (`ProjectScopeReason`: repo-rooted `./scripts/...` invocations, hardcoded release version tags) are redirected to the project skills dir `./.odek/skills` — project-related skills are never promoted to the global `~/.odek/skills`, and the redirect is refused (suggestion dropped) when the project dir resolves to the same location as the global dir (e.g. odek run from `$HOME`). Post-session micro-curation (`MicroCuration` / `RunAutoCurate` / `ExecuteMicroCuration`) is confined via `Skill.Source.Dir` to skills physically stored under the global dir, so a project skill can never be merged into a global skill or deleted by the curator. `DetectCorrection` additionally requires explicit correction phrases plus a shared lead verb between the corrected commands, and derived trigger keywords filter shell operators, flags, and version fragments — together these suppress the "garbage skill" class (one-off commands saved as reusable knowledge). +- **Skill scope gates** (`internal/skills/selfimprove.go` + `curator.go` + `candidates.go` + `loader.go`) — the auto-save pipeline classifies every suggestion by scope before writing.

Post-session micro-curation (`MicroCuration` / `RunAutoCurate` / `ExecuteMicroCuration`) is confined via `Skill.Source.Dir` to skills physically stored under the global dir, so a project skill can never be merged into a global skill or deleted by the curator. `skill_save` accepts `scope: "project"` and the interactive learn prompt offers `p` for the same boundary; both refuse when no distinct project dir exists. `DetectCorrection` additionally requires explicit correction phrases plus a shared lead verb between the corrected commands, and derived trigger keywords filter shell operators, flags, and version fragments — together these suppress the "garbage skill" class (one-off commands saved as reusable knowledge). +- **Skill save-time hygiene** (`internal/skills/selfimprove.go` + `candidates.go` + `loader.go`) — four gates keep the skill store clean: (1) recurrence: a suggestion must appear in `auto_save.min_occurrences` distinct sessions (default 2) before saving; first sightings are tracked in `~/.odek/skills/.candidates.json` (30-day pruning) and reported as `Pending`. (2) Score ranking: eligible suggestions are sorted by a deterministic substance score so `max_per_run` keeps the strongest. (3) Near-duplicate rejection: stopword-filtered Jaccard word-set similarity ≥ 0.85 against an existing skill in the target dir skips the save (`DuplicateOf`); same-name saves are updates and bypass the gate. (4) Secret scan: `WriteSkill` runs `internal/redact` over body and description — matches are replaced with `[REDACTED]` and the skill is pinned to `NeedsReview`. With `llm_curate`, merge bodies are LLM-synthesized (structure/size sanity-checked, mechanical fallback) while keeping the worst-of provenance union, so a merge can never launder taint. - **Sub-agent damage cap** (`cmd/odek/subagent.go::applySubagentTrust`) — `delegate_tasks` carries `trust_level` + `max_risk`. The mutated `DangerousConfig` is passed into the sub-agent's `odek.Config` so the engine enforces the cap. Untrusted ⇒ NonInteractive=deny, Destructive/CodeExec/Install/SystemWrite/NetworkEgress/Unknown/Blocked all forced to Deny. `max_risk` ⇒ everything above cap forced to Deny. MCP tools are not loaded into untrusted sub-agents, because the MCP `ToolAdapter` does not perform its own danger check and would otherwise bypass the cap. - **FD-based API key handoff** (`cmd/odek/subagent_key.go`) — parent writes key to a 0600 tempfile, immediately `unlink()`s, passes the FD via `cmd.ExtraFiles`. Sub-agent reads from `$ODEK_API_KEY_FD` and closes. Key never in `/proc//environ`. - **Approver friction** (`internal/danger/approver.go`, `cmd/odek/wsapprover.go`, `cmd/odek/shell.go`, `cmd/odek/perf_tools.go`) — both TTYApprover and WSApprover engage friction mode after 3 approvals of the same class in 60s: require typing literal `approve`, 1.5s pause. Trust-class shortcut disabled for `destructive` + `blocked` regardless. CLI `shell`/`parallel_shell` reuse a single TTYApprover instance per process so the counter and trust cache persist across prompts. diff --git a/cmd/odek/main_test.go b/cmd/odek/main_test.go index 6b66768..be73a69 100644 --- a/cmd/odek/main_test.go +++ b/cmd/odek/main_test.go @@ -1396,8 +1396,10 @@ func TestRunLearn_MultiStepProcedure(t *testing.T) { }() // Create local odek.json with auto_save enabled, LLM enhancement disabled - // (mock server can't handle enhancement prompts) - configContent := `{"skills": {"verbose": true, "auto_save": {"enabled": true, "require_llm": false}, "llm_learn": false}}` + // (mock server can't handle enhancement prompts). min_occurrences=1 + // bypasses the recurrence gate — this test covers the save path; the + // gate itself has dedicated unit tests in internal/skills. + configContent := `{"skills": {"verbose": true, "auto_save": {"enabled": true, "require_llm": false, "min_occurrences": 1}, "llm_learn": false}}` os.WriteFile("odek.json", []byte(configContent), 0644) defer os.Remove("odek.json") diff --git a/docs/CONFIG.md b/docs/CONFIG.md index 29b9061..80db941 100644 --- a/docs/CONFIG.md +++ b/docs/CONFIG.md @@ -289,7 +289,8 @@ The `skills` section controls the skill system: "auto_save": { "enabled": true, "require_llm": true, - "max_per_run": 3 + "max_per_run": 3, + "min_occurrences": 2 } } } @@ -313,7 +314,8 @@ The `skills` section controls the skill system: | `curation.skip_reset_days` | — | 30 | Days after which a skip expires (re-allows suggestion) | | `auto_save.enabled` | — | true | Auto-save quality skill suggestions without prompting | | `auto_save.require_llm` | — | true | Only auto-save if LLM enhancement was applied | -| `auto_save.max_per_run` | — | 3 | Max skills to auto-save per session | +| `auto_save.max_per_run` | — | 3 | Max skills to auto-save per session (score-ranked) | +| `auto_save.min_occurrences` | — | 2 | Distinct sessions a pattern must recur in before auto-save (1 disables) | | `embedding` | — | *(inherits top-level `embedding`)* | Optional override of the shared embedding backend for semantic skill matching.
